At a digital currency exchange, I design and continue to develop a full-stack service that processes 1,000+ requests per day. I built backend workflows that aggregate crypto and fiat operations, calculate balances in real time, and support reconciliation and dispute resolution.
At M-Invest, I delivered the investment platform frontend from mockups to MVP and implemented real-time order updates and secure investor chat. I also led a team of three developers and automated deployments, reducing the release cycle from hours to approximately 15 minutes.
At ZiphyCare, I designed a FHIR-based medical history module for clinicians and migrated more than 100,000 lines of JavaScript to TypeScript, reducing production runtime errors by approximately 30%. Earlier, I built FinTech, e-commerce, and EdTech products, including a Wildberries seller automation service that reduced order processing from days to hours.
