Portrait of Pascal KasongaThoughtful engineering. Useful products.

01 / Portfolio

Selected Work.

Products and systems I've built across mobile, web, fintech, education, IoT, and data.

Parking session lifecycle

A traceable path from entry to exit.

Process overview

IoT / Smart Parking / NFC

Acoriss Smart Parking

NFC parking management connecting mobile operators, backend services, payments, and physical gate access.

Problem
Manual parking records made vehicle entry, payment control, and exits difficult to monitor. The system needed a traceable lifecycle for each vehicle while working with existing barriers.
Role
Full-Stack & Mobile Engineer / System Architect
Approach
A parking session starts with an NFC card scan, captures vehicle details, calculates a fee, records cash payment, grants temporary exit authorization, and closes after an exit scan opens the barrier.

04 / About

Engineering beyond the code.

I turn business requirements into reliable digital products — from architecture and APIs to mobile and web interfaces.

I care about maintainability, performance, and the details of a user experience. Good engineering makes a product easier to use today and easier to evolve tomorrow.
