Mobile Feature Work
Implement scoped features inside existing Flutter apps with attention to real-world product constraints.
New apps built in phases, plus feature work, bug fixing, and release support inside products you already run. Clear limits, no agency overhead.
Good fit if
You need help inside an existing app or product, not a big greenfield agency process.
You want direct communication with the engineer doing the work.
You want bounded support that fits a part-time async model.
Services
Implement scoped features inside existing Flutter apps with attention to real-world product constraints.
Resolve product bugs, clean up rough edges, and improve release confidence before shipping.
Support app store submission, build/signing issues, TestFlight or Play Console handling, and hotfix follow-up when scope is clear.
Handle REST integration, Laravel, Next.js, and delivery support work that helps the product move forward across mobile and web.
Availability & capability
Availability
Best suited to 8-16 hours per month, with 16-20 as the practical ceiling.
Async-first support; calls are limited and messages are preferred.
Best run as one anchor client or one light retainer plus a small overflow client.
Capability
Core delivery
Scoped carefully
Packages
Packages reserve a block of engineering time for the month. Larger or less-defined features are quoted separately based on scope.
For bug fixes, scoped implementation, and small release-related work inside an existing Flutter product.
For teams that need recurring help shipping inside an existing product, without the noise of a heavy freelance arrangement.
For one primary client who needs consistent help each month and can work well in an async-first setup.
How to choose
Choose Ad Hoc Support if
You have a few small fixes, one-off tasks, or light release-related work and do not need ongoing monthly coverage.
Choose Monthly Support if
You expect recurring work each month and want a stable block for features, bugs, and follow-up tasks.
Choose Primary Retainer if
You want one consistent part-time engineering partner and the work fits within a realistic 16-hour monthly ceiling.
New builds
Every build starts with paid discovery, which produces a written scope and a real estimate. Nothing fixed-price is agreed before that. Each sprint is paid and delivered on its own, so the commitment is one phase rather than a whole project.
A paid session that produces a written scope and a real estimate. The only thing quoted before the work is understood.
Any new app, and any existing-app work too vague to phase yet.
The smallest bounded piece of a new build, priced fixed against the discovery document.
A first sprint with someone new, where both sides want a small commitment before a bigger one.
A full phase of a new build, priced fixed against the discovery document.
Clients who have completed a sprint already and know how the work runs.
A larger phase for work that does not divide sensibly into forty hours.
Established clients with a phase that genuinely needs the extra room.
This is production work. Existing codebases, payments and integrations, release and app store cycles, and new builds delivered a phase at a time.
Billing
Monthly packages reserve a block of engineering time for that month. They are not pay-only-for-used-time bundles.
Up to 25% of unused hours, capped at 4 hours, carry into the following month. Anything above that expires at month end.
Bug fixes, smaller features, release work, and follow-up tasks can be handled within the package if the scope fits the included hours.
If the requested feature is bigger, less defined, or likely to exceed the included hours, it will usually be quoted separately based on scope and estimated man-hours.
Simple billing rules
Monthly packages reserve a block of engineering time for the month.
Up to 25% of unused hours (maximum 4 hours) carry into the next month; the rest expires at month end.
If work goes beyond the included hours, extra time is billed at the package overage rate.
Bigger feature work may be quoted separately based on feature scope and estimated man-hours.
Process
Client shares the product context, target platform, timeline, and expected monthly hours.
A package or hourly arrangement is chosen based on certainty, urgency, and whether the work fits the available monthly bandwidth.
Work is shipped in bounded chunks so there is no confusion around what was done and what remains.
Frequently asked
Small product teams, founders, or former employers with an existing mobile product and some adjacent web/backend needs that need steady implementation support.
No. The package is usually picked after scope, urgency, and expected monthly hours are clear.
Yes. Small one-off work fits the ad hoc model. Repeating work is usually better as a light monthly package.
Monthly packages reserve engineering time for that month. Up to 25% of unused hours, capped at 4 hours, carry into the next month. Anything beyond that expires at month end.
Smaller features can be handled within package hours if the scope fits. Larger or less-defined feature work is usually quoted separately based on feature scope and estimated man-hours.
