Building Reactive NetworkReactive Network is the first-of-its-kind event-driven, parallelized EVM, allowing developers to write interactive Smart Contracts (or Reactive Smart Contracts) by eliminating one of the fundamental limitations of EVM: the lack of reactivity. Reactive Network blockchain transactions are created according to subscriptions based on events (log records) of external ecosystems (EVM and non-EVM). Reactive Network allows for unmatched performance thanks to the virtual subnet system called ReactVMs, processing tens of thousands of transactions on a single CPU core.My responsibilities include:- Building the project from its pre-idea stage- Managing, supervising, and hiring for the Software Engineering, Quality Assurance, DevOps, Tech Writing, and DevRel teams- Conducting market research, making decisions about network's structure, tech stack, etc- Providing vision leadership- Making public appearances, giving talks and presentations, and participating in conferences, podcasts, and AMAs- Fundraising: preparing related materials and communicating with VCs- Building and maintaining node and validator infrastructure- Taking ownership of infrastructure- Handling a million other things
