Hi, I’m Subrata, a Senior Python Backend Engineer with 7+ years of experience building scalable and reliable systems using Python, Django, FastAPI, PostgreSQL, Redis and RabbitMQ. I mentor developers with 0–5 years of experience in Python backend development, technical interview preparation and system design. I can help you with Python, Django, FastAPI, REST APIs, databases, caching, asynchronous processing, distributed systems and practical AI/LLM integration. My sessions combine focused technical questions, real production scenarios, honest feedback and a personalized improvement plan. My goal is to help you strengthen your fundamentals, communicate technical decisions confidently and become interview-ready.
