What I'm looking for

I'm looking to build and operate production AI/ML platforms, especially systems that connect governed enterprise data with forecasting, RAG, agents, and reliable model-serving infrastructure.

At Ador Welding, I’m the sole AI/ML engineer building and operating production systems on Oracle ERP. I delivered a demand-forecasting platform, an Oracle Operations Agent, and a Model Context Protocol server for Microsoft Copilot Studio.

I built an XGBoost forecasting pipeline from 1.1M sales-order lines, improving MAE by about 13% over a moving-average baseline. The platform includes Airflow retraining, MLflow model promotion, Evidently drift checks, FastAPI inference, and self-service forecasting dashboards.

I also built a RAG and tool-calling agent over Oracle data, using pgvector, LiteLLM, local Ollama embeddings, and guarded read-only SQL execution. Moving embeddings on-prem and shifting generation to Claude Haiku removed the hosted embedding dependency and reduced cost to about $0.001 per question.

Earlier, I built Go, Node.js, React, and Angular systems for travel, fintech, telecom, and airline operations at Benzy Infotech, Drake Software Services, Amdocs, and WNS. I bring production backend, data-pipeline, cloud, Kubernetes, observability, and security experience to AI platform work.
