How I Build Tech for Good – 3 Core Principles

  1. Open, Inclusive & Interoperable – Keep the internet decentralized, accessible to everyone, and built on open standards and open‑source code.
  2. Human‑Centered Privacy & Agency – Design for individual empowerment, making privacy and security fundamental while giving users full control over their digital lives.
  3. Transparent, Community‑Driven Impact – Operate with open, community‑led processes that prioritize public benefit, equity, and global inclusion over pure profit.
