Independent e-commerce developer
I'm Emre Ucak, an independent e-commerce developer since 2019. I work on PrestaShop, WooCommerce and Shopify, as well as custom development in PHP, Laravel and Node.js. Whether your shop is down or you're planning a project, you speak directly to the person writing the code.

Depending on your situation
-
Your shop is down
Payment failing, site unreachable, a 500 error after an update: I look at the code and the logs to understand what's broken, without a padded quote before I've even made a diagnosis.
-
You're planning a project
Migration, redesign, ERP or carrier integration, an internal tool: we scope the need before writing a line of code, with the boundaries set out in writing.
-
ChatGPT Ads conversion tracking
ChatGPT ads are now live in France: send real sales back through the OpenAI pixel and the Conversions API, while respecting consent.
The first exchange
-
You describe the problem
By email or phone: symptoms, available access, whether it's genuinely urgent.
-
I look before I quote
Access to the admin, server or code repository when needed, to avoid a quote built on guesswork.
-
You get a written brief
What will be done, what won't be, and a price range — not a number pulled out of thin air.
Frequently asked questions
