Rust & Tauri Performance Specialist | AI Mobile App Developer

Is your team looking for 𝗹𝗶𝗴𝗵𝘁𝗻𝗶𝗻𝗴-𝗳𝗮𝘀𝘁, 𝘀𝗲𝗰𝘂𝗿𝗲, 𝗮𝗻𝗱 𝗵𝗶𝗴𝗵𝗹𝘆 𝗰𝗼𝗻𝗰𝘂𝗿𝗿𝗲𝗻𝘁 applications that perform flawlessly across desktop and mobile? My expertise lies in leveraging Rust and Tauri to build groundbreaking 𝗰𝗿𝗼𝘀𝘀-𝗽𝗹𝗮𝘁𝗳𝗼𝗿𝗺 𝘀𝗼𝗹𝘂𝘁𝗶𝗼𝗻𝘀 that optimise for efficiency and reliability, solving critical performance and scalability challenges. With over 5 years of full-stack development experience, including 𝟮+ 𝘆𝗲𝗮𝗿𝘀 𝗱𝗲𝗱𝗶𝗰𝗮𝘁𝗲𝗱 𝘁𝗼 𝗵𝗶𝗴𝗵-𝗽𝗲𝗿𝗳𝗼𝗿𝗺𝗮𝗻𝗰𝗲, 𝗻𝗼𝗻-𝗯𝗹𝗼𝗰𝗸𝗶𝗻𝗴 𝗮𝘀𝘆𝗻𝗰 𝗥𝘂𝘀𝘁 𝘄𝗶𝘁𝗵 𝗧𝗼𝗸𝗶𝗼, I've consistently delivered robust solutions in demanding environments. I don't just write code; I transform complex problems into tangible business results. 𝗙𝗼𝗿 𝗲𝘅𝗮𝗺𝗽𝗹𝗲, I recently helped a client re-write their Bluetooth connection manager across multiple platforms, 𝙧𝙚𝙙𝙪𝙘𝙞𝙣𝙜 𝙡𝙖𝙩𝙚𝙣𝙘𝙮 by over 500ms per connection by expertly re-architecting their app in Tauri using Rust. This cross-platform solution now seamlessly handles multiple connections concurrently for Windows, Linux, macOS, and Android. My work on a 𝙎𝙤𝙡𝙖𝙣𝙖 𝙞𝙣𝙙𝙚𝙭𝙚𝙧 in Rust for another client ensured highly concurrent data processing from RPC endpoints to 𝙆𝙖𝙛𝙠𝙖, implementing robust CI/CD with GitHub Actions and Docker for enterprise-grade deployment. Beyond performance, I've also focused on expanding market reach by over 100% by re-building an iOS-only fitness app for Android. My contributions extend to decentralized systems, including the Holochain-based peer-to-peer API with Rust and 𝙒𝘼𝙎𝙈 𝙘𝙤𝙢𝙥𝙞𝙡𝙖𝙩𝙞𝙤𝙣, demonstrating versatility in cutting-edge technologies. My passion for innovation extends to crafting intuitive mobile-first applications and integrating cutting-edge 𝘼𝙄 and Large Language Model (𝙇𝙇𝙈) features to enhance user engagement and automate complex workflows. Whether it's adding an AI chat prompt to a core fitness app or designing sophisticated agentic workflows, I'm committed to building intelligent, impactful, and highly performant digital products.
