(01)What I do

Three disciplines.

One engineer.

I work across the stack, from the API and the agent to the interface on top.

Backend Engineering

APIs and services that stay up.

TypeScript + NestJS microservices on AWS, Django REST + PostgreSQL, and serverless Lambda: designed for retries, failover, and observability from day one.

~1,500domains served by APIs I built
  • Policy-extraction APIs at Gen (NestJS · AWS)
  • Distributed Playwright automation layer, ~35% faster
  • ImmiScore scoring APIs (Django · PostgreSQL)

AI Engineering

Agents that do real work.

LLM-powered agents built on OpenAI APIs and MCP that act on real systems: monitoring production, classifying failures, drafting fixes, and executing multi-step web flows.

200+sites automated by AI agents
  • AI monitoring agent that triages and fixes regressions
  • AI-agent Unsubscribe Service: 75 → 200+ domains

Self-Healing Monitoring Agent

An LLM agent that watches production, finds the bug, and pushes the fix

Built an AI agent on OpenAI APIs that ingests production telemetry, classifies workflow failures, detects recurring issues, and drafts and pushes fixes, turning hours of manual triage into minutes.

AI Unsubscribe Service

AI agents that navigate real websites to complete multi-step flows

Prototyped a one-click unsubscribe service in which AI agents execute each site's unique unsubscribe flow. The prototype became a product, growing from 75 domains to 200+ and handling multiple flow types.
