I've been working as a web developer for the past few years. Initially as a frontend developer and more recently as a full-stack developer. And I've held full-time jobs before and I quit my job to independently work on my startup projects. More recently I have decided that I don't want to rely on my startups succeeding to be able to be financially independent. So I want to get started as a freelance web developer so that I can work on short-term projects full-time or long-term projects part-time so that I have time to invest into my startups and take all the risks I can with them.

How do I get started, what are some tips from those who have done this before? Specific tips on hourly rate, how to get clients, how to present proposals etc. from people who have had success with this would be very helpful.

Just for reference, these are my specialities:-

1. UX design and complete product conceptualization/visualization with interactive UX prototypes using Figma
2. Angular or React for frontend, with state management (where needed) using best practices
3. REST or GraphQL backend using Python-based frameworks (Django, Flask or FastAPI). All Dockerized.
4. End-to-end automated testing using Cypress.
5. Maintain CI/CD pipelines
6. Porting web apps to native mobile apps via NativeScript. This lets me build web apps, and mobile apps all at once. Offering end-to-end solution on all platforms.
