01Selected work
Each project shows a different side of my work — from architecture and business logic to visual experience and hardware–software integration.
Multi-tenant field operations
A complete SaaS operations platform for field-service companies. It centralizes projects, job sites, employees, equipment, inventory, documents, working hours and daily reports while connecting office and field teams.
5 years of hands-on tree-care experience
Direct field knowledge translated into digital, automated workflows.
Restaurant software
Restaurant software where the table QR menu in four languages, Service Radar, POS, kitchen display, online ordering and the venue website run on one core. Each venue decides how much of it to switch on.
Multi-Tenant SaaS & White-Label Platform
A SaaS platform for creating and operating branded business websites with tenant-isolated administration, subscriptions, custom domains and controlled AI-assisted workflows.
AI software factory
An adaptive AI software factory: governed stations do the work and AI models are replaceable workers. Every step passes quality gates and leaves replayable evidence. One request goes in, a verified, runnable app comes out.
Local-first personal AI runtime
A portable personal AI runtime with one persistent identity, one governed memory system and authorized capability providers across bodies, devices and services.
Smart piano learning & playback system
A local-first smart piano appliance that connects to a digital piano over USB-MIDI and turns it into a modern learning, playback and practice system.
Multi-tenant editorial control plane
From source to approved content: one story, independent website, Facebook and Instagram variants, and traceable human approvals, with AI kept inside clear boundaries.
Automotive workshop SaaS
A multi-tenant operations platform combining customers, vehicles, services, inventory, appointments, teams and invoicing in one focused workspace for automotive workshops.
More Projects
Website checks with understandable proposals and a saved history
Findbar checks a website, groups confirmed findings and proposes exact changes. Profiles retain evidence, review decisions and history. A real FlowGastronomie correction cycle is documented.
Spatial 360° interface
A spatial interface for rooms, content and connected objects: explore in 360°, select an object, edit it in context and share it deliberately as a showroom.
Explainable job matching
A personal workspace for jobs and freelance work: reviewed profile data becomes explainable matches and editable application drafts. Nothing is sent to employers automatically.
Local-first business software
A focused application for small construction and service businesses, connecting calculation, quotation, field execution and final invoicing in one clear workflow.
360° learning platform
A 360° demo room connects reading, activities and parent controls. The web app is in an approved-account Family Test; Android for Google Play is in preparation.
Business requests, in flow.
Small service teams receive requests across apps, then manually decide who should handle them and when. Relay gives each request a structured place and a clear next step.
02Public code
16 public repositories on GitHub with READMEs, screenshots, tests and CI. Demo data is fictitious.

Client websites
I build responsive, fast websites shaped around each business and its workflows — using CMS, automation and AI where they add concrete value.
03Capabilities
I work across the product lifecycle: concept, architecture, interface, backend, testing and deployment.
Secondary work
Physical prototypes and engineering experiments remain available in a separate space without competing with the core software portfolio.
04About
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 — most projects in this portfolio I conceived, built and operated independently; client projects are labeled as such. My current focus is software, AI and technical systems.
Open to a permanent role as a software developer (full-stack, automation, AI) in the Ruhr area or remote.
05Contact
Send me a short outline of the problem, users, and outcome you need. I can support the work from architecture and UI through backend, testing, and deployment.
