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.

Working with QOLOS was the best decision I have made in regards to scaling my business. They are professional, so creative, they communicate every step of the way and their pricing is fair for the highest quality work. The designer of our logo and website did it well and I am so impressed and proud of the final product! the designer listened and knew exactly what I wanted which made the process so simple. Seriously could not recommend QOLOS more!

Software Development Review from Claus-Peter Mueller

We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork.The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages. At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.

Web Design Review from Anonymous

Thanks to Infinum's website refresh, the client has seen an almost 100% improvement in their website's conversion rates. The team excels at project management, using the client's own proprietary tool and also Figma very well. Their proficiency in design, delivery, and client relations stands out.

Mobile App Development Review from Robert Beknazarian

Working with Tepia Co has been an exceptional experience from start to finish. They played a critical role in developing our mobile app for RELI, and I can confidently say they exceeded our expectations on every levelFrom day one, Tepia demonstrated a deep understanding of both the technical and business sides of app development. They didnt just execute tasks they asked the right questions, challenged assumptions when needed, and helped us think through complex workflows in a way that improved the final product. Their team truly operates as a strategic partner, not just a development vendor The communication was excellent throughout the entire process. We always knew where things stood, timelines were clear, and any issues or changes were handled proactively and transparently. For a project as complex as ours involving pricing logic, user flows, financing options, compliance considerations, and scalability this level of clarity and responsiveness made a huge difference.What really stood out was Tepias attention to detail and commitment to quality. The app they helped build is stable, clean, intuitive, and built with long-term growth in mind. They were thoughtful about architecture, performance, and future enhancements, which is critical for a company like ours that plans to scale aggressively.They were also extremely flexible and patient as our requirements evolved (which happens in real-world startups). Instead of pushing back, they collaborated with us to find smart, efficient solutions that aligned with our vision and budget.If youre a founder or business owner looking for a team that:Truly understands mobile app developmentCommunicates clearly and consistentlyThinks strategically, not just technicallyDelivers high-quality, scalable workI highly recommend Tepia Co without hesitation. They have been a trusted partner in bringing RELI to life, and we look forward to continuing to work with them as we grow

Flowty is a blockchain-based platform providing various transaction services around NFTs. K-Optional wears many hats in support of Flowty including Front End, Back End, business strategy, SEO and more.The K-Optional team has been incredible to work with. They are proactive, supportive, smart, thoughtful and, most importantly, fit seamlessly into our team and company culture. To put it succinctly, we tried to hire them full-time...and then tried to buy their company to acqui-hire them.Some of their strengths include: reliability, responsiveness and creativity. There are many groups out there that can perform some version of the work we are looking for. There are not many groups that are responsive at all hours of the day, deliver consistently and able to present data-backed business strategies.

Our main goal was to update our web presence to more accurately represent our proficiency in IT consulting and services. Our prior website was disorganized, had poor performance, and failed to adequately convey our expertise in customer relationship management (CRM), customer communications management (CCM), and content management systems (CMS). We required a highly functional, aesthetically pleasing, and scalable website that could captivate users, offer smooth navigation, and blend in seamlessly with our current technology stack.They have perfect attention to detail. They took care of everything, from making sure the font and color scheme matched our corporate identity to making every user interaction as efficient as possible. The outcome was a website that serves as a potent instrument for business expansion in addition to being aesthetically pleasing. They were always helpful and quick to respond when we had questions after the launch.

We occasionally utilize outsourced resources to increase our team's ability to satisfy the commercial demands of our clients. This time, my goal was to create and enhance the products we were providing to clients. Their engineers joined our own team to work on the project, creating MetaTrader-based software for our traders. They assisted us in creating and refining a suite of services that give our clients more functionality; up until that point, the solution had been erratic and unconventional. Their most recent endeavor was the development of an income trading module. We employed a scrum methodology with sprint deliverables and agile planning. Along with narrative points, we also used our in-house bug tracking application for project and task management. Everything was really accurate.

Travelers can also quickly spot deals or limited-time offers with just a glance.One of the coolest parts is how the app keeps guests updated when theyre checked into a hotel - whether it's on-site events or nearby activities, theyll get notifications straight to their phone. The feedback system they added is a game-changer. Guests can send questions or share thoughts right from their rooms, and they get notified the moment theres a response.
