Hi, I'm Hubert.

I'm a software engineer and AI engineer based in Surabaya, Indonesia. I like building systems that are dependable in production: clear APIs, well-modelled data, automated tests, and deployments you don't have to think twice about.

I started as an assistant lecturer at Institut Sains Dan Teknologi Terpadu Surabaya, where I also built a web application for new student registration and administrative records.

As a Senior Software Engineer at PT. Mitra Mulia Makmur, I designed RESTful APIs and backend services in Node.js, built a React web application from scratch, and delivered a handheld warehouse stock management app that replaced manual inventory tracking. I containerized services with Docker and deployed them with Kubernetes on AWS.

My thesis on deepfake detection with LSTM and rPPG got me into machine learning. Today I build AI agents as production systems. The clearest example is the agent pipeline that writes and publishes my blog every day.
