Motlalepula Mojatau | Full-Stack Developer for Web, Mobile, and AI Projects

About Me

A developer focused on solving real business problems with scalable software.

I build reliable web and mobile solutions with a growing focus on AI-assisted tools, system design, and security-aware development.

My background

I’m a full-stack developer from South Africa who enjoys turning ideas into real, usable products. I focus on building solutions that solve practical problems and deliver measurable value.

I currently freelance with Tobun & Tobun , contributing to client-facing systems across Flutter, Node.js, PostgreSQL, and the modern web stack.

I’m also part of a YES Work Integrated Learning program at Tirhelo under Afrika Tikkun , where I contribute to a production loan management system—building features, resolving bugs, supporting users, and assisting with reporting workflows.

My interests sit at the intersection of software engineering, AI, cybersecurity, and scalable systems. I aim to grow into an engineer who not only builds features, but understands systems, performance, and real-world impact.

End-to-end development experience across frontend, backend, and mobile applications.
Real-world exposure to client projects, debugging, and production support.
Strong understanding of APIs, dashboards, business workflows, and system integration.
Continuous upskilling in AI, cybersecurity, and modern engineering practices.

Experience
