My day-to-day work is mostly front-end: React, Next.js, PWAs, Tailwind, and Shadcn UI, built on Turbopack. I care about performance and architecture as much as how something looks, and a background in cybersecurity means I think about data handling and attack surface before I ship, not after.

Over the past while I've been teaching myself the machine learning side properly: preprocessing, feature engineering, training and evaluating models, then the less glamorous part of actually running them, serving through FastAPI or Flask, packaging with Docker, tracking experiments in MLflow, and keeping an eye on things in production with Prometheus and Grafana.

At CV. Digital Awan Nusantara I'm not just writing code. I handle the financial side, client relationships, and product decisions too, which forces me to weigh engineering choices against what the business can actually sustain. The direction I'm working toward is systems where the ML isn't a bolt-on demo but genuinely part of the product.
