What I'm looking for

I’m looking to modernize and scale production systems—building full-stack features, improving performance, and tightening CI/CD—while shipping reliably to real users with strong engineering standards and a collaborative team.

I’m a fullstack engineer with 4+ years building and migrating production web applications, focused on delivering modern, maintainable systems that ship to real users. I architect and ship white-label SaaS solutions, migrate legacy platforms module by module, and refactor CI and test suites to accelerate deployment cycles and cut infrastructure costs.

My work consistently targets performance and reliability: I’ve resolved database bottlenecks, redesigned pipelines for throughput, and decoupled AI workloads using async queues to protect users from external latency spikes. I also bring a strong engineering-standards mindset—Clean Architecture/DDD/SOLID, test coverage with Jest, and CI/CD—so teams can iterate safely while scaling features and services.
