about

Pragmatic engineering, from legacy to AI.

Most of the world’s critical software is legacy: ERPs, government portals, core banking, telecom platforms. My job is to keep those systems alive and evolve them — without a full rewrite and without stopping the operation.

I’ve done this across public sector, energy, banking, telecom and mobility: workflow-heavy architectures, SAP integrations and legacy CMS platforms turned sustainable, observable, and ready to integrate AI — local or in the cloud.
