ABOUT ME
IBM Alum, Quality-Obsessed Software Engineer, Full Stack Web Developer
IBM Alum, Quality-Obsessed Software Engineer, Full Stack Web Developer
Senior full-stack engineer who helps teams stabilize, extend, and ship TypeScript products without creating a maintenance trap. I bring 15+ years across IBM, Duke University School of Nursing, and early-stage startups.
I work across React, Next.js, Node.js, Firebase/PostgreSQL, Vercel/AWS, and integrations including OpenAI and Stripe. Recent work includes modernizing an inherited Node.js API with TypeScript, building Next.js administration workflows, establishing Playwright and Schemathesis coverage in CI, developing multimodal AI products, and shipping Flutter/Firebase and React Native applications.
Best fit: teams that need a senior individual contributor to take ownership of an ambiguous system, introduce appropriate engineering guardrails, and deliver maintainable features.
