WHO I AM

I'm Lisbon Tahwineyi, a Java Software Engineer and Aspiring AI Specialist based in Cape Town, South Africa, with 5+ years delivering enterprise systems that scale reliably under pressure.

Currently a Product Specialist at MasterGradeIT, I bridge the gap between deep technical engineering and knowledge transfer — delivering Java, Python, and Generative AI training to top universities and corporate clients across South Africa, including TUT lecturers and multi-org AI workshops.

My engineering background spans Spring Boot microservices, Oracle PL/SQL optimisation, fintech API integrations, and enterprise support — anchored by a relentless focus on clean architecture and measurable outcomes. I hold an MSc in Software Development, with Microsoft AI certifications on the way.

Whether I'm architecting a scalable backend, building an agentic AI pipeline, or mentoring the next generation of engineers — I bring technical precision and clear communication to every engagement.
