Syrin LLC
Architecting resilient systems, from offline networks to native mobile experiences.
About Syrin LLC
Syrin LLC is an independent software development studio building high-performance, native iOS and web applications. Founded by Qianyue Ding, a recent graduate from the University of Pennsylvania based in Redmond, WA, the studio focuses on engineering reliable systems that bridge complex backend logic with polished, responsive client interfaces.
Our current development pipeline features three core projects tailored for distinct technical and user challenges. The flagship project is a Python Data Structures and Algorithms platform designed to replace rote memorization with structured problem families, deterministic spacing, and first-principles progression. We are also researching battery-efficient peer-to-peer data synchronization models for offline messaging, alongside a native real-time coordination ecosystem built for live event production.
Our Products
Python DSA & Interview Prep
An opinionated coding platform that replaces rote memorization with structured problem families and spaced repetition, teaching engineers how to adapt algorithms from first principles when interview constraints change.
Low-Power Offline Gossip Protocol
An experimental peer-to-peer messaging architecture that optimizes background radio duty cycles to enable resilient local communication in disconnected environments without devastating mobile battery life.
Run of Show (ROS) Ecosystem
A real-time coordination suite for live event crews combining a Next.js web dashboard with a high-performance native iOS app featuring CRDT state-merging and offline mesh fallback.
