What I'm looking for

I seek roles building scalable cloud-native systems where I can lead architecture, improve observability, mentor teams, and deliver high-quality production services.

I am a Senior Software Engineer with over 8 years of experience building and scaling full-stack systems using Golang and TypeScript (Node.js, Angular, React). I design cloud-native architectures on AWS and GCP, implement observability, optimize performance, and productionize resilient APIs and data-intensive services.

I lead cross-functional teams, author architecture decisions and design documents, mentor engineers, and advocate for test-driven development and CI/CD automation. I deliver practical, high-quality solutions, balancing speed with long-term maintainability while improving system stability and developer productivity.
