What I'm looking for

I'm looking to build production-ready AI, conversational AI, and scalable web solutions where I can turn business needs into measurable automation, performance, and user-engagement outcomes.

At GotBot AI, I build multi-agent LLM systems with Google Vertex AI and RAG pipelines that deliver low-latency, real-time conversational experiences. I also design secure REST API integrations between conversational agents and enterprise CRM and ERP systems.

I've reduced chatbot fallback rates by 58%, increased confidence by 9%, and improved internal update turnaround times by 25% by refining NLP flows, prompts, guardrails, and training processes. Previously at Outlier AI, I trained and evaluated LLMs through code-based RLHF, red teaming, and technical reviews, maintaining 98%+ evaluation accuracy.

I also build React, WordPress, and MERN web platforms, including serverless applications and SEO-focused client sites. My work spans Python, FastAPI, cloud infrastructure, vector search, and AI products such as a job-fit analyzer and anime discovery engine.
