Who I am
I'm a full-stack engineer and AI researcher based in Addis Ababa, Ethiopia. I hold an MSc in Artificial Intelligence from Addis Ababa University (GPA: 3.94/4.0) and a BSc in Software Engineering from AASTU (GPA: 3.77/4.0).
My research on explainability-driven federated learning was published in IEEE Access (2025) — one of the field's leading peer-reviewed journals.
I currently work as a Software Engineer at CRCC International Consulting (Ethiopian branch), where I am the sole engineer building a company-wide construction ERP. I previously freelanced for YolkWorks (US, remote; Jul 2024 – Feb 2025), taught at Mizan Institute of Technology, and co-founded an IT solutions company where I led end-to-end software delivery for commercial clients.
I write code that the next engineer can maintain, I communicate clearly across timezones, and I don't disappear after delivery.

Client testimonials
“Samuel did an excellent job developing a couple of websites for me. He was professional, responsive, and easy to work with throughout the process. One thing I really appreciated was how well he took feedback and implemented changes quickly without any issues. He paid attention to details, communicated clearly, and delivered quality work. I would definitely recommend him to anyone looking for a reliable web developer.”
“Samuel built our inventory management system from scratch and delivered exactly what we needed. The system handles our stock tracking, supplier management, and reporting workflows seamlessly. What impressed me most was how he understood our business process before writing a single line of code. The UI is clean, our team adopted it with almost no training, and Samuel was responsive throughout. We've been running it in production for several months with zero major issues.”
