Services · the full stack, one operator

Everything I build: scoped & quoted for you.

A full-stack AI studio run by one senior engineer — the range of an agency, the speed and accountability of a single owner. The work is designed to continue as a monthly retainer: a short audit, a first build, then an ongoing relationship where I keep it healthy and ship something new every month. A 35+ capability matrix below, all of it on tap.

Minimum 3-month term, then month-to-month — the monthly proof report is designed to make cancelling the last thing you'd want to do. See the quality standard & SLA →
01: how an engagement goes

A fixed path. A real quote. Evidence at every step.

01

Audit

~1 week · start here

I map your highest-leverage failure — the AI surface, the test gap, the automation ROI — and hand you a prioritized plan and a concrete quote you own.

02

Sprint

~2 weeks · scoped

One visible, production-grade improvement: real code, deployed, measured. A minimum viable gate, or a shipped workflow.

03

Build

~4–8 weeks · scoped

The full system: the eval battery, the CI gate, the automation, the runbook, owned by your team at handoff.

04

Operate

ongoing · optional

Measure, improve, publish. The system stays green and compounds instead of quietly decaying.

Priced to your problem — not a package

Small fix or full build — scoped to your budget.

From a quick automation for a small shop to a full system for an AI team — you only pay for what you actually need. The fastest way to a real number is the 2-minute scoper: answer a few questions and get a custom estimate, no call required.

✓Every engagement is quoted in writing before work starts: fixed scope, never open-ended hours. The audit fee credits straight into the build if you continue. Your repo, your CI, nothing retained after handoff. If scoping shows I can't help, I'll say so and it costs nothing.

03: the full capability matrix

35+ things I can build for you.

The five above are where most work starts — this is the full range behind them. Expand a track to open it, filter to narrow, and click any card for the explainer: what it is, what you get, and the outcome. Every one ends in a quote, worked out on a call.

01

AI Build

7 capabilities

The AI feature itself. Assistants, agents, and the retrieval underneath it.

AI Build

Conversational assistant / chatbot

A support or product chatbot grounded in your own docs.

A retrieval-augmented assistant that answers from your documentation, policies, and past tickets, never the open internet. Streaming UI, source citations, and a scope guard keep it on-topic.

→ support deflection + instant internal Q&A
Get a quote for this →
AI Build

AI voice agent

Inbound + outbound voice that gets tasks done.

A phone agent that answers 24/7, qualifies the caller, books the job, and texts you a summary. Or makes outbound reminder and follow-up calls. Human-sounding, with a hard consent gate on outbound.

→ zero missed calls, zero missed jobs
Get a quote for this →
AI Build

Document intake & extraction

Invoices, forms, PDFs → clean structured data.

An extraction pipeline that turns messy documents into validated structured records, schema-enforced, with confidence scoring and a human-review lane for the low-confidence cases.

→ no more manual data entry
Get a quote for this →
AI Build

Internal copilot / knowledge assistant

An AI that knows how your company works.

A private assistant wired into your wiki, code, and tickets so your team gets answers in seconds instead of pinging the one person who knows. Access-scoped and auditable.

→ onboarding + tribal knowledge, solved
Get a quote for this →
★ flagship

RAG pipeline engineering

Retrieval that actually retrieves the right thing.

The unglamorous core that makes AI features trustworthy: chunking strategy, embeddings, hybrid retrieval, reranking, and grounding, with retrieval-quality evals (context precision/recall, citation coverage) in front.

→ answers that cite their sources
Get a quote for this →
AI Build

Multi-agent workflow / orchestration

Agents that plan, call tools, and hand off safely.

When the logic is genuinely agentic, a LangGraph-style orchestration with explicit state, tool-use boundaries, retries, and approval checkpoints. It's instrumented so you can see every step it took.

→ complex flows, kept auditable
Get a quote for this →
AI Build

Structured-output & function-calling

Make the LLM a reliable part of your backend.

Schema-validated LLM steps with function/tool calling, fallback labels on parse failure, and raw inputs logged beside every decision. The difference between a demo and production.

→ AI you can call from code
Get a quote for this →
02

Eval & QA

7 capabilities

Proof it works: golden sets, safety batteries, and the CI gate that blocks a bad change.

★ flagship

LLM evaluation harness

Golden set + LLM-as-judge scoring for your feature.

50–200 real inputs with agreed-good outputs, versioned next to the code, scored by an LLM judge for faithfulness, relevance, and safety. The regression signal you don't have yet.

→ ship prompt changes with a regression signal
Get a quote for this →
Eval & QA

AI red-team & safety battery

Adversarial probes: injection, jailbreak, PII, toxicity.

