8 years of experience designing and deploying mission-critical distributed systems — healthcare, fintech, government. From national platforms in Congo to enterprise projects and UN agency contributions.
Building systems that matter
For 8 years, I have been designing and deploying mission-critical distributed systems in Central Africa and for international clients. Currently Senior Software Engineer at Akieni, I lead nationwide projects: SangVie (blood management for the CNTS), ABIS (biometric identification), SFEC (national electronic invoicing) and Camu (universal health insurance).
Before that, I served as Technical Manager at Ginov for 4 years — offshore development for major French companies: L'Oreal, Onet Technologies via Daxium-Air, real estate groups. I also contributed to UN agencies (UNFPA, UNDP) with EduCovid, a COVID-19 response mobile platform officially launched by Congo's Ministry of Health.
Co-founder of Niochi (African tourism), former lead of the Congo Java User Group, Jakarta EE Ambassador. My approach: delivering reliable systems in connectivity-constrained environments, with a focus on performance and resilience.
