      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.

      Mobile App Development Review from Matt Rudnick

      Working with Simpalm has been a really positive experience. We hired them to handle the frontend development of our mobile app for iOS and Android, while our backend was already in place. From the start, their team communicated clearly, stayed organized, and met every deadline we set. 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.

The DDC team has been responsive, proactive, and thorough with their work. They are also very transparent about how they operate and how much time special projects will require. We have referred DDC to several clients and partners thanks to their outstanding process and product. DDC is a very professional, creative, and well-organized team.

      My experience working with Design in DC was incredible. Everyone was friendly, approachable, and seemed to genuinely care about helping create the best possible website for my business. They were also invested in making sure the process was one in which I enjoyed and felt taken care of. The regular meetings made me feel like I was a priority and that progress was continually being made. I so appreciated the attention to detail in regards to the user experience. The collaboration in understanding my wishes and desires for the website and user experience was met with patience and paying attention to detail on my behalf. Not only were they taking my suggestions but offering their own to help me maximize the potential of my website. The design and functionality is more than what I could have imagined. I know, undoubtedly, that the work that Design in DC did for me will help my business grow. After wasting money in years past on website designers, I was worried I'd be doing hte same here. I was wrong. I don't think I'll ever need to search for another website designer group again. I would recommend this group to anyone I know. Thank you, Design in DC! It was an absolute pleasure working with all of you!

      5.0★

      Web Development Review from Terry Heller

      As a growing roofing company, we knew our old website wasn't doing justice to the kind of work we do at Preferred Roofing. It looked outdated, was hard to navigate, and didn't reflect the level of professionalism we bring to our projects. We wanted to change that. Our main goals were to create a new website that would clearly show our services, build trust with new visitors, and make it easier for people to contact us or request quotes online. We also wanted the site to work well on mobile phones because a lot of our customers use their phones to search for roofing services.So, we hired JanBask Digital Design to completely redesign and develop our website. We were looking for a partner who would not only build us a great-looking site but also guide us through the process and make sure the site helped us grow our business.They asked detailed questions about our services, customer base, and how we wanted people to feel when they visited the site.Scope of the work included:Designing a responsive website from scratchCreating unique pages for all our services (roof repairs, installations, gutter services, etc.)Adding a clean, easy-to-use contact form and quote request systemThe new website has made a real difference for us. We've received more calls and quote requests since the launch, and customers often mention how easy it was to find what they were looking for on our site. The new layout makes our services very clear, and the site feels clean, modern, and professional which is exactly what we wanted. It has definitely helped us build more trust with new visitors.Project management was excellent. JanBask kept everything organized and walked us through each step. They gave us regular updatesWhat stood out the most was their care and attention to detail. They didnt just build a pretty website they made sure it worked for our business. They didnt rush the process either they truly wanted us to be happy with the final product.

      Web Development Review from Jason Anish

      When we approached JanBask Digital Design, our companyAustin Financial Services, Inc.was going through a critical branding transition. While weve been around for over 40 years and have built a solid reputation in asset-based lending, our online presence didnt reflect the trust, speed, and flexibility we offer to our clients. We needed more than just a website redesignwe needed a digital experience that could communicate our value, streamline how potential clients learn about our services, and ultimately drive real business conversations.We specifically hired JanBask to help us accomplish a few main goals:Modernize our websites look and feel without losing the credibility and seriousness expected of a financial company.Improve the user journey for business owners and financial decision-makers who are looking for fast, flexible credit solutions.Create a strong foundation for future digital marketing efforts like SEO, paid ads, and client onboarding automation.Make the site mobile-friendly and easy to navigate, especially for busy executives browsing on the go.We had tried updating our site with internal resources and freelancers before, but it never really hit the mark. So we were cautious going inbut hopeful.JanBask started the project with a series of discovery calls where they really took the time to understand not just what we do, but why we do it and who we do it for. They dug into our client personas, our lending process, and even how our sales team follows up on leads. It felt like they werent just designing a websitethey were building a tool tailored to how we actually work.What stood out most to us was their ability to translate financial language into something both clear and client-friendly. Were used to dealing in technical lending terms, but JanBask found a way to keep things professional and easy to understand. Thats not easy to pull off.

      Software Development Review from Jonathan Gessert

      We partnered with Orases to develop and maintain a multi-tenant workflow management system and customer portal, tailored to streamline our customers and internal team's creation processes. Our previous systems used dated technologies, but Orases stepped in with a PHP and React solution that transformed how we plan, write, edit, review, and publish content at substantial scale. The system now fully supports our end-to-end workflow, allowing for seamless collaboration across teams while significantly improving overall efficiency.Orases exceeded our expectations by delivering a demo in just six months, with the full application live within eight months. Their attention to detail, consistent communication, and ability to stay on schedule were remarkable throughout the project. Their project management approach was highly effective, ensuring that every stage of development was completed with precision and aligned with our needs.The results have been outstanding. The new system has enabled us to increase productivity, handle more complex projects, and reduce the time spent in content quality assurance and client feedback loops. This has directly contributed to our companys growth and enhanced our ability to scale operations efficiently.What stood out most was Orases's methodical and thoughtful approach. They took the time to deeply understand our goals and delivered a solution that met both our immediate needs and long-term business objectives. Their commitment to excellence and alignment with our vision truly made a difference.Working with Orases has been an incredible experience, and their ability to provide innovative solutions, paired with their outstanding teamwork, has been a major asset. We look forward to continued collaborations with their talented team.

      Meghan Custer's Review Sourced from Google

      Our staff came in with varying levels of AI understanding - some were occasional users, others were at a simple "I've heard of it..." I contracted Orases to help bring my leadership team into the AI sphere, and Nick and his team were a phenomenal resource. They met us exactly where we were and helped us build real, practical skills. What really set them apart was that they didn't hand us some off-the-shelf solution - they built a training program custom to our business and the way we actually operate. Tasks that used to eat up a good chunk of someone's day are now getting done in minutes. And honestly, Nick and Chad are just great people to work with. They really care about their clients' success. If you're a small business looking to get your team actually using AI (not just talking about it), I'd highly recommend giving Orases a call.
