What I work on

Three areas where most of my time goes.

AI Systems

Agents, retrieval pipelines, and LLM workflows — built with explicit state and traceable outputs.

  • LangGraph
  • LangChain
  • RAG
  • OpenAI API

Full-Stack Web

Dashboards, REST APIs, and frontends tuned for latency and maintainability in production.

  • Next.js
  • FastAPI
  • MongoDB
  • TypeScript

Engineering

Schema design, indexing, logging, and the boring work that keeps apps fast after launch.

  • PostgreSQL
  • Qdrant
  • WebSockets
  • Git

How I build

A simple loop I follow on every project.

01 / 04

Understand

Problem scope, constraints, and what “done” looks like before writing code.

  • Requirements
  • Data model
  • API contract
  • Success metrics

02 / 04

Design

Interfaces, agent graphs, and system boundaries — visible before implementation.

  • UX flow
  • LangGraph states
  • Component structure
  • Error paths

03 / 04

Build

Ship iteratively on a modern stack with tests and performance in mind.

  • Next.js / React
  • FastAPI
  • Vector stores
  • CI checks

04 / 04

Measure

Latency, Lighthouse, and production logs — then fix what the numbers show.

  • Profiling
  • Indexing
  • Caching
  • Runbooks

04 / 05

Writing

Notes from building with LangGraph, RAG, and full-stack tooling.
