Duc Nguyen · Software engineer

I build the systems around intelligent software.

I work on agent runtimes, code intelligence, and developer infrastructure—the layers that give AI useful context, safe ways to act, and a place in real workflows.

Moving down the stack—from using intelligent systems to designing how they reason, act, and stay useful.

Selected systems / 01—04

Making developers and AI systems more capable.

Four projects across the stack: runtime, application, context, and inference.

Working method

Complex systems, clear boundaries.

  1. 01

    Understand the system

    Read the real path before changing the abstraction.

  2. 02

    Find the useful seam

    Put complexity behind the smallest honest interface.

  3. 03

    Build across layers

    Move from model and runtime through backend and interface.

  4. 04

    Verify behavior

    Test the workflow that matters, not just its implementation.
