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.
