|b| Practices

Our practices

Six practices covering what really matters — architecture, e-commerce, APIs, design, performance, security.

01

Critical web applications

High-traffic interfaces and demanding business applications, built to hold in load, accessibility and scale.

  • React, Next.js and Astro — SSR, SSG or ISR as needed
  • Single-page, multi-page and micro-frontend architectures
  • Progressive Web Apps and offline experiences
  • Real-time via WebSockets or SSE
  • Clean separation between front, API and domain
02

E-commerce platforms

High-conversion checkouts, dynamic catalogues and secure payments — headless or integrated commerce.

  • Custom Shopify Plus and headless architectures
  • Certified payments: Stripe, PayPal, Mollie, Adyen
  • Large-scale catalogue management, ERP sync
  • Funnel optimisation, structured A/B tests
  • OMS orchestration and multi-channel sync
03

API & integrations

Versioned, documented and secured APIs — REST, GraphQL or tRPC — for durable system integration.

  • Idiomatic REST APIs and OpenAPI specs
  • GraphQL, federated schemas, fine-grained caching
  • ERP, CRM and third-party integrations
  • Microservices and event-driven architectures
  • Interactive docs, semantic versioning
04

UI design & accessibility

Sober, accessible and consistent interfaces — backed by a documented design system and component library.

  • Mobile-first design, multi-screen adaptation
  • Design system and React component libraries
  • WCAG 2.2 AA compliance, screen-reader audits
  • Sober micro-interactions, performant animations
  • User tests and traceable iterations
05

Performance & Core Web Vitals

Measure, optimise and continuously monitor Core Web Vitals — for interfaces that stay fast under load and over time.

  • LCP, INP and CLS optimisation via Lighthouse audits
  • Code splitting, lazy loading, SSR streaming
  • Optimised image pipeline and edge CDN
  • Cache strategies: edge, HTTP, service worker
  • Performance budget in CI, Lighthouse ≥ 95
06

Security & observability

Harden the app and keep visibility on production — without sacrificing delivery speed.

  • OWASP Top 10 audit, SAST and DAST in CI
  • Security headers, strict CSP, tight CORS
  • Secret management and rotation automation
  • Traces, metrics, logs via OpenTelemetry
  • Alerting on contracted SLOs
