  1. WorkJun 2026 – PresentHerndon, VA

    Software Engineer

    Exostar

    A FedRAMP-certified platform where defense manufacturers exchange Controlled Unclassified Information with their suppliers. First engineering role, on the authorization and tenant-isolation side of the product.

    • Eliminated a privilege-retention flaw that let demoted or removed users keep old permissions until logout, by moving authorization from a login-time cookie claim to a live per-request role check.
    • Closed a cross-tenant data-leak path by resolving file uploads from the thread's owning organization instead of the uploader's membership.
    • Re-architected the tenant-admin permission model across the API, SQL schema, SAML login, and Angular UI, shipped with guarded migrations and ordered rollback.

  2. ResearchJan 2026 – Present

    Lead Researcher, Audio-Visual Engagement Detection

    San Francisco State University, advised by Prof. Sanchita Ghose

    The first audio-visual fusion result on the EngageNet benchmark (11,206 clips, four levels of student engagement). Every published baseline is video-only.

    • Best model reaches 66.36% top-1, ahead of four of six published baselines.
    • Gained +2.03 accuracy at zero training cost by swapping argmax for ordinal calibration decoding on identical weights, a bigger win than every architecture and optimizer change combined.
    • Shipped the trained models as an inference pipeline and Streamlit UI, verified bit-exact against the training arrays.

    AI Engineer, Curriculum-to-Job Matching Engine

    San Francisco State University, with Prof. Tracy Chen

    An engine that connected 100+ real job postings to student skill profiles and coursework models. Improved curriculum alignment by roughly 30% in pilot evaluations.

    • Architected the LangGraph ingestion pipeline in Docker.
    • Hybrid data layer: Qdrant embeddings plus PostgreSQL metadata, powering semantic search, matching, and skill-gap analysis.

  6. ProjectApr 2026

    Rodex, a multi-agent code review IDE

    Agent framework written from scratch

    No LangChain, no LangGraph: a base-agent abstraction, event bus, sandbox manager, and shared drive coordinating four specialist reviewers, streaming every thought and finding live over SSE into a Cursor-style editor.

    • Specialists get MCP tools (filesystem, git, fetch) under per-agent allowlists.
    • Autonomous fixes are gated behind sandboxed compile checks and validated against a seeded suite of four vulnerability classes.
