As a contractor, I collaborated in a cross-cultural team while consulting for a US-based client. Implemented a new real-time chat provider (Genesys Cloud) using React.js + WebSockets. Delivered the full rewrite of the client's web portal used by ~700,000 active users, under a tight deadline. Built 30+ accessible UI components (WCAG) across 4 micro-frontend apps. Integrated and managed Contentful CMS with the frontend app to enable pages with dynamic content. Advanced usage of Cursor and Claude: rules, context, planning, implementation, testing and debugging.

Collaborated remotely with a distributed, multicultural team while serving a US-based client. Created documentation that enabled ~15 engineers to ramp-up faster on a legacy application. Mentored junior/mid-level engineers during onboarding.

Owned the frontend and backend applications following a vendor transition. Led an Angular 6 to 18 migration, eliminating ~600 vulnerabilities and ~20 external libraries. Reduced production incidents by ~70% YoY through technical debt reduction. Managed Azure infrastructure (WebApps, Docker, Application Insights, Azure Pipelines). Built a lib of ~40 pixel-perfect UI components during a major rebranding. Contributed to a contract renewal by proposing a six-month modernization roadmap.

Resolved critical UX issues by fixing state management approach and routing strategy. Reduced ~30h/month of engineering effort by improving app state management.

Integrated Strapi headless CMS for dynamic content. Built responsive, mobile-first, pixel-perfect UI for the bus ticket e-commerce platform. Managed Docker images and deployments through Heroku.

Progressed from Support Analyst to Frontend Developer. Migrated customer-facing portal from server-side rendered PHP to frontend SPA. Built a real-time customer tracking portal using WebSockets and API integrations. Managed development infrastructure using AWS EC2, nginx, MongoDB, Jira and Confluence.
