EN·ES·PT

I build AI systems — and prove they work.

One person, full stack: the automation, the voice agent, the assistant — plus the testing and evaluation harness that shows it does what it claims. Most builders can’t verify. Most testers can’t build AI. I do both.

AI quality & evaluation harness

You shipped an AI feature — a chatbot, an agent, a generator. I build the evaluation and regression system that proves it works: automated scoring against a rubric, hallucination and accuracy gates, prompt-regression tests wired into your CI, and a pass/fail report before every release.

everything I build

AI systems

Voice agents

Phones answered, jobs booked, 24/7.

Knowledge assistants

An AI that answers questions from your docs, policies, and past tickets — support deflection and internal Q&A.

Document intake & extraction

Invoices, forms, applications turned into clean structured data automatically.

Lead intake & follow-up automation

Every lead captured, scored, routed, and followed up within minutes.

Workflow copilots

Quotes, emails, and reports drafted automatically inside your existing process.

Content pipelines

Programmatic video and social content generated from your data on a schedule.

Quality engineering

End-to-end test suites from zero

Your critical user flows covered and running in CI, so releases stop breaking.

CI rescue

Flaky, red, slow pipelines made green, fast, and trustworthy.

Mobile app testing

Real-device end-to-end certification for iOS/Android apps.

Release gates & quality dashboards

A clear ship/no-ship signal backed by evidence, not vibes.

Full-stack product builds

Web apps and customer portals

Auth, payments, dashboards — production-grade, not prototype-grade.

Mobile apps

Native iOS/Android, built and shipped through app-store delivery.

Internal tools

The admin panel, ops dashboard, or back-office tool your team keeps doing by hand in spreadsheets.

proof — systems I’ve built and run

every number above is from my own shipped systems — no client names are used without written permission, and none appear here yet

how working with me goes
1 — 15-minute call

You describe the problem. I tell you honestly whether it’s worth automating and what it costs.

2 — fixed scope, in writing

Fixed scope, fixed price, in writing. No hourly meter.

3 — build, test, prove

I build it, test it, and prove it works — you get a working system plus the evidence, not a demo and a promise.

4 — optional retainer

Monthly tuning and support if you want it. No lock-in.

Tell me what’s slipping through the cracks.
