Hi, I'm Karthik, a full-stack Python developer with a proven track record of delivering robust backend systems and scalable web apps for startups, agencies, and government platforms.
With 6+ years of hands-on experience, I’ve:
✅ Built 15+ real-world Django/Flask apps – from HRM systems to AI-integrated chatbots
✅ Deployed microservices with REST APIs, role-based access, payment systems, and socket-based real-time features
✅ Delivered full-stack solutions using Django, React, Angular, and Streamlit
✅ Successfully completed high-scale projects including Kerala Govt's National Youth Programme, E-Lelam, TripXOXO, and more
✅ Integrated complex APIs for flights, accounting, medicine booking, and subscriptions
✅ Built AI chatbot apps using LangChain, FAISS, LLaMA3, and custom embedding pipelines
✅ Written Python packages, performed code reviews, and mentored dev teams
I’m ready to take your idea and turn it into a working, scalable product—on-time and on-budget.
