I’m assembling a dedicated development team to build a cross-platform mobile application from the ground up. This project is mobile-first, so every decision—from architecture to UI polish—should reflect native-quality performance on both iOS and Android. Project focus The work spans full-stack mobile development. You will be responsible for planning, coding, testing, deployment and final hand-over; I don’t plan to split this into isolated tasks. Daily stand-ups, Git-flow, code reviews and an automated CI/CD pipeline are expected so we can iterate quickly and keep quality high. Core technologies The stack already outlined includes JavaScript/React (React Native on the client), Python/Django and Java/Spring for backend services, plus Dart/Flutter for rapid UI prototyping. Parts of an existing C++ library will need to be wrapped for mobile, so familiarity with native module bridging is important. Deliverables • A milestone-driven roadmap and sprint plan • Fully functional iOS and Android apps ready for App Store & Google Play submission • Scalable backend APIs deployed to AWS or GCP • Automated unit, integration and UI test suites integrated into CI/CD • Comprehensive documentation and a knowledge-transfer session at project close Acceptance criteria Clean, well-commented code; ≥90 % test coverage on critical modules; zero blocker defects at hand-off; successful builds in the pipeline and approval from both app stores. If your development team has shipped similar apps, include store links or public repos and outline each member’s role so I can see how you collaborate in practice.

I lead and assemble senior mobile teams that ship production-grade cross-platform apps with strong backend foundations and disciplined CI/CD. We’ve delivered React Native and Flutter apps backed by Django and Spring services on AWS, including native module bridging for C++ libraries. My role covers architecture oversight, sprint planning, code standards, and release governance, with senior engineers handling client, backend, and DevOps tracks. Approach: Phase 1: Architecture blueprint and sprint roadmap. Define domain boundaries, API contracts, auth model, and C++ bridging strategy. Phase 2: React Native production client, Flutter for rapid UI validation where needed, with native modules wrapping the C++ core via JNI/Obj-C++. Phase 3: Django or Spring microservices with scalable REST APIs, containerized and deployed to AWS or GCP. CI/CD: Git-flow, PR reviews, automated unit, integration, and UI tests integrated into pipeline. Target ≥90% coverage on critical paths. Final phase: Store submission, performance validation, documentation, and structured knowledge transfer. We operate milestone-driven with clear ownership across mobile, backend, and infrastructure to ensure predictable delivery and zero blocker defects at hand-off. Timeline: 4–6 months

Hey — saw your post about assembling a mobile app dev team for a cross-platform build from the ground up. Biggest risk with these projects is misaligned tech choices early on, which can make future scaling and maintenance painful. Quick question before I suggest an approach: Do you already have a defined tech stack in mind (e.g. Flutter/React Native), or are you open to recommendations based on your feature roadmap? I’ve helped set up and lead teams for greenfield mobile builds before, including choosing the stack, structuring the sprints, and defining a clean architecture that doesn’t slow you down later. If you share your brief, feature list, or any early wireframes, I can review and tell you what kind of team setup and timeline actually makes sense.

Hey — saw your post about assembling a team to build a cross-platform mobile app from the ground up. The biggest risk at this stage is unclear architecture and roles, which can easily slow the whole project or blow the budget later. Quick question before I suggest an approach: Do you already have a product spec/roadmap, or are you expecting the team to help define features and technical scope as well? I’ve led and worked within cross-platform app teams before (React Native and Flutter), setting up clean architecture, CI, and collaboration flows so dev, design, and QA don’t step on each other. If you share your current spec, draft requirements, or even a brief, I can review it and give you a realistic view of what kind of team setup you actually need.

Hey — saw your post about assembling a team for a cross-platform mobile app from the ground up. The biggest risk in builds like this is misalignment early on — architecture, stack, and scope all drifting, which slows everything down later. Quick question before suggesting an approach: Do you already have a clear product spec or wireframes, or are you expecting the team to help shape the MVP as well? I’ve led cross-platform app builds end-to-end (React Native and Flutter), including setting up the architecture, CI/CD, and aligning dev, design, and QA so things don’t fall apart mid-project. If you can share your current spec, brief, or even a rough document, I’ll take a look and give you a realistic take on team structure, timeline, and tech.

This sounds like a serious build that needs a lead who actually understands how to bridge the gap between high-level JS and low-level C++. I’m not just a dev who pushes code; I’m a builder who focuses on the "why" behind the architecture. I’ve spent my time lately working on HaqGPT, which required that same mix of complex backend logic and a clean, responsive interface. I’m fluent in the stack you’ve outlined. Whether it's managing the React Native flow, handling the Python/Django backend, or wrapping that C++ library into a native module so it actually performs on mobile, I can get it done. I’m big on the "human" side of dev too—meaning I’ll be there for the daily stand-ups and I actually follow Git-flow and CI/CD protocols because I hate messy hand-overs as much as you do.
