$200K+ earned | 345+ apps shipped | App Store submission expert | Top Rated | 8+ years
Senior Mobile App Developer specializing in iOS & Android apps built with Flutter, React Native, Swift, and Kotlin — now AI-accelerated with Cursor AI, Lovable, Replit, and Base44 for 3x faster MVP delivery.
Over the past eight years I've shipped 345+ production apps on the App Store and Google Play — native iOS, native Android, and cross-platform builds in Flutter and React Native. Today, I combine that senior engineering foundation with modern AI development tools to deliver faster, cleaner, and more scalable mobile products than traditional workflows allow.
WHAT I BUILD
Native iOS applications — Swift, SwiftUI, Objective-C, Xcode
Native Android applications — Kotlin, Java, Android Studio
Cross-platform applications — Flutter, Dart, React Native, Expo
AI-integrated mobile apps — OpenAI, Claude, on-device ML, LLM workflows
Full-stack mobile products — frontend, backend, auth, payments, deployment
MVP sprints — idea to working app in 3 to 4 weeks
Long-term engineering partnerships — v2, scaling, refactors, ongoing features
WHY CLIENTS HIRE ME
A proven track record. $200K+ earned on Upwork, 345+ delivered projects,
and maintained across 622+ logged hours. Top Rated status and Google Certified Mobile Developer credentials. Clear communication. Daily updates, weekly demos, honest timelines. No
surprises, no missed deadlines, no vague status reports.
Full ownership. I don't just take orders. I'll push back on bad specs,
suggest better approaches, and treat your product like my own.
AI-ACCELERATED DEVELOPMENT
Most freelancers marketing "vibe coding" generate fragile AI-written code that breaks the moment real users arrive. I take the opposite approach: senior engineering decisions, AI-accelerated execution. The tools speed me up; the quality comes from eight years of real mobile engineering.
Cursor AI — AI-native IDE for multi-file refactors, test generation, and pair-programming on complex Flutter and React Native codebases.
Lovable — Rapid MVP prototyping for founders validating ideas, then graduated to production-grade Flutter or React Native builds with proper architecture.
Replit — Cloud-based iteration, live collaboration, and instant deploys for client demos and investor-ready prototypes.
Base44 — Full-stack app generation with built-in authentication, database, and hosting. Ideal for internal tools, admin dashboards, and SaaS MVPs.
Bolt.new, v0, Claude Code, Windsurf — additional tools in my stack for the right use case.
The outcome: idea to validated, shippable product in 3 to 4 weeks instead of 3 months, built on architecture that actually scales past v1.
TECH STACK
Mobile Flutter, React Native, Swift, SwiftUI, Kotlin, Java, Dart
AI tooling Cursor, Lovable, Replit, Base44, Bolt.new, v0, Claude Code

HOW WE WORK TOGETHER
Discovery — a free 30-minute call to scope your project properly and agree on whether I'm the right fit.
Planning — clear milestones, fixed timeline, agreed deliverables. No vague "we'll figure it out" contracts.
Build — daily progress updates, weekly demos so you see real work, not status reports.
Launch — App Store and Play Store submission, deployment, and handoff with full documentation.
Support — 30 days of free post-launch support on every project.
Whether you're a founder validating an MVP, a startup scaling to v2, or an established business modernizing a mobile product, I can help you ship faster and better.
