@ FRANZER OÜ
I'm Inefable Koumba, a Software Developer and Technical Lead based in Brazzaville, Republic of the Congo. Working as the Lead Developer at FRANZER OÜ, I design, architect, and deploy enterprise platforms, high-performance mobile applications, and resilient cross-border payment solutions across Africa and Europe.
My profile is defined by a rare triad of technical disciplines: full-stack and mobile platform engineering (Go, Flutter, React Native, Next.js), a rigorous foundation in Data Science & Statistical Analytics (triple-certified by SAS Institute in predictive modeling and business intelligence), and low-level infrastructure expertise in Linux systems administration and network protocols.
Holding a Licence (B.Sc.) in Systems & Network Administration from ESGAE (Brazzaville), I am currently completing a Bachelor of Science in Software Development at Brigham Young University – Idaho (USA).
