What I'm looking for

I’m looking for a remote senior software and AI engineering role where I can own features and architecture end to end and work on real products with a strong team. I’d like to combine my backend, full-stack and applied AI experience (LLM agents, RAG, production systems), keep growing in technical leadership, and join a company that values quality, clear communication and long-term impact.

As an Independent Contractor, I build and ship AI-powered features end to end, from React and Next.js interfaces to Python and Node.js services. I design RAG pipelines grounded in application data and develop agent-based workflows using LLMs, tools, and APIs.

At Washmen, I led frontend architecture and helped deliver enterprise applications, optimizing React rendering to support 50% more concurrent users with zero downtime. I also built agentic AI workflows and CI/CD pipelines, and mentored junior engineers.
