About

I build frontend for products where a UI bug isn't cosmetic — it's a compliance incident. For 9+ years I've specialised in React, Next.js and TypeScript, most recently as the frontend point of reference for a 12-engineer squad on Goldman Sachs's Marcus US digital banking platform (via Cognizant). I ship the regulated journeys most teams avoid: KYC onboarding, customer consents, tax compliance, referrals and promotional-rate campaigns, from Figma handoff to production. What I've delivered there: +2% conversion lift on Marcus.com onboarding through iterative UX and flow improvements, with full KYC/regulatory compliance Test coverage raised from 61% to 80%+ (Jest, Cypress), cutting regressions across releases WCAG 2.1 AA applied across customer-facing features React/TypeScript coding patterns set through code reviews; mentored 2 frontend engineers; introduced AI-assisted workflows (Copilot, Cursor) to the team Before frontend, I spent 6+ years in QA for US and UK banking systems. That's why I think in edge cases and audit trails, not just happy paths. Outside work I build in the open: a measured frontend performance case study (Lighthouse 52→88), a WCAG 2.2 reference library for fintech UI, a published React component library (@practics/ui), an LLM evaluation layer for regulated apps, and a browser-native virtual try-on with an MCP agent loop on top. Recent interest: making frontend apps agent-callable via WebMCP. Looking for Senior Frontend Engineer / Frontend Tech Lead roles on high-stakes products, in fintech GCCs, product companies or remote international teams. 🔗 Portfolio: pravoobi.github.io · GitHub: github.com/pravoobi ✉️ pravubi@gmail.com
