Backend • DevOps • Platform Engineering
Yasar Arafath
Architecting high-performance backend systems, designing resilient database schemas, and building infrastructure that scales — from zero to millions of users.
About Me
I build backend systems and infrastructure. APIs, databases, container orchestration, CI/CD — whatever it takes to ship and run reliable software at scale.
Currently working with Node.js, Python, and Go. I design for observability, optimize for performance, and automate everything that can be automated.
