Hire Svelte Developers for Performance-Critical Frontends, SvelteKit Full-Stack Apps and Content Platforms

Build full-stack applications where the frontend and backend share the same codebase, deployment pipeline, and data-fetching conventions. The problem with separate frontend/backend repos is synchronization overhead: two deployment processes, two sets of type definitions, two teams responsible for the API contract. SvelteKit's server functions, form actions, and API routes let one developer own the complete request path from database to rendered HTML. We implement load functions for server-side data fetching, progressive enhancement with form actions that work without JavaScript, and adapter-based deployment to Node.js, Vercel, or Cloudflare Workers. One codebase. One deployment. Full-stack ownership.

Migrate performance-bottlenecked React or Vue applications to Svelte without a big-bang rewrite. Your React app works, but the bundle has grown to 1.2MB, Lighthouse scores have dropped below 70, and every new feature adds another 20KB. A full rewrite is too risky and too slow. We use the strangler fig pattern: replace high-traffic components with Svelte equivalents first, measure the performance delta, and migrate incrementally. Your existing components stay live throughout. We write compatibility layers where necessary and document the migration path clearly. No downtime. No surprises.

Build analytics dashboards where data updates continuously, components re-render efficiently, and the UI stays responsive under high data volume. The problem with React-based dashboards at scale is re-render cascades: a single store update re-renders the entire component tree unless you wrap everything in memo and useMemo. Svelte's granular reactivity means only the components that depend on changed state re-render. Always. We implement WebSocket connections using Svelte stores, chart components using D3 or Chart.js with Svelte bindings, and virtual scrolling for large datasets. Your dashboard handles 10,000 rows without a frame drop.

Build e-commerce frontends where page load time directly maps to revenue. The data is not new: a 100ms increase in page load time correlates with a 1% drop in conversion rate (Deloitte, 2020). Your current Shopify theme or React storefront ships 400KB of JavaScript before the first product image renders. We build SvelteKit-powered storefronts with partial hydration, image optimization pipelines, and edge-cached pages that deliver first contentful paint in under 500ms. We integrate with Shopify Storefront API, Stripe, and headless CMS platforms. Every millisecond counts. We measure it.

Build internal dashboards, admin portals, and operational tools that your team uses every day and that need to load fast even on a corporate VPN. Internal tools are often the last to get performance attention and the first to accumulate technical debt. We build Svelte-based admin portals with role-based access control, complex form workflows, and large data table handling. Svelte's minimal runtime means your tool works even on underpowered corporate hardware. We use SvelteKit's form actions for progressive enhancement so the tool works even if someone has JavaScript disabled. No vendor lock-in. Your team owns the code.

Build interfaces that consume AI APIs and stream responses to users in real time. The technical challenge is not AI itself but the frontend that makes AI useful: streaming text updates, optimistic UI states, error recovery when the API times out, and managing the cost of re-renders when content arrives in 50-byte chunks. We implement Server-Sent Events (SSE) for AI streaming using SvelteKit's streaming responses, writable Svelte stores for real-time state, and typed API clients using OpenAI SDK or Anthropic SDK. Your AI feature ships with a UX that does not feel like an afterthought.

Build reusable Svelte components that integrate into existing non-Svelte applications without framework conflicts. Your platform runs on React, Angular, or a legacy jQuery codebase. You want to introduce Svelte for new features without migrating the whole platform. Svelte compiles to standard Web Components. It does not require a global runtime. One Svelte component can embed in a React app, an Angular app, and a plain HTML page with the same compiled output. We design your component system with clear API contracts, Shadow DOM isolation where needed, and Storybook documentation. Your next feature ships in Svelte. The existing platform does not notice.
