Calvin Kinyanjui is an impact-driven electrical and electronics engineer whose work sits at the intersection of technical innovation, climate resilience, and social transformation. In his final year, this blend of technical depth, initiative, and social consciousness came into sharper focus when he was selected by the UNESCO Chair on Climate Change Resilience and Sustainability to lead a team in the UNESCO and ONEPLANET Joint WEF Hackathon, where they emerged as 1st Runners-Up. He further distinguished himself as the founder of LPGuardian, an IoT-enabled LPG safety network engineered to detect gas leaks, automatically shut off gas flow, and broadcast real-time alerts to neighbouring homes. The innovation earned him a 10th-place global finish at the World Engineering Day 2026 Hackathon in Jakarta, Indonesia, and is currently incubated under the PRME Africa Entrepreneurship Competition and Capacity Building Programme by the British University in Egypt. Building on this trajectory of excellence, Calvin has also transitioned from having his project submission recognised in the 2025 edition of the QS Reimagine Education Awards to serving as a judge for the Awards in London, UK. Across these milestones, he has steadily distinguished himself as an engineer committed not merely to building technically sound systems, but to designing practical, human-centred solutions for urgent societal challenges.
