About

Professional summary

I am a Senior Software Engineer with more than seven years of experience building high-performance distributed systems, scalable backend architectures, and full-stack applications. I specialize in Golang, Python, Rust, TypeScript, and React, with a focus on reliable cloud-native platforms.

I design orchestration layers, microservices, agent runtime environments, and state-management systems for complex SaaS, healthcare, and AI-driven products. My work includes integrating LLM inference pipelines, RAG workflows, NLP models, and multi-agent coordination into production systems.

I have extensive experience with AWS, GCP, Docker, Kubernetes, Terraform, PostgreSQL, Redis, MongoDB, and observability tooling. I prioritize fault tolerance, system health, performance optimization, secure infrastructure, and maintainable API design.

In recent roles, I have delivered distributed infrastructure for content automation, healthcare patient-management systems, billing platforms, and enterprise administration portals. I have led end-to-end development across backend services, frontend interfaces, cloud infrastructure, and data architectures.

I enjoy solving complex engineering problems, improving operational workflows, and collaborating with cross-functional teams. I bring a practical, quality-focused approach to building resilient systems that provide measurable business and user value.
