Built complex production network/security analytics dashboards with charts and GraphQL for 1,000+ enterprise customers, providing real-time visibility into threats, traffic, and security posture. Delivered WCAG compliance across core B2B pages including keyboard navigation support. Implemented an LLM-assisted development workflow to scaffold dashboards from Jira specs, reducing initial setup time by ~50% across the team. Reduced initial LCP on older and heavy dashboards (~20–30%) via GraphQL query chaining optimization, Apollo cache tuning, and lazy-loading heavy chart/table components. Established skill-multiplying frontend standards: component/storybook library growth, automated test coverage standards with Cypress and Jenkins CI, and reusable component scaffolding with documentation to cut feature development time.

Led frontend for healthcare EHR integration (HIPAA-regulated) scheduling flows connecting patients, doctors, and EHR systems. Migrated scheduling data layer from Redux/Redux-Saga to RTK Query, reducing boilerplate by ~50% and improving state-related bug surface. Decomposed the frontend monolith into microfrontends to enable independent deployments. Integrated Keycloak-based authentication and configured HIPAA-compliant heat/tracking and production monitoring/resolution via DataDog. Maintained and extended an internal component library with strong WCAG AA focus, preparing technical designs and project documentation.

Built an end-to-end UI from zero to launch for a UK-based art market due-diligence B2C platform, defining the frontend stack (TypeScript, React, React Query, Zustand, Tailwind UI, Next.js). Implemented role-based access, Keycloak auth, and API contracts; configured Webpack build optimization. Collaborated with the CTO on product decisions, tested backend endpoints via Postman, and prepared detailed reports for edge cases. Transitioned the project to in-house teams with full technical documentation.
