Things I’ve actually built.

A focused selection of work that represents what I’m building: a production access-management tool, a Master’s pathfinding project, and this site as a small full-stack playground.

Internal access tool

Infrabel · productionScope: Angular features, API work, access-flow fixes

An internal access-management tool at Belgium’s railway infrastructure manager. It handles delegated access flows around Active Directory and cloud identity. My contribution is mainly on Angular features, ASP.NET Core API work, and fixes around access-flow behaviour.

Angular feature work on a large internal front-end
ASP.NET Core API work with EF / MySQL
Active Directory integration through LDAP
Cloud identity changes routed through dedicated runners

Clean A* router

UMONS × Infrabel · 2025-26Scope: algorithm cleanup, cost model, benchmarks

My first-year Master’s internship focused on a cleaner railway itinerary router around A*. The goal was to make the behaviour easier to reason about: clearer cost handling, a reverse-Dijkstra heuristic, and benchmarkable results instead of relying only on intuition.

Reverse-Dijkstra heuristic over rail-distance data
Cost handling around junctions and front changes
Benchmarks on realistic railway scenarios
Compared against legacy behaviour route by route

iamhakim.comScope: personal end-to-end build

The page you’re on. It is still a portfolio, but built like a small product surface: real endpoints, persisted counters, a SignalR live channel, booking flow, and an A* visualiser running in the browser.
