Web platforms built for speed and scale.

From internal tools to customer-facing platforms serving millions. SSR, edge computing, progressive enhancement, and Core Web Vitals that actually pass. Fast for users, maintainable for teams, ready for the scale you'll hit next year.

What we build

Web platforms done right.

Next.js & React applications

Production-grade Next.js apps with App Router, React Server Components, and streaming. We build web platforms that feel instant — regardless of device or connection.

Server-side rendering

SSR, SSG, ISR — the right rendering strategy for every page. SEO-optimized, cacheable at the edge, and fast for first-time visitors and returning users alike.

Performance optimization

Core Web Vitals that pass. Code splitting, lazy loading, image optimization, font subsetting. We hunt milliseconds because users notice.

Progressive web apps

Offline-first architectures with service workers, push notifications, and installable experiences. Web apps that feel native — without the app store overhead.

Micro-frontends

Large-scale web platforms with independent team ownership. Module federation, design system sharing, and independent deployment pipelines for each domain.

SEO & accessibility

Semantic HTML, structured data, WCAG 2.1 AA compliance. We build web platforms that search engines love and every user can access — including those with disabilities.

Sound familiar?

Web problems we solve every month.

Our site takes 8 seconds to load. Google Analytics shows most users bounce before it renders.

We rebuild with SSR, aggressive code splitting, and edge caching. LCP drops to under 2 seconds. Bounce rate typically improves 40-60% in the first month.

Our React SPA got huge and now every feature update takes weeks because of regressions.

We introduce proper architecture — feature boundaries, shared UI library, comprehensive testing. Deploy cadence goes from monthly to daily, regressions drop 80%.

We need to launch in 3 countries with different languages, currencies, and compliance rules.

We build a localization-first architecture — i18n routing, locale-aware SSR, regional data residency. Launch in all 3 countries simultaneously, add a 4th in weeks.
