At Rubikas, I develop a Next.js vehicle-tracking dashboard and a standalone contact-management product, while taking end-to-end technical responsibility for web and mobile applications. I also maintain offline ERP and Customer Portal workflows with queued writes, retry and reconciliation.

At Combiine Limited, I was Lead Developer for the React Native stack and supporting services, helping rebuild the app and deliver four modular, multilingual iOS and Android products. I also worked on security remediation, offline behaviour and a sensor-based journey-tracking SDK integration.
