What I'm looking for

I am seeking a backend-focused engineering role where I can modernize systems, implement microservices, integrate AI tools, and improve observability while collaborating in an agile, growth-oriented team.

I am a backend-focused full stack developer with four years of experience building scalable systems using Node.js, TypeScript, React and Python. I specialize in modernizing legacy codebases, designing APIs, and implementing microservices to improve reliability and performance.

I prioritize clear communication, observability and maintainability, and I seek roles where I can drive architecture improvements, mentor peers, and deliver measurable operational gains.
