I maintain a production Android app that combines React (React Native), Dart (Flutter), and native Kotlin components. I now need a few part-time developers who can plug into the existing code-base and keep momentum going week after week. The immediate priority is rolling out brand-new user-interface features. Alongside that, every session will involve hunting down bugs we uncover in QA and tightening up performance whenever profiling calls out slow paths or memory leaks. You should be comfortable switching between: • React Native JSX screens and hooks • Flutter widgets written in Dart • Native Android modules in Kotlin, Android Studio, and Gradle Git for version control, Jira for tickets, and regular pull-request reviews keep the workflow organised. I’ll assign concise tasks with clear acceptance criteria and expect incremental, well-documented commits so nothing gets lost. Typical deliverables per sprint • A new UI screen or component fully integrated and passing instrumentation tests • At least one verified bug fix with before/after notes • Profiling report or measurable performance gain when optimisation work is assigned If you can dedicate a consistent block of hours each week, communicate clearly, and move confidently across all three stacks, let’s talk and schedule a short paid trial task.

Hi there, I have read your project requirement and you need part-time developers who can work across a hybrid Android codebase (React Native + Flutter + Kotlin), focusing on UI feature development, bug fixing, and performance optimisation in an ongoing sprint-based workflow. We have experience working in mixed-stack environments and can handle React Native screens, Flutter widgets, and native Kotlin modules, along with Git workflows, Jira-based task management, and structured PR reviews. We can contribute consistently with clean, well-documented commits and measurable improvements. A few quick questions: ================== How many hours per week are you expecting per developer? Which part of the stack currently needs the most focus (React Native, Flutter, or Kotlin)? Do you already have CI/CD and testing pipelines in place? What is your preferred timezone overlap for collaboration? Best Regards, Srashtasoft Team

Hi, When I read your setup, it immediately felt like a real production environment where speed and consistency matter more than anything else. You’re not looking for isolated freelancers, you need developers who can comfortably live inside a mixed-stack codebase and keep things moving without breaking flow. I’ve worked in similar multi-layer mobile systems where React Native screens, Flutter modules, and native Kotlin components all sit together in one ecosystem. The key in such setups is not just writing features, but understanding how each layer interacts so UI updates, performance tuning, and native integrations don’t conflict with each other. My approach would be simple: pick up assigned Jira tickets, implement UI features in Flutter depending on the module, and handle native Kotlin work when required. Alongside that, I always focus on clean incremental commits, clear PR descriptions, and making sure each change is testable and production-safe before merge. For bug fixing and performance work, I rely on profiling tools and real device testing to identify bottlenecks like memory leaks, slow renders, or unnecessary re-renders, then fix them without impacting existing flows. If needed, I’m comfortable starting with a short paid trial task so you can evaluate code quality and workflow fit before scaling involvement. Let me know the first task and I can start immediately.
