About Albert

Met meer dan 15 jaar ervaring in PHP-ontwikkeling help ik bedrijven met het bouwen van snelle, veilige en goed onderhoudbare webapplicaties. Mijn specialisaties zijn Laravel, WordPress en systeemarchitectuur.


Ik heb bewezen resultaten geboekt: bij De Streekboer reduceerde ik de verwerkingstijd van logistieke processen met 70% door een op maat gebouwd Yii2-systeem. Bij EveryOffice leidde ik de volledige migratie naar Laravel en PHP 8.x, inclusief Dockerisering van de productieomgeving. En bij MKB verbeterde ik Core Web Vitals scores met 40% door WordPress-installaties te optimaliseren en afhankelijkheid van third-party plugins te elimineren.


Ik werk volledig remote, ben gewend aan asynchroon samenwerken en lever schone, gedocumenteerde code op. Of het nu gaat om een complex Laravel-project, WordPress-maatwerk, API-integraties of het opruimen van technische schuld, ik pak het resultaatgericht aan.


Beschikbaar voor zowel kortlopende opdrachten als langetermijn samenwerking.
