I help startups and product teams fix unstable mobile apps, improve performance, and scale production systems, including apps with AI features, without breaking existing functionality. Clients usually come to me when their app is already live but facing issues that impact users, stability, or revenue. Common problems I solve: • Frequent crashes, ANRs, and unpredictable app behavior • Slow performance, memory leaks, and poor responsiveness • Payment failures or unreliable API integrations • AI features (chat, recommendations, automation) not working reliably • New features breaking existing functionality • Legacy code that is difficult and risky to modify Results I’ve delivered: • Reduced app crash rates by up to 40% by identifying and fixing root causes • Improved app performance and load times by optimizing memory usage and API handling • Stabilized production apps used by thousands of active users • Resolved critical API, payment, and backend integration issues • Integrated and improved AI-based features within mobile apps What I work on: • Native iOS & Android applications in production • Flutter (cross-platform) mobile apps • AI-powered features (chat, recommendations, automation workflows) • Payment gateway integrations and complex API workflows • Debugging crashes, ANRs, memory issues, and performance bottlenecks • Code refactoring, architecture improvements, and long-term maintainability • App Store & Play Store submissions, updates, and compliance How I work: • I solve root problems, not temporary fixes • I prioritize stability before adding new features • I write clean, maintainable, and scalable code • I leverage modern AI tools to speed up development, debugging, and testing while maintaining high code quality • I communicate clearly and take ownership of delivery • I ensure new changes do not break existing functionality CTA: If your app is facing crashes, performance issues, or unreliable features, send me a quick message with the details. I’ll review your app and suggest the fastest, safest way to fix and improve it.
