Aditya Aggarwal — Senior Backend Engineer

👋 Senior Backend Engineer — Distributed Systems & Data Infrastructure

Backend engineer with 4+ years building and scaling production systems — a 0→1 fraud-detection network over 10M+ data points, an e-commerce platform serving 1M+ users, and a zero-downtime MongoDB → ScyllaDB migration that cut ~$150K/yr. Codeforces Candidate Master.

These days a lot of my time goes into finding and fixing subtle correctness bugs in large open-source AI systems — agent frameworks, inference engines, eval harnesses, and vector / data infrastructure.

🔭 SDE2 @ Uni Cards (fintech)  ·  📍 Bengaluru, India  ·  💬 Ask me about backend architecture, distributed systems & databases
