Founder & CEO STEA
01 ROOTED IN TANZANIA. 02 LEARNING IN CHINA. 03 BUILDING FOR THE WORLD.

MY STORY

I’m Isaya Hans Masika, a Tanzanian technology builder studying Computer Science and Electronics in China. What started as curiosity became a habit of turning ideas into websites, applications and practical digital products. I use modern development and AI-assisted workflows, but the goal is never simply more code — it is understanding the problem, choosing the right tools and building something people can actually use. Tanzania is where I started. China is where I’m learning. The world is where I’m building toward.
