Project details

Slow loading times and lag kill user retention. I will execute a professional, AI-assisted performance audit and guarantee a measurable speed boost for your mobile app.

If your app is buggy, slow, or draining batteries, you are losing users and revenue. I specialize in using senior-level debugging and Observability methods to pinpoint the exact technical bottleneck—be it slow backend traces, inefficient data fetching, or memory leaks—that are destroying your user experience.

I will guarantee that:
 • Speed is Restored: I will resolve the root causes of slow load times and frame rate drops, ensuring a smoother, faster app that delights your users.
 • Stability is Solid: I will address the architectural issues that lead to crashes and Application Not Responding (ANR) errors, restoring user confidence.
 • Efficiency is Improved: I will optimize background processes and code execution to drastically reduce battery consumption, a core modern feature.

Stop guessing what's wrong with your app. I will provide the definitive answer and execute the clean code fix needed to guarantee high performance.

Mobile App Configuration & Map Issue Fix for iOS/Android App (iProwide) Excellent Developer – Flutter, App Store, Google Play, Stripe & Hosting Optimization
I worked with Mirza on a mobile app that was being removed Apple Store due to several compliance issues. He quickly identified and fixed all the problems, upgraded the app to the latest Flutter version, and reconfigured everything to ensure a smooth and stable release.

He also handled changes to Stripe integration, ensuring it met the latest requirements, and proactively suggested a more efficient and affordable hosting solution, which significantly reduced my backend costs.

His communication was clear, consistent, and professional throughout the project. He worked independently, delivered high-quality code, and always kept me informed.

If you're looking for a skilled, reliable, and forward-thinking developer, especially for Mobile Projects or App Store or Google Play compliance, I highly recommend Mirza. I’m very satisfied with the results and look forward to working together again.

Mobile App Developer for Booksummary App I hired Mirza S. to develop a cross-platform mobile app for our book summary service, and I couldn’t be more pleased with the outcome. The project required building a dynamic, user-friendly application with complex features such as user authentication, categorized book browsing, advanced search functionality, and a content management console. Despite some technical challenges along the way, Mirza handled everything with professionalism and confidence.
He was consistently communicative, keeping me informed at every stage of development. What stood out most was his responsiveness and willingness to go the extra mile — not just delivering on the requirements, but also proactively improving the app in ways that enhanced user experience and performance.
The final product is now live on both the App Store and Google Play, and it reflects Mirza’s dedication to quality. I highly recommend him for any mobile app development project and look forward to working with him again in the future.

Senior Mobile Engineer | Flutter + iOS/Android | Stripe/IAP | RAG AI

Mandi Bahauddin, Pakistan - 8:34 am local time
I build and ship mobile apps that pass App Store / Play review.
I also fix crashes, payment issues (Stripe/IAP), and add AI chat using your data (RAG).

I’m a senior mobile engineer (Flutter + iOS + Android). I help teams ship, fix, and scale apps without drama: store rejections, payments, performance, and “hard” features like maps and AI chat.

𝐖𝐡𝐚𝐭 𝐈 𝐝𝐨 (𝐟𝐚𝐬𝐭 + 𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧-𝐫𝐞𝐚𝐝𝐲)
• App Store / Google Play submissions: rejection fixes, privacy/metadata, resubmission support
• Payments: Stripe + In-App Purchases (subs, receipts, server webhooks)
• Flutter builds + rescue: bugs, architecture cleanup, performance, CI/CD (Fastlane)
• AI in apps: RAG chat, tool/function calls, vector DB, logging + feedback
• Firebase + push: Auth, Firestore, FCM/APNs, deep links
• Maps + location: Google Maps/Mapbox, background tracking, offline basics

𝐇𝐨𝐰 𝐈 𝐰𝐨𝐫𝐤
Clear scope → weekly checkpoints → clean PRs → docs + handover. You’ll always know what’s done, what’s next, and what’s blocked.

𝐇𝐢𝐕𝐄 𝐂𝐨𝐝𝐢𝐧𝐠 (𝐦𝐲 𝐝𝐞𝐥𝐢𝐯𝐞𝐫𝐲 𝐦𝐨𝐝𝐞𝐥)
Human Engineers + Agentic AI (Cursor, Claude Code, Codex) = 10× development speed without losing code quality or control. I also leverage modern “vibe coding” tools (FlutterFlow, v0, Bolt, Lovable, Tempo Lab) for fast MVPs.

𝐖𝐡𝐚𝐭 𝐭𝐨 𝐬𝐞𝐧𝐝
Share your store link/TestFlight/Play Console, goal, and any crash/rejection notes. I’ll reply with a simple plan and timeline.

Steps for completing your project

After purchasing the project, send requirements so Mirza can start the project.

Delivery time starts when Mirza receives requirements from you.

Mirza works on your project following the steps below.

Revisions may occur after the delivery date.

Metric Ingestion & Analysis

I will ingest and analyze your existing performance data (crashes, ANRs, load times) to identify the specific code area causing the slowdown.

Root Cause Pinpointing

I will use code review and debugging tools to isolate the exact line(s) of code or API calls creating the performance bottleneck.

Review the work, release payment, and leave feedback to Mirza.
