Need someone to fix or take over
your Android or iOS app?
I’m Ramiz, a senior Android and iOS developer. I take over apps from agencies and previous developers, fix the crashes and store rejections that keep coming back, and get stuck releases shipped. Kotlin and Swift natively, plus Flutter and React Native.
Scope is agreed after a diagnostic. I won’t promise a fix before inspecting the codebase.
A few situations this fits.
If one or two of these sound familiar, a rescue engagement is probably the right shape of help.
You inherited a difficult codebase
An agency or a previous team handed over the app, and changing it safely is harder than it should be.
Releases are blocked or risky
Shipping has become slow, manual, or unpredictable, and every release carries more risk than the last.
Persistent failures keep returning
Crashes, ANRs, performance, authentication, integration, or critical workflow regressions resurface release after release.
You need temporary ownership
A permanent mobile hire is still in progress, and the app needs an experienced owner in the meantime.
It needs targeted work, not a rewrite
The codebase needs focused refactoring around real risk — not an automatic, expensive rewrite from scratch.
A staged path back to stability.
We agree the actual scope after the diagnostic. Not every engagement needs all three stages.
- Stage 01
Rescue diagnostic
Establish the symptoms, reproduce the critical failures, and inspect the architecture and release constraints. You get a prioritized recovery plan grounded in what the codebase actually does.
- Stage 02
Stabilization sprint
Address the highest-risk failures first, contain the fragile areas, and restore a safe, repeatable release path so the app can move again.
- Stage 03
Transition or ongoing ownership
Document the recovered system and hand it back cleanly, support the permanent team, or continue with an agreed scope — whichever fits your situation.
Relevant rescue and recovery work.
A short slice of inherited, refactored, and release-recovered apps — the same kind of work a rescue engagement involves.
Unified Remote
10M+ installs · 3× faster rendering · API upgrade
Inherited the Unified Remote Android & iOS apps from the outgoing team. Upgraded the aging codebase from min API 9 → 14 in under 3 months while removing dead and duplicated code. Eliminated UI jank via GPU and memory profiling and achieved 3× faster live-image rendering by moving bitmap uploads to the GPU on a background thread.

Jirah Parent
Unstable app takeover · UI-jank removal
Took over the unstable Jirah Parent app and eliminated UI jank in under 1 month through targeted profiling and render-pipeline fixes.

Yahoo Fantasy Sports
Crash & ANR reduction · MVP → MVVM refactor
Rebuilt the contests and lineups screens in the Daily Fantasy module, then led the MVP → MVVM refactor that lifted business logic into a real domain layer. Owned stability for Daily Fantasy and Core Fantasy — drove crash and ANR rates down release over release using Sentry, Embrace, and QA-filed Jira signal.

SKEDit
Broken integration recovery · CI/CD rebuild
Restored broken Telegram and WhatsApp scheduling integrations — the app's core value proposition — and resolved multiple message-delivery failure modes. Rebuilt a broken CI/CD pipeline and shipped 10+ production releases in 3 months, automating Play Store internal-testing deployments.

Principles for a rescue.
Diagnose before rewriting
Understand the real failure modes first. A rewrite is a decision earned by evidence, not a default.
Stabilize critical paths first
Protect the user journeys and the release pipeline that the business depends on before anything else.
Refactor around risk
Target the changes that reduce business and stability risk, instead of rewriting code that already works.
Leave it easier to own
Hand back a codebase and delivery process the next team can maintain — clearer, safer, and documented.
Before you hire someone to fix your app.
- Can you take over an app another developer or agency built?
- Yes. Unified Remote and Jirah Parent were both apps I took over from a previous team. The first step is getting the code, git history, signing keys, store accounts and secrets into your hands, then reading the codebase before changing it. App handover checklist.
- My app keeps crashing. Can you fix it without a rewrite?
- Usually, yes. I reproduce the top crashes and ANRs from your crash reports, fix the highest-impact ones first, and add tests so they stay fixed. At Yahoo Fantasy Sports I owned stability for two modules and brought crash and ANR rates down release over release. A rewrite is a decision for after the diagnostic, not before it. Stabilize before you rewrite.
- Can you get an app through App Store or Google Play review after a rejection?
- Yes. I read the rejection against the guideline it cites, change what the reviewer actually tested, and resubmit with notes that answer the finding. I have taken apps through Play Store review at Carewell and cleared an App Store Guideline 4.2.3(i) rejection on my own app. How a 4.2.3(i) rejection was cleared.
- Our app hasn't shipped an update in a year. Can you get releases moving again?
- Yes. A stalled app usually has an outdated SDK target, a broken build or CI pipeline, and expired signing or store setup. I fix those in that order and set up automated store deployment. At SKEDit I rebuilt a broken CI/CD pipeline and shipped 10+ production releases in 3 months. What breaks when an app stops shipping.
- Which technologies do you work with?
- Native Android in Kotlin and Java (Jetpack Compose, Coroutines, Room, WorkManager), native iOS in Swift (SwiftUI, UIKit), and cross-platform in Flutter and React Native. For AI features I built ping-ai-sdk (LLM integration, streaming, tool calling, on-device inference) and shipped it in my own apps LeadPing and AutoReplyPing.
- Do you work with teams in the US and Europe?
- Yes. I work remotely, and most of my clients have been in the US and Europe, including Yahoo Sports, Plume, Portal, Carewell and Unified Remote.
- How is a rescue priced?
- Scope and price are agreed after a short diagnostic, once I have seen the codebase. I don't quote a fix for an app I haven't inspected.
Tell me about the app.
Send a short note with the app, the symptom you’re seeing, who owns it now, and the outcome you want. I’ll come back with a read on scope and fit — a focused conversation, not an open-ended teardown.
