What I'm looking for

I'm looking for a data analytics or AI-focused role where I can turn data into actionable insights, build dashboards and AI-driven solutions, and grow through hands-on work with Python, Power BI, machine learning, and LLM applications.

I've supported data-driven decision-making at Glow Logics Solution by cleaning and analyzing datasets, building machine learning models, and creating Power BI and Excel dashboards. At Ethara AI, I've evaluated LLM outputs, refined prompts, annotated datasets, and helped improve chatbot workflows and model reliability.

I've also built AI-powered analytics products for sales performance, business intelligence, and product analytics, using natural-language querying, interactive visualizations, KPI tracking, and AI-driven recommendations.
