Backend Engineer | Python, FastAPI, Distributed Systems | Microservices & AI Platforms

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.
