What I'm looking for

I'm looking to build scalable, high-availability backend and real-time platforms where I can improve performance, reliability, automation, and user impact through strong cross-functional collaboration.

At PT. Hashmicro Solusi Indonesia, I lead backend architecture for ESG, booking, real-time communication, and AI-driven automation platforms serving 10,000+ users. I improved API latency by 30–40% and reduced release time by approximately 50% through Docker-based CI/CD pipelines.

I've built HashMeet with Jitsi for stable concurrent meetings and an AI-powered WhatsApp chatbot processing 100k+ messages each month. Previously, I delivered healthcare, education, HR, medical, warehouse, and government permit-tracking systems using Golang, Laravel, and scalable RESTful APIs.

I focus on reliable, maintainable systems, database performance, and product outcomes that improve how teams and users work.
