We solve client tasks
Learn English By Listening Mobile App
A mobile product designed to help users learn English through a game-like experience, with video lessons, podcasts and instant subtitle-based translation for audio and video content.
Task
The client wanted an app where users could not only learn new phrases but also track and verify their progress, with the learning experience delivered in a more engaging, game-based format.
Solution
We built a mobile app that helps users improve their English level by level. We added interactive quizzes to test progress and introduced subtitle-based learning for podcasts and videos, allowing users to highlight English text and see an instant translation while listening.
Smart English Vocabulary Mobile App
A mobile app where English vocabulary is organised by topic and category. Alongside the translated dictionary, the product includes an AI assistant and game-based exercises for skill reinforcement.
Task
Build a mobile app that would serve as a structured dictionary of English vocabulary for learners.
Solution
We suggested dividing vocabulary into professional and thematic categories. We introduced progress bars so users could monitor progress within each dictionary, added an AI assistant for learning prompts and built several mini-games to help learners retain new material more effectively.
English Teacher Mobile App
A mobile English-learning app containing structured lessons, instant feedback based on user testing, audio playback and progress tracking.
Task
Replace the role of a traditional English teacher with an application that allows users to study lessons independently, in sequence, and receive immediate feedback while learning.
Solution
We built a mobile app with a broad library of lessons across multiple topics. The product combines audio-based learning with written exercises and explains incorrect answers in text so users understand the material rather than simply seeing that they were wrong.
Relocation Assistant Mobile App
A mobile app that helps users identify the most suitable country for relocation and access up-to-date information about each destination.
Task
Build an application that would guide users through relocation decisions.
Solution
We created an app featuring a wide range of countries, each with categorised information. Users can explore sector-specific insights, discover places they may want to visit, read important local news and review the legal context of each country before relocating.
Video-to-Textbook Learning App
A mobile app that turns YouTube films and series into English lessons by analysing video content, showing subtitles with word-by-word support and generating interactive exercises from the vocabulary used.
Task
Create an application that could teach users through external content rather than relying only on proprietary learning materials.
Solution
We developed an algorithm that integrates with the YouTube API, extracts subtitles and analyses them to produce interactive exercises such as missing-word and translation tasks. We also introduced search by difficulty level and topic, plus a convenient player with one-tap translation for individual words.
Logistics Mobile Application
A mobile application for freight transport management, designed for logistics managers, drivers and customers. It supports live shipment tracking, order management, trip history and delivery status notifications.
Task
Develop a mobile tool that would improve transparency and efficiency across logistics operations. The client needed a solution that would give every participant in the delivery chain up-to-date cargo location and status information around the clock.
Solution
We created an app with three user roles and role-specific interfaces. Drivers received navigation tools and simple order acceptance flows. Customers received map-based shipment tracking and trip history. Logistics managers received a control panel for all active deliveries, along with push notifications for critical events.
Android App for Book Translation
An Android application that helps users learn English through reading, with AI-assisted translation built directly into the reading experience.
Task
Build a mobile app that could both generate revenue and support language learning, with processes optimised through the use of artificial intelligence.
Solution
We developed a Kotlin-based app with a large multilingual book library. While reading, users can highlight any fragment, translate it instantly and even discuss the translation with an AI assistant to deepen understanding.
Android Alcohol Tracking App
An Android app designed to track alcohol consumption, collect personal statistics and help users reduce or quit a harmful habit.
Task
Create a mobile app capable of tracking alcohol consumption and building meaningful usage statistics.
Solution
We developed an alcohol-tracking calendar with a comprehensive logic model that records drink type, strength, quantity and cost. Users can clearly see how much they spend on alcohol over a day, week, month or year, making the financial impact of the habit much more tangible. We also added a blood alcohol calculator for drivers.
Website for a Stone Workshop Union in Moscow
A website for a company specialising in memorials, monuments and related installation, engraving and production services.
Task
Develop a website for the company, including a full product catalogue.
