## About

Software Engineer with 3\.5\+ years of experience in backend development, distributed systems, and AI\-driven platforms\. I build scalable Python services, optimize performance, and deliver systems that support real\-world production scale\. I architected and contributed to a microservice\-based AI chat platform, designed to support 15,000\+ users, where I worked extensively on backend API architecture and core platform capabilities\. My work includes: • Designing and implementing scalable backend APIs using Python and FastAPI • Building multimodal support and AI agent workflows • Integrating LLMs using Portkey for model orchestration and observability • Supporting deployment and release workflows for AI backend services I also developed reusable Python libraries adopted across 10\+ internal products, reducing integration effort from \~3 days to \~25 minutes\. Previously, I worked on backend data platforms processing 2M\+ datapoints per month and helped maintain CI/CD pipelines supporting 100\+ daily builds\. I enjoy designing backend architectures, improving system performance, and simplifying complex workflows\. I actively mentor junior developers on Python best practices, clean architecture, and debugging patterns\. I’m passionate about building reliable backend systems, scalable architectures, and high\-performance API workflows, and I’m interested in product\-focused backend or AI platform roles involving system design and scalability\.
