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.
