Haynes Lab Avis 15

Haynes Lab was perfect for getting our MVP from 0 to 1. Through the whole process, Dan communicated with us exactly why he was designing our software in certain ways with pros and cons of the architecture. Look forward to working with him in the future!

Dan is very personable, and knowledgeable when it comes to building a brand! I have known him for years and he is very professional and outgoing.

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.

Working with Dan at Haynes Lab was a great experience for our store project. With Dan’s technical expertise and clear communication, we were able to create a really meaningful solution. Dan is thorough and very personable. He is someone I will definitely use in the future

I worked with Dan for a few months after dealing with a ton of issues from using some offshore devs, and the difference was night and day. He quickly fixed a lot of messy code, pointed out security issues we didn’t even realize were there, and helped us decide on what actually needed fixing vs what could wait. Dan was straightforward and easy to work with and he clearly cared about getting things right.

Totally amazing experience. Super thorough, capable, knowledgeable and patient.

Daniel was fantastic to work with from start to finish. He quickly dissected and truly understood my idea, then turned it into a polished, working web app with a clear and thoughtful approach. Communication was always excellent, timely, detailed, and easy to follow. He did a great job demoing progress and making sure each milestone was fully completed and validated before moving forward.

Since this project, I’ve rehired Daniel for other work and he’s become the first person I think of anytime I need dev work built or improved. Dan can jump in at any stage of your project and make an impact. He’s also the only developer I feel confident recommending to others, reliable, sharp, and genuinely invested in getting things done the right way.

Daniel is always willing to jump in and help with questions or extra details, and make sure everything is set up correctly from day one. I’m extremely happy with the outcome and will absolutely continue working with him on future projects. Highly recommend. If you have the opportunity to work with Daniel, take it. You won’t regret it.

I worked with Haynes Lab while building an early-stage product, and they were a genuinely solid partner throughout the process. The team has strong technical judgment, communicates clearly, and moves fast without cutting corners. Dan was hands-on when it mattered and helped us make practical decisions instead of overengineering things. It felt less like hiring a contractor and more like working with an extension of our own team that actually cared about shipping something real.
