Mualif Ulil M.

Full-Stack & Mobile MVP Builder | Next.js, Supabase & Flutter

Most founders spend months juggling separate backend engineers, web developers, and mobile teams—only to end up with a disconnected MVP, delayed timelines, and blown budgets. I solve that. I build production-ready digital products end-to-end: from scalable web architecture (Next.js) to cloud backends (Supabase) and native-feel mobile companion apps (Flutter/React Native). You work with one dedicated engineer who owns the entire product vision, not three separate handoffs. 🚀 What I Build & Ship: • Full-Stack B2B SaaS: Multi-tenant platforms, role-based auth, real-time dashboards, and Stripe billing built to scale from day one. • Mobile Applications: High-performance Flutter & React Native apps published to the App Store and Google Play. • Real-World Products Shipped: Point-of-Sale (POS) systems, warehouse inventory trackers, logistics/fleet management, and booking platforms. • Pragmatic AI Automation: Custom OpenAI/Claude API integrations that automate operational bottlenecks (real workflows, not just a bolted-on chatbot). 💬 Track Record: • 100% Job Success Score · 26 Completed Projects on Upwork • "Ulil is an excellent communicator and a great developer. I would happily work with him again in the future." — Founder, Music Platform 🛠 My Engineering Standard: - Architecture & scope mapped upfront—no surprise scope-creeps. - Milestone-based delivery with continuous Loom video walkthroughs. - Clean, thoroughly documented TypeScript/Dart codebase that your internal team can inherit seamlessly. 📩 Let's build your product Tell me what you're building. I'll reply within a few hours with honest feedback on scope, architecture, and timeline. Free 15-minute scoping call if it looks like a mutual fit.
