TripBuzz is the example of a startup which has been developed over a few years by our team. The app makes sightseeing across States easier by categorizing the attractions according to the distance and activity type.
The service grows organically, starting from an MVP and is based on a LEAN approach.
Our role has been to choose the best tools, design the software architecture, implement both backend and frontend, adjust it to changes the owners wanted to introduce, suggest the best technical solutions for each new idea, and monitor the app running with huge traffic.
We created background workers which helped with processing large amounts of geo data. A new feature for adding user feedback to sightseeing attractions was developed.
Voting system for attractions, thematic pages templates, and hotel search functionality were added. We introduced individual attraction pages and a mobile version of thematic pages.
We designed the software architecture and implemented the first version of TripBuzz.
TripBuzz relies on geographical data and uses it extensively. The algorithm connects data from the rating system with geo data, allowing us to provide the best attractions for a given location in the search results.
A sophisticated caching system was implemented to maintain the speed of the search engine with a growing user base. To build the cache, we developed a set of background workers that continuously update the cached data.

Waggle is an online store with headquarters in Australia, providing a variety of dog gear. The owners sought a fully customized solution, so they decided to build the online store from scratch with us, without using any ready-made engine.
We are the tech department for Waggle. In this case, the client provided interface design, flows, and graphics to be implemented.
Since 2011, we have been responsible for the backend development and frontend implementation of the web shop. Waggle owners wanted a totally custom solution, so we designed the software architecture, implemented the solution, and optimized it with growing traffic.
Currently, we are still iterating, introducing new functionalities, and improving the internals of the system. The ecommerce platform continues to develop, and the story will be continued.
To improve speed and scalability of the system, we switched the hosting provider to AWS stack. The mobile version of the website was improved.
A series of A/B tests of strategic pages was performed to improve the conversion rate. The checkout process was simplified.
To improve the speed of the website with the growing user base, content compression and caching were introduced. Business reports were added to allow the owners to easily see sales, margins, conversion rates, etc.
We migrated all existing data from the previous version of Waggle ecommerce used before 2011. The new layout of the website was implemented, PayPal Express integration was completed, and the gift vouchers feature was added. We moved the static assets to a CDN server.
We discussed possible technologies and proposed the best for the client’s needs. We designed the software architecture and implemented the first version of Waggle.
The website has been created in a modular fashion, so the whole system is loosely coupled and allows for adding new features easily. The website is integrated with a set of third-party services like payment providers, bookkeeping/repository trackers, and business analytics collectors.
Automatic tests have been prepared to ensure the software remains stable regardless of the changes introduced. Special care was taken to optimize the speed of the website. We performed a series of speed tests and selected solutions that are optimal for the website and the current needs of the business.

Instabook is a browser extension designed to save any webpage as an EPUB file for comfortable reading on e-ink devices. This tool eliminates ads and distractions, allows for offline reading, and takes advantage of eye-friendly e-ink displays to enhance the reading experience across various content types, from academic articles to leisure reading.
This open-source browser extension was created to solve the common problem of uncomfortable online reading experiences. The extension works across multiple browsers (Chrome, Firefox, and Edge) and offers a simple one-click solution to convert web content into a format optimized for e-readers. The project has received positive user feedback for its reliability and functionality.
Instabook enables users to read content on their own terms—offline, distraction-free, and on eye-friendly devices. It serves diverse audiences including students, professionals, and leisure readers by providing a seamless way to transfer digital content to e-ink devices. The extension preserves images and basic formatting while simplifying complex layouts for optimal e-reader display.
The extension was developed as a lightweight browser tool that activates only when needed, ensuring it doesn't impact browser performance or monitor browsing activity. It utilizes the browser extensions mechanism that is supported accross all major browsers. The extension is implemented in HTML and JS and is using additional frameworks (Bootstrap and jQuery) to improve user experience. The project is fully open-source on GitHub, encouraging community contributions and transparency.
A Pro version, that is planned to be released later in 2025, will be a server-side software making it possible to add more complex and resource-intensive features.
User Experience (UX) is about finding the user's measure of "just-right" and exceeding their expectations. It's about going beyond the core functionalities of the product, standing out from the web crowd by knowing with whom and how to lead the conversation.
We've been analyzing users, their needs, fears, and motivations. We have read between the lines, observed, and dug deeper by asking, listening, and researching.
This process led to sketches, prototypes, content strategy, user interactions, and user interface (UI) design to create a product that is usable and accessible.
Experience begins long before a user discovers the product—and continues well after. It’s shaped by everything that happens before and after a person engages with it. Conducting research, analyzing personas, and creating storyboards helps set the scene and design the right solution for the target audience.
For this project, we utilized Proto.io, Adobe Creative Cloud, Lookback, and Typeform for research and prototyping. We also leveraged Google’s organizational and SEO tools, Chrome Developer Tools, a ticket system, paper, and drawing tools.
When inspiration struck—whether while running, in the shower, or during meetings—we captured ideas with a camera or phone voice recorder. Since we couldn’t test on every device worldwide, we used apps like Spoon for cross-browser testing to ensure compatibility.
This custom platform was created for an aviation company in Canada to manage flight schedules and crew assignments. The system, featuring components like the Aviation Language Assessment Tool, enables smooth language proficiency level assessment and provides different levels of access and rights for each user type.
We analyzed the company's internal processes, needs, main user groups, their problems, and goals to design the product's architecture. We implemented the solution from scratch, tested it, and developed additional functionalities as needed.
The result eliminated repetitive work, provided faster access to information, simplified progress assessment, and brought absolute clarity to company operations.
We used a Domain-Driven Design approach, working closely with the client to define domain details and design a flexible, configurable architecture—particularly crucial for the booking system. Comprehensive specifications ensured alignment between client and developers from the start.
To keep the assessment tool secure, we implemented logic preventing abuse through effective browser-server communication. Technologies included Java, Docker, and PostgreSQL.
