Web & Mobile Applications
Sub-second load times. Lighthouse 95+. Ships in 2 to 3 weeks.
High-performance web applications built with Next.js App Router, server components, and edge-optimized delivery. We do not bolt on responsiveness at the end. Mobile-first layouts, Core Web Vitals, and accessibility are constraints from day one, not a QA checklist at launch.

CAPABILITIES
What we build
01
Server-side rendering and static generation
Next.js App Router with React Server Components for pages that do not need interactivity and client components only where state is required. Static generation for marketing pages, streaming SSR for dynamic dashboards. Zero client-side waterfall for above-the-fold content.
02
Progressive web apps
Service worker caching, offline-first data strategies, and installable manifests for applications that need to work on flaky connections or in offline-capable contexts. No app store submission required.
03
Performance optimization
Image optimization through Next.js Image with proper sizing hints, font subsetting, code splitting on route boundaries, and lazy loading below the fold. We measure LCP, CLS, and INP before and after every deploy on mobile hardware, not a desktop DevTools simulation.
04
Accessibility and cross-browser fidelity
Semantic HTML, ARIA roles where the browser does not provide them natively, keyboard navigation, and color contrast ratios validated against WCAG 2.1 AA. Tested on Chrome, Firefox, Safari, and on iOS and Android devices, not just a macOS Retina display.
BUDGET
Core Web Vitals performance budget
Performance is a constraint, not a finishing touch. Every PR runs Lighthouse against a throttled mobile profile. The build fails if any metric busts the budget. Measured on a mid-tier Android device on a simulated 4G connection, not a desktop browser.
| Metric | Budget | What it measures | Common cause of regression |
|---|---|---|---|
| LCP | < 1.5s | Largest contentful paint | Unoptimized hero image, blocking font load, server response time. |
| INP | < 200ms | Interaction to next paint | Heavy JS on main thread, unbounded effect re-runs, synchronous storage reads. |
| CLS | < 0.1 | Cumulative layout shift | Images without dimensions, late-loading ads or banners, web fonts swapping. |
| TBT | < 200ms | Total blocking time | Large bundle splits, hydration mismatch, third-party tag manager. |
| JS bundle | < 170 KB gzip | Initial JS payload | Unused component libraries, full lodash import, client-side analytics SDK. |
| Image weight | < 200 KB above fold | LCP image transfer size | PNG instead of AVIF or WebP, no responsive srcset, hero image not preloaded. |

APPLICATIONS
Where this applies
- 01Marketing site with CMS and dynamic content. Next.js frontend with a headless CMS behind a typed API layer. Marketing team ships page edits without a deploy. Lighthouse performance score: 97. Time to first contentful paint on mobile: 0.8 seconds.
- 02Customer-facing web application with real-time data. A fintech dashboard streams live market data via WebSocket into a React component tree that updates 10+ charts simultaneously at 1-second intervals without causing layout shift on the surrounding page.
- 03Admin dashboard for operations. Internal platform for a logistics company showing live order status, warehouse queue depths, and SLA breach indicators. Renders 5,000 row tables with virtual scrolling and column sort in under 16ms.
- 04Documentation site with search and versioning. MDX-based docs with full-text search backed by a ClickHouse trigram index. Version selector switches the entire documentation tree without a page reload. Build time for 400 pages: 45 seconds.
PROCESS
How we deliver
Every engagement follows the same three phases. No surprises, no scope creep.
Requirements + Component Architecture
We convert product requirements into a component tree, routing structure, and API contract. Accessibility requirements and responsive breakpoints are agreed upfront.
Build + Performance Validation
Components built with server-side rendering and progressive enhancement. Core Web Vitals, Lighthouse scores, and cross-browser behavior validated before staging.
Production Deploy + Code Handoff
Deployed to your hosting infrastructure with CI/CD pipeline, environment configs, and full codebase transfer. Your team can ship features from day one.
