Know About Me

Manas Saha Roy (Tripto)

Senior Full-Stack Engineer | Cloud & DevOps Enthusiast

4+ years • Tech Team Lead

Backend-focused full-stack engineer with a passion for building scalable systems, robust APIs, and reliable infrastructure. My work centers on designing architectures that can handle real-world complexity while remaining maintainable and efficient.

I enjoy the intersection of development and operations—optimizing CI/CD pipelines, improving observability, and ensuring systems perform well under pressure. Whether it‘s designing database schemas, building microservices, or setting up monitoring stacks, I approach problems with a focus on long-term sustainability.

Beyond code, I value deep focus, independent problem-solving, and thoughtful engineering decisions. I believe in building things that last and systems that scale—not just in infrastructure, but in team practices and development workflows.
