At Vest Social Inc., I lead AI and platform engineering for a cloud-native social media platform serving 50K+ active users. I designed LLM-powered content moderation with policy guardrails and human review, and built workflow automations that connect LLM reasoning with backend APIs.

At Verizon Wireless Systems, I developed GPT-4 ticket automation and NLP intent classification pipelines that achieved 92% accuracy. I also automated 30% of inbound customer requests and worked on data pipelines handling 10M+ daily events.

Earlier, at Wawanesa Group and Hartford Financial Services Group, I developed insurance and financial platforms, APIs, and microservices. I also built an AI Trading System and a RAG Knowledge Server using Milvus.
