About Ali

Looking for a developer who not only writes code but understands your entire software architecture? As a graduate of Technical Computer Science (B.Sc.) and an experienced engineer, I combine deep theoretical knowledge with practical fullstack experience in app and web development.

What I can do for you:

Mobile App Development (Flutter & Firebase): I develop cross-platform apps for iOS & Android. My current project includes complex features such as real-time chats, Google Maps integrations, push notifications, and in-app purchases.

Custom Web & Reporting Solutions: I have experience in developing tailor-made database systems including web interfaces that translate data into dynamic HTML reports – ideal for companies that want to visualize and utilize their data.

E-commerce & Web Technologies: With a solid understanding of HTML/CSS/JS and Shopify, I support you in technically optimizing sales platforms or adding individual functions.

My Core Expertise:

Frontend: Flutter (Dart), HTML5, CSS3, Modern JavaScript.

Backend & Databases: Firebase (Firestore, Auth, Storage, Cloud Messaging), NoSQL data modeling, SQL/Custom DB solutions.

Cloud & APIs: Google Maps SDK, REST APIs, Cloud Functions.

Business Logic: Development of monetization strategies (in-app purchases) and optimized data models (denormalization) for maximum performance.

Why me? With my background in technical computer science, I value clean, maintainable code and a security architecture that meets current standards (e.g., Firebase Rules, Google Play guidelines). I accompany projects from the initial design through "Closed Testing" to productive release.

Let's discuss your project! Send me a message for a non-binding initial assessment.
