| "summary": "Originally from Saint-Petersburg, earned Master's degree in Computer Graphics (CS) at Baltic State Technical University. Started his career as UI / Web designer collaborating at local startups, prominently kudago.com, with hobby passion for open-source. Afterwards moved to Montreal, Canada, where first collaborated with local businesses (TTBA, Amaze) as frontend / web engineer, then found an opportunity at Plotly Inc as WebGL specialist. Later switched to fintech at Mobeewave, that merged into Apple Wallet and Payments teams. Currently focused at audio / vis tech at elevenlabs.io and open-source projects.", | |
