Senior Front-End Developer
About Openmesh and Xnode
In today's world, a few large corporations control the majority of data and IT infrastructure, which leads to trust issues and negative consequences for society. Openmesh is a pioneering open-source cloud infrastructure and global open data network that aims to store important global data without intermediaries. It is the largest open web3 data lake, encompassing 80% of the crypto and web3 ecosystem. Openmesh plans to expand its data coverage to include public health and scientific research data in the near future.
Openmesh allows individuals to create their own decentralized data clouds, connect globally, share data securely, reduce deployment costs, and automate data cloud setup. It enables universal data access, eliminating interference from regulators, governments, corporations, and even its own creators. The possibilities are endless.
Core Products
Xnode, our flagship product, revolutionizes the way developers build decentralized data clouds. With Xnode, developers can create their own data clouds with data connectivity, APIs, and query and analytics engines in minutes instead of weeks or months, while avoiding licensing and setup fees. Xnode significantly reduces the costs and time involved in running and operating data clouds.
Pythia is a powerful analytics and query engine that transforms raw data into actionable insights. It empowers anyone to design, build, visualize, and deploy robust data products.
Unified APIs offer a single endpoint for all crypto and web3 data, ensuring accessibility without cost, licenses, registrations, or setup fees.
Our Vision
Our mission is to democratize data and address information asymmetry on a global scale. Quality and reliable data are essential for the internet to function effectively. We believe that access to accurate and unedited information is a fundamental right in a free and democratic society. Openmesh operates on core principles that retain data integrity and prevent centralized authority from altering data distribution or control. The infrastructure and technology stack are open-source and governed by a community of contributors.
