    Are you tired of low-quality code, over-billed hours, missed deadlines, and extremely buggy features? Want to work with an experienced engineer who is as passionate about your project as you are and can seamlessly translate your ideas into an app? Let’s chat! Who am I? My name is Dinko, an expert mobile & TV solutions engineer. My goal is to create the app you are dreaming about with the least amount of friction possible. I cannot help everyone, but you may be a right fit if you think: 🔸 ”I have a brilliant idea, but I don’t know where to start” 🔸 “My product is already established, I need someone with deep technical knowledge to take it to the next level” 🔸 “The app is full of bugs, I want them gone” 🔸 “This seems to be a job for an experienced software architect so I can scale later” 🔸 “I want someone who can communicate effectively, work alone and make this happen” Working with me will: ✅ Ease your mind when it comes to code quality ✅ UI will be pixel-perfect and seamless ✅ The app will have minimal bugs ✅ Communication will be clear and frequent ✅ Robustness and scalability will be achieved by using the best architecture approaches and an appropriate amount of automatic tests ✅ Speed of development will be at peak level by leveraging the latest mature technologies and tools I’m not everyone’s cup of tea, so here are some signs we might not be a great fit: ✖ You have a tight budget and are looking for a cheap developer ✖ You like to push people to work faster and then complain about the quality ✖ You like to have 100% control over every detail of the project I’ve previously been engaged with projects in the following domains: E-commerce, fitness apps, social media, and OTT. Services I provide: ➡️ Native app development for Android using Kotlin and iOS using Swift ➡️ Hybrid app development using Flutter and Dart ➡️ Backend development using Firebase Ready to know what it feels like to work with an engineer who truly cares about your success?
