What I'm looking for

I'm looking for a full-time remote role where I can own architecture and delivery, build scalable TypeScript products, and collaborate with distributed cross-functional teams.

I led architecture and delivery at Contaqt for a WebRTC telephony platform serving 10,000+ active users, managing a team of five engineers and reducing production incidents by 40%.

I owned a billing and subscription platform processing $1M+ monthly across Stripe and three payment providers. I also shipped a Chrome extension used by about 90% of customers and handling roughly 30,000 calls each month.

Previously, I helped take CallPanda’s recruitment platform from zero to launch and its first 30 customers in six months. I built end-to-end features including CV recognition, real-time chat, video recording, and online assessments that cut candidate screening time by 50%.

I've also delivered banking-platform features at Sber, led a TypeScript migration and design system at AxisPoint Consulting, and founded and sold an on-demand home-cleaning service after reaching 10,000+ completed orders and $100k in revenue.
