What I'm looking for

Senior Software Engineer with 10+ years building scalable cloud-native and distributed systems. Expertise in .NET, Java, Python, React, and TypeScript. Skilled in microservices, APIs, AWS/Azure, Kubernetes, and CI/CD. Experienced in AI/LLM solutions, focusing on performance, reliability, and delivering high-impact, large-scale systems.

I am a Senior Software Engineer with over 10 years of experience designing and delivering scalable cloud-native systems and distributed applications. I specialize in backend development with .NET, Java, Python, and modern frontend technologies like React and TypeScript, and I build microservices and API-driven architectures deployed on AWS and Azure.

I have led design and implementation of LLM-powered and generative AI capabilities, integrated OpenAI APIs and RAG pipelines, and deployed vector-database-backed solutions that improved task completion rates and automation. At Amazon I drove modular microservice adoption, improved observability, and optimized CI/CD and Kubernetes deployments to achieve high reliability and faster release cycles.

I am recognized for strong system design, technical leadership, and mentoring engineers while delivering high-impact, mission-critical platforms. I seek to continue building reliable, performant systems that leverage AI, scalable architectures, and DevOps best practices to solve complex engineering challenges.
