Developed a full-featured online event platform with support for virtual events, including video conferencing. Built the backend in Go, designed the initial frontend using Node.js (v1), and contributed to the migration and development of the React-based frontend (v2). Leveraged WebRTC for video meetings, implemented real-time communication with WebSocket, and managed DevOps tasks, including server setup, email servers, invite management, and CDN integration.

Self-employed and freelancing since 2017, working on a diverse range of projects alongside major commitments. Highlights include writing Solidity smart contracts, developing a blockchain indexer in Rust, experimenting with LLMs, text generation, and text-to-speech systems. Built various microservices, such as a URL redirect service configurable via DNS. Created custom GitHub Actions to automate testing and deployments and managed my own Kubernetes cluster. Dedicated significant time to exploring and learning new technologies and coding techniques.

Developed and maintained backend services in Go, including a blockchain-integrated payment system for the official Sky Mavis merch store, handling over 70% of sales during the first merch drop. Built various microservices for data aggregation and manipulation, and a fleet of Discord bots with a combined reach of 2.4 million users across 700+ servers. Notable projects included a "Postgres as a Service" bot for provisioning and managing PostgreSQL clusters and databases on demand, and the complete rebuild of "AxieBot," improving efficiency, stability, and feature set. Managed DevOps for the team I worked with, including server setup, monitoring, and infrastructure, and supported community developers through guidance, code reviews, and documentation direction.

Developed and maintained a blockchain-integrated video platform that allows users to upload and monetize content using the STEEM (now Hive) blockchain. The platform enables features such as liking, commenting, and subscribing, with video descriptions and comments stored on the blockchain. Built the backend in Node.js, utilizing S3 for video storage and a custom-built encoding queue in Visual Basic with FFmpeg to process videos into multiple qualities and generate M3U8 playlists.
