      Staff Augmentation Review from Mitya Smusin

      Solveit managed our comprehensive eCommerce project, developing a full-featured web platform with Node.js and React technologies. The agency also created a Flutter-based mobile app for seamless data synchronization across iOS and Android devices. We were thoroughly pleased with Solveit's expertise and adherence to deadlines. It provided timely updates and communicated openly about our project's status. Solveit's proactive approach and transparency were exceptional, particularly during the staff augmentation process, where the agency efficiently matched us with qualified candidates and facilitated a smooth onboarding. We were satisfied with Solveit's high-quality work and exceptional support.

      iPhone Review from Gabriel Sabadin

      We engaged SolveIt to develop a minimum viable product (MVP) app, including a user-friendly iOS design, an artificial intelligence (AI) model, and a monetization strategy while ensuring General Data Protection Regulation (GDPR) compliance and preparing for future integrations. Despite a tight deadline, SolveIt delivered the app on time and efficiently handled beta-testing within three months, allowing us to gather feedback and launch successfully. We acquired our first 1,000 users within a month of launching the app. SolveIt's team communicated effectively, addressed issues proactively, and maintained a high level of autonomy, bringing diverse expertise that greatly benefited our project. We appreciate the agency's dedication and professionalism.

      Web Development Review from AJ Canty

      We’ve been working with Vention for quite some time and consider them an extension of our team, rather than an offshore vendor. We needed solid mobile developers to work with our in-house engineers to build our Primer SDKs on both mobile platforms. This was not a trivial thing as it required a lot of cross-functional communication, but the Vention team was up to the challenge. They quickly adopted the best practices we follow at Primer and proved to be effective and proactive.

      BHW is hands down the best contract development team I have worked with. They are honest, extremely responsive, detail oriented, talented, and always on schedule with deliveries. We engaged them on a fixed fee development project and upon completion, transitioned to monthly resources to augment our internal development team, so we could maintain the newfound development velocity. Highly recommend them for mobile app & web development as well as design services.

      Over the past four years I've worked with BHW on several projects and I am happy to give them my highest possible recommendation. They've done more than just build apps for our organization, they've provided robust and creative solutions to help meet our business needs, and it is no exaggeration to say that these solutions have played a crucial role in our rapid growth.The BHW team is friendly, responsive, and professional; and not only do they really know the technology, but more importantly, from our point of view, they know how to best apply the right technology to our particular environment. As mentioned, they have my highest recommendation and I'm sure we plan to continue working with them for years to come.
