Your product already exists. Now something needs to work.
I step into existing web applications to investigate bugs, broken integrations, unfinished features and problems keeping the product from moving forward.
I diagnose first. I only take on what I can scope and deliver safely.
When it makes sense to call me
Something that worked stopped
A build, component, integration or flow started failing and nobody has found the cause yet.
The MVP is almost done — almost
The product was prototyped fast and now has bugs, incomplete flows or technical decisions that need organizing before launch.
Frontend and API aren't talking properly
Wrong data, inconsistent state, request errors, incomplete integration or unexpected behavior.
There's a feature stalled in the backlog
A well-scoped feature needs to ship without pulling the main team away for weeks.
An e-commerce store needs investigation
Especially in React, TypeScript and VTEX environments, where the problem may sit between interface, integration and platform behavior.
What I can take on
- React and Next.js
- TypeScript
- Node.js
- API integrations
- Bugs and regressions
- UI and responsiveness
- Small backend services
- VTEX IO and e-commerce
- Small automations
- Reading and reviewing existing code
- Projects started with AI tools that need human review
Not sure your problem fits here? Send me the context. I'd rather say “that's not mine” early than promise something I won't deliver well.
How the Rescue Sprint works
You show me the problem
A link, video, screenshots, a repository or a plain explanation.
I investigate
I map the affected flow, the code involved and the likely extent of the fix.
We lock the scope
We define exactly what's in and what's out — no timeline or price assumed before the analysis.
Implementation
Focused fixes that preserve the existing architecture and avoid needless rewrites.
Delivery
What was happening, what changed, how to validate — plus relevant risks or next steps.
Pricing
from R$1,500
The final price depends on the problem and the scope. Before any paid work, we align on exactly what will be delivered.
Very small problems may not justify a full sprint. Larger projects may need to be split into stages.
Why trust this
None of this is a promise — it's all inspectable:
An EPUB reader in the terminal, in Go, with testable sessions and real binary captures.
A fix accepted into someone else's open source project, by reading code I didn't write.
Day to day in a real e-commerce: TypeScript, React, Node and VTEX IO at Amara Net Zero.

Is something blocking your product?
Send me the context. If it's within what I can solve well, I'll tell you how I'd approach it. If not, I'll tell you that too.
