At QT Global Software, I contribute to production-level software solutions on live client projects, including backend development and interactive user interfaces.

At Isonga Cyber Hub, I built cybersecurity-focused tools and collaborated on UI/UX improvements and backend security hardening.

On Calm-Craft, an AI stress-management platform, I integrated machine learning models for emotion detection and applied data analysis to improve user experience and system accuracy.

I also assisted with internal software tools at Lolc Unguka Finance, gaining experience with database management and large-scale data handling. I represented Rwanda in an international competition in IoT, embedded systems, programming, and design, earning first place.
