Job Title: Expert FlutterFlow and Firebase Developer – Educational App (Stage 1) Project Description: Hello! I am a mother and I want to develop a high-quality, pedagogical spelling app called "SCXXX". My goal is to first create this app for my own children and their friends to help them master German spelling in a stress-free, effective way. If the app proves successful in this private environment, I plan to commercialize it in later stages. I am looking for a developer who is not only technically skilled but also shares an interest in educational tools. Technical Requirements: FlutterFlow and AI Efficiency: I expect you to be a power user of FlutterFlow. You should explicitly use the FlutterFlow AI features (AI Page Gen, AI Schema Gen, etc.) to achieve rapid results and efficient prototyping. Firebase Backend: You must be an expert in Firebase. The app's "brain" is a database of German vocabulary. You need to handle complex queries (e.g., cumulative filtering of words across different school grades). Modular Development: We will work in 6 Stages. This job post is specifically for Stage 1. If we work well together, I am looking for a long-term partner for the subsequent stages. Stage 1 Scope (The Core Dictation Engine): Level Selection: A two-step menu (School type and Grade). Important: Higher grades must automatically include vocabulary from lower grades (cumulative logic). Smart Audio Flow: Implementation of a precise Text-to-Speech flow: Target Word - 500ms Pause - Example Sentence - 500ms Pause - Repeat Word. Progress Tracking: Words must be tracked in Firebase (is_practiced = true/false) based on the child's input. Child-Friendly UI: Even in Stage 1, the design must be warm, inviting, and highly accessible for children (large buttons, large fonts). Your Profile: Profound experience with FlutterFlow and Firebase. Experience in integrating TTS (Text-to-Speech) and media timing. A keen eye for clean, child-friendly UX/UI. Reliable communication and a structured way of working. Full Specifications: A detailed requirement document (SRS) is prepared and will be shared with shortlisted candidates after an initial screening.
