About

I build products end to end: the database schema, the API, the interface and the deploy. Most recently that meant billing, auth and AI pipelines for an ad-tech startup, shipped remotely to a team in the UK.
I like the part of a problem I don't understand yet. Agents, retrieval, real-time chat and payments each started that way, and each one taught me something the last project couldn't.
Outside of shipping, I'm happiest reading about how other people build things: post-mortems, design docs and the occasional rabbit hole that has nothing to do with code.

Built a Stripe-integrated subscription billing system with webhook-driven plan synchronization, checkout deduplication, and a usage-based LLM credits metering system.
Developed end-to-end authentication and onboarding flows using Supabase Auth with email OTP, Google OAuth, org provisioning, and reCAPTCHA v3 bot protection.
Engineered an AI ad creation pipeline generating 3–4 concepts per request using GPT-5 for ideation and GPT-Image-1.5 with Replicate fallback for rendering.
Built product page extraction service using Playwright with HTML pruning and LLM-based parsing to extract product features and images for ad generation.
Architected a multi-agent orchestration system in Python with OpenAI function calling, enabling autonomous and scheduled decision-making over live ad platform data.
Developed a Meta competitor radar platform tracking 100 ads via Ad Library scraping, with LLM-powered hook detection on competitor creatives.
Designed a Redis-backed job scheduling system with user-reviewable job specs, ensuring controlled execution of agent-driven tasks across asynchronous workflows.
