At Keep Calm, I delivered custom real estate web products end to end, including solutions for PIK, a major Russian real estate developer. I progressed from Mid-Level to Pre-Senior internally while working across more than five projects.

I led frontend architecture on two projects, including one built from scratch, and built a reusable React component library to standardize UI work. I reduced Next.js page load time by approximately 30% and unnecessary re-renders by approximately 50% through profiling, lazy loading, duplicate-request removal, and render optimization.

I also shipped an internal real estate admin portal using TypeScript, React, MUI, and Zustand, and built a JavaScript interface integrated with WhatsApp Business API and amoCRM API. I introduced Jest and Playwright testing, contributed to CI/CD, conducted code reviews, and managed releases to production.

Earlier, at Ginoice, I built React applications for Web3 and iGaming clients, including wallet integrations with MetaMask, EVER Wallet, and Solflare. I enjoy getting up to speed quickly, resolving systemic code-quality issues, and helping teams ship stable frontend products.
