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.
ТОВ ХОТНАЙТС's Review Sourced from Google
Flyaps delivered outstanding results for our e-commerce store! They built a visually stunning and high-performing website that perfectly captures our brand. Since launching, our site speed has improved by over 60%, and we've seen a noticeable increase in our conversion rate. Their team's technical expertise is top-notch, and the new admin panel they created has made managing our operations so much easier. I am happy to recommend this team of professionals.

UI/UX Design Review from Wladimir Wolinski
Communication was smooth either through our teams communication channel or with the project manager via email. We were in daily contact with the UX/UI designer in form of dailies or when we had to clarify some questions. With the project manager, we had a short conversation every 2 weeks to clarify all possible questions.We personally love to work in a very process-oriented way. Because when we understand how to do something, we usually know how the end result can look like. With Digis, we also had the feeling that they knew what they were doing and how to do it. Every next step was planned from the beginning. If something didn't work in line with our processes, we could readjust it.We were basically satisfied with everything.
Website Redesign Review from Michael Wilson
Digis is redesigning our website to a magento based platform to migrate from a Wordpress based platform. Key deliverables include a full discovery document to determine and outline the scope of the work and the magento platform with custom development to fit our needs.Everything has been delivered on time. Danila our project manager has great communication and always responds in a timely manor. We always receive clear explanations and detailed time logs for the work that is done.
Mobile App Development Review from Gina Levy
Both the developer and tester have exceeded expectations. Their performance is excellent. Together they eliminated bugs, introduced new features, and ensured that the app is working without problems. Previously, we had many complaints in the app store. Since working with this developer and tester, these complaints about the app functioning and bugs have disappeared.The time zone different is sometimes challenging, since we are in California and they are in Europe.

Overall, the team made the corrections and implemented solutions to enhance the client's services.
Mobile App Development Review from Anne Diganova
A women's clothing retailer hired Surf to assist in the development of their app. Thanks to Surf’s efforts, the client was able to release the app on Black Friday, saving 40% of their budget. The team was communicative, responsive, and professional throughout the engagement. They worked in a very organized way, taking into account all business needs.
Mobile App Development Review from David Dilson
Thanks to Surf's efforts, they successfully created a functional app. As a result, the volume of downloads was over 500 thousand with great ratings in the app store. Moreover, the conversion rates were excellent. Their communication skills and expertise in the industry stood out in the partnership.

Software Development Review from Gabriel Ferrin
We've worked with Datarockets for about 4 years now continuously and have been very happy with our collaboration. We've used them for both frontend and mobile development and they've produced high-quality code and satisfied our project needs. They are a strong team and have helped enhance our own developer culture over the years.
Software Development Review from Alejandro Pérez
We've done a couple of projects with the team at Data Rockets and our experience has been very positive. Communication is great which makes a big difference when running projects with a distributed team in various countries (from our end). Pavel and his team have been always available and reply to emails / requests promptly. When we've had problems they've reacted swiftly and thoroughly.
Software Development Review from Robert Osborne
We had two datarockets' developers working with our mobile team and we were always impressed with their dedication to the project, willingness to go the extra mile and desire to learn and improve. I like that the developers feel as if they part of my team and behave like they want the project to succeed as much as I do.

Web Development Review from James Leonard Ehrlich, DVM
I wanted to outsource front end development while maintaining back end services myself.They started with existing React SPAs, cleaned them up, found and removed bugs, improved user interaction, made clear requests for new endpoints which I implemented and they tested and used.The time difference between my office in eastern USA and theirs in Moravia worked well, as we could meet at their afternoon/my morning and I had the rest of the day to deal with back end or questions they might have.Their professionalism and competency were impressive.I will continue working with them, for years, I hope, in maintenance mode or when we need to expand features.
CRM Development Review from Michal Konopa
New CRM system was successfully rolled out and data was migrated from our old system.Everything was delivered on time. Always willing to adapt to changing needs of the project.

