Website development_
MTECHNIC is a workshop in Obrenovac, Serbia, that tunes, codes and repairs the electronics of BMW and other cars, and processes ECU files for other workshops. We replaced a slow slider site with a fast one built around services, a quote from the vehicle and a File service for the trade.

The challenge_
The old website opened with a 600 KB slider image that needed 13.5 seconds to appear on a phone, its mobile hero was broken, and nobody could tell which calls and enquiries came from the site.
MTECHNIC needed pages that explain each service in plain words, take an enquiry or an ECU file in two steps, and open quickly on a phone.
Before and after_
A slider with a heavy image, and a hero that broke on phones.
A still hero that appears at once, the services in view and a quote from the vehicle.
The same slider banner on top, with the service text further down.
Symptoms, steps, FAQ and a direct way to ask, on desktop and on a phone.
What we did_
01_
Eleven service pages, from chiptuning and ECU options to key programming and airbag reset. Each one starts with the symptoms a driver recognises, then the steps, an FAQ and a price on request. Structured data, a sitemap and a social image for every page help search engines and AI assistants understand the workshop.
02_
A dedicated page for other workshops: upload the ECU file (.bin), choose the options and get the processed file back, usually within 2 to 12 hours. Both sides receive a tidy confirmation e-mail, and spam is stopped without puzzles for real customers.
03_
Brand, model and engine are picked first, so the enquiry reaches the workshop on WhatsApp or by phone with the car already described. Call, WhatsApp and form clicks are tracked, and a thank-you page confirms every enquiry.
04_
Images are WebP, the heavy slider is gone and forms load only when they come into view. Analytics starts only after a visitor agrees, and the pages are checked against WCAG 2.2 AA with an accessibility statement and privacy texts in Serbian.
Inside the site_
