The Architect. The Builder. The Human.
Get to know the architect, the builder, and the human
Here's the short version.
I'm the person brought in when systems can't afford to fail — high-traffic WordPress platforms, e-commerce operations in regulated markets, subscription engines where downtime means lost revenue. My bias has always been toward stability and long-term maintainability over clever solutions that break under pressure.
Today that same instinct shapes how I work with AI. I build RAG pipelines, automation workflows, and LLM integrations not as standalone experiments but as extensions of the infrastructure businesses already run on. In 2024, that work earned first place in the ByteDance Global Coze AI Challenge. The point isn't the award — it's that what I built for the contest still runs, still works, and still holds up six months later when nobody is watching.

Where I Can Help
Your AI project stalled after the demo
Most AI integrations fail between proof-of-concept and production. I build RAG pipelines, N8N workflows, and LLM integrations that handle real data, real edge cases, and real traffic — not just demos that impress in a slide deck.
Custom
You need technical decisions made, not deferred
Embedded tech lead for teams that need someone to own architecture, unblock developers, and translate technical tradeoffs into decisions stakeholders can act on. Senior capacity without the full-time overhead.
Retainer
Your documentation doesn't exist — or it's wrong
Technical writing from someone who has debugged the systems they're writing about. API references, integration guides, runbooks, onboarding flows. If the reader gets stuck, that's a writing problem, not a reader problem.
Project-based
Your team keeps missing deliveries and you don't know why
Outside advisory for agencies and IT teams with recurring delivery problems. I find where the process is actually breaking — not just where the symptoms show up — and give you something concrete to change.
