I need an experienced full-stack developer to jump straight into Sharekna, the Flutter mobile app I manage, together with its web-based Frappe/Node.js admin dashboard. The codebase is live, but a batch of lingering bugs and performance bottlenecks is holding us back from the next release. Here’s what I would like you to tackle first: • Debug and stabilise the current Flutter build, closing the crashes we see on login, profile editing and in-app notifications. • Optimise API calls between the Dart client, Python micro-services and our Frappe backend so screens load in under two seconds on average 4G. • Smooth out UI inconsistencies (fonts, paddings, dark-mode glitches) and fix the navigation stack so users return to the correct screen after deep links. • Extend the admin dashboard with a couple of new reporting widgets and polish the existing moderation queue—most of the hooks are ready, but the views need work. Tech you’ll be touching every day: Flutter, Dart, Python, Node.js, Frappe, REST/JSON and a sprinkle of WebSockets. I’ll provide full Git access, staging credentials and a short test plan the moment we start. A clean commit history, concise pull-request notes and passing unit tests are the acceptance criteria for each milestone.
