Web applications

Custom web applications and digital tools

When off-the-shelf systems are no longer enough. We design and develop lightning-fast web applications, customer portals and SaaS platforms that digitalize your unique business processes.

Discuss your project with us

Do you adapt your business to the software, instead of the other way around?

Many companies reach a tipping point where ready-made licensed programs and standard software (SaaS) start to slow growth. Perhaps you lack a specific feature, are forced to pay expensive license fees for features you do not use, or your system is so complex that new hires need weeks of training.

When standard solutions do not support your unique business model, staff are forced to build their own "creative" solutions in Excel to make everyday work function. You do not need another subscription – you need your own, tailor-made web-based tool built exactly around how you actually work.

Build your own platform with modern architecture

At Y10K we build advanced, cloud-based web applications that solve complex problems. Whether you want to build a portal for your customers or an internal calculation tool, we deliver a truly world-class product.

  • Customer portals & "My pages"

    We build secure login portals where your B2B customers can manage their own orders, view history, download contracts and interact with your company.

  • SaaS platform development

    Do you have a brilliant idea for a new software product? We act as your external tech department and build your MVP (Minimum Viable Product) ready for the market.

  • Custom internal tools

    We digitalize your unique processes – from custom booking systems and project planning tools to advanced quote calculators.

  • Unbeatable performance (React/Next.js)

    The applications are built with modern frameworks. This gives the user a lightning-fast, app-like experience straight in the browser, without having to download anything from the App Store.

From first sketch to finished software

  1. Requirements & UX prototype

    We break your idea down into concrete features. We create clickable prototypes (UX design) so you can test how the application feels before we write a single line of code.

  2. Architecture & Development

    We build the system with a robust backend (C#/.NET) for secure data handling and a fast frontend (React/Next.js) for a superior user experience.

  3. QA, Deployment & Maintenance

    After rigorous security and performance tests we roll out the application in a scalable cloud environment (Vercel/Azure) and support you with ongoing updates.

Frequently asked questions about web applications

A website is usually static and informative (like a digital shop window). A web application is interactive and data-driven – it is a tool where the user logs in, manipulates data and performs specific tasks (like Gmail, Trello or your existing CRM system).

Yes, absolutely. Once the project is paid for and delivered, all intellectual property rights and the source code pass to you. You are not locked in with us, even though we are happy to stay on as your technical maintenance partner.

Security is built in from day one. We use modern encryption, secure API calls, strict role-based access control (RBAC) and established authentication protocols to make sure your data is protected against intrusion.
