About
Who Is Vivek Yarra?
I'm a Founding Engineer with 15 years of deep systems experience, specializing in the architecture that most developers never see: native security layers, offline-first synchronization, and distributed systems that work when the network doesn't.
My career follows a simple arc: Start platforms from scratch (founding engineer of E70, serving 100K+ students), scale them to enterprise level (Samsung, TCS, Cambridge partnerships), and own the critical infrastructure (84% of security systems, primary architect of authentication).
84% security system ownership
I bring the rare combination of entrepreneurial drive and principal-level technical depth—someone who can architect the solution, write the critical code, and ship it to production. See the full project portfolio or explore the technical skills in depth.
