About

Full Stack & Python Backend Developer with 4+ years of experience designing and building scalable, high-performance applications across analytics, ed-tech, e-commerce, and enterprise platforms. I specialize in backend engineering using Python, FastAPI, Flask, Node.js, and microservices architecture, with strong expertise in developing secure REST APIs, optimizing databases, and building production-ready distributed systems. I have hands-on experience working across the full development lifecycle — from designing backend architectures and APIs to deploying scalable cloud-based applications using AWS, Docker, CI/CD pipelines, and modern DevOps practices. My technical expertise spans Python, JavaScript/TypeScript, React.js, Angular, PostgreSQL, MySQL, MongoDB, Redis, and cloud-native technologies. Over the years, I’ve worked on systems that required scalability, reliability, and performance optimization, including applications handling real-time operations, large datasets, and complex business workflows. I enjoy solving backend engineering challenges such as query optimization, API performance tuning, microservices communication, and improving system resilience. Key areas of expertise include: • Python Backend Development (FastAPI, Flask) React Frontend development (functional components,Redux library) • REST APIs & Microservices Architecture • PostgreSQL, MySQL, Redis & SQL Optimization • Distributed Systems & Scalable Backend Design • Docker, AWS, CI/CD & Deployment Automation • Performance Optimization & Production Support • Agile/Scrum Development Practices • Data Processing & Backend Calculations I’m particularly interested in backend systems that solve complex business and analytics problems, especially in domains involving risk, data processing, financial systems, and scalable enterprise platforms. I’m passionate about continuous learning, clean architecture, and building reliable software that delivers real business impact.
