Everyone is watching the models. The part that decides whether a product lives is the part nobody films: what the system does when retrieval comes back empty, when the context window fills, when the answer is confident and wrong.

Teaching a machine to sound certain is the easy half. The hard half is deciding what it does when it should not be.

On AI, and what comes after the demo
01

My day runs in TypeScript, Next.js, React, Node.js, Python and FastAPI, on PostgreSQL and MongoDB, deployed to AWS and Vercel. The AI half covers retrieval pipelines, LangChain agent workflows, vector embeddings, semantic search and prompt design against the OpenAI API.

02

The parts that rarely make a headline are the parts I care about. Relational schemas that hold up under load. REST boundaries that let one service scale without dragging the rest along. JWT, OAuth 2.0 and role based access that survive a real multi tenant tenancy model. Query plans that stop a dashboard from timing out.

03

Before that I was the only developer on Ezly and GlanceAI at Silverthread Labs, which is where I learned what owning a release actually costs.

Every role, in order

One current position, a contract that ran alongside it, one long run at Silverthread Labs, and the internship that started it.

    Full Stack AI Engineer

    • eCommerce platforms and internal tools on Next.js, React, TypeScript, Node.js, Python and FastAPI, covering order management, shipping, support and daily operations.
    • AI features over PostgreSQL databases holding millions of customer records, so staff query business data in plain language instead of writing SQL.
    • An AI content management system that absorbs repeat internal work for the operations team, plus cross department automation on LangChain and n8n.
    • Shopify and ShipHero wired into internal services so order fulfillment and inventory stay in sync without manual entry.

    NESL-IT

    Full Stack Engineer, Contract

    • Sole developer on AI SaaS products, owning system design, database schema, frontend, backend and production release.
    • LLM pipelines and agent workflows on LangChain and the OpenAI API, for work that previously needed a person at every step.
    • Modular Node.js services along microservices lines with clear REST boundaries, so parts of the product scale on their own.
    • Frontend in Next.js and React with TypeScript: authentication, dashboards, and the screens users sit in all day.
    • CI/CD through Vercel and GitHub Actions, so releases repeat without a checklist.

    • SEO focused Next.js applications on SSR and SSG, with Core Web Vitals watched after every release.
    • Authentication written from scratch: JWT flows, Better Auth sessions, OAuth 2.0 and role based access for multi tenant SaaS.
    • REST APIs and backend services in Node.js and Express on PostgreSQL through Supabase and NeonDB, with relational schema design and query optimization.
