About this Gig
Slow scrolling, delayed screens or unnecessary re-renders in your React Native app? I will profile a reproducible problem and help you improve the agreed frontend flow.
BASIC: profile one slow flow and provide findings with a prioritized action plan. This is a diagnostic package; code fixes are not included.
STANDARD: profile one flow and implement up to two agreed fixes.
PREMIUM: profile up to three flows and implement up to five agreed fixes.
Typical work includes list rendering, component re-renders, image loading and costly JavaScript work. Implementation packages include changed source code, a change summary and before/after checks under the same agreed device and test conditions.
Results depend on your app, device, data and backend. No fixed speed increase or score is guaranteed. Backend rewrites, major architecture changes, SDK upgrades and new features are separate scopes.
Send your source stack, affected flow, reproduction steps and target device before ordering. A reproducible baseline is required. Revisions cover the agreed findings or fixes. Cover artwork is a concept illustration.

FAQ
Does Basic include code changes?
No. Basic profiles one reproducible slow flow and delivers findings plus a prioritized plan. Standard and Premium include a bounded number of agreed frontend fixes.
Can you guarantee a speed improvement percentage?
No. Results depend on the app, hardware, data and backend. I compare the agreed measurements before and after changes under consistent test conditions and explain remaining bottlenecks.
What types of performance problems can you investigate?
Examples include slow lists, excessive component re-renders, heavy JavaScript work and image-loading delays. I review reproduction steps and the codebase before confirming scope.
Is backend performance included?
These packages focus on the React Native frontend. Slow server endpoints may be identified, but backend rewrites, infrastructure changes and database optimization require separate work.
What do I receive after optimization?
Implementation packages include changed source code, a change summary and before/after checks for the agreed flows. Basic provides the diagnostic findings and action plan only.
