I build backend APIs, real-time systems, and LLM-powered applications at enterprise scale.
United StatesWhat I'm looking for
I've built backend services and real-time transcription systems for Halliburton through ILink Digital, using Node.js, Hapi, Joi, and PostgreSQL. I migrated audio transcription to Socket.IO chunked streaming, resolving upload failures affecting 40% of sessions and removing WAF request-size bottlenecks.
I architected multi-tenant REST APIs supporting 150+ daily SQL queries with tenant-scoped access control and 99.2% uptime. I also built LangSmith evaluation workflows for LLM-generated SQL and model responses, while partnering with development and QA teams on reliability and releases.
More recently, I've supported OpenAI's robotics data-collection lab through Apex, collecting, cleaning, labeling, and validating robotic-arm sensor and operational data for AI/ML training. My projects also include LangChain and LangGraph multi-agent workflows, ETL pipelines, machine-learning cost prediction, and a MERN e-commerce application.
