What I'm looking for

I seek backend roles focused on scalable systems, event-driven architectures, and cloud-native automation where I can optimize performance and mentor engineers.

I am a Golang developer with over four years of experience designing and deploying scalable backend systems for CRM, e-commerce, and warehouse management. I engineered a no-code platform handling ~1M daily requests, led a hardware rental project managing 15,000 devices, and improved performance and reliability across multiple high-traffic products.

I specialize in building event-driven, microservices architectures using OpenFaaS, Kafka, gRPC and cloud services (AWS). I mentor engineers, drive automation of deployment pipelines, and consistently deliver optimizations that reduce latency, increase throughput, and improve operational efficiency.
