“David is a great developer and very easy to work with. Communication is excellent and even though this project didn't have a hard deadline was completed quickly. David also provided several suggestions for improving the plugin in the future which we greatly appreciated. One of the best experiences we've had with a developer and we've worked with many. Looking forward to working with him on future projects”

“David is one of the most talented and fast web developers I've ever had the pleasure of working with. He is always responsive in a timely manner and his edits are always spot on with what we're asking.”

“Working with David is just great. Understands easily the assignment, delivers quality projects, makes pro-active suggestions and is definitely willing to go the extra mile. The cost-benefit ratio given his vast experience and quality of work is probably one of the best in the platform for webdev”

“David, I wanted to express my gratitude for the excellent work you've done on the golf tournament website; the design is sleek, user-friendly, and seamlessly integrates all the key event details, and your communication throughout the process has been outstanding, making me feel confident in the ongoing support you’ll provide moving forward. I truly appreciate your dedication and the thoughtful approach you’ve taken in creating such an intuitive and professional site.”

“David was such a pleasure to work with. From our first video chat, when I was just trying to determine if it was a good fit, he was pleasant, knowledgeable, patient with all my questions, not pushy with trying to get a sale, and explained everything he expected to accomplish. As we worked on the re-design, he was prompt, and had excellent feedback for me about certain processes or designs. Now that the website is complete, I am completely impressed and just thrilled that I chose to work with David. I would highly recommend David and will be working with him again for all of my website needs. Thank you David!! A+++”

“If you want an honest developer, who’s gonna price things fairly, does a great job with exceptional communication, this is the guy you go with. I spent almost 3 months interviewing so many other people for my project that either didn’t understand the scope or quoted me far more than they should have. Along with just various other problems.. David is an absolute rockstar once you come across this page don’t look anywhere else. Worth every penny spent.”

“There is a before and after David Ollenberger came into my life. Through his skills, knowledge, kindness and unique genuine personality he changed the view I had of the world and what was actually possible to do! I started it, but I’d like to say that we at the end of the day, together built a multi million project which has helped thousands around the world. Absolute recommendation to work with David in your business endeavour’s.”

“David has literally helped us go from a start-up to a near $1 million dollar company. David is one of the strongest developers I’ve worked with – we’ve rarely had a challenge that he could not solve and solve quickly. I’d recommend him in the strongest possible way to any company fortunate enough to be considering them. Thanks for the great work, David, and for helping us build a great product and a successful business!”

“Working with David is a great pleasure. He has the world-class project management skills and technical know-how of a 10x developer, which is a game changer. His reliability and professionalism have been a blessing compared to previous developer hires. Beyond the heavy lifting he’s done as a developer, his spirit of kindness and hospitality never ceases to amaze me. Even when presented with the most complex challenges, from a client’s perspective, he makes the work appear effortless.”

“When I interviewed David about the job I told him that I had had very bad experience with 6 others who tried to do the job and just bailed on me – he told me to trust him so I took a chance on him, and I’m glad I did. David did not only do what 6 others here on Upwork couldn’t do but he also did it SO much better than the other attempts – he never gave up and designed what was needed to do the job right. I highly recommend David to anyone who needs work done – this guy delivers!!”