A battery of adversarial runners that try to break your assistant the way a real user (or attacker) would: prompt injection, jailbreaks, PII leakage, toxicity, over-refusal, with verbatim transcripts of every failure.

→ find the embarrassing failure first
Get a quote for this →
Eval & QA

CI quality gate for AI

A bad AI change blocks the merge instead of showing up in the retro.

Your eval suite wired into CI so it runs on every PR. A score below the ratcheted floor fails the build, with a scorecard your PM can actually read.

→ regressions caught before customers
Get a quote for this →
Eval & QA

Hallucination / grounding gate

Stop it inventing facts and policies.

A grounding layer that binds answers to a source of truth and an eval that fails when the model states unverifiable specifics. The fix for "it made up a refund policy."

→ facts, or a clean "I don't know"
Get a quote for this →
Eval & QA

Prompt & model regression testing

Know exactly what the model bump broke.

A/B and before/after evaluation across prompt and model versions, so a provider update or a prompt tweak comes with a concrete diff of what improved and what regressed.

→ safe upgrades, measured
Get a quote for this →
Eval & QA

Agent evaluation

Did the agent use the right tool and finish the task?

Task-success and tool-use-correctness evals for agentic systems: did it call the right function, with the right args, and complete the job. Scored against a rubric, run repeatedly.

→ agents you can trust to act
Get a quote for this →
Eval & QA

LLM observability & cost monitoring

See quality, drift, and spend in production.

Tracing, per-run cost tracking, and drift monitoring on your live AI feature so quality decay and runaway spend surface on a dashboard instead of in a customer complaint.

→ production AI you can watch
Get a quote for this →
03

Test Automation

8 capabilities

The deterministic surface: E2E coverage, CI wiring, flake protocol, performance baselines.

★ flagship

E2E test automation (Playwright)

Your critical flows, covered and green in CI.

A risk-scoped Playwright (or Cypress) suite with Page Object Model, fixtures, trace-on-retry, and four reporters. Built in your repo, so releases stop breaking in ways users find first.

→ releases that stop breaking
Get a quote for this →
Test Automation

API & contract testing

Catch the broken endpoint before the frontend does.

Contract and integration tests for your APIs: schema validation, auth paths, error cases, and backwards-compatibility checks wired into CI.

→ no more silent API breaks
Get a quote for this →
Test Automation

Mobile real-device certification

Ship iOS/Android with proof it actually works.

End-to-end certification on real devices. The flows a simulator lies about. I've run 256-screen device-cert passes with retry-clean flake handling.

→ app-store confidence
Get a quote for this →
Test Automation

CI/CD pipeline + test wiring

A green badge that actually means something.

GitHub Actions (or your CI) set up from scratch or rescued: parallelized runs, artifact retention, required checks, and the gates that make merge-green trustworthy.

→ a pipeline you believe
Get a quote for this →
Test Automation

Flaky-test stabilization

Make red mean something again.

The flake protocol installed on your existing suite: quarantine lane, retry policy, isolation fixes, and a weekly triage ritual. At HighStrike this cut a live suite from 10% flake to under 1%.

→ red = a real bug, every time
Get a quote for this →
Test Automation

Performance & load baselines

Know your critical path's breaking point.

k6 load baselines on the flows that matter, with budgets wired into CI so a performance regression trips the gate before it trips your users.

→ performance you can defend
Get a quote for this →
Test Automation

Visual regression testing

Catch the layout break a unit test can't see.

Screenshot-based regression across breakpoints and themes, so an unintended visual change is flagged in the PR instead of in a customer screenshot.

→ pixel-level release safety
Get a quote for this →
Test Automation

Accessibility (a11y) audits

WCAG compliance, keyboard, contrast, reduced-motion.

Automated + manual accessibility review against WCAG 2.2: keyboard navigation, screen-reader semantics, contrast, and reduced-motion behavior, with a prioritized fix list.

→ usable by everyone, and compliant
Get a quote for this →
04

Automation

6 capabilities

The repetitive work, automated end-to-end and owned by your team.

★ flagship

Workflow automation

n8n / Make / Zapier, or code when it earns it.

The repetitive back-office flow, automated end-to-end in tools your team can own after I leave. Make/Zapier for linear flows, n8n for branching, code when the logic is genuinely complex.

→ hours of manual work, deleted
Get a quote for this →
Automation

Lead capture → qualify → route

Every lead caught, scored, and followed up in minutes.

An intake pipeline that captures every lead from every source, scores and routes it, and triggers follow-up within minutes. Nothing slips into a spreadsheet nobody checks.

