What I'm looking for

I am seeking senior backend or full‑stack roles where I can design scalable APIs and microservices, lead technical teams, and improve system reliability.

I am a Senior Software Engineer with 9+ years of experience building scalable microservices and high-performance APIs across telecom, fintech, and e-commerce domains. I design production-ready systems that handle millions of transactions and translate complex client requirements into maintainable solutions.

I have led technical teams, mentored junior engineers, and driven improvements in API performance and scalability—working on product catalog, billing, and inventory management systems. I have hands-on experience designing GraphQL APIs and automated network operations and partner integrations.

I actively engage in requirement gathering, client demos, and end-to-end development, and have delivered platforms integrating payments and automated workflows. I emphasize documentation, maintainability, and operational stability in all projects.
