Computational neuroscience, from the inside out.

I study computer science and psychology at Purdue, and I build the systems that keep the science — and the path into it — inspectable. Polaris is the production life system. Shared Brain is the research graph. Before that, I shipped software on Azure AD Identity Governance at Microsoft.

Polaris

Local-first native macOS life system — a production surface, not a sketch. Questline DAG engine, SwiftData persistence, Plaid-backed finance, and hubs for mental health, household, and a stardust economy. Where plans become daily execution.

Production systemsSwiftUI / macOSSwiftDataDAG enginePlaid

Questline DAG resolver: cycle detection, topological order, execution frontier, multi-parent unlock, stardust/XP on complete
Plaid Link companion (Express) — token exchange, transaction sync with cursors, Keychain rehydration, production OAuth
SwiftData bridges for tracks and questline blueprints; domain stores for mental health, household, personal care, finance, economy
Shipped shell: Dashboard, Mental Health, Personal Care, Household, Questlines, Shop, Map, Finance

Questline DAG

Cycle-checked topological unlock. Completing Q2.2 opens both children; Q2.5 waits for every parent.

Shared Brain

Dark-mode research dashboard — an interactive neural map for computational psychiatry, methods, and papers. The live graph sitting on top of the Academics vault.

Active buildNext.jsReact FlowKnowledge GraphResearch Infra

xyflow neural map with core/term nodes, filters, layout, import/export, session timeline
Research injectors: freeform nodes, DOI → Crossref metadata, voice-to-node
Seeded on schizophrenia transcriptomics + computational pipeline; open to the wider research graph

In balance

Small E/I-balance sketch on this public edge — tune the metaphor. The full Shared Brain surface is the editable research graph in the app.

Plans

Trajectory layer from the Academics vault — Plan A (US research path), Plan B (international contingency), applicant profile, and skill development toward computational neuroscience.

Living docsPhD PrepPlan A / Plan BSkillsPurdue

Plan A: strengthen the CS / psych profile at Purdue, REUs, applications aimed at the Fall 2027 computational neuroscience cycle
Plan B: international contingency (Mexico / Europe) — transcripts, networking, fellowship scouting
Skill track: Python scientific stack, networks from scratch, Git, viz, MATLAB for neuro labs

Academics vault

Obsidian second brain for the academic career — degree plan, phd-prep, literature, and concept notes spanning Purdue Fort Wayne CS & Psychology and the computational neuroscience through-line. The durable substrate Plans and Shared Brain both draw from.
