Senior Full Stack AI Engineer at Fieldtech who cut application latency by 64% and advanced agentic AI workflows.

At Fieldtech, I cut application latency by 64% with Next.js and React, improving response times from 300ms to 100ms. The application now handles 8K requests per day.

I accelerated agentic AI workflows and autonomous AI systems using OpenAI and Claude Code for regulated industries and Fortune 500 clients. I also directed a migration from a monolithic system to microservices, reducing deployment time and annual costs.

At QStart Labs, I optimized AI systems with scikit-learn and TensorFlow and developed backend services using Node.js and Anthropic Claude. I also migrated data from MySQL to PostgreSQL, reducing retrieval time from 25 seconds to 5 seconds.

Earlier, at Switchbox Inc, I built a full-stack application using Python, Django, React, and Next.js, with OpenAI and Claude Code for natural language processing. I also worked on data processing with PostgreSQL and Apache Spark.
