What I'm looking for

I seek a role building low-latency, scalable backend systems and full-stack features at a collaborative company that values performance, reliability, and continuous testing.

I am a full-stack software engineer with hands-on experience building scalable backend systems, real-time integrations, and developer tooling across C/C++ and modern web stacks. I have improved simulation throughput, implemented distributed crawling and indexing services, and contributed to open-source backend reliability.

My work spans performance engineering in C++ for high-frequency simulation and production services, backend API development and debugging with Node.js/Express and PostgreSQL, and cloud-native deployments using Docker, Kubernetes, and AWS. I emphasize reliability: adding automated tests, CI pipelines, and observability to catch regressions early.

I seek roles where I can apply systems-level performance optimization and full-stack product development to deliver robust, low-latency services while mentoring peers and improving engineering processes.
