I’m planning a complex application that must feel native on desktop, mobile, and the web alike. The core architecture still needs to be designed, so I’m looking for someone who can help me shape everything from the back-end data layer through to sleek, responsive front-end interfaces. Because there’s no fixed deadline, we can iterate thoughtfully, choose the right tech stack together, and build clean, maintainable code rather than racing toward quick fixes. If you’ve shipped truly cross-platform products before, know your way around modern frameworks, and can explain trade-offs clearly, let’s discuss how you would tackle the project and outline realistic milestones.
