About Lars

Ik ben een software-ontwikkelaar met een focus op backend-automatisering en webbeveiliging. Bij mijn vorige werkgever, een ISP, bouwde ik automatiseringstools en een volledig security header analyseplatform — inclusief scoringslogica, API-ontwerp en deployment

Ik werk goed in situaties waar het probleem nog niet volledig gedefinieerd is. Geef me een workflow om te automatiseren, een API om te bouwen of een beveiligingsgat om te dichten, en ik los het op.

Momenteel studeer ik Business & IT aan de Universiteit Twente en ben ik beschikbaar voor korte en middellange projecten.
