      Software Development Review from Ryan Kenning

      HashStudioz Technologies is a huge contributor in helping us update our systems. They've built internal portals for our customer base and our dealer base, and as we continue to grow, we use them to enhance those two solutions they created for us. Regarding the process, we start with a meeting to lay out what we want, whether it's a solution or an upgrade to a solution. We look to them for advice and insight, what theyve seen, and what they think is the best way for us to go theres back and forth communication regarding getting everything set up. After that, they put out a great statement of work for us and have a kickoff meeting to start the task weve known each other for so long that everything is routinary. we are delighted with the functionalities that HashStudioz Technologies has developed over the years, which has streamlined our processes. we also praise their friendly approach to explaining things and making everything smooth.

      Software Development Review from Dan Moscatiello

      We evaluated several proposals and HashStudioz Technologies provided a solution that best fit our organization. There were several vendors and we were satisfied with our options and ultimately selected Fingent. The software had to account for company data, student data, course data and bring those data points together in a complete CRM package. The software is effective and improving our business efficiency and performance. Overall, the engagement with HashStudioz Technologies yielded positive results.They collaborated well with us. Moreover, the team was responsive and accommodating to our needs and change requests.

      Software Development Review from Robert Learney

      HashStudioz Technologies developed our devices UX/UI so we could view and pull data. The goal was to have interface capabilities to turn the data into explainer graphs and the ilk. At the beginning of the project, I provided HashStudioz Technologies team with Arduino-based demo boards that interacted with specialized frontend hardware that captured usable data. I also gave HashStudioz Technologies information about the protocol and data format I was using. HashStudioz Technologies delivered a usable UX/UI that met our needs within two sprints, despite working with hardware they had no experience with. we were satisfied with HashStudioz Technologies's work and project management we had sprint review meetings and project progress meetings with the project manager.

      Software Development Review from Emma Bowers

      John Tomblin has served as the software architect and Chief Technology Officer for our software startup, LabPair, for the past two years. During this time John has played an essential role in developing the LabPair software, helping us hone our business model, and plan our launch strategy. I have been delighted with John's services and look forward to our continued partnership. John enjoys a high degree of success as a developer because he is able to engineer software solutions for a variety of marketplaces, no matter how complex or niched. In additional, he has a highly orchestrated, efficient, time- tested process that he uses to scope software projects and get them programmed to clients' specifications. I have been especially appreciative of how John and his team have been both forthright and accurate in estimating the time and cost associated with project development. By far, my favorite part about working with John is his jovial personality, can-do attitude, and excellent communication skills.

      Software Development Review from Thomas Canale

      In 2022, I realized that I needed to find a software development firm capable of designing and developing a SaaS application that would serve the real estate community's need to create reliable, usable, Competitive Market Analysis (CMA) reports, but do so in such a way that also reduced the creation time by as much as 95%. After meeting John and his team, and talking for several weeks about my project, I knew instantly that Data Titan was the right company. Not only were they attentive to every detail of the project, but they also remained vigilant with communications, managing change orders, and keeping to the exact time schedules set for the two-year project, and its numerous phases. Additionally, John's company used 'Scope Atlas', their company's software development application system, to design every screen before any programming work. Having now been through a two-year development process, I realize this project would have never launched without 'Scope Atlas', John's leadership, his senior team, and most importantly, his considerable expertise and insight in the software development sector. I wholeheartedly recommend John and his company for any software or mobile app development project you may be considering. Thank you.

