Currently building my own automotive diagnostic platform 🚗⚙️
Alongside developing the Trezzo ecosystem, I’ve also been working on a custom automotive diagnostics platform focused on real-time vehicle monitoring and diagnostic workflows.
The system is designed around:
• ECU communication
• Live vehicle telemetry
• Diagnostic trouble codes (DTC)
• System scanning
• Actuator testing
• Coding & service functions
• Hardware integration workflows
The goal is not just UI design, but building a scalable diagnostic environment that combines software architecture, realtime data processing, and automotive tooling into one ecosystem.
Still a work in progress, but it’s exciting to see the platform gradually evolve into a real diagnostic system.
Curious what people from automotive software or embedded systems think about this direction. 👨💻

Building Trezzo Marketplace 🚀
Trezzo is not a template-based project or a quick Playwright-generated demo.
It’s a growing ecosystem built from the ground up:
Marketplace, creator profiles, social feed, digital products, work layer, messaging, payments, affiliate systems, and more — all connected into one platform.
This screenshot shows a real part of the development workflow:
on the left, the actual Vue/Vite source code;
on the right, the live Marketplace running on trezzo.cz (http://trezzo.cz).
The goal is not just to create another website, but to build a scalable ecosystem where every layer works together as a unified product.
