I’m Rajan, a backend engineer with strong experience in REST APIs, FastAPI, Django, and Python. I focus on building clean, scalable, and reliable systems. I’ve worked on data modeling, NLP, sentiment analysis, and use tools like Pandas, NumPy, Kafka, PostgreSQL, MSSQL, NoSQL, and Firebase in real projects. I enjoy designing system architecture, optimizing APIs, improving database structures, and helping others solve backend or data-related problems. If you want guidance with backend development, API design, scalability, or data workflows I’m here to help.
