Services
I can take a product from an idea, an existing system, or a stalled codebase and move it toward a clear, tested, production-ready release.

What I build
I work across the product lifecycle: concept, architecture, interface, backend, testing and deployment.
Multi-tenant platforms, roles, workflows, billing and data models built around real operations.
Local and cloud AI, intelligent tutors, 3D pipelines and interfaces beyond standard forms.
Smart home, MQTT, ESPHome, sensors and self-hosted systems connecting software to physical devices.
Responsive UI, i18n, security, testing, CI/CD, observability and modern deployment.
Secondary work
Physical prototypes and engineering experiments remain available in a separate space without competing with the core software portfolio.
About
I’m Redion Çekrezi. After more than 15 years of hands-on work with electronics, television systems, CCTV and technical equipment, I expanded that experience into software development. Today I build web products end to end—from discovery and architecture to UI, backend, testing and deployment.
Available for freelance projects, MVPs, SaaS platforms and business automation.
