Fixed-scope Android engineering

One stubborn Android issue.
Fixed in five business days.

A deliberately narrow offer

Built for problems that need senior attention—not a long procurement cycle.

The sprint works best when the issue is meaningful, reproducible enough to investigate, and isolated to the Android application.

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

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.

  1. 01

    Submit the issue

    Share the app, symptoms, business impact, and any useful links. I reply within one business day.

  2. 02

    Qualification call

    We use a focused 30-minute call to inspect the context, clarify dependencies, and decide whether the sprint is a fit. An NDA can be signed before repository access.

  3. 03

    Written scope

    You receive the issue definition, acceptance criteria, required access, exclusions, and delivery assumptions. You approve the scope before paying.

  4. 04

    Five-day sprint

    The clock starts after written approval, payment, complete access, and clarified questions. I diagnose, implement, and validate the agreed fix.

  5. 05

    PR and revision

    You receive the pull request or patch with technical context and validation steps. One scoped change request is included within the next business day.

What you receive

A usable engineering outcome—not a vague audit.

The primary deliverable is working Android code prepared for your normal review process. Documentation exists to make the change easier to understand, test, and maintain.

  • 01
    Diagnosis summary

    Symptoms, likely root cause, assumptions, and relevant technical constraints.

  • 02
    One pull request or patch

    Issue found, implementation, reproduction notes when applicable, and documentation.

  • 03
    Validation evidence

    Unit tests when practical and manual verification steps appropriate to the issue.

  • 04
    Useful follow-up findings

    A prioritized backlog of adjacent issues or improvements discovered during the sprint, when relevant.

  • 05
    One scoped revision

    One consolidated change request related to the agreed acceptance criteria, delivered within one business day.

Lifecycle failures

Intermittent loading, stale callbacks, recreation issues, and navigation-dependent failures that disappear during casual testing.

Memory and performance

Retained fragments, leaking observers, repeated map initialization, main-thread pressure, and inefficient media or data work.

Integration gaps

Push notifications, maps, analytics, SDK configuration, permissions, Gradle changes, and version-specific Android behavior.

Simple commercial model

A fixed price for one agreed outcome.

There is no hourly meter and no surprise expansion. If the request does not fit the sprint, you will know before payment—or receive a separate quote only when deeper investigation reveals a larger dependency.

Android Rescue Sprint

US$499

single payment

  • One approved Android issue
  • Five-business-day implementation window
  • Review-ready pull request or patch
  • Technical diagnosis and validation notes
  • One scoped revision
  • Full refund plus diagnosis if hidden constraints make the approved fix infeasible
Check if your issue fits

The sprint does not guarantee that a client will merge, release, or accept code outside the agreed criteria. Larger work requires a separate written proposal.

Who does the work

Android App Hero is a focused service by Andrés Garrido.

I am a Chile-based senior Android engineer who has worked professionally in Android development since 2013. You work directly with me—from the first technical call through the final pull request.

International clients can contract remotely and pay in US dollars through agreed business payment methods such as Wise, PayPal, or Payoneer. Invoices and contracting details are confirmed before the sprint begins.

Start with the problem

Tell me what is breaking.

Provide enough context to determine whether the issue fits the sprint. After submission, you can choose a time for the qualification call.

One-business-day reply
No payment or repository access is required to submit.

NDA-friendly workflow
Sensitive implementation details can wait until legal access is in place.

No marketing list
Your submission is used to evaluate and respond to this request.

Straight answers

Frequently asked questions

What does “production-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.

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.
