I am excited about the opportunity to work on your minimal Android Position Size Calculator app. With solid experience in Kotlin and Jetpack Compose, I specialize in building clean, performant, and user-friendly Android applications following MVVM architecture. I will ensure your app is fully offline, privacy-first, and visually minimal while delivering smooth, responsive interactions. Using Room for calculation history and DataStore for settings, I will create a scalable and maintainable codebase that can easily expand into future versions, including a full trading journal, without sacrificing performance or UX quality. The result will be a utility tool that traders can rely on for quick and accurate calculations, with automatic updates and a polished, balanced interface. My approach prioritizes clean architecture, asynchronous operations to maintain responsiveness, and adherence to Material 3 design principles. I will implement a clean separation of concerns, smooth numeric input experience, and proper UI spacing to meet your 8dp grid standard. The app will support system, light, and dark themes, and calculation history will allow traders to quickly reference past inputs. I understand the importance of performance and minimalism for this utility, and I am committed to delivering a professional, fully functional Android Studio project that is ready to run.

Your position size calculator needs real-time calculations and smooth UX - I'll build this with Kotlin + Jetpack Compose using MVVM architecture. The auto-updating results while typing and clean Material 3 interface will make this fast for traders to use. I built a similar financial tool - an algorithmic trading bot with real-time PnL calculations and risk management that processes trades automatically. Also created a price aggregation engine tracking 800+ products with instant comparisons. You can see my work at ffulb.com. Available immediately and can deliver the complete Android app within 2 weeks. The codebase will be clean and extensible for your future trading journal features.

Hi, This is a great fit for my experience. I can build your minimal Position Size Calculator using Kotlin + Jetpack Compose with MVVM, ensuring a clean architecture and smooth UX. The calculator will update results instantly while typing, with a minimal Material 3 UI, emphasized quantity result card, and proper 8dp spacing. Calculation history will be stored locally using Room (last 10 entries) and DataStore will manage settings and theme modes (System / Dark / Light). The app will be fully offline, privacy-first, and optimized for fast performance. I can deliver a clean, extensible codebase ready for future features like the trading journal in Version 2. Happy to share Compose apps I've built and discuss the implementation. Thanks

Hello, I’d be glad to help build your **Minimal Position Size Calculator Android app**. I have **3+ years of experience in Native Android development with Kotlin** and strong experience building **clean, responsive apps using Jetpack Compose and modern Android architecture**. For this project, I would structure the app using **MVVM architecture** with a clear separation of UI, ViewModel, and data layers. **Jetpack Compose with Material 3** will be used to create a minimal, smooth, and responsive interface following proper **8dp spacing and system inset handling**. The calculator logic will update results **in real time while typing**, ensuring a fast and seamless user experience. For data management, I will use **Room database** to store the last 10 calculations and **DataStore** for theme and settings preferences. All operations will be **asynchronous using Kotlin Coroutines** to keep the UI fast and responsive. The code will be **clean, well-structured, and easy to extend**, making it ready for future features like a trading journal or analytics. I can also share examples of **Jetpack Compose apps I’ve built** and provide full documentation for running and maintaining the project. Best regards, Vinod Android / Flutter Developer

Hi, I can build this minimal Position Size Calculator using Kotlin + Jetpack Compose with clean MVVM architecture. The UI will be clean, responsive, and optimized for fast calculations. I will implement real-time calculation updates, Room database for the last 10 calculations, and DataStore for settings. The app will follow Material 3 design and run smoothly on Android Studio. I can deliver a clean, well-structured project that is easy to extend for future versions like the trading journal. I’m ready to start immediately and can complete this within a few days. Looking forward to working with you.

Hello, I’m a Kotlin Android developer experienced in building clean, fast, and reliable apps using Jetpack Compose, Material 3, and MVVM architecture. Your project aligns perfectly with my development approach—focusing on minimal design, smooth performance, and well-structured code rather than unnecessary complexity. I can implement the Position Size Calculator with real-time calculations that update instantly while the user types, ensuring a smooth and responsive experience. The app will be built fully offline and privacy-focused, exactly as required. For the architecture, I would structure the project using MVVM with a clear separation between UI, logic, and data layers to keep the codebase scalable for future versions. Room will handle calculation history (last 10 entries), while DataStore will manage theme and settings. The UI will be built using Jetpack Compose with Material 3, maintaining a clean layout, proper 8dp spacing, and full support for system navigation insets. I prioritize readable, maintainable code and polished UI/UX, ensuring the application feels fast and professional. I’m confident I can deliver a solid Version 1 that also prepares the foundation for your future trading journal features. I’d be happy to share my previous Compose-based Android work and discuss the implementation approach. Looking forward to collaborating. Best regards.

my Java Full Stack course, I gained hands-on experience with Java, Spring MVC, Hibernate, JDBC, JUnit, JSP, and RDBMS, which strengthened my technical and problem-solving skills. Additionally, I completed a 3-month Java Full Stack Internship at HDSOFT System, where I worked on Spring MVC–based applications, implemented CRUD operations, and supported frontend–backend integration. This experience provided me with practical exposure to real-world software development. I am particularly interested in a Java Developer role. Since is nearer to my location, commuting is convenient for me. Salary is not a concern at this stage; I am eager to gain experience, learn continuously, and make a valuable contribution to your organizat
