Ondřej Nevřela – Full Stack developer focused on PHP, Vue, ERP, and AI

Ecuservis is a specialized website for repair and exchange requests of car control units. It's not a classic e-shop, but a system where the customer picks a service (repair or exchange) and then physically sends the part for evaluation and service. The site currently has over 20,000 products and is available in in four language versions.

The frontend is designed for this business type – focusing on clarity, conversion paths, and SEO optimization for different language markets.

• Backend: PHP (internal framework), Elasticsearch, Redis, MySQL
• Frontend: Latte templates, jQuery
• Reklamy a analytika: Google Ads (campaigns, imports), Google Analytics, Search Console
• SEO: adapted for different language versions and markets (CZ, SK, FR, ES)
• Administration: connection to public and internal Remante APIs (ERP, order processing, notifications)
• ERP integration: Pohoda, Helios

• Leading development and long-term maintenance of the entire system
• Implementing and improving a custom UX and frontend for this unique service
• Creating and managing Google Ads campaigns
• Developing and optimizing internal admin and automated processes
• Ongoing work on SEO, content, language versions, and improving conversion rate
• Creating and automating the entire order workflow from customer receipt to repair and shipping

• Four language versions with separate SEO and ad strategies
• Unusual business model requiring custom frontend logic and workflow
• High product volume with focus on precise filtering and categorization
• Connection to ERP systems, automation, and a custom ECU production module

The ECU production module is a key part of EcuServis's internal admin, developed to replace the inadequate TDIS system.

Unlike mass production, this system focuses on individual control unit repairs that need flexible workflows and advanced automation.

The module lets technicians record times, enter material usage, change order statuses, and generate documents and outputs for customers – including repair reports and ongoing order status tracking. The system actively helps decision-making with automated decision trees and predictive logic, increasing work efficiency and reducing errors.

• Backend: PHP (internal framework), Redis, MySQL
• Frontend: Latte templates, jQuery
• ERP integration: Pohoda, Helios (receipts, dispatch notes, transfers, orders)
• Data logic: decision trees, predictions based on history
• Statistics and analysis: charts for tracking repair performance, material, and technician workload

• Full design, development, and maintenance of the entire system (architecture and UX)
• Designing and optimizing workflows for technicians, inventory, and customer service
• Automating material orders and linking with suppliers
• Building and implementing connections to ERP systems
• Regularly developing new features based on real use and feedback

• Full integration with ERP systems – not just reading data but also actively creating documents
• Creates a unified knowledge database for repair procedures
• Extensive statistics: technician performance, consumption, repair success rate

Ecuexchange.cz is a B2C e-shop focused on direct sales of refurbished control units. Unlike ecuservis.eu, which works on request and repair, ecuexchange.com is designed as a classic shopping cart with instant ordering.

The site runs on a simplified architecture but uses the same internal framework I built for admin management. The admin is connected not only to the ERP system (Pohoda, Helios) but also to the ECU production module, from which it gets information about availability, repair status, or product history.

The site is available in multiple language versions and is planned to expand to other markets. The project also includes connection to various marketplaces and management of product feeds and ad campaigns.

• Backend: PHP (internal framework), Elasticsearch, Redis, MySQL
• Frontend: Latte templates, jQuery
• Connection to the ECU production module: via API
• Marketing & distribution: Google Ads, product feeds, marketplaces
• ERP integration: Pohoda, Helios

• Designing and developing the admin with the internal framework
• Connecting to ERP and the ECU production module
• Creating feeds and integrations for marketplaces
• Technical management of multilingual content and expanding to new markets
• Ongoing optimization and development according to business needs

• Direct connection between frontend, ERP, and production
• Clear B2C purchase process with potential for future expansion

Web app for client Fohet that lets users design their own solar solution for a family house directly on a map.

The user enters an address, selects a roof, marks the installation area, and picks panel type – the app then automatically calculates:

• expected power for each month,
• annual efficiency,
• return on investment and total cost.

Once the configuration is complete, the app generates a PDF output and saves the configuration in the system for further processing.

• Frontend: React
• API integration: European API for efficiency calculations (considering roof tilt, orientation, location)
• Outputs: PDF generation and saving the configuration for follow-up

• Initial development of the configurator frontend
• Implementing an interactive map and drawing the area on the roof
• Visualizing panels on the map based on chosen layout and type
• Connecting to the calculation API for efficiency and return simulations

• Real geographic and orientation data affecting calculation
• Interactive UI with direct visual feedback

In cooperation with Remante, I develop and maintain the developer framework for building admin panels and B2B systems, which serves as a unified base for over ten projects. The original jQuery-based system I gradually rewrote into a modern SPA application in Vue 3 with emphasis on component design, clean UX, and reusability.

This platform also includes the standalone shared library (shared library), which contains common functions, helper tools, data models, and API clients used across all Remante apps. The library ensures consistency, speeds up development, and simplifies change management in all systems.

• Frontend: Vue 3, Composition API, Tailwind CSS
• Shared library: JS/TS utilities, API clients, data validations, models
• Backend: PHP (with optimizations for internal needs)

• Developing and rewriting the framework from jQuery to Vue 3 SPA architecture
• Designing and creating Vue components (tables, forms, workflow, editors)
• Creating and maintaining the shared library across projects
• Ensuring compatibility, reusability, and maintenance across different systems
• Long-term optimization and development of the new generation of admin panels

• Significant speed-up of development across projects thanks to a unified base stack
• Big reduction in duplicate code and simplified refactoring
• Used both internally (admin panels, development tools) and externally (B2B portals)
