Common issues I solve

If your app feels unstable or inconsistent, these are the most frequent patterns I fix first.

  • Some features do not work as expected
  • Parts of the interface feel broken or inconsistent
  • The application is slow or unresponsive
  • Small issues keep piling up (UI, text, responsiveness)
  • Things just do not behave the way they should

Rescue Sprint

A focused engagement to fix the most important issues in your application - from critical bugs to small but frustrating UI and usability problems.

Typically focused on a limited scope of high-impact fixes that can be completed within a few days of work.

What I do

  • ▸ Fix broken features and visible issues
  • ▸ Improve UI consistency and responsiveness
  • ▸ Resolve performance bottlenecks
  • ▸ Identify deeper problems that may cause future issues

Outcome

Your application works more reliably, feels smoother, and stops getting in your way.

Approach

No full rewrite. No unnecessary complexity. Just targeted fixes where they matter most.

How it works

1. Quick form

You describe your problem and provide basic details about your application.

2. Initial review

I review your case and check if I can help.

3. Scope & estimate

I propose what to fix first, with a clear scope, timeline, and price.

4. Short call (if needed)

We clarify details and confirm the scope.

5. Fixes

I implement targeted improvements - from bugs to UI and performance.

6. Handover

You get a more stable application.

Tested

Changes are tested before deployment

✓

Rollback safe

Every change can be safely rolled back

✓

No risky rewrites

No risky rewrites or unnecessary changes

If your project does not have proper setup (repository, staging), I can help establish a safe workflow first.

You do not need a new team. You need your application to work.

I fix real problems in existing JavaScript applications - without rewrites or unnecessary complexity.

1.

Clear communication

2.

Focus on visible results

3.

Small, safe changes

4.

Respect for your existing system

This is targeted help when your application needs to work again.

Built for real-world JavaScript applications

I work with modern JavaScript/TypeScript applications across frontend and backend.

React, Next.js Angular Node.js (APIs, backend services) Vite / modern frontend tooling

If your application is built with JavaScript or TypeScript - I can work with it.

You do not need a perfect setup - I work with existing, often messy applications.

Frequently Asked Questions

Do I need access to the source code?
Yes - access to the code repository is required to safely fix issues. If you do not have it, I can help you set it up first.
What if I do not have a staging environment?
It is recommended, but not always required. If needed, I can help establish a safe workflow before making changes.
How quickly can you start?
Usually within a few days, depending on availability and project scope.
How is pricing determined?
Pricing depends on the scope and complexity of the issue. After the initial review, you receive a clear estimate before any work begins.
Can you fix small issues only?
Yes - small fixes (UI, text, responsiveness) are a core part of the service.
Will this break my application?
No - all changes are done in a controlled, safe way with rollback options.
Do you offer long-term support?
Yes - after initial fixes, ongoing support is available to keep your application stable.
