🛠️ How I Worked
Sole designer across the full lifecycle — business requirements, wireframes, hi-fi specs, and QA documentation. Led cross-functional reviews with engineers, BAs, and compliance teams across 8 sub-modules over 1.5 years.
🚀 What Shipped
A unified interaction system deployed to 1,800 schools — one consistent pattern that scaled from 8 sub-modules to 12+ without redesign.
OASIS is the student information system for New York City's K-12 public schools — the largest school district in the United States. The Confidential Services module handles foster care placements, temporary housing, orders of protection, missing children reports, and meal eligibility.
Project structure
The legacy systems
Before OASIS, staff relied on ATS — a command-line interface with text-based navigation — and STARS, a basic Windows application with simple forms. Neither was designed for modern compliance requirements.
The daily reality
A school admin processing a foster care placement might check one system for housing status, another for orders of protection, and a spreadsheet for meal eligibility — all while ensuring privacy compliance across disconnected tools.
Eight categories from foster care to meal codes — each with its own data model, compliance rules, and edge cases. All needed to feel like one product.
Three roles touch the same data but need entirely different views, permissions, and workflows. One-size-fits-all would fail usability and privacy.
Each sub-module had its own compliance team, SMEs, and DOE program office — aligning them required constant communication and iterative reviews.
Challenge
Eight sub-modules with different data types could easily become eight separate products. Staff deal with high-stakes, time-sensitive situations — relearning the interface for each record type adds cognitive load where it matters most.
Solution
I designed a consistent pattern — list view → detail page → add/edit → history — across all 8 sub-modules. Staff who learn one category can navigate any other without retraining. This pattern later scaled to 4+ additional modules.
List → detail → add/edit → history
Different modules, same pattern
Challenge
Meal code compliance lived in standalone PDFs, per-school spreadsheets, and manual cross-referencing. Center users had no aggregated view — they checked compliance school by school, manually cross-referencing PDF reports.
Solution
I redesigned the information architecture into role-appropriate views:
Teachers · Classroom
Meal eligibility records — just what they need to respond in the moment.
School Admins · Building-wide
Complete meal code data — update records, resolve discrepancies, run reports.
Center Users · Multi-school
Aggregate compliance dashboard — drill down to any school when needed.
Challenge
The original guardian information design worked for simple cases — one or two guardians. As requirements grew, more guardian types and fields needed accommodating. The initial layout couldn't absorb the growth.
Solution
I redesigned guardian info as structured cards: name and actions at top, scrollable detail area, clear separation between entries. Whether one guardian or six, the layout stays organized and scannable.
Structured cards that scale with data
What previously required navigating 5-6 separate screens now lives in one unified interface.
The interaction model designed for 8 sub-modules scaled to 4+ additional modules without redesign.
Staff trained on one category could navigate all others immediately — because every sub-module follows the same pattern.

Cognitive load isn't just a UX problem — it's a safety problem. Shared patterns mean staff focus on the student, not the interface.
Different compliance teams for each sub-module meant defining the right problem depended on asking the right questions. Review decks became the alignment tool.
Federal and city regulations shaped every default state and permission level. Privacy wasn't a constraint — it was a core design material from the start.
