What I'm looking for

I’m looking for a role where I can build scalable, high-traffic backend systems and full-stack experiences using microservices, event-driven design, and cloud infrastructure—while owning performance, reliability, and CI/CD automation from end to end.

I’m a senior backend-focused full-stack engineer with 9+ years of experience building scalable microservices and distributed systems using Node.js, TypeScript, and AWS. I design and deliver APIs, event-driven architectures, and cloud-native data pipelines with a strong emphasis on performance optimization and stability.

In my most recent role, I improved platform maintainability and reduced regression issues by 30% through better architecture patterns and automated Jest coverage. I also enhanced onboarding and activation—cutting early friction by 40%, increasing engagement by 35%, and improving activation by 20%—while strengthening secure cross-system access using OAuth and JWT.
