      I recently worked with CMARIX to develop an ecommerce website for my clothing brand, Aven Style, and it was a good experience overall. The team was easy to communicate with and really took the time to understand my needs. They created a site that looks great and functions well, making it easy for my customers to shop.

      We came across CMARIX through a mutual friend who had worked with them and had given a reference. We were looking for agency to design and develop our website and were looking for someone who had sharp UI/UX expertise. Looking at their dribble portfolio we knew we wanted to work with them since they were not just doing designs but solving aesthetic problem and increasing user conversions. We were extremely happy with our work experience and would definitely give them 5 star for that collaboratio

      Web Development Review from Lathan Ashton

      RichestSoft was tasked with taking our existing templates, upgrading them to the latest version of our CMS, and deploying them to a staging environment. They also updated the designs for all subsections of the site. The site is fairly generic, consisting of static pages with links from the homepage to product descriptions, case studies, and more. Our team can easily log into the CMS and update case studies without needing a web developer, which has been a huge advantage. Our primary concern was the seamless conversion of our old templates, and RichestSoft handled this flawlessly. They even suggested ideas like making the site multilingual, though we only needed an English version, so it wasn’t necessary in our case.

      Mobikasa has been a great partner for our e-commerce brands and honestly feels like part of our own team. They really know their way around Shopify, SEO, and site performance, and they’re always quick to jump in when we need help. From improving how our sites run to helping us better understand our data and visibility, their work has made a real difference. Communication is easy and straightforward, deadlines are met, and they’re great at thinking through problems and offering solutions instead of just fixes.

      We hired Developer Bazaar Technologies to develop a user-friendly and efficient car rental app using Flutter to streamline our car rental operations and enhance customer experience. The scope of work included developing a cross-platform car rental app using Flutter, which involved creating user registration and login features, car listing and booking functionalities, payment gateway integration, real-time GPS tracking, and an admin panel for managing bookings and customer data. Key deliverables included the fully functional app, comprehensive testing, and post-launch support. The measurable outcomes included a significant increase in online bookings, positive user feedback on app usability, and a reduction in manual processing time for car rentals. The app achieved a 4.8-star rating on app stores within the first three months of launch. Their project management was excellent. They delivered all milestones on time and were very responsive to our needs, providing regular updates and promptly addressing any issues that arose during development.

      Black Flag carried us from concept to production on a very complex website with multiple interest holders. Designing a website for the California Department of Education means that we serve a varied user base and must adhere to the highest accessibility standards. Black Flag took input from internal teams, educators, and other interested parties that would be accessing and using the site. They adapted their designs to meet the needs of various types of users, coming up with not only attractive design elements, but created code that added automation to eliminate some of the manual updates. Black Flag provided us with a high-quality product and were so much fun to work with along the way. A helpful tip: save some of your funding for ongoing maintenance because once you start working with them, you won’t want to stop!

      The team a Black Flag Creative interviewed our group at key milestones throughout the web design process to thoroughly understand our industry and the goals we want to achieve with our new website. I've been through a number of website updates with just as many web designers and Black Flag communicated with us in terms the layperson can understand, making it easy for us to provide content (both media and text) that would allow them to develop a website with the look and feel we wanted. They are just the right balance of website knowhow and flexibility in their thinking.
