Backend Engineer • Java | Spring Boot | Microservices | REST APIs • Built systems powering India’s first digital pilot licensing platform

About

I build backend systems that actually matter. As a Software Engineer at TCS, I contributed to India's Electronic Pilot License (EPL) platform — making India the 2nd country globally (after China) to digitize pilot licensing under ICAO international standards. That's the kind of scale and responsibility I bring to every project. My stack: Java · Spring Boot · REST APIs · MySQL · Microservices · React Beyond my day job, I build things independently: → RAG-based PDF chatbot using LangChain, FAISS, HuggingFace + Google Gemini → Personal portfolio with ATS-optimized resume tooling → Actively deepening expertise in system design & DSA I'm targeting backend/full-stack SDE roles at fintech and product companies where engineering quality is non-negotiable — think Razorpay, PhonePe, BlackRock-tier environments. If you're hiring for strong Java backend engineers who are hungry, ship fast, and care about craft — let's talk. 📬 sahilsachdeva1109@[your email] | github.com/sahilsachdeva1109
