Full-stack engineer at ComplyControl building a production transaction-monitoring and KYC platform with React, TypeScript, and NestJS.

At ComplyControl, I helped grow an early fintech POC into a production transaction-monitoring and KYC platform. I lead technical decisions and build React/TypeScript features and NestJS APIs.

I refactored core screening and integration flows for speed and reliability, including a pipeline that was around 5x faster and over 10x cheaper in difficult cases.

At Proxy Live Solutions, I built real-time web applications and reusable UI components, and optimized Canvas-heavy interfaces for low-powered laptops.

Earlier, I developed WebGL image-editing features and accessibility tooling at Wix.com, built a Confluence-based enterprise application at EPAM Systems, and initiated a JavaScript digital-signature SDK at PrivatBank.
