What I'm looking for

I seek backend/cloud roles where I can design scalable APIs, optimize databases, and improve system reliability within agile, remote-friendly teams focused on measurable performance gains.

I am a backend developer with 5+ years building scalable backend systems for international and remote teams.

I specialize in API design, cloud infrastructure and database optimization, and I've delivered high-quality solutions using Node.js, Go, Python, Ruby, PHP, Java, C#, and Rust.

I've implemented CI/CD pipelines, optimized PostgreSQL and MongoDB performance, and built microservices and serverless data processing that improved processing efficiency and reduced costs.

I thrive in agile environments, enjoy performance tuning and reliability work, and consistently drive measurable improvements in system availability and response times.
