"I recently worked with Dean to build a booking and scheduling app, and I honestly couldn't be happier with the experience. Communication was smooth and consistent — he kept me in the loop at every stage. What really impressed me was how quickly everything came together without any drop in quality. Dean clearly knew what he was doing, but more than that, he genuinely cared about getting it right for me. There were moments where Dean went above and beyond what I expected — suggesting improvements I hadn't even thought of. I'll definitely be working with him again."

"I highly recommend Dean for any mobile app development or app troubleshooting needs. I hired him to fix and rebuild my application, and the results have been incredible. Dean demonstrated deep technical expertise in full-stack app development, quickly identifying the root causes of my app's performance issues and implementing a robust, scalable rebuild. He was professional, transparent about timelines, and maintained excellent communication throughout. His work has significantly improved my app's functionality and user experience."

"Working with Dean to create bellaflorjewellery was a fantastic experience. I had a specific vision for how I wanted my jewellery pieces to be displayed, and Dean brought that vision to life perfectly. Dean was incredibly patient with my requests and provided great technical advice throughout the process to ensure the site was fast and easy for my customers to navigate. I'm thrilled with the end result — the site looks beautiful and is already helping me grow my business. I couldn't have asked for a better partner for this project!"

Plan, build, launch

Proper websites and apps start with a clear business conversation.

Before a build starts, the goal is mapped around the customer journey, content, conversion points, and the simplest version that can ship well.

FAQ

Questions before you get in touch.

How much does a website or app cost?

Websites start from £249, simple tools from £399, and working web apps from £699. Every project gets a fixed price and scope agreed up front — see the pricing page for a full breakdown.

How long does a project take?

Most website builds take 1–3 weeks. Focused tools can take 3–7 days, and many properly scoped starter web apps launch in 1–2 weeks. Larger platforms take longer depending on integrations and complexity.

Do you work with businesses outside London?

Yes. Dean Da Dev is based in Stratford, London E15 but works remotely with businesses across the whole UK — location is never a barrier to starting a project.

What happens on a discovery call?

It's a short, no-obligation conversation about what you're trying to build, your budget, and your timeline. You'll leave with a clear next step, whether that's a quote or just some honest advice.

Do I own the finished website, app, or tool?

Yes. Once a project is paid for, the code, design, and any accounts set up for it belong to you.
