I've built brokerage, fintech, B2B marketplace, SaaS, and operational platforms with React, Next.js, and TypeScript for OtetMarkets, Quarkino, TaxDo, TreeIntel, and other product teams.
At OtetMarkets, I architected a brokerage platform front end from the ground up, creating reusable component, typography, color-token, and motion foundations. I built fiat and crypto deposit, withdrawal, and transfer workflows, strengthened authentication with OTP/TOTP 2FA, and implemented Sentry observability.
I also refactored an ETF investment platform around Next.js Server Actions and TanStack Query, improving page-load performance by 30%.
Across marketplace, CMS, travel, legal collaboration, tax, and workforce-management products, I've delivered typed API integrations, responsive interfaces, search and filtering, payments, real-time experiences, localization, SEO, and multi-step workflows.
