Led frontend architecture for a production Web3 platform enabling secure DAO treasury and asset management using Safe and Zodiac Roles Modifier, directly supporting the company’s core revenue stream. Implemented blockchain permission systems allowing asset managers to deposit, borrow, stake, lock, and swap assets, driving a measurable uplift in user engagement across 15 assets and 13 clients. Architected and maintained a component-driven design system (27 reusable components) with standardized CSS conventions, reducing frontend tech debt (UI churn by ~30%) and accelerating feature delivery across teams while preserving accessibility and cross-browser consistency. Converted core services into a SaaS product, contributing to UX/UI design, full-stack development, and cloud migration from GCP to AWS; reduced infrastructure costs by ~20%, achieved 99.9% uptime in the initial post-migration quarter, and established Jest/Cypress automation that raised test coverage to ~30% and reduced production defects by ~40% QoQ. Delivered pixel-perfect, accessible interfaces (achieving ~95% WCAG conformance) with full internationalization (i18n + RTL); continuously audited and improved accessibility and performance using Lighthouse, axe, and custom metrics, raised critical-flow Lighthouse scores to a B+ level, and orchestrated Figmato- production handoffs for 12 key screens, improving first-visit conversion by ~45%. Conducted user interviews with asset managers, translating insights into UX improvements that reduced operational friction and increased usability and operational efficiency. Tech Stack: React, TypeScript, TanStack, GraphQL, PostgreSQL, Redis, Solidity, AWS, Jest, Cypress, Storybook

Owned and delivered the frontend architecture for a data-intensive, real-time, performance-critical Web3 trading and dApp platform on Ethereum as the sole frontend engineer, designing a scalable MVP and shipping ~25% of planned feature scope ahead of schedule, accelerating time-to-market. Built performance-first, accessible, and SEO-optimized, data-heavy frontend workflows for on-chain interactions, maintaining low-latency UI performance and high responsiveness under frequent state updates while implementing accessibility best practices (semantic HTML, keyboard navigation, ARIA, and color-contrast compliance), contributing to measurable improvements in discoverability and core user engagement metrics. Optimized Core Web Vitals (LCP, CLS, TTI) and frontend performance through code-splitting, optimized hydration, caching strategies, SSR/SSG trade-offs, and smart data fetching (React Query/SWR), tracked via Lighthouse, PageSpeed Insights, and WebPageTest. Partnered with the product owner to define product vision, MVP scope, and acceptance criteria, reducing rework through early UX validation and technical feasibility assessments. Standardized the Web3 frontend stack and led engineering standards, documentation, and refactoring initiatives, improving code quality, maintainability, and onboarding efficiency. Collaborated closely with backend and smart contract teams to integrate, deploy, test, and troubleshoot on-chain functionality in production. Tech Stack: Next.js, Typescript, Talisman, IPFS, Subsquid, Ethers.js, Polkadot.js, Wagmi, Viem, Cypress, Prettier & TSLint

Led development of a large-scale MERN-based platform with microservices architecture, supporting admin, agent, and buyer dashboards. Built an online payment system that contributed to a 65% increase in annual sales in year one, followed by 40% YoY growth.
