SOFTWARE ENGINEER
BACKEND | PLATFORM | DISTRIBUTED SYSTEMSEngineering resilient backend platforms for high-throughput financial products.
I'm a creative engineer building production systems with a strong focus on delightful product performance and reliable digital infrastructure.
I currently work as a Software Engineer at CoinDCX, building Futures platform services that require strict data consistency and real-time synchronization. Previously at KreditBee, I built underwriting and OCR systems that improved disbursal capacity, reduced approval times, and lowered manual verification overhead.
