I've built Go-based microservices and real-time business systems for BM Technology, Phibela Industrial, Two F Times Trading, and Milto Labs.

At BM Technology, I develop a multitenant SaaS ERP platform with row-level security, event-driven workflows, gRPC, Protocol Buffers, and optimized database transactions.

At Phibela Industrial, I led a real-time production monitoring system used across 8+ production lines, cutting reporting time from roughly two hours to under five minutes per shift. I also delivered a sales platform processing 8,000–12,000 monthly transactions and sub-second notifications for 50+ users.

I use Go, PostgreSQL, Docker, Kubernetes, React, WebSocket, and Domain-Driven Design to build reliable systems, backed by unit, integration, and load testing.
