Hamza Bilal Gaya

I’m a Senior Flutter Developer with over 6 years of hands-on experience architecture-level building responsive, scalable, and high-performance mobile applications across ride-hailing, streaming, travel, security, and fintech.

I’ve engineered and shipped products for startups and companies across Pakistan, the UK, and the Gulf—leading teams, modernizing legacy codebases, and delivering production-grade releases under aggressive timelines.

Core Competencies & Services:

• End-to-End Mobile App Development: From clean architecture setup to Play Store / App Store deployment.
• Performance Tuning & Codebase Refactoring: Fixing memory leaks, optimizing UI frame rates, and restructuring legacy code into BLoC/Cubit pattern.
• API & Backend Integration: REST, Firebase, WebSockets, deep linking, and third-party SDKs.
• AI-Assisted Workflow & Automation: Integrating modern AI tools (Claude Code, GitHub Copilot) and n8n backend automation into the development pipeline to accelerate shipping times and handle complex API orchestrations.

Parallel to full-stack Flutter delivery, I mentor and train junior developers, guiding them through clean code principles, state management, and real-world app deployment.
