Best Graduating Student, IPAM — University of Sierra Leone
I'm Francis Sesay — a Software Engineer and AI Systems Developer from Freetown, Sierra Leone, with over five years building backend-driven applications, intelligent systems, and data platforms that solve real problems in education, enterprise, and the public sector.
I graduated First Class with a CGPA of 3.83/4.0 and was named Overall Best Graduating Student at IPAM, University of Sierra Leone — finishing in the top 1% of 2,600 graduates. My dissertation, an AI-Based Inquiry Chatbot, earned the Best Dissertation Award.
As Founder of Sierra Edutech Solutions and Technical Lead at KNESST SL Ltd, I've mentored over 3,000 learners, collaborated with national institutions like DSTI and MOCTI, and led programs that expand digital inclusion and build the next generation of African technologists.
