Next.js maintenance
Is your Next.js application already running, but bugs, updates, or technical debt are piling up? I help with maintenance, fixes, and safe further development, so the product becomes manageable again.
What problem does this solve?
Existing apps become fragile: deployments feel risky, small changes feel dangerous, and nobody dares touch the core. Meanwhile the business keeps asking for features.
Maintenance is about stability, updates, bug fixes, and clear priorities. Not cosmetic tweaks while the foundation is failing.
Handover issues often play a role too: the previous developer is gone, documentation is missing, or knowledge lives in one person's head. Good maintenance then starts with understanding what's actually running.
For pure performance and Core Web Vitals, there's a dedicated page. Here the focus is on keeping and improving the reliability of what's already there.
Who is this for?
- Companies with an existing Next.js or React application
- Teams without dedicated capacity for maintenance
- Product owners who want to tackle technical debt
- Organizations that want to take over or professionalize an application
- Teams stuck in 'hotfix after hotfix' without a plan
What I concretely do
- Bug fixes and stability improvements
- Dependency and framework updates
- Refactoring of difficult or risky parts
- Safer releases and CI/CD improvements
- Further development of existing features
- A short audit with a priority list when taking over a project
Approach
- 01
1. Technical scan
I review the codebase, errors, deployment, and risks. Not an endless audit, but a sharp diagnosis of what needs attention first.
- 02
2. Priorities
Together we determine what's urgent: stability, updates, or extensibility. So you're not working on cosmetics while production is on fire.
- 03
3. Targeted fixes
Clear steps, with an explanation of what changes. Where useful, with tests or monitoring so regressions become visible faster.
- 04
4. Further development or handover
After that, features on a more stable foundation, or a clean handover so your team can continue.

Example from practice
On existing platforms, I often help with a mix of bug fixes, technical debt, and fragile deployments. The goal isn't 'one more feature', but an application that can be developed further smoothly again, even if the original builder is no longer around.
