About

I'm a self-taught full stack developer - no formal CS degree, just 10 years of teaching myself by building, breaking, and shipping. I don't stop at "it works" I keep pushing the things I make until they hold up in the real world. I work mostly in TypeScript and Next.js. Most of what I build is real - running in production, taking real payments, used by real people - not demos. A live e-commerce store I built and run that takes real customer orders (Ice Fragrances), a profit-analytics SaaS (True Profit), and an MCP server for semantic code search (codebase-rag-mcp). I also do bug bounty / web security work, which shapes how I build: I think about how things break before someone else finds out for me. Stack I reach for: TypeScript, React, Next.js, Node/Express, Postgres, Drizzle/Prisma, Stripe, Clerk, and AI/LLM integration (Claude API, RAG, vector embeddings, MCP). Everything's on GitHub: github.com/Chri2K02 Currently open to full-time software roles - if you're building something real, I'd like to hear about it.
