Strange.. me too. 😉 Love high-scale tech? Hell yeah!! me too. We got quite some similarities. We should really connect!!🤳 Hi, As a Senior Full Stack Engineer and AI Architect with a deep focus on mobile ecosystems, I don't just build apps—I architect resilient, high-concurrency systems. I specialize in taking products from "Figma-stage" to "Market-Leader," having led the technical vision for platforms that manage 1M+ transactions and serve over 100k+ active users. I have a proven track record in the Fintech and Privacy sectors, most notably as the Lead Architect for Zarpay, where I transitioned the infrastructure from a monolithic bottleneck to a scalable Microservices architecture. My expertise extends into complex mobile integrations, including engineering production-ready VPN tunneling logic (handling DNS leaks and battery optimization) and building AI-driven coaching engines that deliver real-time inference at the edge. With my background as a CTO, I am committed to streamlining the development lifecycle. By utilizing AI-orchestrated workflows and modular native bridges, I’ve consistently cut development time in half for my clients, allowing startups to launch production-grade MVPs in weeks rather than months. Technical Skills: 🐱‍🏍👇 - Mobile Development: Flutter (Senior), Dart, Native Bridges (iOS/Swift & Android/Kotlin), Xcode Optimization, Custom Haptics. - Backend & Infrastructure: Node.js, .NET Core, Microservices, RESTful APIs, JSON/XML, Monolith-to-Microservice Migration. - AI & ML: OpenAI Integration, TensorFlow Lite (Custom Model Training), Google ML Kit, AI-driven Data Analysis. - Security & Privacy: VPN Tunneling, Adblocking Engines, Secure Environment Management (Secret Vaults), Firestore Security Rules. - Databases: Firebase/Firestore (Relational Hub Models), PostgreSQL, MySQL, SQLite/Realm (Offline-First). Fun facts about me!! 🤷‍♀️ I’ve been deep in the crypto trenches since the early days, managing everything from my own nodes to a diverse portfolio of assets like ETH and NEAR. I treat your app’s uptime like a blockchain: it needs to be immutable, secure, and 100% reliable. ;) Hobbies: 🙌 - Startups & Technical Strategy - E-Sports - Football - Gaming - Crypto
