I'm the founder and sole developer of mibi, a B2B SaaS recruiting platform built from scratch. 114 REST endpoints, 8 AI agents (Anthropic Claude) for async interviews, CV scoring, and recruiter chat, multi-tenant PostgreSQL with per-client schema isolation, Stripe billing, LGPD compliance, and CI/CD with Sentry + PostHog observability. Stack: TypeScript, React 19, Next.js, Node.js, PostgreSQL, Vercel, Jest, Playwright. Building it solo meant making every architectural call myself: schema design, agent orchestration, billing flows, compliance. And living with the consequences in production. My day job is FoccoLOJAS, an ERP for furniture retail on GeneXus, Oracle and C#/.NET. Large legacy codebase, strict domain rules, enterprise integrations. Different from a greenfield SaaS, and I work well in both. I take on projects where the scope isn't fully defined and someone needs to own the outcome, not just close tickets.

Flutter developer with 2.5+ years of production experience shipping cross-platform apps for iOS and Android. My work is live on the App Store and Google Play — including Pocket, an AI voice expense tracker I co-founded that now has 20,000+ users across Arabic and English, and Lockers, a B2C logistics platform serving users across Saudi Arabia. What I build: ✔ Cross-platform apps from a single Flutter/Dart codebase (iOS + Android) ✔ Clean architecture with BLoC/Cubit, Dio/Retrofit, GetIt ✔ Firebase (Auth, Firestore, Remote Config, FCM, Analytics) ✔ In-App Purchases & subscriptions — dual-platform, tested in production ✔ Native Swift bridging via MethodChannel (AVAudioEngine, SFSpeechRecognizer) ✔ LLM integration (OpenRouter, Gemini) for AI-powered features ✔ Payments (Stripe, UrPay), Google Maps, real-time chat, PDF generation, push notifications Why it matters: I've shipped apps that are actually in users' hands — not demos, not prototypes. That means I've dealt with the unglamorous parts: App Store review rejections, IAP receipt validation edge cases, iOS permission prompts, ANR crashes on low-end Androids, localization bugs that only show up in Arabic. If your Flutter app needs to reach real users and survive them, I've done this before. My first Upwork client said: "He's a great communicator who kept me updated without even being asked and flagged decisions early." How to work with me: Send me your project brief or current codebase. I'll reply within a few hours with honest feedback on scope, timeline, and whether I'm the right fit. Available for fixes, features, or full builds — short-term or ongoing.
