Qubik Commerce
Senior Front-End Engineer
Architected and delivered high-performance enterprise web applications and e-commerce storefronts using Next.js (App Router, SSR, SSG), Angular (v8–v21), and SAP Composable Storefront (Spartacus) with TypeScript and Tailwind CSS.
Built and maintained Backend-for-Frontend (BFF) services and API Route Handlers in Next.js and Node.js, leveraging AI-assisted development to orchestrate, validate schemas, and aggregate distributed microservices, REST APIs, and GraphQL endpoints.
Designed scalable client and server-state architectures with TanStack Query, Zustand, Redux Toolkit, NgRx, and Angular Signals, optimizing change detection and eliminating redundant fetches through request deduplication and server-side caching.
Engineered modular monorepos with Nx and Lerna and published internal NPM component libraries and Design Systems (Tailwind CSS, Angular Material, PrimeNG), accelerating multi-squad delivery by 40%.
Implemented Test-Driven Development pipelines with Vitest, Jest, Jasmine, and Cypress, and maintained CI/CD workflows (GitHub Actions, Jenkins) enforcing lint, build, and quality gates on every deployment, with regression coverage across checkout and catalog funnels.
Optimized runtime performance and Core Web Vitals (LCP, CLS, INP) through SSR streaming, dynamic imports, and bundle optimization, resulting in a 35% improvement in initial load speed.
Audited and enforced WCAG 2.1 AA accessibility, responsive mobile-first UI patterns, and robust authentication and authorization workflows with OAuth2 and JWT.
Leveraged AI-assisted development (Cursor, Claude Code) to accelerate refactors and sprint deliverables, while leading code reviews grounded in SOLID and Clean Architecture principles.
Developed hybrid mobile experiences for iOS and Android with Capacitor and Ionic integrated with Angular frontends, and supported the React Native mobile ecosystem.
