Software Engineer - Backend & Data Engineering
I'm a backend and data engineer with over 3 years of experience at PixDynamics Pvt. Ltd., where I successfully delivered a 40% throughput increase on a high-volume insurance document automation platform. My work spans building AI-driven orchestration systems and scalable microservices, including projects like Launchbox, a self-hosted PaaS, and Indic-OCR, a multi-language OCR system. I'm focused on deepening my expertise as a backend developer, leveraging my skills in Python and FastAPI to create innovative solutions that drive efficiency and impact.
