About

Backend-first engineer focused on scalable systems and measurable reliability.

Software engineer with 5+ years of experience building scalable backend systems and cloud-native applications. I specialize in designing high-performance APIs and distributed systems that handle real-world production workloads. My core stack includes Node.js, TypeScript, and modern backend architectures, with experience across AWS, Docker, and CI/CD pipelines. Recently, I’ve been working on integrating Generative AI into production systems—building intelligent workflows, LLM-based agents, and automation pipelines.
