What I'm looking for

I’m looking for a product-focused team where I can ship production web apps quickly, build type-safe APIs, and apply AI to automate workflows—while maintaining clean architecture, strong testing, and real performance/SEO outcomes.

I’m a product-minded Full Stack Developer specializing in production web applications, type-safe APIs, and AI-powered workflow automation. I’ve helped teams accelerate time-to-market by 50% through scalable architecture and custom integrations, including OpenAI + PayPal for a SaaS workflow with structured error handling and asynchronous requests.

In agency and startup environments, I’ve reduced manual work by 80% with an automated invoice system, and improved delivery cycles by 20% by implementing automated E2E test cases using BugBug.io. I also build with performance and usability in mind—designing responsive, SEO-friendly landing experiences and delivering an AI wellness roadmap app with strict MVC using Next.js Server Actions, achieving a perfect 100/100 Google Lighthouse score.
