Message

I’m a Software & Security Engineer focused on building practical software and making the systems behind it more secure.

My work sits at the intersection of backend development and cybersecurity. I enjoy building APIs, working with databases, designing authentication systems, and thinking about how applications can be made more reliable and resilient against real-world threats.

I have hands-on experience with Python, JavaScript, Node.js, Express, MongoDB, MySQL, Git, GitHub, Linux, C++, and Java. I’ve worked on projects involving backend systems, REST APIs, authentication, automation, application security, and secure data handling.

I’m currently studying Software Programming at Rwanda Coding Academy, where I continue to strengthen my foundation in software engineering, computer science, and cybersecurity through hands-on projects.

I’m always learning, building, and looking for opportunities to solve meaningful technical problems. My goal is to become an engineer who builds software that is not only functional but also secure, reliable, scalable, and trusted.
