Chibuzor Ezeamaku Selected Work

Selected case studies.

Most of these systems live in private repositories — client work, internal platforms, things I can’t open-source. So instead of code, here’s the thinking: the problem each one solved, the architecture decisions behind it, and the impact it shipped. Open any case study for the full breakdown.
