Although Flask is a great tool, you should typically have a variety of tools at your disposal to get placed. You may broaden your skill set by studying Django, Rails, or Tornado. You can focus on one area of your skill set by learning javascript for the front end or SQLAlchemy or Redis for the back end.
Top MNCs are ready to hire flask developers with excellent skill sets. When looking for a career, strive to find chances that strike a balance between what you want to do and what possible employers want you to do. Network with user groups or interact online with projects around you, and work to understand the opportunities that can help you in getting placed. Registering yourself with a freelancer job portal like Eiliana.com can help you in getting a job.
