Build & Ship by Yashesh Bharti
Developer infrastructure
Peer-to-peer deployment platform written in Go. Auto-detects 15+ frameworks, blue-green deploys, WireGuard mesh, AES-256 secrets, no cloud lock-in.
Better Authenticator by Yashesh Bharti
Authentication and 2FA
iOS keyboard that surfaces TOTP codes above the letters. One tap to paste into any login field.
Purelymail Calendar by Yashesh Bharti
Privacy-first calendar app
Calendar and meeting-invite handling for Purelymail mailboxes, designed to preserve the privacy posture users picked the mailbox for.
PulseProof by Yashesh Bharti
Proof-of-humanity infrastructure
On-device rPPG liveness in under two seconds. SDKs for iOS, Android, and Web. SOC 2 Type II, GDPR, HIPAA.
02Areas
What I do
- Production infrastructure: deployment systems, mesh networking, observability, CI/CD.
- Authentication and identity: TOTP, liveness, AI-agent authorisation, signed verification tokens.
- Privacy-first apps: on-device ML, local secrets, zero-data-leak architectures.
- AI systems: agents, on-device inference, vision and voice pipelines.
- Full-stack product engineering: Next.js, React, TypeScript, Go, Python, Swift, Kotlin.
