Sri Pranav Tene

Founder & engineer · Lupyd · Hyderabad, India

I build private, real-time software from the wire protocol up.

Rust backends, end-to-end encryption with MLS and libsignal, WebRTC and QUIC transports, and the React, Tauri and Flutter apps on top, with C/C++, WebAssembly, Godot games and Shine - Photonic Circuit Simulator along the way. I built Lupyd, an end-to-end encrypted collaboration platform.

01 Selected work

Shipped products shown as they really look, and live models of the ideas behind the rest: encrypted messaging, anonymous forms, Shine - Photonic Circuit Simulator, a model that infers hidden rules, peer-to-peer RPC, a faster Postgres transport and a gravity-bending game. Each one wears its own colours.

01 / Privacy · End-to-end encryption

Lupyd

Privacy-focused collaboration platform with end-to-end encryption, where the server relays and stores data it cannot read.

02 / Encryption · MLS

Firefly

Open-source Rust MLS (RFC 9420) client for end-to-end encrypted messaging, with SQLite storage, WebTransport and Node.js bindings. Powers Lupyd.

03 / Cryptography · Privacy

Noon

Anonymous forms built on RSA blind signatures: the server verifies every response came from an allowed person, but can't tell who sent which.

04 / Game development · Godot

Infinity

A 3D maze race where any wall can be your floor: switch gravity mid-air to cut through the third dimension. Built with Godot.

07 / PostgreSQL · QUIC

Postgres with QUIC

The PostgreSQL wire protocol over QUIC: a modified pgcat pooler that carries every client as its own QUIC stream over a handful of connections.
