Yellow

Role: the CEO of Twinslash. Yellow helped us create a chat architecture and a design for the chat. This agency had the relevant experience in working with chat apps, so we opted for them. They started the general scheme of chat flow, which we appreciated. They also offered some tech solutions for each development step. Then they created several wireframes and offered a suitable tech stack. In the end, we formed the final tech stack and started the development process.

Mobile and Web Development — Their communication is definitely one of the strongest sides Yellow developed the web application’s backend for both iOS and Android. For some projects, we provided them with mockups and wireframes beforehand, but most of the time, they start from the beginning. They provided us with detailed reports and a weekly timesheet, and every 2-3 days we communicated via WhatsApp.

We already knew Yellow since we have already completed a web development project together, so we decided to choose them to embark on the design project for an iOS app. We needed some illustrations for onboarding, a simple UI/UX design for main screens, and the logo redesign. First, they created several illustrations in three styles, then via A/B testing we chose the final version and finished the rest of the project in that style. Since we worked together before, it was easy for us to coordinate the processes and find a common ground.

Our team needed a chatbot for customer service. The features should include sending automated messages, asking questions, collecting info for a database, and routing clients to representatives. Yellow had the necessary experience and expertise, so we started working with them. Yellow is very proactive and honest with their reporting. We barely encountered any issues while working with Yellow, and if we did, they used everything possible to handle it smoothly. We were constantly on the same page with them.

I'm the CEO of SLON Media. Yellow helped us develop iOS and Android apps for the internal workflow. At first, they developed an MVP, and after testing and discussion with us, Yellow built the whole app. They were extremely precise and fast in the delivery and always carefully listened to our feedback. All tasks were completed on time or ahead of schedule. Also, their project management skills are excellent. The team was always accessible and attentive to everything that we had in mind. They were extremely proactive and attentive.

. Our app works with projects for business investment and real estate opportunities. The challenge was to update our existing web app and add more functionality to the marketplace. Yellow was able to optimize the performance and fixed bugs to get us back on track. Now we are working on the admin panel for us to monitor the platform. Yellow has done extremely well at completing the tasks we ask of them. I enjoy working with our PM at Yellow and they make it easy for us even though we're based in California.

Yellow helped us create a progressive web app (PWA) for one of our web projects. We needed it to be as fast and trouble-free as possible across all devices. We worked with a project manager, a developer, and the Head of Business Development, and all the team completed the task extremely efficiently. We prepared all the necessary requirements they asked us to, and the final product came out with incredible quality. The level of their commitment, attention, and proactivity truly surprised us. The communication between teams was good, we were always on the same page, and all standups and updates were understandable and on time.

Coverium is a platform for sharing cover songs, it ranks videos by the number of views, likes, and comments, and also arranges them by time, type, and the number of performers. The community started growing significantly, and I wanted to implement more features like chat and YouTube integration. I provided Yellow with the specifications, and they truly exceeded my expectations. This was a full-stack project, and we had some backend already written with Java Spring Hibernate and the frontend was done with Bootstrap and jQuery, but Bootstrap wasn’t able to adapt to the screen on some pages. Yellow fixed it with a more flexible UI, and also provided us with QA services. Users enjoyed the updates and gave positive feedback. I really liked how transparent they were. Yellow and I had frequent communication and I was able to see the updates daily and reach the team if needed. They truly felt like an in-house team, not an offsite company. I was surprised by the kind of performance they had provided. We finished the project ahead of the deadline, so we were able to work on additional improvements. As a client, I am completely satisfied with their performance.

Racefully is a virtual activity tracking platform primarily delivered via a mobile app. We wanted to release the initial iOS version as soon as possible, but taking into account the high competition on the market, we needed it fully-featured. To achieve this, we decided to increase our development capacity using a third-party company, and Yellow was our choice. Two developers and a QA from Yellow worked with our in-house developers and UX designer to help create the app. They organized a consolidated team with our developers and built both the front and backend. Yellow was also responsible for QA. They worked well within our instructions and productively responded to feedback. We enjoyed working with them and would definitely use them again.

The Driver Rehabilitation Institute is a non-profit organization that works with people that have medical conditions that may keep them from driving, such as stroke or traumatic brain injury. We started working with occupational therapists, but we soon found there was a demand from people all over the world. We wanted to create a video-based game app that taught people how to focus their attention while driving. We asked driving instructors from different parts of the world to film the route they use to train their students. We made important objects in these videos - like traffic signs, pedestrians and brake lights - "clickable" We collaborated with Yellow to implement those features, and they totally nailed it. They quickly figured out how to make certain areas of a video clickable, delivered a proof of concept, and then developed an entire Android app. Yellow is a team of highly experienced developers and designers. The UI/UX is visually pleasing and user-friendly. They approached the development process methodically, and kept us up to date as they progressed. What do you like most about the company? Yellow was truly interested in the project through the entire process. They pulled in appropriate talent and engineers with experience as needed in the development. They thought outside the box and were ready to provide us with new tools and solutions. What they should improve on? Nothing crosses my mind.

We needed an experienced team to replace the previous one on the development of a management solution for small tax firms. They had to start working with a code they didn’t write, but they quickly figured out how to get on board with the project and handle it right. We had a mobile-responsive, minimum viable product (MVP), and Yellow finished the development through the final version of the app. Now we have a fully functioning portal that meets industry requirements for personal data, such as social security numbers and year-end numbers, and integrates real-time chat features. The portal now is an industry leader. Yellow was able to interpret our goals right and build a user-friendly platform for small tax firms. What makes Yellow stand out is their ability to pay attention not only to the code but to the results and clients. All members of the Yellow team cared about the product. They don’t just start coding right away but instead, they look at the big picture first. I can’t think of anything they have to improve on, it was a great experience to work with them.

We hired Yellow to act as our web development team, helping us deal with the new web functionality needs of our clients. Their team was the most skilled among other vendors we considered. Their main tasks were to optimize web speed, website development and updating, and bug fixing. Their performance was great: site speed was increased by 10 (Google speed optimization), which enhanced user experience and SEO. Language and time difference are never an issue, we communicated smoothly via Skype and email and everything is great.
