Actively contributed to the project utilizing a diverse technology stack, including Python, Node.js with TypeScript, RabbitMQ, and SQLAlchemy. In this role, I spearheaded the design and development of Meet Assistant, an innovative tool that simplifies the creation of virtual meeting minutes.Main goals were to achieve accurate and reliable transcriptions and minute generation, enhancing the Assistant's usefulness to users. Additionally, I focused on ensuring the stability and sustainability of backend services, contributing to the project's long-term success.

Focused on integrating over 30 blockchains into a single, cross-platform interface to make blockchain technology easily accessible and user-friendly across all platforms. This involved adopting and tailoring each platform to provide a seamless and intuitive experience for users interacting with blockchains and make bip39 great once againAdditionally, I architected and developed an ecosystem comprising dozens of microservices. This ecosystem provided various capabilities to maintain and enhance a stable user experience on each platform. I heavily contributed to and spearheaded the design and development of projects for desktop, mobile, and browser extensions.Working collaboratively across projects, I was part of a team that included front-end, back-end and DevOps teams. I regularly interacted and engaged with third-party services to ensure smooth integration and operation.Forked and updated dozens of open-source, stale blockchain libraries to maintain , utilize or upgrade cryptographic functionalities essential for project needs.Technical Stack:Front-End Technologies: ESNext/TypeScript, Vue.js, Webpack, Rollup, Gulp, IndexedDB, WebSQL, Electron, Cordova, BabelBack-End Technologies: Node.js, Fastify, Express, MongoDB, PostgreSQL (PG), Sequelize, Docker, and moreRust Ecosystem: Rust, Diesel/R2D2, Actix-Web, LevelDB, Tokio
