Leo
Built an AI transcription and research platform for historical documents from scratch, including credit-based billing.
4+ YearsShipping
Architecture, schema, APIs, frontend and the deploy pipeline underneath. Owning the whole surface is what makes a product actually ship.
HeroGeneration, Leo, Magic Makers
Solo buildsTook on sole-developer roles across HIPAA-compliant SaaS, AI transcription, and consumer AI products, architecture through deployment.
Lead engineer, OGE

AI Augmented Engineer
NowWorking across AI integration, full-stack product builds, and cloud infrastructure, mostly solo, always shipped to production.
DailyTools
TypeScript
Default for anything with a frontend or a Node/Nest backend.
Next.js
Default framework for every new product build.
React
Component architecture, state, and everything in between.
Tailwind CSS
Fast, consistent styling without a design-token layer to maintain.
Nest.js
Structured API services with a modular architecture that scales with a team.
PostgreSQL
Row-level security as a default, not an afterthought.
Supabase
Fast to ship on, with auth and storage bundled in.
Docker
Consistent environments from dev through production.
OpenAI & Claude APIs
Multi-provider by default, so one vendor going down shouldn't take the product with it.
RAG
Isolation and per-document tuning, not a single global retriever.
How IWork
Ship to production, not to demo.
Every project listed shipped with real users, real billing, and real monitoring.
AI that's debuggable.
Retrieval and LLM systems built with evaluation, tracing, and fallbacks, not prompt-and-pray.
Own the whole stack.
Schema through deployment. Most of these were built solo, from the first commit.
Built to be audited.
Infrastructure as code, least-privilege access, environments that separate cleanly.

We spent three weeks blaming the prompt. It was the retriever the whole time.
On debugging RAG in production, and why the failure is almost never where you think.

7 things I do differently after 4 years of shipping.
Engineering lessons that only show up after the project has been live for a while.
