Message

At Systex, I built Java-based fraud detection microservices that reduced fraudulent activities by 30%, improved historical transaction retrieval by 35%, and cut database response times by 20% through caching, sharding, indexing, and query tuning.

I'm now leading technical architecture and integration work at Winmate Communications US, where I designed an automated inventory management system, troubleshoot firmware and software issues, and mentor engineers in data structures, algorithms, and system design. I also build high-concurrency systems using Spring Boot, Kafka, Redis, FastAPI, PostgreSQL, Celery, React, and Docker.
