Pros
Gained valuable experience in React Native, adding new skills to my resume. Opportunity to meet and learn from talented people. Growth potential: you'll have the chance to interview developers and take on tasks outside your scope. Immediate responsibility due to the lack of senior developers, which can be a pro if you're looking to grow quickly.
Cons
Equity is tied to deliverables, so your shares may be reduced for non-core tasks like research. Communication can be inconsistent, leading to confusion. No senior developer support; there was one initially, but they left or were let go. You may feel pressured to work full-time, though it's not required—ensure you log your hours carefully. Promised shares might not be granted. The company is not yet funded.
