About Ujenyuojo

I design and build backend infrastructure for core banking platforms, financial networks, and regulated environments.

My work focuses on transaction processing engines, ledger management, payment integrations, and distributed service architecture where data integrity, strict concurrency control, and high availability are critical.

I have developed core banking applications supporting branch operations, implemented double-entry ledger and transaction workflows, and integrated payment services including NIBSS Instant Payments (NIP), EasyPay, and CoralPay. I have also worked on telecommunications licensing and billing systems supporting regulatory operations for the NCC.

Publications

I write to share my knowledge, experiences, and ideas with others especially those new to the field. My aim is to break down complex technical concepts into relatable illustrations that anyone can understand. Writing also helps me clarify my own understanding, as I believe that teaching through writing benefits both the reader and the writer.
