👨💻 Challenges: The main task was to develop a social network where everyone can participate in the new creator economy, using U.S. dollars and without understanding the technology of blockchain, NFT or cryptocurrencies. ✅ Results: Our team has developed a marketplace and social network for selling NFTs. It’s a mobile application with its own crypto wallet, where you can create and store minted artworks, collaborate and share profits with other people. Creators post their creations — art, music, photography, video, anything — and their followers repost them. This is how creations are distributed through the CreatoRanch network, and creators expand their digital reach. The main vision is to power the creator economy of tomorrow where anyone can be discovered and compensated fairly as a creator, curator, or collector in an efficient and environmentally-friendly ecosystem. That's why CreatoRanch uses the Tezos blockchain, which is fast, inexpensive and, above all, very energy efficient.
👨💻 Challenges: After the coronavirus pandemic, online shopping increased by 28%. Moreover, 58% of consumers said they expect to do more online shopping after the pandemic. All of the e-commerce marketing pain points that retailers used to face are now more significant. Our team was challenged to develop a universal app that could provide brand management and allow store owners and brand managers to collaborate in one place. ✅ Results: As a result, we developed an e-commerce solution that helps businesses increase conversion rates, increase revenue and reduce the cost of marketing campaigns. The app solves a lot of user problems by giving marketers a built-in image editor. It saves the user time from constantly switching between multiple applications. It has a user-friendly drag-and-drop landing page builder, converting templates, image and icon library, etc. It's excellent for creating and publishing attractive landing pages with the single, well-structured goal to introduce a valuable and clear message to all customers. Using an intelligent tunnel builder, GoGonzo is shaping a new generation of mobile apps for brand advocates looking to create conversion-driven marketing campaigns. ⚙️ Top core features - Built-in landing page builder - Drag & Drop Editor - Quick publishing in real-time - 10+ templates for choosing
▶️ KFP Online - Exam Simulation platform for Australian doctors 🌏 Country: Australia 🇦🇺 📚 Industry: E-Learning, Healthcare 🖥 Tech Stack: Python, Django, HTML, CSS, JS, React.js, Redux, PostgreSQL 👨💻 Background The process of becoming a doctor in Australia can take many years. To get licensed as a general practitioner (GP), a student needs to pass the RACGP Fellowship exam, which consists of the Applied Knowledge Test (AKT), Key Feature Problem (KFP) and Objective Structured Clinical Exam (OSCE). The exam is held twice a year, with around 1,000 students trying to pass each time. ⚙️ Project Based on his wife’s experience with the exam, the founder of KFP Online realized that the studying process lacks exam simulators. His plan was to create a web app that would include case studies and exam modes, constraining certain activities to exam-like timeframes. Rather than being an educational tool, the software would test the student’s knowledge under the conditions of a real exam. ✅ Results Within four months, We Soft You developed a comprehensive MVP, simulating the real exam experience. KFP Online could add new exams through the admin panel and notify its users. The user experience also highlighted suggestions based on the content the users studied less. Two months after, version 2.0 was released, filled with premium content from professional doctors, additional explanations, tips, and tricks. During the first month, 400 people became active users out of 3,000 visitors. And while the historical exam passing rate is just 48%, with KFP Online it jumps to 70%.
