Amit K.

Are you looking for a hands-on mobile product partner who can actually ship? I’m a mobile-focused product engineer with 11+ years of experience building, shipping, and scaling Android, iOS, Flutter, and Kotlin Multiplatform apps for startups and product teams worldwide. I don’t just write code—I help founders turn vague ideas into working products, fix failing MVPs, and take apps from zero → store launch → monetization. I’ve built consumer apps, AI-powered tools, privacy-first platforms, and large-scale production systems used globally. If you need someone who can own mobile execution end-to-end—architecture, UI, integrations, performance, and launch—you’re in the right place. What I Do * Build mobile-first MVPs using Flutter or Kotlin Multiplatform * Develop production-grade Android & iOS apps (Jetpack Compose, Swift interop where needed) * Architect shared business logic, offline-first data layers, and scalable app foundations * Integrate AI features directly into mobile apps (OpenAI, Gemini, Firebase ML, on-device ML) * Design monetization flows (subscriptions, IAPs, AdMob, RevenueCat) * Handle Firebase, push notifications, auth, analytics, and CI/CD * Step in to rescue stalled or poorly built apps and bring them to launch What Sets Me Apart ✅ 11+ years building real products—not demos ✅ Founder mindset: I optimize for speed, clarity, and business outcomes ✅ Deep mobile specialization (not a generalist pretending to be mobile) ✅ Proven experience with AI-powered mobile features in live apps ✅ Comfortable working solo or alongside founders, designers, and backend teams ✅ Clear communication, proactive updates, and zero hand-holding required I’ve worked with clients and teams across India, the US, Europe, Australia, and Singapore, and I’m used to async, remote-first collaboration. Selected Work (Real Apps, Live Users) Safe2Marry – Legal & risk-awareness mobile platform * Flutter-based cross-platform app with Firebase + AI integrations * AI-powered legal roadmaps, calculators, and content summarization * Built subscriptions, analytics, and community features from scratch Actionz (The Magic Word) – AI-powered life guidance app * Kotlin Multiplatform with shared UI & business logic * OpenAI-driven insights, notifications, and habit nudges * Designed for fast iteration and experimentation Josh.ai – Privacy-first smart home platform * Senior Android Engineer on a production AI/NLP system * Migrated legacy Java → Kotlin, rewrote core UI and architecture * High-performance real-time systems using WebSockets and Coroutines Scantrust – Anti-counterfeit & secure QR scanning * Kotlin-based Android app used by global brands * Camera, security, and performance-critical features * Reduced technical debt and enabled future ML capabilities (Details available on request or via portfolio links.) Tech Stack (Focused, Not Bloated) Mobile * Flutter, Kotlin Multiplatform (KMP) * Android SDK, Jetpack Compose * iOS integrations where required AI / Intelligence * OpenAI, Gemini * Firebase ML, TensorFlow Lite * On-device & cloud-assisted AI features Backend & Infra (Mobile-Centric) * Firebase (Auth, Firestore, Functions, Analytics) * REST APIs, WebSockets * CI/CD: Codemagic, Fastlane, GitHub Actions Monetization * RevenueCat, In-App Purchases * AdMob, subscription systems How Clients Typically Use Me * “Build my MVP fast, but properly” * “Fix this app and get it ready for launch” * “Add AI features to an existing mobile product” * “Own mobile while we focus on business” If that sounds like what you need, we’ll work well together. Final Note I’m selective about projects. I work best with founders and teams who value clean execution, honest timelines, and long-term thinking over quick hacks. If you’re building something meaningful and want a senior mobile engineer who can think like a product owner—let’s talk.
