At Nuevo Soft LLC, I developed backend services and core financial logic for the Vataga Trading Platform, a multi-exchange crypto trading platform. I also built an asynchronous balance synchronization service across four exchanges and extracted critical exchange operations into a FastAPI service, reducing Bybit bulk leverage update time across about 500 trading pairs from 1.5–2 minutes to about 2 seconds.

Earlier, I designed a transaction system and payment gateway at BIND, and built a push notification microservice at X5 Retail Group for an employee app used by more than 5,000 employees. My work has also included pharmaceutical marketplace APIs, payment services, and contributing to a legacy billing system migration.