      Software Development Review from Kara Peterson

      Have you ever had a dream? Have you envisioned greatness? This is who I am, I had the idea, but it was just out of my grasp. John Tomblin is in the business of making your creativity and genius a reality. When I first reached out to John, I thought I was on one track. I have a habit of seeing the end, but all of the details are distractions and I had not given them any thought. I was completely unaware of the scope of my project. John did a year long scope and sequence with me, that turned into consulting. He showed me that there is so much more than the end product. I have worked with technology companies in the past and they do one thing really well, they develop technology. John looks at the project holistically. From when the consumer/customer first engages with your product, to how they will actually purchase the product, to the ease of use of the technology, to the performance of your product, to the marketing - how will you first find these customers, and so much more. John is detail oriented and very organized. Nothing slips past him because of his methodology with his wireframes. He holds weekly meetings to make sure the client (me) and he have both done our "homework" to move the project forward. The meetings also ascertain that we are both on the same page about the project. Working with John is a pleasure; I look forward to our weekly talks. I am certain that he is "on my side" and is looking out for my best interests. The world has gotten very small and it is easy to find someone to build your product. However, it is not easy to find someone who will listen to your dream, help you reach it, look out for your best interests and whom you can put complete faith in.

      Python Django Review from Andrew Stetsenko

      We partnered with Flyaps to build the GlossaryTech Chrome Extension from scratch, including the backend for tech terminology analysis. The goal was to help recruiters, sales professionals, and other non-technical specialists in IT quickly understand the technical terms they encounter every day. The first release shipped back in 2017, long before today's AI tools were available off the shelf. Flyaps built a custom tokenization layer on top of NLTK library to resolve the ambiguity problem - distinguishing "Go" the language from "go to the shop," or "Swift" the framework from the adjective, while also correctly recognizing multi-token terms like "Ruby on Rails" or "Amazon Web Services". It was a pragmatic, precise solution that made the extension genuinely usable from day one. The outcomes have validated that early bet. GlossaryTech now holds "Featured" status in the Chrome Web Store, has passed 25,000 downloads, and consistently serves 10,000+ weekly active users and 2,000+ daily active users. For a niche professional tool, that level of organic, sustained engagement is rare - and it traces directly back to the technical foundation Flyaps put in place. Beyond the engineering, what stood out was how Flyaps engaged with the product itself. They contributed to architecture decisions, flagged edge cases early, and treated scope conversations with honesty rather than upsell. Communication was straightforward throughout, deadlines were met, and the codebase has held up well as we've extended the product over time. I'd recommend Flyaps to anyone looking for a partner who combines solid engineering with genuine product thinking. They've been central to GlossaryTech's success and continue to be a team we trust.

      Software Development Review from Dariia Ryzhova

      Our collaboration with Flyaps has lasted for several major projects, of which I personally worked with them on two. I am very satisfied with the level of expertise (both technical and domain), the involvement and responsibility of the teams, and the quality of delivery. We successfully brought 2 major products to life together. Flyaps teams have diverse specializations, so I had the opportunity to attract consultants from different fields: software developers, including high-level architects, DevOps, QA, and business analysts. The teams have a modern technology stack and are experienced in Agile development. This allowed for smooth integration with internal teams and processes. It is also important to note that Flyaps provides technical consulting on demand, and this was very valuable service as well. Overall, I can recommend working with Flyaps as a reliable and high-quality partner.

      Barbara Cunningham's Review Sourced from Google

      John's ACT program is the complete plan for a business owner to Identify their ideal client, create their marketing message, build out their landing pages and then attract the traffic that is dying to buy their product. The customer desires the product because the message is so on target, so no selling involved! What could be BETTER than that! Along with the online classes John teaches live in small groups and then has a support Q & A call once a week.

      Digital Services Review from Tom Damiano

      i hired this company for three months to do some SEO work. About two weeks in I realized how poorly things were worded and just corny and sales-y the language was. I told them to change it over and over and they couldnt do it. I told them I wanted to cancel and go our separate ways. Now they are currently holding my money and will not give it back.

Sources

DesignRush sustains a directory of over 40,000 agencies categorized by service category, location, expertise, and reviews. We build our database in two ways:

  • Our dedicated team of agency experts actively searches the web for top-performing companies. We then pull information from their websites, online presence, and client testimonials to verify their status and qualifications prior to listing.
  • The agencies listed get notified of their profiles on the website and they can choose to claim it or not, which suggests their availability for more collaborations.

Agencies can also reach out to DesignRush and must go through the verification process prior to being listed.
