WooCommerce Review from Amanda Viviano

We hired Qolos to build our local florist shop's website on WordPress and WooCommerce, and we couldn't be happier with the results. From the start, they took the time to understand our business and created a site that's not only beautiful but easy for our customers to browse and shop. The WooCommerce setup was seamless, our online ordering works exactly the way we needed it to. But what really sets Qolos apart is their ongoing monthly maintenance. We never have to worry about updates, security, or technical issues because they stay on top of everything. Any time we've had a question or a small change request, they've been responsive and professional. As a small local business, it means a lot to work with a team that genuinely cares about keeping our site running smoothly. Qolos has been a true partner, not just a vendor. Highly recommend them to any local business looking for reliable web design and maintenance!

Web Development Review from Sanjay Singh

I kept getting negative reviews about my app for technical glitches, heating issues, functionality, loading time, crashing, and more bugs. So, I reached out to QOLOS after going through 2-3 renowned review platforms. I explained my app issue to the team, and they did tremendous work with their mobile testing solutions. Also, I wanted to build a website for my app. They created a feature-rich and seamless website.

Staff Augmentation Review from Sergey Novik

Were developing an internal image processing tool for our design team and needed two machine learning engineers, since our core developers were busy with other client projects. We required extra hands familiar with Python and computer vision, so after a developers market review, we hired them from SumatoSoft. The SumatoSoft developers joined our team and were able to swiftly adapt to our workflows, which resulted in them delivering the working models well before our hard deadline. Communication was straightforward throughout the engagement. We had video calls and exchanged brief text updates on a weekly basis. The delivered code is clean, and pull requests are well-documented. I appreciate that they pushed back on a few of our initial architecture ideas. They challenged our original approach and proposed a better method for handling the model weights. We plan to bring them back for the next phase of development.

Acropolium took full ownership of complex technical components and worked as a seamless extension of our internal team from day one.

Mobile App Development Review from Guiulianna Cespedes

Our company needed an Android app that could support a mental health platform in a way that felt calm, easy to use, and dependable for daily users. We hired Simpalm to build that product in Kotlin and help us move from concept into something real customers could use. For us, trust and simplicity mattered more than packing in too many features. They took a fairly hands-on role, which was helpful because we were still making product decisions as the project moved. Some weeks I was deeply involved reviewing screens, and other weeks they pushed things forward on their own. That balance worked well. They would usually come back with two or three options instead of just asking what we wanted. We did hit one rough patch around notifications where the first version didn’t behave the way we expected, so that had to be revisited. They fixed it without making the process difficult. The finished app runs smoothly, feels organized, and gave us a much stronger mobile presence on Android. Most importantly, early users found it approachable rather than overwhelming, which was exactly what we wanted.

Mobile App Development Review from Amanda Chalofsky

My experience with Simpalm was very good. They made a full prototype of our neuro-wellness app so we could show partners and investors what our system looks like. It matched our brand and showed the flow in a simple way. Their communication was steady, they stayed on time, and they explained things clearly. The prototype helped people understand our idea fast, and it moved our project forward. I felt supported the whole time.

They were flexible when we added new features, and their designer’s input really helped improve the look and usability of the app. I appreciated how reliable and easy they were to work with having a U.S.-based team made communication smooth and fast.

We worked with Techstack to develop a digital platform that could support the financial and operational needs of our growing client base. Our vision was to create an integrated web solution that would bring together financial management, client communication, and digital infrastructure into one cohesive system.

Techstack company quickly understood what we were trying to achieve. They built a modern web application architecture that unified financial analytics, project tracking, and CRM capabilities while ensuring top performance and security.

Web Development Review from Sri Sharma

When we brought Techstack on board, our analytics subsystem was at a breaking point. Performance issues, data inconsistencies, and outdated architecture were slowing us down and creating friction for both our internal teams and end users. Given the scale of our platform: millions of customer interactions generating terabytes of data daily we needed a partner who could not only fix the flaws but also future-proof the entire system. Techstack company took on the challenge with impressive precision. Their team started with a deep audit that revealed critical weaknesses in our existing infrastructure. From there, they restructured the backend, optimized performance, and built a reliable synchronization flow between our internal tools and third-party CRMs. Techstack introduced a new architecture powered by Amazon Redshift and an asynchronous analytics engine, which dramatically reduced data retrieval times and improved responsiveness across the board. What we appreciated most was how seamlessly they integrated into our process. They communicated clearly, delivered consistently, and made sure every change was fully tested and stable before rollout. The results were: system reliability improved, performance bottlenecks disappeared, and we could finally handle large-scale data processing without worrying about stability. Techstack company combined strong engineering skills with a genuine commitment to understanding our goals. They helped us rebuild confidence in our platforms ability to scale and perform at its best.

We hired Competenza to build a custom software tool to help manage our online bookings and product sales in one place. They designed and developed a booking system for our spa that also connected with our product store. It included custom dashboards, easy scheduling, and reports we could actually use.

They really listened to our needs and built something that felt like it was made just for us, not a one-size-fits-all. Everything was done on time and the process was smooth. Communication was clear, and they were quick to make changes when we asked.
