I’m extending our engineering team on a long-term software development project that targets both iOS and Android. The job is hands-on coding: committing well-structured, tested features to our Git repo, reviewing pull requests, and gradually tackling more complex tickets as you grow with us. I’m specifically seeking a beginner to mid-level developer who (1) currently resides in the United States and (2) identifies as female. I want to invest time in mentoring someone reliable, curious, and ready to stick with the project for the long haul. The current stack is Swift and Kotlin with a RESTful back end. Familiarity with React Native, Flutter, or similar cross-platform tools is welcome but not mandatory—what matters most is clean code, steady communication, and a learning mindset. Deliverables • Source code merged to our GitHub repository for each assigned feature • Test builds running successfully on both iOS and Android devices or emulators • A brief written update at the close of every weekly sprint Acceptance Criteria • Features match user-story requirements and pass QA on both platforms • No new critical linter or static-analysis issues introduced • Unit tests and CI/CD pipelines complete without failure before merge We coordinate in Slack during Eastern-time working hours, but I’m flexible on the exact schedule as long as progress remains steady. If this sounds like the right fit, tell me about your current level, tool comfort, and earliest start date—let’s build something great together.

HELLO!! I have carefully reviewed your requirements for a US-based female junior software developer role working on iOS (Swift) and Android (Kotlin) development within a long-term, mentored engineering team. However, I want to be transparent that I do not meet the specific geographic and demographic requirements mentioned in your posting (US-based and female junior profile). If you are open to it, I can still support your project by contributing as a senior full-stack/mobile developer or by helping you onboard and mentor junior developers, set up clean architecture, CI/CD pipelines, code review processes, and scalable mobile app structure for Swift/Kotlin or cross-platform stacks. I have more than 10+ years of experience in mobile and backend development, including REST APIs, iOS/Android development workflows, Git-based team collaboration, and production-grade app delivery with testing and CI/CD integration. I WILL PROVIDE 2 YEAR FREE ONGING SUPPORT AND COMPLETE SOURC CODE, WE WILL WORK WITH AGILE METHODOLOGY AND WILL GIVE YOU ASSISTANCE FROM ARCHITECTURE TO PRODUCTION DEPLOYMENT AND TEAM WORKFLOW SETUP. If you would like, I can also help you structure a junior developer onboarding plan and sprint workflow to ensure smooth long-term scaling of your engineering team. I eagerly await your positive response. Thanks.

Hi there, I’ve read your project and I’m confident I can extend your engineering team with a reliable, curious developer who writes clean Swift/Kotlin and commits well-structured, tested features to your Git repo. I have hands-on experience shipping mobile apps on iOS and Android, working with REST backends, and I’m comfortable with cross‑platform tools like React Native or Flutter if needed. I’ll contribute by delivering features that pass QA on both platforms, reviewing PRs, and gradually tackling more complex tickets as I grow with the project. I’ll maintain steady, clear communication in Slack during ET hours, and I’ll provide a brief written update at the close of every weekly sprint. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. What is your preferred test strategy (unit tests, UI tests, and CI/CD integration) for new features, and do you already have any tooling or pipelines in place I should align with? Also, are there any must-have cross-platform considerations or dependencies I should be aware of before the first sprint? Best regards, Asad

Hi I can contribute to your mobile app as a reliable developer working with Swift, Kotlin, REST APIs, and Git-based workflows while steadily improving feature quality and code structure. The main technical challenge in a growing codebase like this is maintaining clean, testable code and stable builds across both iOS and Android while new features are continuously added. My approach is to follow strong coding standards, write modular and maintainable logic, and ensure every feature is properly tested and reviewed before merging. I have experience working with mobile development fundamentals, API integrations, version control, and CI/CD practices that keep builds stable and predictable. I’m comfortable collaborating in team environments, reviewing pull requests, and communicating clearly through sprint updates while gradually taking on more complex tasks. I focus on consistency, learning quickly within an existing codebase, and contributing in a way that supports long-term scalability. I’m also familiar with cross-platform concepts which helps when aligning logic across iOS and Android implementations. Thanks, Hercules
