EXPERIENCE

Ex Corp Senior Software Engineer (Frontend) - Market & Payments March 2022 – Present

Was responsible for frontend development of the marketplace and payment solutions, including crypto payment integration ($500k in 4 days) and launching a P2P marketplace from scratch as the sole frontend engineer.

Implemented an event-driven model, which enabled launching the P2P mode across the entire platform. Result: over 127,000 transactions with a total turnover exceeding $4M in the last week; approximately 44,000 weekly active users.
• Payment Gateway & Crypto: Refactored business logic during the integration phase, preventing missed deadlines. Designed an asynchronous frontend architecture. Result: $150,000 in deposits within the first 24 hours.
• Instant Sell (IS): Implemented business logic and UI for instant item buyout. Optimized handling of asynchronous statuses (SLA 20 seconds), creating a stable liquidity channel. Result: 8,300 active users in the last week.
• Process Automation: Developed a banner management system using JSON and Unleash, reducing the lead time for launching marketing campaigns from 4 days to 2 hours.
• Reduced CI/CD pipeline execution time by 90% by replacing Babel with SWC for test runs.
