Responsibilities

Logic Deconstruction & Translation:
Reverse-engineer legacy Stored Procedures to determine how user permissions, entitlements, and roles are calculated, translating that logic into modern, Zero Trust–aligned identity and access models.
Data Architecture & Modeling:
Design and maintain logical and physical data models that support identity, authorization, and access use cases, including mapping complex relational schemas to flat or attribute-based identity profiles.
Custom ETL & Integration Development:
Design and build custom data extraction and transformation routines using T-SQL and scripting languages (Python/PowerShell) to migrate and integrate data from Sybase into Okta and related platforms.
Performance Optimization:
Analyze and optimize stored procedures, queries, indexing strategies, and data pipelines to ensure scalability, reliability, and performance in high-volume and mission-critical environments.
Data Security & Compliance:
Implement database-level security controls, auditing, encryption, and least-privilege access patterns in alignment with Zero Trust principles and federal security requirements.
Technical Content Creation:
Produce high-quality technical documentation, architectural diagrams, and repeatable migration recipes to guide developers and stakeholders through the new identity data structures.
Solution Design & Requirements Translation:
Translate business, security, and IAM requirements into scalable SQL and data integration designs that support HUD Zero Trust objectives.
Developer Engagement & Technical Leadership:
Collaborate with product, engineering, and security teams; provide architectural guidance; conduct code reviews; and mentor developers to promote consistent, high-quality data solutions.
Data Validation & Reconciliation:
Develop reconciliation and validation scripts to ensure 100% data integrity between legacy Sybase systems and target identity platforms.
