I built a secure QR Smart Bracelet gateway linking 2,000 students to an existing school platform. It uses token-based QR codes, permission-based access across four roles, and PostgreSQL Row-Level Security to block direct database reads.
For an inventory and point-of-sale system, I built a NestJS REST API with 57 endpoints and connected it to a React and TypeScript frontend. Its PostgreSQL transactions record sales, payments, and stock changes together.
I'm building Parcelles, an installable land-parcel management app for a family’s plots in the DRC. It includes a boundary editor, database-enforced user roles, and automated tests.
For my final-year project, I simulated water-network leak scenarios and trained a detector that caught 69 of 70 test leaks with zero false confirmations. I also founded and ran KALUX Enterprise, handling operations, customers, payments, and expenses while completing my degree.
