About Me

I'm a Software Engineer with deep experience building AI-powered products from the ground up — and making sure they work correctly under pressure.

My work spans fraud detection systems, RAG pipelines, NLP extractors, deep learning models, and regulatory analytics platforms — all shipped with observability and quality gates baked in.

I'm drawn to AI products precisely because they break in interesting ways. Model drift, edge-case regressions, latency under load — I've built the pipelines that catch these before users see them. Currently at PwC. MS in CS from UT Arlington.

Testing Approach

Quality is an Engineering Discipline

In AI systems, quality means understanding the full behavioral envelope — model behavior at boundaries, degradation under distribution shift, real failure modes for end users.

I bring software engineering rigor: systematic test case design, code-level investigation, and reproducible bug reporting that helps teams fix issues fast.

Model Observability
Evidently AI + Prometheus + Grafana for AI health
STEP 01
Understand the System Under Test

Study the codebase, trace data flows, identify assumptions. For AI products: understand training distribution and failure modes before writing a single test.

STEP 02
Design Tests That Find Real Bugs

Happy-path tests are table stakes. I design around edge cases, adversarial inputs, latency boundaries, and behaviors product teams often miss.

STEP 03
Document Findings for Action

Clear structured findings with steps to reproduce, expected vs. actual, severity, and investigation direction — not just "it broke."

STEP 04
Close the Loop

Work cross-functionally to verify fixes, update coverage, and surface patterns that inform better design decisions.
