Software Engineer

• Developed a Python service integrating a large-language model, semantic search, and database lookups to translate natural language queries into privacy-preserving, context-aware data functions, overcoming challenges in schema variance and ambiguity resolution.
• Built client-side data tooling for instant read/write performance, automated tracking and committing of local changes to the server, and reactive updates that drive UI efficiently with support for highly relational data. This standardized the most common data access patterns in our codebase and enabled the development of significantly more powerful features while maintaining sub-50ms response times.
• Designed and built a powerful diagramming tool for model-based systems engineering (MBSE) that supports customizable interface edge paths and an arbitrary number of nested sub-flows of systems to support our system- of-systems systems engineering paradigm.
• Orchestrated E2E testing in CI pipelines with Playwright to reduce regressions during feature development.
• Built an attribute-based access control system, including the administrative dashboard for users to customize access rules, and the underlying security abstraction over PostgreSQL row-level security.
• Led and designed a data migration from MongoDB to PostgreSQL retaining all user data, sanitizing foreign keys, and normalizing data to enable highly connected data models.
• Implemented a library of flexible and accessible React UI components aligned with our design system, improving the consistency of our UI and reducing wasted effort between our design and engineering team
