Description: A project that originates from a UK-based startup and now happens to become an international invoice insurance service also operating across Europe and the Nordic region and partnering with the UK’s biggest high street banks. Tech stack:  • Node.js • Angular.js • React.js • Codat  • Webhooks • Socket.IO • AWS • Docker  • GitLab CI • MongoDB • Amazon Elasticsearch Service Scope of work:  1. All the nuances of the project architecture were written from scratch. 2. The development and testing were done in repeated iterations so that we could add new features in every software development life cycle (SDLC). 3. Communication was conducted with the external software engineers engaged in the insurance industry, which helped to solve existing problems and successfully integrate new technological solutions. 4. There was constant sync with the customer's accounting software to generate invoices on-site. A counterparty risk assessment was made based on scores against each risk indicator. The insurance cost was calculated depending on the credit score. After the insurance purchase, the sync with the customer's accounting software continued. The invoice status was tracked, and payment confirmation was awaited. Once the payment was confirmed, the insurance policy was voided.

For this financial statement software solution, we used a Scrumban methodology to preserve and transport the correct functions from the old system to the updated one. 4. We implemented regression testing to ensure we’re on the same page with the client. Read an entire case study here – https://opengeekslab.com/projects/financial-statement-software/  Read More

Description: This blockchain-based project pool consists of several solutions developed from scratch or modernized by our team. Among them are the following: • ICO – this project had a faulty front end that didn’t show the needed data for the ICO functionality. It was supposed to show a certain number of tokens with fixed and random pricing (random pricing was generated from Oracle Chainlink).  • Mobile cryptocurrency wallet – it has SwappID and a simple rewards system. This wallet allows consumers to store and transfer cryptocurrencies and has an integrated decentralized exchange, referral program, and reward system for actions with Swapp Tokens.  • Browser extension – this extension allows or forbids websites from collecting your personal data. It collects and monetizes data, allowing users to sell their information to businesses for tokens. • Token price prediction – smart contracts that allow users to bet on the pricing of crypto-currency. • Marketplace – a smart contract that allows users to sell and buy NFT tokens.  • NFT collections – our team created several NFT collections for the customer. We created smart contracts, white papers, and mining interfaces. • Multi-blockchain network lottery – we created a smart contract that generated a random number for lottery rounds from Oracle Chainlink. Users could buy endless tickets during the round and enter the number into the ticket. • DEX on Cronos blockchain – we worked on the design for this project and released decentralized exchange (DEX) farming using Uniswapp smart contracts and interfaces.  Tech stack:  Frontend:  • React.js • TypeScript • Redux, redux-saga Back-end:  • Node.js • Nest.js DB: PostgreSQL Blockchain:  • Solidity Other:  • The Graph API • IPFS Results:  • We corrected ICO so that the front-end part of the software showed the needed information. • The mobile cryptocurrency wallet app is released on App Store and Google Play with 10+K downloads. • We implemented a mechanism of delayed transactions into the marketplace that enables users not to send their transaction to a blockchain network right after it is formed. • The DEX farming allows liquidity providers to get additional rewards for staking LP tokens, aside from the share they got from each transaction.

Description: Food and grocery, medicine, and cosmetics delivery and collection. Taxi services. The system consists of an admin panel for service operators, an application for customers, and an application for couriers (BTW, we are trendsetters – we deployed an approximate delivery time feature a few months before it appeared in Glovo). The system has the following features:  1. Dashboard covering shift management, fleet management, and detailed order timing management. 2. Courier management. 3. Invoicing. 4. Customer management. 5. Role-based access control. 6. Real-time stats. 7. Rating system. 8. Estimated time of delivery. Tech stack:  • Node.js • Nest.js • TypeScript • MongoDB • Redis • Docker  • NATS • Socket.IO • Bull • AWS • React.js • Next.js • redux-saga • CI/CD Scope of work:  1. For the project, we’ve built a microservices architecture with NATS and bull-queue to maximize the deployment velocity and application reliability. This ensures app scalability, integration with third-party services, reusability, plus efficiency. 2. Microservices ensure fault isolation. This enables continuous and seamless workflow of an application as a whole. 3. CI/CD is configured for both front-end and back-end so that a client can instantly see the result. All changes are deployed to AWS. 4. Also, we applied CQRS, which allowed for maximizing the app's performance, scalability and security.

Description: The app allows golfers to study courses online right in the app, working with instructors to improve their skills and analyze their successes and failures. Tech stack:  • React.js • Redux • Next.js • D3 • Node.js • MongoDB • Koa • NATS • React Native  • Google Maps  • Stripe  Scope of work:  1. Our developers worked on this app in two stages. The first took us around ten months, during which we created a golf app for Android, iOS, and the web and implemented an API with built-in Google Maps. 2. The second stage took us around six months, during which we connected statistical graphics from a web to a mobile version of an app using the WebView tool. 3. We created online and offline versions of an app with a user-friendly design suitable for iOS, Android, and web platforms. Our responsibilities included front-end, back-end, and API implementation services. Results: Our client chose a monthly subscription business model for this product monetization. It allowed them to have stable profits since the app turned out to be easy to navigate and highly functional. All features of golf apps for Android, iOS and the web fully meet the request of our customers. Read the full case study here – https://opengeekslab.com/projects/evidence-based-golf/ Read More

Description: A streaming eSports platform with gambling functionality powered up with tokens. The software has a highly efficient monetization model. It allows users to buy tokens for real money in the live-streaming web app and later bet, donate, or buy additional functionality using tokens. Tech stack:  • React .js • Node.js • Ethereum  • Solidity  Results: 1. We’ve launched an ICO and developed a gaming platform from scratch independently. As an outcome of our solution, the customer has an opportunity to turn both tokens and their eSports streaming platform into two channels of profits. 2. We used the Scrumban methodology, which allowed us to coordinate each move with the business requirements of our customers. This flexibility provided us the opportunity to foresee the growth of the business, better relate to the target audience, and understand the market.

Description: A DApp for creating NFT merch. It is a demo project that barely scratches the surface of what OpenGeeksLab could do.  Tech stack:  • Solidity • Web3 • React.js Scope of work:  1. At our company, our primary focus is on helping people see that cryptocurrency, blockchain, and other innovative technologies have the power to improve nearly any field. That's why we created our line of NFT clothing rather than going the traditional route with a fintech or logistics platform. 2. We built an easy-to-use interface and smart contract on Solidity. 3. OpenGeeksLab wrapped up this NFT merch application’s development in just three weeks. 4. AxentMerch has the potential to generate income from a variety of independent creators. These artists can sell their drawings, which are used as the basis for NFT tokens, on marketplaces, or as physical merchandise. Anytime their intellectual property is used, they will be compensated. 5. With our decentralized solution for clothes, consumers have the freedom to decide how they want to redeem their tokens.
