About

"Problem-Solver with Passion" My passion for problem-solving led me to the exciting world of Data Science. I'm driven by a deep curiosity for uncovering insights that transform businesses and change lives. I have a talent for transforming data into compelling narratives that drive actionable decisions. As a Data Science and AI Consultant, I worked on LLM models with GPT to create image captioners, and meme generators for the WhatsApp chatbot(Jobot), and also worked with Langchain database models. At Flux. chat, I built ETL Data pipelines, analyzed data, and created insightful automated live reports and dashboards. Throughout my journey, I've witnessed how data can drive positive change, from predictive modeling to data-driven marketing insights and I chose to be a lifelong learner.
