What I'm looking for

I seek a hands-on engineering role building scalable backend and cloud-native systems, with strong DevOps culture, collaborative product teams, and opportunities to lead architecture and reliability improvements.

I am a Senior Software Engineer with 7+ years building web and mobile applications, focused on backend development, product design, and scalable microservices using Python, Node.js, and AWS. I have led architecture and implementation of microservices, GraphQL gateways, high-throughput data pipelines, and payment/subscription systems while improving CI/CD, observability, and progressive delivery practices.

I have delivered full-stack solutions across startups and enterprises—designing CMS and real-time platforms, shipping cross-platform mobile apps, and integrating authentication, billing, and CRM systems. I collaborate closely with product teams, emphasize TDD/DevOps practices, and prioritize reliability, security, and performance in production systems.
