Ahmad Bilal K.

I build cross-platform iOS and Android apps and, as a full stack developer, the web app, SaaS platform and admin dashboard behind them. Then I stay on to maintain them. Facebloom hit Top 20 on the Apple App Store. BUFF passed 50,000 users in year one. I'm the senior Flutter developer and mobile app developer who built both. 🏆 Top Rated Plus | 100% Job Success | $700K+ earned | 130+ completed jobs ✅ WHAT I BUILD Cross-platform mobile apps in Flutter. MVPs and full products from one codebase, shipped to the App Store and Google Play. The admin dashboard and backend. Firebase, Node.js, the MERN stack (MongoDB, Express, React, Node), PostgreSQL, REST APIs, Stripe payments and subscriptions, push notifications, in-app chat. Web apps, AI Agents and SaaS platforms. Full stack SaaS builds, custom dashboards, and system integrations that connect your app to the tools your business already runs. Existing apps. Finishing a half-built Flutter project, taking over from a previous developer, a FlutterFlow prototype OS and store updates, review rejections, and long-term app maintenance. AI inside the app, where it earns its place. Facial analysis and face matching from the phone camera, LLM-powered chat and assistants, on-device and cloud ML. ✅ PROOF Facebloom: I built the app and its FaceMatch feature. Top 20 on the App Store. BUFF: I built the fitness app and website. MRR grew 433% and churn dropped 40%, and I've maintained it on a retainer for over 18 months. Hudson, co-owner of BUFF, recorded a video review. It's in my portfolio. An on-demand HVAC platform (Flutter + PERN): mobile app, web app, AI Agents, CRM and SaaS. The same client has hired me four times over four years. Prickly Bear: a Learn to Earn app that raised $2M+ in funding. Most of my Upwork revenue comes from clients who hired me again. 🌟🌟🌟🌟🌟 "Ahmad exhibited a positive attitude and willingness to go above and beyond to meet our needs." ✅ HOW I WORK 1. I scope the product before the code: what ships in v1, what waits. 2. I'm honest about where AI earns its place and where it's just expensive. 3. I build for real devices and real load, not for a demo. 4. I stay after launch: store updates, OS changes, and the unglamorous fixes.
