About

Developer, educator, technology enthusiast.

Background

Fullstack Developer at Polytron Indonesia with 2+ years building enterprise applications. Experienced in performance optimization, warehouse automation, RPA, and AI-assisted development.

I'm a Fullstack Developer at PT Hartono Istana Teknologi (Polytron Indonesia), with experience developing and maintaining enterprise applications across Sales, Warehouse Management, After Sales, and Production. My work focuses on building reliable applications, improving system performance, and streamlining business processes. I've contributed to application performance improvements of up to 20–50%, warehouse automation initiatives that reduced stock-checking time by 50–80%, and RPA implementations using Microsoft Power Automate. I have also been involved in introducing AI-assisted development practices through internal training and knowledge sharing. Outside of software development, I enjoy exploring hardware, building PCs, and helping others find suitable computer setups based on their needs.

Philosophy

I believe good software is software that solves real problems — not software that demonstrates technical complexity for its own sake. Maintainability, clarity, and practical value come first.

I approach technology as a tool for improving workflows and creating tangible outcomes, whether that's a web application that saves hours of manual work, a mobile app deployed for live operations, or a PC build that genuinely fits someone's needs and budget.
