At PRE9ICT, I co-founded an IT consultancy delivering software for telecom, CRM, healthcare, and business workflow platforms. I’m responsible for architecture, development, technical decisions, and delivery across client projects.

At Bredband2, I developed and maintained business-critical CRM and customer-facing platforms, including Ruby on Rails and GraphQL services supporting sales and customer-management workflows. I’ve also contributed to platform integrations and customer-data migrations through telecom mergers, maintaining live customer systems without disruption.
