What I'm looking for

I want to build production-grade LLM/RAG systems that automate document and information workflows. I’m excited by roles where I can own APIs and pipelines end-to-end, improve accuracy and reliability, and measure impact like reduced manual review and better matching.

I’m an AI Engineer with 1.5+ years of experience building production-grade AI systems—especially LLM pipelines, intelligent document processing, and RAG-based retrieval architectures. At UNIPREP, I developed a resume parsing system processing 500+ documents with >90% field extraction accuracy.

In my current role, I built an end-to-end CV parsing system using OCR, NLP, and LLMs, achieving >90% structured field extraction accuracy across 5000+ resumes processed. I engineered RAG pipelines with LangChain, OpenAI APIs, FAISS, and Chroma to reduce manual review time by ~40%.

I focus on reliability and measurable impact: I apply prompt engineering strategies (chain-of-thought, few-shot) to improve extraction consistency and reduce hallucination rates. I also build FastAPI microservices and automate workflows, cutting communication overhead by 30%.

Before that, I worked as an Executive – Product Design (AI/Data Focus), applying Python-based data analysis and ML to elevator fault datasets, supporting a simulated 15–20% reduction in unplanned downtime. I bring the same hands-on, cross-functional mindset to every AI solution I ship.
