What I build

AI product engineering

The AI feature itself — built to be reliable from day one, with the evaluation seams already in place so it can be proven later.

#What I build

Conversational assistants / chatbots

RAG over your docs, streaming UI, source citations, and a scope guard so it stays on-topic.

AI voice agents

Inbound + outbound voice that qualifies, books, and follows up — with a hard consent gate on outbound.

Document intake & extraction

Invoices, forms, and PDFs turned into validated structured data, with a review lane for low-confidence cases.

Internal copilots

A private assistant wired into your wiki, code, and tickets — access-scoped and auditable.

RAG pipeline engineering

Chunking, embeddings, hybrid retrieval, reranking, and grounding — with retrieval-quality evals in front.

Multi-agent orchestration

LangGraph-style flows with explicit state, tool boundaries, retries, and approval checkpoints.

#How I build it

  • Structured outputs and function-calling are schema-validated, with fallbacks on parse failure and raw inputs logged beside every decision.
  • Grounding is enforced by construction where it matters — e.g. no uncited generation path — not asked for in a prompt and hoped for.
  • The evaluation harness is designed in from the start, so the feature is provable, not just shippable.

Concretely, an LLM step is a typed, validated function — not a free-text call you hope parses:

classify.ts
const Ticket = z.object({
  category: z.enum(["billing","bug","howto","other"]),
  urgency: z.enum(["low","med","high"]),
  needs_human: z.boolean(),
});

const out = Ticket.safeParse(await llm(prompt, { schema: Ticket }));
if (!out.success) return { category: "other", needs_human: true }; // safe fallback
log({ input, decision: out.data });   // every decision is auditable
Proven in public: a RAG system where 100% of answers cite their source by design — verified live, screenshot on the homepage.
