Development ofheadless & custom e-commerce(front + backend) across complete user journeys: marketing pages, catalog, search/filtering, cart, and checkout funnel. High standard of execution: pixel-perfect, micro-interactions, performance, and reliability.

Front & UI (Next.js / React)

Faithful design integration, reusable components, clean and consistent UI (desktop & mobile).
Animations & micro-interactions (GSAP) designed to remain fluid and not penalize Core Web Vitals (LCP/INP/CLS).
Careful state management (loading, errors, empty states), clear and "premium" user journey.

Headless Architecture & Integrations

Setup of a headless architecture: decoupled frontend, API consumption, data orchestration, business logic on the app side.
External integrations: APIs / REST, webhooks, third-party services (payment, emails, tracking…), with particular attention to data consistency and state synchronization.

Checkout & Reliability (critical flows)

Implementation/validation of sensitive flows: cart → checkout → confirmation, Stripe, webhooks, order statuses, edge cases.
Robust error handling, retries, idempotency, payload validation, basic monitoring to prevent "lost orders".

Performance & Production Deployment

Optimizations focused on Core Web Vitals: caching/CDN where relevant, TTFB reduction, bundle/image optimization.
QA/testing, deployments, and light documentation so the team can iterate with confidence.
