I build production-grade mobile applications and the backend systems behind them. If your product needs a Flutter application, custom APIs, cloud infrastructure, native functionality, in-app purchases, or subscriptions, I can own the system end to end. I’ve built and shipped production applications used by real users. One example is I See, a live Flutter application with AI-powered multimodal understanding across images, video, and audio, document processing, OCR, AI conversations, reading, summarization, and Read Aloud. I See combines: • Production Flutter development with native components • A custom Rust backend/API • AWS, Google Cloud, and Firebase infrastructure • Gemini, GPT, and other AI/LLM integrations • Document processing and OCR • S3/GCS-based file and document storage • In-app purchases, subscriptions, and Google Play Billing integration • User accounts, subscriptions, and credit/wallet management • Production deployment and ongoing releases through Google Play It’s one example of the kind of end-to-end product I build and take into production. I can build the backend too If your application needs a serious backend, I can design and build that layer as well: APIs and business logic, authentication and user data, databases, subscriptions and billing, file/document handling, credit or wallet systems, and the reliability mechanisms required to keep everything working correctly when things fail. I’m comfortable working across the application and backend rather than treating them as separate pieces of a project. That means I can make architectural decisions with the entire product in mind, from the mobile experience through the API and data layer to the cloud infrastructure supporting it. Projects I’m particularly well suited for I’m a strong fit when you need: • A production Flutter application • A custom backend/API rather than a Firebase-only architecture • Native functionality alongside Flutter • AI/LLM integration backed by real application infrastructure • Document, media, or file-processing pipelines • Subscription, billing, credit, or wallet systems • AWS and/or Google Cloud infrastructure • Google Play deployment and subscription integration My Engineering Background My background extends beyond application development, with experience in Rust, C/C++, native development, operating-system APIs, networking, media pipelines, WebRTC/GStreamer, graphics, and audio. I’ve also worked with technologies including OpenGL, OpenAL, Jolt Physics, Steam Audio, and AWS and Google Cloud SDKs. If you need someone who can build the mobile application, design the API behind it, integrate the cloud infrastructure, handle native requirements, and take the product through production deployment, that's the kind of work I do.
