Led a 4-engineer team to deliver a UX overhaul of MazeMap WebUI, designing an abstraction layer over the legacy FSM—achieving zero downtime and 100% backward compatibility. • Developed a persistent search interface to query multi-type datasets (POIs, Campuses, Rooms), providing a seamless deprecation roadmap for legacy systems without disrupting active users. • Delivered WCAG-compliant keyboard navigation and ARIA attributes across the MazeMap search UI, improving accessibility compliance and enabling full keyboard-driven interaction. • Architected a Backend-For-Frontend (BFF) authentication system for 5,000+ users, neutralizing XSS risks via server-side OAuth flows and leveraging a secure endpoint to hydrate dynamic, UI-level Role-Based Access Control (RBAC) state. • Reduced DOM Content Loaded from 4.5s to 1.8s via route-level code splitting and lazy loading, while eliminating protected route UI flicker through synchronized auth-resolution states. • Engineered a zero-to-one Next.js ROI dashboard adopted by 100% of the sales team, building an SSR-driven flow that protected proprietary calculations and leveraged Zod for strict client-side validation across a multi-step wizard. • Established End-to-End testing using Playwright and implemented CI/CD pipelines with containerized de ployments on AWS using Kubernetes. • Directed real-time incident response for critical production blockers, actively debugging live client environments to deploy immediate workarounds, document RCAs, and ship permanent release patches. • Mentored 2 developers through structured code reviews on TypeScript and Angular, accelerating their path to independent contribution.

Designed a centralized, context-aware login application, unifying the authentication experience across 4 enterprise apps (React, Angular, AngularJS). Applied factory-driven strategy patterns to dynamically serve tenant-specific UI branding and route credentials to the appropriate legacy backend APIs for secure, domain-scoped cookie generation. • Built resilient form submission for vault configuration workflows using React Query’s retry and cache invalidation, preventing data loss on API failures. • Drove the modernization of legacy frontend build toolchains across Angular and AngularJS projects, upgrading Node.js to eliminate high-severity CVEs and stabilize CI/CD pipelines. • Implemented feature flags across 3 products, enabling controlled rollouts and reducing production incidents during releases.
