About Me

I am a Software Developer with over 4 years of experience building business software: ERP, POS, inventory & warehouse management, booking and accounting tools. I work mainly with Vue.js/Nuxt.js on the frontend and Node.js/MongoDB on the backend, and I can own a product end to end, from requirements to deployment.

Beyond code, I have hands-on experience connecting hardware (barcode scanners, printers, payment terminals) into one ecosystem, supporting end users, and troubleshooting software and device issues. I enjoy working with operations teams to turn manual, error-prone processes into software that saves real time.

💡 Mission: I believe great software should not only "work" but also fit how people actually operate: stable, easy to use and easy to maintain. I always strive to build systems that make daily operations faster and more accurate.
