TechAvidus Reviews & Testimonials

Software Development Review from Marcos Queiroz
They were very responsive and the quality of the work was good. We experienced a few challenges with the back and forth during deliveries and some unexpected delays but they were always receptive to feedback and responded well to our concerns. I'd happily recommend them, especially Megha as the Project Manager and Savan as the Developer.

Software Development Review from Slava Berkovich
SapientPro consistently delivers high-quality work that aligns with project requirements. The team demonstrates strong expertise in Angular, TypeScript, and JavaScript. Their project management and communication practices are highly effective, with weekly client meetings held to provide updates on progress and ensure alignment.

Software Development Review from Jeremy Ott
This team was extremely responsive from the start. They pulled together a comprehensive quote for my MVP and have delivered on all of the requirements. The daily updates from the product/project manager are extremely helpful and it’s clear that the team cares about the quality of work they deliver. The engineers working on the product are always willing to make recommendations and go above and beyond to make the experience and underlying infrastructure that much better.

eCommerce Development Review from Luc Vlekken
We've had the pleasure of working closely with this development team on several projects, and the experience has been consistently excellent. Not only are they highly skilled developers, but they also think along with us both from a technical and a product/customer perspective. Their proactive attitude, reliability, and ability to translate complex requirements into elegant solutions make them a true partner rather than just a supplier. Highly recommended.

From the very beginning, Grawlix excelled in gathering our requirements, ensuring they thoroughly understood our unique needs and pain points. Their team was highly communicative, providing insightful recommendations that helped refine our vision. The development phase was marked by a seamless integration of our specifications into a user-friendly and efficient platform. Grawlixs attention to detail was evident in every aspect, from the intuitive design to the robust functionality of the software. As we moved towards the launch, their support was unwavering, addressing any last-minute adjustments with professionalism and speed. The final product exceeded our expectations, streamlining our staffing processes and enhancing overall efficiency.

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.

CodingCops Reviews & Testimonials
kathi Richard's Review Sourced from Google
We had this cool idea to create adaptive learning paths for our students based on their quiz performance and interaction patterns. But building the logic was beyond our team’s expertise. CodingCops helped us hire AI developers who designed a lightweight recommendation model that personalized learning modules dynamically. It made our platform way more engaging for students.
Ashley Kai's Review Sourced from Google
CodingCops has some of the best engineers out there. We brought on a QA Automation Engineer through them, and he turned out to be the best we’ve worked with after trying several contractors before. Super skilled, technically sharp, and he really took ownership of QA. He felt like part of our team from day one, not an outsider. We’ll definitely be going back to CodingCops again, not just for this role but for others too.
Rachel Willy's Review Sourced from Google
They’ve done an excellent job connecting me with a skilled developer. They’ve also been very responsive in addressing any issues along the way. I’m extremely satisfied with both the service CodingCops provides and the developer I’ve had the chance to work with.
