Tonic.Foundation

Tonic.Foundation is an innovative project aimed at revolutionizing the way charitable organizations and donors interact and collaborate. It serves as a blockchain-based platform that leverages the power of decentralized finance and digital assets to promote transparency, efficiency, and inclusivity in the philanthropic sector.

At its core, Tonic.Foundation seeks to address some of the inherent challenges that traditional charitable organizations face, such as lack of transparency, high administrative costs, and limited access to funding. By harnessing blockchain technology, the platform ensures transparency by recording all transactions on a public ledger accessible to all participants, creating an immutable and auditable record of donations.

One of the key features of Tonic.Foundation is its integration of decentralized finance mechanisms. Through smart contracts and decentralized applications (DApps), donors can directly contribute digital assets, such as cryptocurrencies, to charitable causes. This eliminates the need for intermediaries, reduces transaction costs, and enables instant cross-border transfers, thereby increasing the efficiency of donations.

Later, I used advanced ES6 concepts to write concise code and collaborated with DevOps engineers to make a low-latency, high availability, and high-performance application. Finally, I designed the database with PostgreSQL, delivered architecture for new features using best practices, planned sprints, and participated in client meetings and discussions.
