Web Development Services: Modern Frontend & Full-Stack Engineering

We don't just write code. We build production-grade web applications that are fast, accessible, secure, and maintainable. Every project ships with design system integration, CI/CD pipelines, performance budgets, and 90-day warranty.

Our Web Development Services

4. E-Commerce Development

  • **Shopify Hydrogen / Headless** — Custom storefronts, B2B wholesale
  • **Medusa / Saleor** — Open-source, self-hosted, extensible
  • **Custom Checkout** — React Hook Form + Stripe/Razorpay, optimized
  • **Performance** — LCP <2.5s, INP <200ms, CLS <0.1

5. Migration & Replatforming

  • **Legacy → Modern** — jQuery/WordPress/PHP → Next.js/React
  • **CMS Migration** — WordPress → Sanity/Contentful/Strapi
  • **Zero-Downtime** — Blue-green, feature flags, staged rollout
  • **SEO Preservation** — Redirect maps, canonical parity, Search Console monitoring

Project Delivery Process

Phase 1: Discovery & Architecture (Week 1-2)

  • Technical requirements gathering
  • System architecture diagram (components, data flow, infra)
  • API contracts (tRPC/OpenAPI specs)
  • Database schema design (Prisma)
  • CI/CD pipeline setup

Phase 2: Core Implementation (Week 3-8)

  • Design system integration (tokens → components)
  • Authentication & authorization
  • Core features (CRUD, search, real-time)
  • API development + documentation
  • Unit + integration tests

Phase 3: Polish & Hardening (Week 9-12)

  • Performance optimization (Core Web Vitals)
  • Accessibility audit (WCAG 2.2 AA)
  • Security hardening (CSP, rate limiting, headers)
  • Cross-browser/device testing
  • Load testing + error monitoring

Phase 4: Launch & Handover (Week 13-14)

  • Staged rollout (10% → 50% → 100%)
  • 30-day hypercare (daily monitoring)
  • Documentation + runbooks
  • Team training session
  • 90-day warranty begins

Industries & Complexity

| Complexity | Example | Timeline | Team | |------------|---------|----------|------| | **Marketing Site** | 20 pages, CMS, blog | 6-10 weeks | 2-3 | | **SaaS MVP** | Auth, dashboard, billing, API | 12-20 weeks | 3-5 | | **E-Commerce** | Custom checkout, subscriptions, B2B | 16-24 weeks | 4-6 | | **Enterprise App** | Multi-tenant, SSO, audit, compliance | 6-12 months | 6-10 |

FAQ

Frequently Asked Questions

**Do you only do Next.js?**
Default is Next.js 14, but we've delivered React Native, Vue/Nuxt, Python/FastAPI, Go, Kubernetes. We match stack to problem.

Frequently Asked Questions

**What if I have an existing codebase?**
We audit first (₹50K-1L) — tech debt, architecture, test coverage, performance. Then plan incremental modernization or rebuild.

Frequently Asked Questions

**How do you handle security?**
CSP headers, rate limiting, input validation, dependency scanning (Dependabot), secret management, penetration testing annually, OWASP Top 10 compliance.

Frequently Asked Questions

**Do you provide DevOps/infrastructure?**
Yes — Vercel/Cloudflare/AWS setup, CI/CD, monitoring, alerting, disaster recovery. Or we deploy to your existing infrastructure.

Frequently Asked Questions

**What's your team structure?**
Senior-only. No juniors on your project. Principals do the work. Typical: 1 Tech Lead + 1-2 Senior Frontend + 1 Senior Backend + 1 Designer.
