FAQ
What stack do you support?
Primarily TypeScript/Node.js, Python, React/SolidJS, and mobile (Flutter/React Native). Other stacks evaluated on request — describe it in your initial message.
How do I share repo access?
GitHub: add @wUltimaProject as read-only collaborator. GitLab/Bitbucket: same process. NDA available before access on request.
What if 72h aren't enough?
I'll flag within the first 24h if the bug is more complex than expected. I'll propose an agreed scope update or full refund — no extra charge without consent.
Is the fix tested?
Yes. Every Bug Sprint includes an automated test covering the resolved case. If there's no existing test suite, I add the minimum test to prevent regression.
I have multiple bugs. Is this still worth it?
Bug Sprint is optimised for a single isolated bug. For broader scope consider Feature Sprint (€840, 5 days). Send me the scope →
Can I have a call before starting?
Yes, for complex scope a 15-min call before confirming is totally fine. Contact me via form and we'll set it up.
