About Me

Senior Backend & AI Engineer with 7+ years of experience designing scalable microservices, distributed systems, and production-grade AI automation platforms.

Strong expertise in Python, event-driven architectures, and LLM-powered workflows, including agent-based systems built with LangChain and LangGraph. Experienced in deploying cloud-native infrastructure on AWS and integrating intelligent automation into enterprise FinTech and Intelligent Document Processing environments.

I thrive in dynamic environments, balancing technical depth with strong communication and an innovation-driven mindset — with a track record of delivering measurable, impactful solutions.
