Genuine client reviews

Has been a pleasure working with Mike. He did a fantastic job combining high-quality design with strong front end development (which I understand is rare), and has nicely balanced meeting our (detailed and frequent) requests with ideas of his own. Would strongly recommend him to anyone wanting to work with him.

Chris Wells

Mike was a pleasure to work with and did an exceptional job on our entire redesign. I’d highly recommend him to anybody who would like a modern and aesthetically pleasing website.

Andrew James

Mike was extremely creative and did a very thorough job of understanding our product and market before building a website that matched our needs and mission. He was very flexible with changes that came up throughout the process and does an awesome job of creating web animations (pulsing nodes, moving components, etc.) that added vibrancy to the website. All in all, very creative, patient, and great execution!

Borna Poursheikhani

Mike is a talented developer and designer that went above and beyond for our recent website project. He’s very easy to work with and always came up with solutions – nothing was too hard for him. I can’t recommend him enough!

Margo Camus

Mike did a great job on our HubSpot site. He worked to a tight schedule, interpreted the design brief we gave him really well and came up with a compelling design. He then delivered the finished product to schedule, working quickly to make any requested amends and add/change functionality. Really impressive work and Mike would certainly be my first choice for any similar work in the future.

Tom Byford

It was a pleasure to work with Mike on our music conference website. He went beyond what we needed him to do in order to create a beautiful new website which meets all our needs. We would definitely work with him on future projects.


I have worked with many developers and hands down the best! Quality of work is impeccable, everything went smooth and was easy to communicate with. I have project #2 ready for him to start.


Mike delivered exceptionally high-quality work. The design conveys the brand message and there were very few errors in the final platform. Despite several challenges outside their control, Mike was able to deliver within the condensed timeline.
