Chop Dawg Reviews & Testimonials

Web Development Review from Jimmy Caldwell
Chop Dawg was the strongest development team I’ve worked with in 18 years of software implementation. They took our complex AI-powered senior placement platform and turned it into a functional marketplace with dashboards, business rules, CRM integration, and an AI assistant. The team listened, adapted, communicated often, and treated our vision with real care. The handoff had a few gaps, but overall, they delivered exceptional work.

Design Services Review from Nathan May
Chop Dawg delivered wireframes, high-fidelity screens, a logo, and Figma files while keeping each week’s work clear. They felt like part of our team, brought fresh ideas, and pushed back when needed. The experience was strong overall, though a more detailed final review would have been helpful.

Web Design Review from Anonymous
Chop Dawg turned our early idea for a visual polling and decision-making platform into a prototype we could confidently share with others. It made the product much easier to explain, gave us something real to test with users, and supported more productive investor conversations. The work also helped our team get aligned on the product direction, development scope, and MVP roadmap. Their team was responsive, organized, and easy to work with throughout the process.

SoftDoes Reviews & Testimonials
Yuliia Ten's Review Sourced from Google
I started working with SoftDoes when our product had already grown beyond the point where small fixes were enough. We needed to rethink several parts of the system and make sure the next stage of growth would not create even more technical debt.The team got into the project fast. Within the first few weeks, they helped us identify the main bottlenecks, clean up several fragile integrations, and improve the parts of the platform that were slowing us down the most.One practical result was that a key operation that used to take around 4-5 minutes now takes less than a minute. I also saw a noticeable drop in recurring technical issues after the release.What I liked most was the way they worked with us. Very little ceremony, clear communication, good technical judgment, and a strong sense of ownership.I’d be happy to work with SoftDoes again on another complex software project.
Ryder Mackey's Review Sourced from Google
My experience with SoftDoes has been extremely disappointing. Their communication is terrible, the people I dealt with were highly unprofessional, and their pricing is absolutely outrageous compared to the value of the work being delivered.One of my biggest concerns is the company’s lack of transparency. From what I’ve observed, their development work appears to be outsourced to people in Ukraine through another company called Come Back Agency. Even when I searched for SoftDoes online, its website appeared to redirect to Come Back Agency.Take a look at their LinkedIn yourself. They present themselves as a Kansas City-based company, yet I couldn’t find a single employee listed as being based in Kansas City. That raises serious questions about their business structure, where their team actually operates, and who you’re really paying to develop your software.My interactions with the CEO, Orest, were particularly unpleasant. I found him extremely arrogant, dismissive, and condescending. He speaks to customers as though they’re beneath him. Rather than addressing legitimate concerns professionally, his attitude made an already frustrating experience even worse.Their Google reviews also raised serious red flags for me. Several reviewer profiles appeared to have AI-generated profile pictures, and the reviews themselves read as though they were written by ChatGPT rather than genuine customers. Many of these accounts had only ever reviewed SoftDoes.After I confronted them about these concerns, I noticed that some profile pictures had been changed to what appeared to be stock images, and the accounts had gained an additional review of random places. I cannot independently verify who operates these accounts, but the timing and patterns made me seriously question the authenticity of their online reputation.Nothing about my experience with SoftDoes has inspired trust. If you’re looking for custom software development, do yourself a favor and look elsewhere. Verify who you’re actually doing business with, who will be developing your software, and what you’re paying for.
Kevin Parker's Review Sourced from Google
We had been running a large part of our business through spreadsheets and a mix of different tools for years. We've grown past spreadsheets now. SoftDoes built a custom platform around the way our team actually works. That's probably what we appreciated most about working with them.

I had a very informative meeting with Cesar. He was very professional and provided a lot of details on their services. I will be including them in my marketing process.
Brandon Howard (Sin City Parties)'s Review Sourced from Google
Ana, Jose, or Cesar are the best! They totally transformed my business website. I trust them completely and the results are incredible. Our website has never looked better. If you ever need help with anything, they’re your guys. They’re quick and responsive, and they’ll get you the answers and website you need. I would recommend them to everyone.

cameron's Review Sourced from Google
Finding a truly skilled app developer Bellingham can be incredibly difficult, but the team at nsite.tech completely shattered our expectations. We needed a complex platform built that required flawless functionality on both iOS and Android, and they delivered exactly what we were looking for.What sets them apart from other tech agencies is their deep understanding of app optimization, API integrations, and user experience. They didn't just write clean code; they took the time to understand our business goals to ensure our app would scale smoothly as our user base grows.If you are a business owner or startup founder looking for an experienced, reliable, and highly communicative app developer in Bellingham, look no further than nsite.tech. They make the development process painless and deliver a premium end product. Highly recommended!
kevin taff's Review Sourced from Google
I cannot say enough good things about the team at nsite.tech. When we first started looking for a Bellingham web designer, we didn't realize how much we also needed a true technical partner who understood the backend architecture of software. They didn't just build us a pretty website—they essentially acted as our custom app developer in Bellingham, creating a completely tailored customer portal that seamlessly syncs with our inventory.The launch was incredibly smooth, our page loading speeds have drastically improved, and our local search visibility is already climbing. They are responsive, highly skilled, and transparent about costs. If you need a premium digital presence, this is the team you hire.
Riley Kennemer's Review Sourced from Google
If you need a platform built smoothly, professionally and correctly, you give these guys a call. Bottomline is they do great work in a timely fashion. Highly recommend.
