What I'm looking for

I'm looking for remote product-engineering work where I can own full-stack delivery, solve complex user-facing problems, and balance performance, maintainability, and shipping speed with collaborative teams.

At TeaCode, I build full-stack, user-facing products from technical design through deployment, including secure web-to-desktop authentication, Stripe-powered AI credit flows, e-commerce integrations, and client-managed content systems.

I've improved desktop performance scores by 80% through Next.js rendering, caching, data-fetching, and Core Web Vitals-focused practices. I also design API contracts, PostgreSQL and Supabase-backed services, reusable React interfaces, and integrations with Medusa, Payload CMS, OpenAI, Google Business Profiles, Instagram, Facebook, and YouTube.

I enjoy turning complex product requirements into pragmatic, maintainable API, data, and UI solutions while partnering closely with clients and teammates. Alongside software development, I run an independent coaching practice focused on helping people turn self-awareness into clear decisions and lasting change.
