Backend engineer with production experience building Golang backend services inside a microservices architecture. Most recently Backend Engineer at AssistX Enterprise in Central Jakarta, where I develop, maintain and refactor Go services, build and consume the REST and internal APIs between them, and apply Go concurrency patterns — goroutines and channels — to streaming and video processing workloads. I integrate IP cameras and CCTV into the product by consuming RTSP streams, and I work with unit tests, code review, technical documentation and daily coordination with QA during staging.

I contributed to migrating the company's edge video compression engine from Python to Go, from planning through to the stakeholder demonstration.

I graduated in 2025 with a Bachelor of Informatics from Universitas Amikom Yogyakarta (GPA 3.76, cumlaude). Outside work I build distributed systems of my own — surr, an event-driven AI surveillance platform of four independently deployable Go services that discover each other over a RabbitMQ topic exchange rather than by hardcoded address, and Teras Teknologi, a HackerNews clone on a Golang, PostgreSQL, RabbitMQ and Docker microservices stack. My article on open-set recognition for potato leaf disease identification was published in RESTI, a Q3-accredited journal.
