§01 · Positioning

Systems that hold under real tenants, not demo load.

Most full-stack resumes claim frameworks. Mine claims systems that had to work: 25+ SaaS and web applications shipped end-to-end, a national mobile app refactor supporting 100K+ downloads, a WhatsApp AI layer built on MCP and RAG keeping strict data isolation across every tenant it served, and a municipal platform combining web scraping with AI chatbots to turn government documents into plain language.

Alongside the systems work, I've mentored other engineers in React since early in my career. Technical leadership and ownership run through all of it, not just the code, but the decisions behind it.
