Why talk to me

I ship AI features with the boring-but-critical parts done: approvals, permissions, audit logs, tests.
I've owned a product end to end — from the first commit to payments, invoicing and on-call.
5+ years of Node.js / TypeScript on AWS, serving hundreds of thousands of end users.

Featured case study

An AI operations agent that can't go rogue

At Furavo I built an agent that runs real e-commerce operations — orders, shipments, carrier costs — while keeping a human in control of anything that writes or spends.

No tool calls yet.

What made it production-grade

Human-in-the-loop

Every write action and bulk external query pauses for approval. State survives the pause via LangGraph checkpoints in PostgreSQL.

Least-privilege SQL

The agent connects with a restricted Postgres role; column-level grants make customer PII physically unreadable.

Append-only audit log

Every tool call — allowed, denied or rejected — is recorded with arguments and outcome.

Provider-agnostic LLM layer

Anthropic, OpenAI and DeepSeek behind one interface, SSE streaming, and the model locked per conversation.

Tested like a backend

Vitest + PGlite permission tests run real SQL against the restricted roles, so guardrails can't silently regress.

Wired into the business

PayTR, Navlungo, e-Archive invoicing, Meta CAPI / TikTok attribution and daily profitability reporting.
