Senthil Kumar . V

I am a Python Backend Developer with 2.8+ years of professional experience in designing and building scalable, secure, and high-performance backend applications. My expertise includes Python, Django, Django REST Framework, FastAPI, RESTful APIs, PostgreSQL, Redis, Docker, AWS, and microservices. I enjoy solving complex backend challenges, optimizing application performance, and writing clean, maintainable code that follows software engineering best practices.

In my current role, I have developed production-ready APIs, optimized database queries, implemented authentication and authorization, integrated third-party services, and contributed to cloud deployments and CI/CD workflows. I am passionate about continuous learning and actively expanding my knowledge in system design, data structures and algorithms, and modern backend technologies.

I am seeking an opportunity where I can contribute to building scalable products, collaborate with talented engineering teams, and continue growing as a backend software engineer.
