What I'm looking for

I’m looking for a role where I can build scalable web/mobile systems with secure, high-performance architecture, integrate LLM/AI features, and contribute through strong engineering practices like code reviews and mentoring.

I’m a Full Stack Software Developer with 5 years of experience building scalable web and mobile applications using JavaScript, TypeScript, React.js, Next.js, and React Native. I’ve delivered high-traffic products by combining secure backend systems with performance-focused frontend engineering.

At Ellenox, I’ve led development of CourseFinder (Golf.com), including scalable React.js/Next.js and PostgreSQL systems with Row Level Security (RLS), plus SEO improvements for organic traffic growth. I also build AI-driven features—like an AI-powered golf trip planner using LLM recommendations, function calling, and multi-agent workflows—and advanced platforms such as an AI financial analysis system with specialized agents, while mentoring junior developers through code reviews and best practices.
