I work with enterprises and product companies to design and build stable, scalable, and maintainable mobile platforms using Flutter, backed by clean architecture, SDK-first design, and production-ready AI integrations.
With 6,000+ hours on Upwork, $100K+ in enterprise engagements, and Top Rated Plus status, I focus on long-term mobile systems. My role often extends beyond coding into technical architecture, platform strategy, and risk mitigation for mobile products used by thousands of users.
How I work :
• Design SDK-first mobile architectures where business logic, APIs, and AI capabilities live in versioned, reusable modules
• Build Flutter applications that integrate cleanly with existing enterprise backends and internal systems
• Ensure backward compatibility, upgrade paths, and controlled releases
• Collaborate with product managers, backend teams, and QA to align mobile delivery with enterprise standards
Core Expertise:
• Enterprise Flutter App Development (iOS & Android, single codebase)
• Mobile SDK & Plugin Development (Flutter SDKs, internal platforms, API wrappers)
• AI Integration at Platform Level (OpenAI, intelligent workflows, automation)
• Modular & Clean Architecture (scalable, testable, maintainable)
• Backend Integration (Firebase, Supabase, REST, GraphQL, internal APIs)
• Authentication, Payments, Subscriptions & Access Control
• Performance Optimization & Reliability
• Testing Strategy, QA Coordination & Release Management
• App Store & Play Store Enterprise Deployment
AI for Enterprise Mobile Products
I implement controlled, production-grade AI, embedded at the platform or SDK layer — enabling features such as automated assistance, intelligent recommendations, guided workflows, and analytics-driven user experiences. All AI integrations are designed with cost management, latency control, and data boundaries in mind.
If your organization needs a senior Flutter architect who understands enterprise constraints, scalability, and long-term ownership, I’m open to structured engagements and contract-to-hire discussions.
