About

👋 Hey there! I'm a backend engineer with 3 years 5 months of experience building high-scale payment systems at Dream11 and POP. 💻 I specialize in: 1. Designing microservices for scale and resilience (Kafka, Java, Golang, Redis, MySQL Postgres, AWS) 2. Reconciliation engines that ensure a 100% terminal state on transactions 3. Real-time monitoring using InfluxDB + Grafana 💰 I've built systems that sync payments with gateways, banks, and internal ledgers — with 99.99% accuracy. ✅ I’m currently open to remote roles or freelance projects in fintech, gaming, or high-scale backend systems. Let's connect if you're looking to: 1. Fix flaky payment infrastructure 2. Build fast, scalable backend systems 3. Get someone who understands scale, system design and ownership
