Nathan is a gifted animator and artist. We came to him with a short animation project and he gave us a very clean professionally produced clip. He followed our instructions carefully and made positive suggestions that added value beyond our initial instructions. Most of all, he was reliable and delivered on his commitments in a timely manner. I would highly recommend Nathan for animation projects.
Chris Vervaeke's Review Sourced from Google
We've been very satisfied with Nathan's delivery every time we've used his services. Most recently he rebuilt our website to improve our SEO and created some new animations for us. His communication was excellent and the final product was right in line with what we were looking for. I wouldn't hesitate to recommend his services, you'd be in good hands.

Greg Crossan's Review Sourced from Google
I hired Phoenix Afterglow to help me create a sales page and a digital marketing strategy to drive more traffic to the site. Johnny was great to work with. His process was easy and it helped create clarity and focus for my business and marketing. I also have a repeatable process for content creation and to continuously drive traffic to my site. Most importantly, Johnny was willing to work within my budget. I have already started seeing improvements and will continue to work with him in the future. If you are looking for a web developer that can do it all, I highly recommend Johnny and the Phoenix Afterglow team.
Patti Anastasia's Review Sourced from Google
Absolutely incredible! I’ve always struggled to even explain what I need, constantly worrying that something was outdated, broken, or not in compliance—and don’t even get me started on generating leads and turning them into paying clients! There are just so many little things that can go wrong… but not anymore!If you’re anything like me—and even if you had the time to handle all of this, but don’t want to—you need to contact Phoenix Afterglow. They’ll help your business Rise Up!Huge thanks to Johnny for your amazing support, kind words, and for identifying issues I didn’t even know existed. You’re the best, and I’m truly grateful. I now feel confident knowing my website—and everything tied to it—is in the right hands.

Software Development Review from Vladyslav Sorochan
A true tech partner who just gets it! Aqe has brought our rough software concept to life and turned it into a smart platform. The project covered everything from custom development to AI features and some pretty advanced data engineering. From the beginning, their team really took the time to understand what we were trying to achieve. They started with a clear discovery phase and built a solution that checked all the boxes in terms of functionality and ease of use.It is easy to work with their team, not only in terms of technical skills but also in how responsive and collaborative they are. They regularly improved features based on our feedback as we moved along and were always available when we needed support, even after the post-launch. Having that kind of ongoing help made a big difference.The results were a bit better than we expected. We saw a noticeable drop in manual work, smoother internal operations, and improved decision-making through real-time data.Overall, Aqe and their team really delivered what they promised, on time and within our budget. The whole experience was smooth, professional, and well-managed. Wed happily recommend working with them.
