“Console game testing experience focused on controller/input responsiveness (e.g., passing/shooting delays) with bug documentation shared to developers via notes/Excel. Also worked as an AI data tagging agent for an e-commerce LLM and built a Python + OpenAI API micro-tool to pre-label queries, improving labeling throughput by ~30% with a human-in-the-loop QA process.”

“Frontend-focused engineer with startup experience (SmartPath, OPC AI) who owned and evolved an internal React/TypeScript component library treated like OSS—refactoring core form and API wrapper modules for stability, type safety, and smaller bundles. Comfortable diagnosing production issues via logs/API traces and shipping end-to-end fixes with tests and documentation, including internal workshops to drive adoption.”

“Customer-facing AppSec/solutions engineer with experience securing cloud-native AI/LLM deployments on Azure and Kubernetes.
