What I'm looking for

I seek roles where I can build scalable backend systems, lead engineering efforts, mentor teams, and improve reliability via cloud-native CI/CD and automation.

I am a senior software engineer with 7+ years’ experience building scalable backend and full-stack applications using Node.js, Go, React/Next.js and modern cloud tooling. I design and deliver reliable APIs and microservices, optimize performance, and automate deployments to support B2B SaaS and high-availability platforms.

At Outliant I designed REST APIs with NestJS and PostgreSQL and implemented an AWS-based CI/CD pipeline that increased deployment reliability by 40%. I have led teams, mentored junior engineers, and performed code reviews across multiple active development teams.

Previously I built high-uptime Node.js systems for food delivery, integrated mapping and POS services to improve delivery accuracy, and created booking engines using Express.js and SOAP APIs, reducing legacy bugs and improving maintainability.
