A software builderwho also runs a business
I'm Muhammad Nuur Rohman, the builder behind Lumekara. I combine a background in mathematics with hands-on work building websites, backend systems, and AI automation.
Through Numekara, the education business I run, I build and use the same kinds of systems I deliver to clients, from the website to the backend, online payments, and the AI tutor.
This lets me approach every project from both sides: as the developer, and as someone who depends on the software every day.

Myjourney
From mathematics and analytical thinking to building software for real businesses.
My journey began with a strong interest in mathematics and analytical thinking. Studying mathematics taught me how to break down complex problems, think logically, and approach challenges with structure and precision.
As I explored business operations, I kept seeing the same problem: businesses lose time and customers in the gaps between their website, their tools, and their team. Software and automation can close those gaps when they are built around how the business really works.
Today, I build websites, web apps, backend systems, and practical AI through Lumekara. Numekara gives this work a real operating environment and keeps every project grounded in what businesses actually need.
Myexpertise
Frontend, backend, and AI built together around one outcome: software your business actually uses.
