A specialist intervention, not staff augmentation
Remove the issue without creating another hiring or management problem.
Android App Hero is designed for product teams that already know the problem matters but cannot justify a new hire, a broad agency engagement, or another open-ended investigation.
Buy an outcome, not hours
The issue, acceptance criteria, access, exclusions, fee, and delivery conditions are agreed before payment.
Reduce decision risk
The initial fit review is free. If a hidden constraint makes the approved Android-side resolution infeasible, the sprint fee is refunded and you keep the diagnosis.
A deliberately narrow offer
Best for Android issues with visible product or engineering impact.
The strongest fit is a meaningful problem affecting release confidence, Play Store feedback, support volume, retention, or recurring engineering time—and isolated enough to solve as one approved Android engagement.
Good fit
Clear Android problems with bounded impact
- Crashes with a useful signal or reproduction path
- Memory leaks and retained screens
- Slow screens, jank, or wasteful app-side work
- Navigation and lifecycle failures
- Google Maps or Mapbox behavior
- Push notification integration problems
- Focused UI/UX implementation improvements
- General Android bugs of low-to-medium complexity
- Technical causes behind repeated Play Store complaints
- One recurring issue consuming support or engineering time
Not this sprint
Work that needs a different engagement
- ANR investigations without a strong diagnostic signal
- Issues that require unknown backend or infrastructure changes
- Major SDK or dependency migrations
- Large new features or multi-screen implementations
- Architecture rewrites or broad refactoring programs
- Device-fleet edge cases that cannot be reasonably reproduced
If your request is larger, you still receive a clear answer. I may propose a separate scope and quote, but no extra work starts without your approval.
A controlled workflow
Know what is being fixed before the clock starts.
The process protects both sides from vague bug reports, missing access, hidden backend dependencies, and endless review cycles.

Evidence of how difficult issues are approached.
These anonymized engineering case studies focus on the symptom, investigation, root cause, implementation, and validation. They are not claims that every issue will have the same outcome.

Intermittent map loading after repeated navigation
A screen worked normally until users repeatedly opened a detail view and returned. The loading indicator could remain indefinitely while the map failed to complete its normal sequence.

Reducing oversized Android video exports
A Media3 migration produced a one-minute video around 70.5 MB. The export path was reworked to preserve the required behavior while reducing output to about 15.6 MB in the tested scenario.

Stopping a retained map screen and repeated recreation
Repeated detail navigation retained screen work beyond the intended lifecycle and contributed to map recreation, memory pressure, and inconsistent UI recovery.

Android Hero Sprint
US$2,500
fixed fee for one approved issue
- One approved, bounded Android issue
- Five-business-day delivery window
- Diagnosis, implementation, and validation
- Review-ready pull request or clean patch
- Technical handoff and one scoped revision
- Full refund plus diagnosis if hidden constraints make the approved Android resolution infeasible
Scope is approved before payment. Larger or unsuitable work requires a separate written proposal. The sprint does not guarantee merge, release, store approval, or outcomes outside the accepted criteria.
The engineer behind the sprint
Direct senior ownership from diagnosis to handoff.
Android App Hero is delivered directly by Andrés Garrido, a senior Android engineer working professionally on Android products since 2013. There is no sales-to-junior handoff: the person qualifying the issue is the person investigating and implementing it.
Public GitHub work is useful as supporting technical evidence, while the strongest proof comes from concrete production problem patterns and documented engineering case studies.

Frequently asked questions
What does “review-ready pull request” mean?
It means code prepared for your normal engineering review process, aligned with the agreed acceptance criteria and the repository conventions visible during the sprint. It includes a clear description and reasonable validation evidence. It does not guarantee that your team will merge, release, or accept requests outside the agreed scope.
Why use this instead of assigning the issue to our existing team?
The sprint is useful when the problem matters but repeatedly loses priority to roadmap work, needs focused Android expertise, or is consuming more investigation time than the team can justify. It is not intended to replace a healthy internal team; it removes one bounded issue without adding permanent headcount or an open-ended consulting commitment.
Why fixed price instead of hourly billing?
The buyer should know the commercial commitment before work begins. The written scope defines the issue, acceptance criteria, dependencies, exclusions, fee, and start conditions. If the problem cannot be bounded responsibly, it is not accepted as a standard sprint.
What if the issue appears to have been resolved in a recent release?
No sprint is recommended merely to create work. I review the current evidence first. If the problem is no longer reproducible or there is not enough signal to justify a paid engagement, I will say so before payment.
Exactly when do the five business days begin?
After the written scope is accepted, payment is received, all required repository and environment access is working, and the questions identified during qualification are answered. Delays caused by missing access or client-side dependencies pause the timeline.
What happens if the issue requires backend changes?
Known backend dependencies are excluded before payment. If a hidden dependency makes the agreed Android fix infeasible, you receive a full refund, a diagnosis summary, and—when useful—an optional separate implementation plan or quote.
What if our team requests changes to the pull request?
One consolidated revision related to the agreed acceptance criteria is included. It is delivered within one business day after receiving a clear review request. New requirements, unrelated refactoring, preference changes, or expanded scope require a separate agreement.
Can you sign an NDA and work with restricted repositories?
Yes. An NDA can be completed before sensitive access is shared. When direct repository access is not possible, I can work from an approved reproduction project and provide a patch or diff, subject to the technical constraints of the issue.
Can a company outside Chile hire you?
Yes. The service is designed for remote B2B work with English-speaking companies across the Americas and Europe. Contracting, invoicing, and the agreed international payment method are confirmed before the sprint starts.
Do you guarantee a Play Store rating increase?
No. The sprint can address a specific technical issue associated with user complaints, but ratings, retention, release approval, and business outcomes depend on factors outside a single code change.
