About

Professional summary

I am a Senior Software Engineer with more than six years of experience in backend development, data engineering, system architecture, and cloud infrastructure. I have worked across fintech and automotive software, taking ownership from requirements and system design through deployment, monitoring, and production support.

I specialize in building scalable backend platforms and microservices using Python, FastAPI, Go, and PostgreSQL. My experience includes designing payment integrations, dealer management systems, RFID hardware controllers, data pipelines, and AI-enabled business workflows.

I have built and operated cloud-native systems on AWS and other cloud platforms, with hands-on experience in CI/CD, infrastructure optimization, observability, and distributed systems. I have reduced infrastructure costs through rightsizing, spot instances, and adoption of self-hosted open-source tooling.

I also develop full-stack applications using Next.js, React, and JavaScript/TypeScript. I enjoy creating reusable interfaces, integrating frontend applications with backend APIs, and delivering dashboards, forms, and operational tools that support business users.

I have led teams of engineers through sprint planning, code reviews, technical discussions, mentoring, and hiring support. I work closely with clients and product teams to translate business requirements into reliable technical solutions.

I am an active open-source contributor to FastAPI and Litestar, contributing code, documentation, tests, pull-request reviews, and community support. I am particularly interested in backend engineering, AI engineering, data systems, and cloud infrastructure.
