Language-learning app in Flutter (variable budget)
We are looking for a freelancer(s) to participate in the development of a hybrid application on Flutter (web + mobile version for Android/iOS)
with backend on Azure/Python, designed for learning foreign languages.
The application allows creating courses, lectures, and pages using an embedded editor. For students, it offers tools for determining language proficiency, taking notes, saving links, creating a dictionary, completing courses, and interacting with an AI assistant that can answer questions about grammar, vocabulary, suggest additional exercises, and more. All courses are based on advanced didactic methodology developed during teaching at the Goethe-Institut in Germany, which helps overcome the fear of speaking a foreign language.
Currently, a working PoC on Flutter with backend on Azure has been implemented.
We are looking for:
Flutter frontend developer
Backend developer on Azure/Python
Ideally, this will be the same person who will initially work with me on development but in the medium term will be able to take over further development, professionalize the codebase, and potentially become technical lead of the project as the team grows.
Budget and duration of the project will be discussed based on your estimates. The scope of work is large.
Candidate requirements:
High code quality:
Adherence to zero warning policy;
Practical experience applying clean code, SOLID principles, well-thought-out architectural approaches;
Testability, understanding the importance of maintainability in a multifunctional application;
Ability to create stable, well-structured code that is easy to scale.
Professional communication and teamwork:
Ability to clearly assess workload, meet deadlines;
Experience in team development, including proper use of Git/GitHub;
Willingness for open dialogue, code comments, task reviews, etc.
Experience in relevant projects (track record):
For Flutter developer: demonstrated results in mobile/web projects on Flutter (portfolio, GitHub, application links, etc.); preferably – examples of solving non-standard architectural or UX tasks, as well as design
For Azure/Python developer: practical experience building backends using Azure (Functions, Web Apps, Cosmos DB, etc.) and Python; experience with AI/ML integration (LLM, GPT, embedding search) is welcome but not mandatory.

Thank you for sharing the detailed vision for your hybrid language learning application. I’m highly interested in contributing to this project, both in the short term as a hands-on developer and potentially in the long term as a technical lead, helping scale and professionalize the codebase.
I'm full stack expertise with fluter and Azure, python, and I have Proven experience building hybrid apps using Flutter for web and mobile, and also Backend development using Azure Functions, Web Apps, Cosmos DB, and Python/FastAPI, Integration of AI/LLM assistants (GPT, embeddings) for intelligent support features, especially worked on educational platforms with interactive content editors, progress tracking, adaptive quizzes, and user dashboards
so Having reviewed your requirements carefully, I’ve also identified a couple of potential challenges:

Flutter: I have been coding in it for the last two years. I have two small programs I can show.
Azure: I haven't worked with it, but I have extensive experience with AWS. So probably functions are something like AWS Lambda, and Cosmos DB is like Mongo + DynamoDB.
Python: I have written a lot in Python (more than 10 years). Mainly backend.