→ nothing slips through
Get a quote for this →
Automation

Data pipelines / ETL

Move and shape data reliably, on a schedule.

Extract-transform-load pipelines with validation, idempotency, and alerting, so the report your business runs on is built on data that's actually correct and fresh.

→ trustworthy data, automatically
Get a quote for this →
Automation

Integrations (CRM, tools, APIs)

Make your tools finally talk to each other.

Connect the CRM, the billing system, the support desk, and the spreadsheet into one flow with proper error handling and an audit trail. No more copy-paste between tabs.

→ one connected system
Get a quote for this →
Automation

Monitoring / scraping / alerting

Watch a source, act when something changes.

Scheduled monitoring of a website, feed, or metric with structured extraction and alerting, so you hear about the change that matters the moment it happens.

→ eyes on it, so you don't have to be
Get a quote for this →
Automation

Scheduled jobs & back-office automation

The recurring task nobody wants to remember.

Cron-driven jobs for the invoicing, reporting, cleanup, and reconciliation work that eats your week: reliable, logged, alert-on-failure.

→ the busywork runs itself
Get a quote for this →
05

Product

4 capabilities

The application layer everything else runs inside: apps, tools, APIs, dashboards.

★ flagship

Web apps & customer portals

Auth, payments, dashboards, production-grade.

The real thing: authentication, payments, dashboards, and the boring-but-critical parts done right, on Next.js + Supabase or your stack.

→ a product you can ship to customers
Get a quote for this →
Product

Internal tools / admin panels

Replace the spreadsheet your team runs by hand.

The admin panel, ops dashboard, or back-office tool your team currently operates in a fragile spreadsheet, built properly, with the right permissions and audit trail.

→ automate the manual ops
Get a quote for this →
Product

APIs & backends

The service layer everything else depends on.

REST or typed APIs with validation, auth, rate limiting, and tests. The dependable backend your app, your integrations, your automations all build on.

→ a backend you can build on
Get a quote for this →
Product

Dashboards & data visualization

Turn your raw data into a decision you can act on.

Institutional-grade dashboards and visualizations treated as part of the design system. The metric your team argues about, made legible and live.

→ decisions from data, at a glance
Get a quote for this →
06

Brand, Content & Growth

7 capabilities

Brand, content, and lead-gen — built the way an automation engineer builds: as systems and pipelines, not one-off gigs.

★ flagship

Brand & design system

A real design system, not just a logo.

Design tokens, a component library, and a typography + motion language — the same system discipline behind this site and the products I run. Built so your team ships on-brand without a designer in the loop for every asset.

→ on-brand at scale, no design bottleneck
Get a quote for this →
Brand, Content & Growth

Content engine (YouTube / social)

A repeatable content machine, not one-off posts.

Research → script → thumbnail → publish, wired as a pipeline. The system that turns your expertise into a consistent publishing cadence — the AI does the heavy lifting, you approve the output. The same machine I run for my own channels.

→ a consistent cadence without a content team
Get a quote for this →
★ flagship

AI video & motion pipeline

Explainers and reels, generated on a pipeline.

Code-native motion plus AI voice (your cloned voice or a pro VO) that turns a script — or a URL — into a finished explainer or promo. The exact pipeline behind the videos on this site. Batch-render a slate, not a one-off.

→ video at the speed of code
Get a quote for this →
Brand, Content & Growth

Short-form / reels at scale

Educational short-form, templated and batched.

A reusable reel template plus a content catalog, so you produce dozens of on-brand vertical videos from one system instead of editing each by hand.

→ a reel library, not a single reel
Get a quote for this →
Brand, Content & Growth

Lead-generation funnel

Capture → qualify → route → nurture, automated.

The full inbound machine: a scoping/qualification flow, lead capture wired to your CRM, and a gentle nurture sequence — the same funnel discipline running on this site. Every lead caught, scored, and followed up in minutes.

→ no lead slips through
Get a quote for this →
Brand, Content & Growth

Outbound & 1:1 video outreach

Personalized outreach that actually gets replies.

Per-prospect landing pages plus a 1:1 video-outreach workflow — the highest-reply tactic there is — semi-automated so you send at volume without the copy-paste, built on real prospect research rather than spray-and-pray.

→ outreach that converts, not spam
Get a quote for this →
Brand, Content & Growth

Thumbnail & creative systems

A thumbnail engine, not a Canva tab.

A manifest-driven system that generates on-brand thumbnails and creative at scale from a template plus data — so every video and post looks intentional without a designer per asset.

→ creative at scale, on-brand
Get a quote for this →
