I connect the partsthat make software think.

Next.js, Supabase, and the APIs that make products actually work.

Scroll

Every product is a pile of disconnected systems —payments, comms, data, AI models — until someone wires theminto something that behaves like one coherent organism.

Live physics simulation

The stack, as it actually connects.

Every node below is real — hover or tap one to trace where it's actually been used. Project nodes route straight into the case study.

Selected work

Five systems, wired together.

Timeline

The real sequence.

  1. Foundations

    Full-stack fundamentals

    Years spent building the muscle that now powers every project below: shipping product end-to-end, not just the parts that are interesting.

  2. Marketplace & payments

    Two-sided marketplace infrastructure

    Designed and built the transaction backbone for a physical-ad marketplace — matching, bidding, and payouts wired together as one system.

  3. Real-time sync

    Cross-platform data sync

    Built the sync layer keeping a third-party engagement platform and a product's own membership data in lockstep, in real time.

  4. Multi-agent AI

    Production AI agent orchestration

    Took AI systems past the demo stage — six coordinated agents running in a real product, each with a defined job and a defined handoff.

  5. Bilingual delivery

    Multi-market product delivery

    Shipped a bilingual (ES/EN) product end-to-end, treating localization as a first-class architectural concern, not an afterthought.

  6. Now

    Agentic mobile product

    Current focus: an agentic coding app on mobile — AI systems that act, not just answer.