Confusing technical vocabulary with delivery capability.
An agency can speak the right language in a sales call without having shipped a product at your complexity level.
Buyers get sold on the pitch, skip the portfolio audit, and discover the gap two or three months into a paid engagement when sprint velocity collapses, or early architectural decisions start creating problems that are expensive to reverse.
The way to catch it before signing is to directly ask the agency to walk you through a project that went wrong.
An agency with real delivery experience will talk about the specific decision that caused the problem and what they did differently afterward.
An agency without it will describe the outcome without touching the process.
The proposal is the agency's best effort under zero pressure. If problems appear here, the engagement will have larger ones.
Watch out for some of these warning signs:
An engagement contract should define scope, pricing, revision triggers, milestone timelines, and exit conditions clearly enough that neither party needs to interpret anything.
The clauses most likely to work against you and worth negotiating before signing include:
When two agencies carry comparable credentials, similar pricing, and equivalent portfolios, the deciding factor is almost always how each one behaves during the evaluation process itself.
Test these side by side:
| Differentiator | What a strong answer looks like |
| Account ownership | Named engineer with stated seniority and relevant experience |
| Industry depth | Multiple clients in your sector |
| Risk identification | Specific risks called out about your project |
| Communication cadence | Defined check-in schedule, not "we'll be in touch" |
| Response time | Stated commitment, typically 24 to 48 hours |
| Fee transparency | Written, itemized answer given without hesitation |
| Reference quality | Reference offered without prompting, from a comparable project |
Agencies quote more accurately, onboard faster, and make fewer assumptions when the buyer comes in prepared. Have the following ready before the first conversation:
The last item is underrated, as it allows the agency to understand what you have already attempted and thus spend less of your billable time on approaches you have already rejected.

The decision comes down to what you are building and how long you need to build it.
An in-house hire makes sense when software is a core, ongoing function of the business and will likely require continuous iteration and deeper institutional knowledge. An external hire, on the other hand, makes sense when the timeline is fixed or the technical requirements exceed what a single hire could cover.
If the answer to all these questions is “yes,” then likely a specialized agency is a better fit than an in-house hire:
Software development companies in New York typically charge $100 or more per hour, though rates as low as $40 per hour exist depending on the agency's size and specialization. North American agencies more broadly average $70 to $200+ per hour, with New York firms at the higher end of that range, given local market costs.
Here are some factors that drive price variation:
The quoted number and the final invoice rarely match. Notably, research shows that around 70% of software projects exceed their initial budget, with an average overrun of 27%. The gap usually compounds from several smaller add-ons that were not defined at the start.
The most common “hidden costs” include:
The simplest protection from such overruns is to ask for a written breakdown of every category of work that triggers an additional charge before signing anything.
Not by default, and for most buyers, the assumption works against them.
Larger software development companies in New York bring staffing depth, structured processes, and institutional accountability. For enterprise-level builds with complex compliance requirements, multi-region infrastructure, or large concurrent engineering teams, that scale is genuinely necessary.
For most projects, the dynamic tends to invert: your account gets assigned to mid-level engineers, senior oversight is limited, and the relationship becomes transactional once the contract is signed. The senior developer who impressed you in the sales call may not be the one writing your code.
The more useful question is who will lead your project day-to-day. Ask for the name, seniority level, and relevant experience of the lead engineer and project manager assigned to your account before signing.
Here are some situations that justify switching firms mid-project:
If you decide to switch, you will need: full codebase access and documentation, all environment credentials and infrastructure configurations, a list of open bugs and known issues, and any third-party API keys or service accounts tied to the project. Do not assume these will be handed over without being asked for explicitly; make them a condition of the offboarding.
The best window to switch is between major milestones, after a working build has been delivered and before the next phase begins. Switching mid-sprint, or worse, mid-launch, multiplies handoff risk significantly.
