Founder at GlossaryTech, backed by Dice

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.

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.

Kyle Neely's Review Sourced from Google
Sketchy method of cold calling to get leads by claiming they talked to someone else at my org that they did not in fact talk to. Called on my personal cell phone. Would not do business with them if the engage this this type of misleading lead generation.

Sketchy people would be a polite way to put it.
Kept sending advertisements to a general email box, I responded asking to unsubscribe, they started sending those advertisements to the email from which I responded.
I wouldn't trust these people to do anything.

5 FAQs About Frontend Development Companies in the United States
What does a frontend development company in the US do?
A US frontend developer is a type of software developer who programs the user-facing side of a digital product, website, or application, i.e., the side users see and interactwith. Their role is to create dynamic and easy-to-use user interface (UI) which the user would enjoy exploring.
In this role, their job is to determine the best layout for the website, more specifically to find the best place for the images, how to structure the navigation, where the search bar and drop-down lists go, and more. Much of their work revolves around making sure the overall appearance and layout of the site or app is intuitive for the user.
What services do frontend development companies in the United States provide?
As part of their specialty, frontend development companies in the US provide design and programming services aimed at enabling the best user experience. The main focus is to create stylish and easy-to-use sites that will enable smooth consumer experience, subsequently increasing time-on-site, engagement, and conversions.
Key services of a frontend development company in the United States encompass:
User interface design
Legacy frontend modernization
User research
Wireframing and prototyping
Responsive web development
Progressive web apps (PWAs)
Single-page application (SPA) development
Frontend performance optimization
Accessibility testing
How much do these specialists charge for their services?
When looking to hire frontend development companies in the United States, or globally, businesses can choose to hire junior, intermediate or senior developers, which charge $10 to $30, $30 to $50, and $50 to $100 per hour, respectively.
Drawing on their experience, seniors are the most advanced talent you can go with, with their capabilities expanding to composing code, working with more advanced frameworks, creating websites with version control, responsive designs, and overall, better problem-solving skills.
Other than seniority, the geographic location of the developer affects the hourly rates as well. Countries like Canada, Australia, and the USA are known to hold the highest rates for the service.
What languages and frameworks do frontend development companies in the United States use?
Frontend developers in the United States mainly work with JavaScript, TypeScript, HTML5, and modern CSS (often with preprocessors like Sass or utility-first frameworks like Tailwind CSS).
The core application logic is predominantly built using reactive frameworks and libraries, with React dominating the ecosystem, followed by Next.js, Vue.js, jQuery, Bootstrap, AngularJS, and EmberJS.
For development and operations (DevOps), the standard pack includes version control systems like Git hosted on platforms like GitHub or GitLab.
For other miscellaneous activities, frontend teams also use static type checkers like TypeScript, code quality tools like ESLint, collaborative platforms like Figma for design handoff, and Jira for workflow tracking.
What is the difference between backend and frontend development?
The backend is the engine room of the website or the application that is responsible for the server-side logic. On the other, user-visible end is the frontend that is referred to as the skin of the site.
On the other end, frontend developers in the United States convey design specifications into appealing user interfaces composed of different typography, color palettes, and layouts. They understand how a user’s eye moves across a page.
