    "Hussien was great to work with. He did this Android app for us at very short notice, worked over the weekend and sent all files for us to test and allow feedback. He's just the type of freelancer you hope to find and work with on Upwork. The code and deliverables were exactly as we requested and he accommodated small changes for us without any fuss. Highly recommended." Sam Kelly, LifeSize Touch Ltd -------------------------------------- Hello! I am a Mid-senior Android developer who is committed to ensuring client satisfaction. My formula is simple: ✔️clear requirements ➕ Reasonable time and budget ➕ Clean code 🟰 Happy Client. And when my clients are happy, I am happy too. I believe in providing value upfront, which is why I like to offer a small demo app at no cost to my clients before we begin working together. This ensures that we are on the same page and that you are satisfied with my work before any payment is made. For long-term projects, I prefer working with GitHub so that you can monitor the work done and download the code at any time. And before we start any contract, I will provide you with a ❗FREE demo app ❗ that meets your important requirement, as proof of my experience. Plus, I offer 2 weeks of FREE support for any bugs or minor changes. -------------------------------------- Don't just take my word for it - here's what some of my clients have said: "Great work really. Well-formatted and organized code along with a smoothly working app with a correctly implemented MVVM pattern, also you follow good practices and fully utilize Kotlin's powerful features and code recommendations, you did a great job here." - Feedback from an Udacity reviewer on the AsteroidRadar project. "Hussein did a really excellent job converting my Android app to run in the background, he was friendly and knowledgeable and completed the work quickly and with no fuss. He exceeded my expectations for the work and I am very pleased with the final result. I hope to employ him again on future work. I unreservedly recommend Hussein for Android work." - My first feedback on Upwork. -------------------------------------- In addition to my development skills, I am also experienced in Firebase products such as Firestore, Storage, Crashlytics, and Analytics. I can build a CI/CD pipeline for Android app publishing on the Play Store and automate screenshot generation using Fastlane. Whether using Compose or XML, I am dedicated to writing clean code, in a multimodule architecture, and following best practices. I am always eager to learn new frameworks and stay up-to-date with the latest Android components and patterns, such as TesnorfFlowLite, Jetpack Compose, and MVI Pattern. And while I am new to Upwork, I am confident in my abilities and offer a 100% Money-Back Guarantee if my service falls short of your expectations. If you're interested in working together, please feel free to contact me through Upwork messages. I look forward to hearing from you!
