Web Applications

A website tells a story; a Web Application runs a business. While a standard site is mostly static content, a web app is an interactive engine that handles user authentication, complex data processing, and real-time updates.

At Neviox Digital, we build applications that act as the central nervous system for your operations. Whether it's a custom CRM, a booking engine, or a complex SaaS platform, we ensure the architecture is 'Headless' and decoupled, allowing for lightning-fast speeds and the ability to integrate with any external API (Stripe, ERPs, or AI agents).

We don't believe in legacy technology. Our engineering team in Croatia utilizes the world’s most advanced web stack to give you a competitive edge:

• Next.js & React: The gold standard for front-end performance. We utilize Server-Side Rendering (SSR) to ensure every page is indexed by Google instantly.
• Node.js/Nest.js & Drizzle: A robust backend capable of handling thousands of concurrent users with type-safe database management.
• Auth.js & Security: Enterprise-grade authentication and Role-Based Access Control (RBAC) to protect your proprietary data.
• PostgreSQL & Supabase: High-integrity data storage designed for complex relationships and scale.

Slow software is expensive software. We leverage Serverless Cloud Infrastructure (Vercel & AWS) to ensure your application performs consistently regardless of traffic volume.

By building 'Cloud-Native,' your application only uses the resources it needs. This means zero downtime during updates and a significant reduction in hosting costs. Our apps are optimized for Core Web Vitals, ensuring that Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS) scores are always in the 'Green' zone, which is critical for both user retention and SEO rankings.

Most developers treat SEO as an afterthought for web applications. We treat it as a core requirement. Using Next.js App Router, we ensure that even the most complex data-driven apps are fully crawlable by search engines.

We implement:

• Server-Side Rendering (SSR): Content is rendered on the server, not the browser, giving you an immediate SEO advantage.
• Dynamic Metadata: Every user-facing page is optimized with custom meta tags and JSON-LD schema.
• Edge Middleware: Personalized content delivered at the speed of a static site.

Custom software is a high-value asset. Our process in Croatia follows an Agile methodology, delivering a functional MVP (Minimum Viable Product) within weeks.

You maintain full ownership of the code and the intellectual property. By automating manual processes and consolidating data silos into one custom web app, our clients typically see a full return on investment through reduced labor hours and increased operational accuracy.
