Haynes LabReviews of hayneslab.dev

Dan is an absolute dream developer to work with. I've worked with many over the years and Dan has been one of the very best. He stepped into a project that was at risk of going off the rails and completely turned it around in two days. His communication is excellent. He's thorough. He works efficiently. He understands what needs to be done and he gets it done. Couldn't ask for a better experience. I highly recommend Dan and Haynes Lab and will definitely hire him again.

I came to Haynes Lab with a rough idea and a tight timeline, and they delivered beyond expectations. Within weeks, we had a polished, production-ready MVP that didn’t just work - it impressed. Our first investor demo went better than I could have hoped, and I credit a lot of that to the quality of what the team built. They clearly understand the startup world; they move fast without cutting corners. If you’re a founder who needs technical muscle without the overhead of a full dev team, Haynes Lab is the call to make.

We started working with Dan not long ago and his knowledge and expertise has already improved the business. Super smart, very thorough and a pleasure to work with. We highly recommend him.

Haynes Lab has been an exceptional technology partner for McLean Corp USA. From our very first conversation, Dan took the time to understand our business, our priorities, and the specific outcomes we needed, then translated that into a clear and actionable technical plan. Dan combines deep technical expertise with a rare ability to explain complex concepts in straightforward, business friendly language. He helped us make smart decisions about architecture, tools, and integrations so that what we built not only works today but will scale with our growth in the future. Beyond the core build, Haynes Lab has effectively been our fractional CTO, giving us strategic guidance, helping us think through tradeoffs, and ensuring that technology is an accelerator not a bottleneck for McLean Corp USA. I highly recommend Haynes Lab to any business that wants a trusted, senior level engineering partner who can move fast without sacrificing quality. Dan has had a very positive impact on our technology stack and, ultimately, on our business results.

I’ve known Dan for years now and have watched and experienced his work ethic, drive, and commitment to excellence take place in many different forms. He is always a joy to work with and I feel in such great hands with him!

After working with several developers over the years, I can confidently say Dan stands out. He stepped into a codebase that wasn’t his, got up to speed incredibly fast, and was already making meaningful enhancements within hours. He found major security gaps in the code and fixed them, all in the first day. Dan’s communication is beyond excellent. He’s highly skilled, thorough, and most importantly, he’s honest and kind. He works quickly and efficiently. If you’re looking for someone who can integrate quickly and add value right away, Dan is the real deal. I’m honored to be working alongside him!

Dan does in a day what would take most people 4 days. It's pretty wild how good he is.

Dan communicates well by answering questions in a timely manner. He is knowledgeable and sees the big picture of my project. He was able to get the job done with minimal bugs and rework.
