    The Engineer Behind the Code

    I'm a software engineer who cares deeply about building things that actually work—at scale, under pressure, and in production. No hand-waving, just shipping.

    My journey started with a fascination for how systems work together. Today, I build secure web applications for government agencies, experiment with agentic AI workflows, and constantly look for ways to make development more efficient.

    I'm not just a coder—I think in systems. Whether it's designing database schemas, architecting microservices, or setting up CI/CD pipelines, I approach every problem with a holistic view.
