Over the past 3 years, I have advanced from core development tasks to leading mid-level pipelines in AI implementation and advanced statistical analytics. I specialized in production-ready AI solutions, custom model enhancement, and structural data modeling.Key Achievements & Responsibilities:Production-Grade AI & RAG Deployment: Designed and optimized scalable Retrieval-Augmented Generation (RAG) pipelines, integrating vector databases to achieve a 25% reduction in model hallucinations for enterprise clients. End-to-End Model Fine-Tuning: Conducted data preprocessing, Supervised Fine-Tuning (SFT), and RLHF alignment for open-source LLMs, ensuring strict domain compliance and higher factual accuracy. Advanced Statistical Analytics in R: Engineered complex data visualization dashboards and predictive models using R (ggplot2, tidyverse), translating messy datasets into actionable, publication-quality business insights.