Solution
We built a website with a catalogue of ready-made monuments, railings and memorial solutions. We also added advanced filtering so visitors could quickly find the right memorial or complex, explore the available materials and narrow products down by stone type.
Corporate Website and SEO for a European Service Company
A corporate website for a company specialising in facility maintenance, building repair, catering and dry-cleaning services.
Task
Replace the old website with a new, attractive and commercially effective version that could attract customers organically without relying on paid search advertising.
Solution
We developed a modern corporate website and enriched each page with SEO copy and metadata. We then supported search optimisation for three months after launch. Despite the short timeline, the site reached the top two results in Yandex and Google for the client’s region and sector.
Ingredients Platform Development
A web platform that helps wholesale buyers find suppliers for the ingredients and materials they need, while giving suppliers and manufacturers detailed product, document and analytics capabilities.
Task
Build a web platform from scratch for suppliers and wholesale buyers, based on the client’s requirements, with direct interaction between both sides and built-in analytics.
Solution
We built a web application on 1C-Bitrix with a content management system for convenient administration. Each user role received a dedicated personal account with appropriate permissions, while suppliers gained custom data-gathering modules and external analytics. Every page was SEO-optimised to support strong indexation.
SEO Optimisation for a Logistics Company Website
A logistics company operating across Russia with more than 100 services and over 20 categories.
Task
Optimise the website for search indexation, carry out a full SEO audit, identify weak points and technical issues, and implement a complete optimisation programme.
Solution
Through refactoring, we improved website performance according to PageSpeed Insights. We analysed traffic, built a semantic core, prepared metadata and SEO copy for every page, and implemented the materials across the site, which helped it rank within the top five search results for target queries.
Paint Ecommerce Store Development
An ecommerce website focused on paint and coatings, with a rich set of features designed to help users understand products and choose the right option.
Task
Create an online store that stands out from competitors, uses a vivid visual language, includes distinctive functionality and supports the client’s idea of calculating the paint volume needed for different types of work directly inside the store.
Solution
We built a web application designed for easy future scaling. We added online colour tinting, enhanced filtering, search, promotions and structured the product content so that search engines could index the entire catalogue effectively.
Learning Platform for Remote Professions
An international platform that helps users learn new professions online, with lessons by topic and mentors who can answer questions throughout the learning journey.
Task
Build a web platform where mentors can teach users who want to retrain for a new profession.
Solution
We developed a web application with several distinct user roles and a full content management flow. The owner can publish new learning tracks, assign mentors and oversee all core processes inside the platform.
News Portal Development Support
A Russian news portal with several filtering mechanisms and an advanced content management system.
Task
Support the implementation of a news portal that editors could moderate quickly and efficiently. The client’s editorial team worked with multiple roles and needed filtering by author, category and tag.
Solution
One of our specialists joined another team to help stabilise high-load processes. As a result, we improved the way data was loaded and retrieved, strengthening overall platform performance.
Website for a Passenger Transport Company in Israel
A corporate website for a company offering both regular and business-class passenger transport, including airport transfer services.
Task
Build a corporate website that customers could use to understand the relevant transport option and access all necessary service information.
Solution
We created a corporate website where users can choose locations, dates and passenger numbers, then book transport directly. The platform also lets users explore the full service range, read reviews, sign in and review the company’s vehicle fleet.
Frontend Development for an Uncensored AI Agent
Development of the visual interface for interacting with an AI agent designed to handle even the most unusual user prompts without restrictive moderation.
Task
Implement the application’s visual layer based on the client’s pre-existing design mock-up, including advanced interface elements and role-based feature separation depending on user permissions.
Solution
Together with partners, we delivered a high-quality web interface aligned with the client’s design. We chose Next.js so the agent’s website would also have strong prospects for search visibility and indexation.
Website for the Sunny Helper Robot
A product website for the Sunny helper robot, designed both to support direct sales and to spread product awareness online.
