Flask: Build powerful and scalable web applications
Flask is a lightweight and flexible Python web framework ideal for building everything from simple web pages to complex web applications and APIs. Its minimalist approach allows developers to choose the tools and libraries they need, offering greater control and customisation. This makes Flask a popular choice for startups, small businesses, and individual developers who require bespoke solutions.
What to look for in a Flask freelancer
When hiring a Flask freelancer, look for demonstrable experience in:
- Building and deploying Flask applications
- Working with databases (e.g., PostgreSQL, MySQL, MongoDB)
- Understanding of RESTful APIs and API design principles
- Front-end technologies (e.g., HTML, CSS, JavaScript) for full-stack development
- Version control systems like Git
A strong portfolio showcasing previous Flask projects is essential. Look for clear code, well-documented projects, and evidence of problem-solving abilities.
Main expertise areas within Flask
