I have a steady flow of Flutter work that ranges from polishing existing Android builds to launching brand-new cross-platform apps. Right now I need someone who can jump in immediately and deliver both: • Customisation on my current Flutter codebase: this covers user interface updates, new feature enhancements, and performance improvements. The apps already consume JSON through REST APIs and rely on SQLite for local storage, so you must be comfortable tweaking and extending those layers without breaking existing functionality. • Green-field development for upcoming releases: the roadmap includes billing solutions, data-driven utilities, and bespoke logic-heavy tools that must run smoothly on both Android and iOS. Clean architecture, solid state management, and pixel-perfect UI/UX are essential. Timelines are tight—ASAP delivery is expected—so please submit your final, realistic quote up front. I work primarily with Indian clients and prefer budget-conscious bids, but I won’t engage in post-bid renegotiations. If your profile shows proven Flutter, Dart, REST/JSON and SQLite expertise and you’re able to dive in right away, I’d love to review your offer and timeline.
