I build production full-stack SaaS, AI, and real-time collaboration products.

What I'm looking for

I'm looking to build production SaaS, AI, collaboration, or event-driven products with end-to-end ownership across interfaces, APIs, data systems, integrations, and delivery.

I've built production B2B SaaS applications, AI products, collaborative editing platforms, and event-driven systems for more than five years.

At GetGenAI, I joined as a founding engineer and helped take an AI-powered collaborative editing platform from zero to production. I owned complex React interfaces, APIs, integrations, and persistence flows, including rich-text editor infrastructure using Tiptap, ProseMirror, Yjs, and CRDT synchronization.

I supported delivery to the company’s first enterprise customer while troubleshooting production issues, improving performance-sensitive UI, and iterating rapidly on the product.

Previously, I built AI SaaS workflows with streaming chat and LLM APIs, delivered B2B go-to-market platform features at Ignition, and shipped client applications as a freelance engineer. I also built a real-time analytics platform using FastAPI, Redis Streams, PostgreSQL, React, and Next.js, with idempotent ingestion, retry and recovery paths, Docker services, and GitHub Actions CI.
