I’m a Senior Backend Engineer with 5+ years of experience building scalable systems for US-based startups.

I specialize in Node.js and TypeScript, with a strong focus on distributed systems, event-driven architectures, and real-time platforms. Recently, I led the development of a dynamic pricing system that directly impacted company revenue and built an AI-powered automation pipeline that reduced manual operations by 70%.

I enjoy working on complex backend problems, designing systems from first principles, and collaborating closely with product teams to deliver high-impact solutions.

I’m currently looking for remote opportunities where I can contribute to building scalable, well-designed systems and take ownership from architecture to production.
