Front End Developer

R&D direction focused on emotional support, loneliness and social discovery products. Took mobile MVPs from concept to production, built AI-assisted automation around product discovery, research and marketing, and shipped TrendWatcher — an internal AI-powered signal-intelligence tool (React 19 / TypeScript / Vite / Vitest / Tailwind v4 / Zustand / Feature-Sliced Design / Supabase / OpenAgpt-4o-mini) that analyses Reddit discussions to surface emerging topics and product hypotheses. Practical AI, driven by what works.

Developer platform, LLM integration into product workflows, Figma MCP / Code Connect, release manager for a multi-package monorepo.

Infrastructure Team (pnpm monorepo with 80+ shared packages powering 6 cross-platform React + React Native apps; Webpack → Vite; Module Federation).

Crypto trading platform used by several million traders. Led 2 cross-functional teams totalling 20+ engineers across Wallet, Billing, Design System and Trading. Built a non-custodial multi-currency crypto wallet on React Native, integrated with wagmi + Rainbow context for the wallet-selector flow — connect, switch, sign, disconnect and wrong-network recovery. Built multi-chain wallet / payment widgets with chain-specific transaction construction, signing and balance display — the primitive layer behind payment-URI and address-display UI. Owned billing, subscriptions and third-party crypto payment integrations end-to-end — payment-provider integration, payment-method onboarding, subscription state, retry / refund flows and the trust-sensitive UX around client funds. Introduced Centrifugo for real-time server-to-client updates across wallet, billing and trading flows, reducing polling and improving freshness for balance and transaction-status UI. Built the Design System from scratch on top of MUI primitives wrapped with styled-components, drove adoption across 7 product teams. Reduced deployment time from 20 minutes to 5 minutes and reduced database costs by 20% via Redis caching.

P2P crypto marketplace and wallet platform serving 10M+ users. Bitcoin-heavy. Joined as one of the first frontend engineers. Helped build Paxful's own non-custodial crypto wallet at 10M-user scale — wallet UI, address management, send / receive flows, transaction states and trust-sensitive surfaces. Shipped P2P payment-method-driven flows across hundreds of payment methods — onboarding, dispute flows, real-time P2P trading chat, orderbooks and crypto calculators. Migrated the legacy AngularJS / vanilla JavaScript codebase to React + TypeScript on a live 10M-user product without blocking delivery — a multi-year, cross-team large-scale frontend migration. Built wallet and transaction visualizations with Recharts across dashboards and analytics surfaces. Contributed to a Reactstrap-based Design System adopted by 8 product teams.

CFD brokerage / trading platform — regulated financial environment. Led a small frontend team of 3 developers. Built high-performance web applications and landing pages for a high-traffic trading platform under regulated-broker compliance. Integrated TradingView charts into the trading platform UI. Migrated web projects to Laravel and introduced Vue.js-based SPA architecture. Designed a custom CSS framework and a custom landing-page creator for the marketing team.
