Bridge — Student Decision Intelligence Platform
↗Next.jsReact NativeAWSStage EngineAIUser Research
Founded to help students navigate high-stakes decision windows before they close.
Identified the problem from personal experience. Ran structured research with 200+ students and SJSU's ISSS office. Built a stage-aware engine that surfaces the next critical action per user journey. Killed the social features when they diluted the core.
The insight: one missed step — a CPT deadline, an OPT window — can change your entire trajectory. Bridge's risk intelligence layer flags these before they close, not after.
Shipped 25+ features across web and mobile. Early access waitlist live.

Regret Analysis — Decision Research
↗PythonNLPReddit APIData ScienceBehavioural Research
Analysed 21,800 Reddit posts across career, relationships, and education to model when and why people reverse high-stakes decisions.
Key findings: regret peaks differ by domain — career regret surfaces fastest, relationship regret surfaces latest. Inaction regret outweighs action regret 2:1 in long-horizon decisions.
These findings directly inform Bridge's risk intelligence design, the system is built around the actual timing of when decision windows close in real student journeys, not assumed timelines.
