FAQ

Frequently Asked Question - Java Development Company in the UK

❓ What kind of Java projects do you take on?

We usually work on mid- to large-scale systems. Devfan specialises in projects like complex back-ends, enterprise platforms, SaaS products, or high-traffic apps where stability and performance matter.

❓ Can you jump into an existing Java codebase? Even if it’s a mess?

Yes. Most of our clients bring us into live projects which are sometimes half-built. Devfan specialises in auditing legacy code, figuring out what’s going on, and cleaning it up without breaking related functionality. If the codebase is worth saving, we’ll work with it. If it’s not, we’ll tell you straight.

❓ How fast can you start?

For short-term dev support, we can usually plug a Java developer in within a week. If it’s a full build or rescue mission, we’ll estimate it out first, then give you a real start and finish date.

❓ Do you only work with Java?

No. Our developers work across the diverse stack of technologies and play nice with the rest of your tech.

❓ Can you help modernise our old Java app?

Yes. If your platform’s stuck on Java 8 with outdated libraries, we’ll help you upgrade without pulling the whole thing apart. If the architecture needs refactoring or containerisation, we’ll take that on too. You’ll end up with a faster, safer, and easier to maintain digital product.

❓ What if we need to scale up or down mid-project?

You can. If you need more Java devs, we’ve got them. If you need to pause or slow things down, we’ll work with you. It’s your roadmap: Devfan is here to support it, not control it.
