About

I build production backend systems at the intersection of fintech and AI.Over the past 2 years at Creditas Solutions, I've shipped systems that run in real bank workflows — AWS Lambda orchestration for loan and payment flows across 3+ banks, BillDesk payment gateway integration with reconciliation pipelines, a legal automation engine for compliance notice generation, and an async billing architecture handling 20–30M SMS/month. On the AI side, I've designed and built two multi-agent LLM systems as applied projects: Altron, a loan advisory assistant (intent detection → parallel LLM prompts → synthesis), and ADX Bank — a full banking backend with a RAG-powered multi-agent AI assistant using ChromaDB, sentence-transformers, and a Groq → OpenAI → Claude fallback chain. Both are personal projects; my production work is in fintech infrastructure.LeetCode Knight — rating 1852, 431 problems solved (69 Hard), top 5.9% globally.JEE Mains AIR ~3300 (top 0.3% of 1.2M+ candidates).
