About
I’m a Senior Full Stack Engineer and Frontend Engineer who’s spent 9+ years turning slow, fragmented web systems into fast, reliable platforms teams can confidently build on. I own frontend architecture end to end—from rendering strategy and performance to the design system my teams ship with—while backing it with pragmatic backend work using Node.js, Express/NestJS, GraphQL, and PostgreSQL when the product needs it.
Across my roles, I’ve delivered measurable outcomes like faster initial load times on data-heavy dashboards, higher team velocity through an enterprise-grade TypeScript design system, and smaller, smarter API payloads for mobile apps. I work remotely with distributed teams in English and use AI tooling deliberately to speed up the mechanical parts of development, so I can focus time on architecture, product decisions, and building maintainable solutions.

Owned frontend architecture for Fusion (Sky Ecosystem public governance & finance dashboard) in Next.js, improving perceived speed by rebalancing server vs client rendering and reducing first contentful paint time by 40%. Architected and maintained the Powerhouse design system in TypeScript and Tailwind, increasing team development velocity by 30% through reusable, documented components. Built caching and revalidation patterns (SWR) to make a data-heavy financial product feel instant despite high-latency upstream APIs. Developed specialized UI for document-processing workflows by converting unstructured files (PDF/Word) into queryable, auditable data. Built internal QA/evaluation frontend to provide organizational visibility into QA results with clear visualizations and reporting interfaces.
Led frontend architecture for Fusion, an asset-management platform handling real-time financial data; redesigned SSR/CSR rendering strategy to mitigate high-latency external APIs, achieving ~40% faster First Contentful Paint and improved load on critical dashboards. Built UI for a document-intelligence platform converting unstructured PDFs/Word into structured, queryable data; Architected and maintained the Powerhouse Design System (TypeScript + Tailwind + Storybook) to deliver reusable, accessible components and increased team delivery speed ~30%. Implemented SWR revalidation and caching to stabilize UX against high-latency financial APIs; built an internal QA/evaluation framework with visualization and human-readable reporting interfaces.
Reduced mobile over-fetching by designing and optimizing GraphQL schemas and resolvers in Node.js, cutting API payload size by 50% and improving responsiveness. Shipped React Native applications for industrial logistics and inventory management with real-time tracking and offline-capable data flows backed by GraphQL/Node.js services. Improved reliability of complex multi-step forms by standardizing React Hook Form patterns and consolidating validation logic to remove recurring production bugs.
