Real reviews from verified Fiverr clients
“Had a great experience with Devjour Tech. He built me a full website with lots of customized sections that required a professional web designer. It's tough these days to find people who can actually do what they say they can do. I am so happy I have found a developer that I know can confidently do the work that is needed. 5 stars!!”
“Great service and went above the required job! I wanted help with some specific coding and font adjustments, the coding has now allowed me to fully control the font sizing with an adjustment tool which is super helpful! Small issues with the website were also fixed. Would highly recommend if you are looking for a coding expert for your Shopify store!”
“We are very happy with the work delivered. He helped us solve several bugs and issues we had on our website and was extremely helpful throughout the entire process. Communication was always professional and efficient, and he paid great attention to detail while following all the guidelines we provided.”
“This is the second project we have worked on and I have been completely satisfied each time, the work was executed professionally and he did what he said he would do. Highly recommend.”

Full Stack Development questions
Can you take over an existing codebase?
Yes. We audit first, stabilize what's fragile, then improve incrementally, no big-bang rewrites unless the code genuinely demands it.
How do you handle projects from idea stage?
We start with a scoping phase: goals, user flows and an architecture proposal with fixed pricing per milestone, so you always know cost before commitment.
Who owns the code?
You do, fully. Clean repositories, documentation and handoff are part of every engagement.
