Flutter + Supabase Developer (Contract) — Finish & Launch

Company Description

FLOWBRIDGE SOLUTIONS LLP is a software development company focused on building scalable, real-world products for both in-house initiatives and select external partners. The team emphasizes end-to-end product thinking, ownership, and long-term impact rather than traditional outsourcing models. Current work includes multiple internal projects, alongside collaborations on ideas the team believes have strong potential.

This environment offers opportunities to work on meaningful, product-focused solutions with room for technical and professional growth.

Role Description

We're looking for a hands-on Flutter developer to take a partially built early-learning app across the finish line and onto the App Store.

The app helps young students practice reading skills through interactive quizzes with text-to-speech and voice-based answers. The foundation is solid — Flutter frontend (Riverpod), Supabase backend with the schema and most APIs already written as PostgreSQL functions — and you'll own the remaining ~25%.

What you'll do:

  • Set up and configure the Supabase backend (schema, functions, storage, auth are already written — you'll deploy and wire them up)
  • Build an adaptive question engine: select the next question based on student performance and resurface incorrectly answered questions (rules-based / spaced repetition — no ML required)
  • Implement voice-answer recording and grading (speech-to-text)
  • Import existing question content, polish remaining screens, and handle App Store submission via TestFlight
Must-haves:
  • Strong Flutter experience with at least one app shipped to the Apple App Store
  • Solid PostgreSQL skills — business logic here lives in plpgsql functions, so comfort writing and debugging SQL is essential (Supabase experience is a big plus)
  • Ability to work independently from an existing codebase and communicate progress clearly
