Software maintenance and performance optimization for companies in Austria and the DACH region

LONI DIGITAL maintains and optimizes existing web apps and SaaS platforms for companies in Austria, Germany and Switzerland. We audit the code and infrastructure, fix whatever slows your product down or puts it at risk, and then keep looking after it. You reach your contacts in person in Austria, in German or English.

Who it is for

  • Companies whose app was built by another agency or a freelancer and now has no one to look after it
  • Small and mid-sized companies whose web app gets noticeably slower as more people use it
  • Start-ups whose product is growing faster than the infrastructure behind it
  • Businesses without an in-house IT team that want updates, backups and monitoring in reliable hands

What you get

  • A written audit with prioritized findings and concrete recommendations
  • Measurably faster pages and database queries, with a before-and-after comparison for every change
  • Security updates and up-to-date dependencies, from the framework to the server
  • Monitoring and regular backups, so outages are caught early and data can be restored
  • A maintenance arrangement that sets out the scope and response times in writing

How we keep your application fast and stable

  1. Audit and measure: Before changing anything, we analyze the code, database and infrastructure and record load times and error rates as a baseline.
  2. Prioritize: We rank the findings by risk, benefit and effort, and agree with you on the order, scope, timeline and budget.
  3. Fix and optimize: We close security gaps, speed up slow pages and queries, and prepare the infrastructure for more traffic. Every week you see what has improved, backed by measurements.
  4. Ongoing care: We keep your application up to date, monitor it and take care of backups, so small problems do not grow into big ones.

Typical problems we solve

  • Slow pages and poor Core Web Vitals that can cost you visitors and search rankings
  • Sluggish database queries that hold up lists, searches and reports
  • Outdated dependencies and security gaps in frameworks, libraries and on the server
  • Servers that do not scale with growing traffic and struggle when load peaks
  • Missing monitoring and backups, so customers notice outages before you do
  • Undocumented code that nobody wants to touch because any change might break something else

Technologies

On the frontend we work with TypeScript, React, Next.js and Astro, on the backend with Node.js or PHP and Laravel, and for data with PostgreSQL, MySQL, MongoDB and Supabase. Docker keeps deployments reproducible, we host on Hetzner servers in the EU, and Cloudflare handles fast delivery and extra protection. We measure before and after every change and show you the difference. If your application runs on a different stack, we will tell you honestly whether we are the right fit.

Maintenance with short paths

In maintenance, what matters is reaching the right people quickly. Your contacts are in Austria, and we are happy to go through audit results with you in person, in German or English. Our own development team in Leskovac, Serbia, looks after your application, and your questions go straight to the developers instead of into a support queue. You can find more on our page about working with us.

FAQ

Frequently asked questions

Do you take over applications built by other developers?

Yes. We always start with an audit of the code and infrastructure to see how the application is built and where the risks lie. Based on the results, you decide how to proceed, with us or without us.

What does an audit include, and what do I get at the end?

We review the code, architecture, database and servers, measure load times and Core Web Vitals, and look for outdated dependencies and security gaps. You get a written report that ranks every finding by urgency and effort, and we walk you through it in person or on a video call.

How is ongoing maintenance arranged and billed?

After a short intro call you get a fixed estimate or a clear range. A stable application mostly needs updates and monitoring, while a growing one also needs regular improvements, so we put the scope, response times and billing in writing before the work begins.

What happens in an emergency?

We define the process together before it is ever needed: what counts as an emergency, how you reach us and how quickly we respond. It is written into the maintenance arrangement, and we only commit to response times we can actually meet.
