A few months ago I was talking to a store owner who had paid two different developers to fix the same checkout bug. Both times he was told it was done. Both times it came back within a week. By the time he found me he was not even frustrated anymore; just quietly exhausted, the kind of tired that comes from spending money on the same problem twice and still not knowing if the third time would be different. That conversation stayed with me because it it not a rare story. It is actually a very common one. And most of the time the developer who "fixed" it was not cutting corners on purpose, they just patched what they could see instead of finding what actually caused it. The bug disappears. Everyone is happy. Then it comes back when the client is in the middle of a product launch or a sale and the timing could not be worse. That is the thing I keep coming back to in this work. Not just does it look fixed today but will it still be fixed in two months when nobody is watching it. That one question changes how you approach almost everything; how long you spend on diagnosis before you touch anything, whether you tell a client what they want to hear or what is actually true, whether you patch the symptom or trace it back to the source even when that takes longer. I work in Shopify, WooCommerce, and PrestaShop. The technical side covers platform migrations, performance and Core Web Vitals work, theme builds and customization, bug fixes, app conflict resolution, and compliance setup; GDPR for stores selling into Europe, ADA and WCAG accessibility for US markets, proper policy pages and cookie consent that are actually implemented correctly instead of just copy-pasted from a template. I started in January 2024, spent about two years building and breaking things on my own before I took a single paying client, because I wanted to understand why things fail before I charged anyone to fix them. The other side of what I do is copy. eCommerce copy speciafically product descriptions, homepage and landing page content, email sequences, blog content for stores that need their words to do actual work. This grew out of the development work in a way that felt inevitable. You spend enough time inside stores that are technically solid but still not converting and you start to see very clearly that a fast clean store with bad copy is still a store with a problem. The two things are connected and treating them as separate jobs is part of why a lot of stores underperform even after the technical side gets fixed. Here is something worth knowing if you are evaluating developers right now, for this project or any other one. Ask to see the before and after. Not the claim, the documentation. A real Lighthouse audit with timestamps on performance work. An explanation of the actual root cause on a bug fix, not just confirmation that it looks okay now. A redirect map and post-launch Search Console data on a migration. If a developer cannot show you that or does not think it matters, that tells you something important about how they work before you find out the harder way. If something on your store is broken, slow, not converting the way it should, or you are planning a migration and want it done without losing three years of search rankings overnight, tell me about it. I will give you a straight read on what it actually needs, including if the honest answer is that it is smaller that you think or bigger than you were hoping.
