Need a mobile app, website, AI automation or vibe-coded project built, repaired or prepared for launch?
I help startups, founders and businesses turn ideas, unfinished codebases and AI-generated prototypes into secure, reliable and production-ready digital products.
I work across mobile app development, full-stack website development, AI automation, API integration and vibe-coded project recovery.
You can hire me to:
MOBILE APPLICATION DEVELOPMENT
• Build Flutter and React Native apps for iOS and Android
• Develop native Android and iOS features using Kotlin and Swift
• Integrate authentication, payments, notifications, maps and APIs
• Fix crashes, build errors, rejected store submissions and broken features
• Prepare and publish apps on Google Play and the Apple App Store
WEBSITE AND WEB-APP DEVELOPMENT
• Build responsive websites, SaaS platforms and business web applications
• Develop frontend interfaces using React, Next.js, TypeScript and JavaScript
• Build backend systems using Node.js, PHP and Laravel
• Create admin dashboards, customer portals and management systems
• Integrate PostgreSQL, MySQL, MongoDB, Firebase and Supabase
• Improve website performance, responsiveness, security and SEO
VIBE CODING AND PROJECT RESCUE
• Build applications rapidly using Replit and AI-assisted coding workflows
• Repair projects created with Replit, Cursor, Lovable and other AI coding tools
• Fix dependency conflicts, broken APIs, authentication errors and deployment failures
• Refactor unstable AI-generated code into maintainable production code
• Connect unfinished frontends to functional backends and databases
• Configure GitHub, environment variables, domains and production deployments
AI AUTOMATION
• Build AI-powered workflows and business automations
• Integrate OpenAI and other AI APIs into websites and mobile apps
• Develop chatbots, virtual assistants and intelligent support systems
• Automate lead capture, customer service, reporting and repetitive operations
• Connect CRMs, forms, databases, email platforms and third-party services
• Build custom API integrations and webhook-based workflows
My technology stack includes Flutter, Dart, React Native, React, Next.js, TypeScript, JavaScript, Node.js, PHP, Laravel, Kotlin, Swift, Firebase, Supabase, PostgreSQL, MySQL, MongoDB, REST APIs, Git and GitHub.
I work with VS Code, Replit, Cursor and modern AI-assisted development tools. Vibe coding helps accelerate development, while my software engineering experience ensures the final product is tested, secure, maintainable and ready for real users.
If your previous developer or AI coding tool left you with unfinished features, confusing errors or a failed deployment, I can inspect the codebase, find the root cause and provide a practical recovery plan.
What you can expect:
• Clear and consistent communication
• Well-structured, maintainable code
• Regular progress demonstrations
• Testing and quality assurance
• Honest estimates and documented handover
• Deployment and post-launch support
Send me an Upwork message with your requirements, existing codebase and current blocker. I will review the scope and recommend the best path to a working release.

Hi, I’m a Kotlin + Jetpack Compose Android developer who builds fast, reliable, modern Android apps and fixes broken ones.
Most Android apps suffer from slow dev cycles, outdated code, poor architecture, or inconsistent UI. That’s where I come in.
I specialize in:
• Adding new features to existing Android apps
• Modernizing legacy XML apps into Jetpack Compose
• Fixing crashes, ANRs, and performance issues
• Polishing UI/UX with smooth, responsive Compose layouts
• Integrating Firebase (Auth, Firestore, Messaging, Storage)
• Building real-time chat, media sharing, and notifications
• Implementing Bluetooth + hardware features
• Creating offline-first apps with smart caching
Why clients hire me:
• I write clean, scalable, maintainable code (MVVM + Clean Architecture)
• I move fast without breaking things
• I understand real-world constraints: deadlines, productivity, cost
• I communicate clearly and provide solutions, not excuses
I'm Perfect for:
• Fixing bugs your previous developer couldn’t solve
• Adding that one tricky feature you need ASAP
• Scaling or upgrading an existing Android app
• Starting a complete custom Android app from scratch
If you need a dedicated Android specialist who understands the platform deeply and delivers results, let’s talk.
Send your project details and I’ll tell you exactly how I can help.

I build complete digital products — not just apps. Using FlutterFlow and Flutter, I ship production-ready mobile apps fast, and I pair them with the marketing site or web/SaaS dashboard your business needs, built in Lovable. One developer, one connected system, instead of stitching together separate freelancers for app and web.
⭐ Top Rated | 92% Job Success | MVPs shipped in as little as 10 days
Recent work: a construction materials marketplace app, an AI-powered skin lesion detection tool, and a makeup organizer app — each shipped with the supporting web presence to match.
What I bring:
- FlutterFlow & Flutter development (Android since 2019, iOS since 2021)
- Web apps, SaaS dashboards & marketing sites via Lovable
- UI/UX design in Figma when a project needs it
- Firebase, API integrations, and backend connections
- Clean architecture and code I can hand off or maintain long-term
I sign NDAs, give regular progress updates on active work, and I'm equally set up for a fixed-scope MVP or a longer partnership. Tell me what you're building — happy to hop on a call and scope it out.
