Overview About Opengeekslab

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.

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.
