About
I am a Data Science Manager and AI practitioner with 8+ years of experience across data science, machine learning, analytics, and AI. My work ranges from building machine learning solutions to leading AI initiatives and turning business problems into practical data and AI applications.
I have also written 500+ articles across platforms such as KDnuggets, Machine Learning Mastery, Towards Data Science, and Non-Brand Data. More recently, I co-authored Python Data Analysis, Fourth Edition, covering Python analytics, machine learning, GenAI, LLMs, and data engineering.
Through mentoring, I want to help professionals who are transitioning into Data Science and AI, building their skills, or trying to understand what they should focus on next in their career.
My mentoring style starts with understanding where you are now and what you want to achieve. From there, we can build a practical plan around your skills, portfolio, career direction, or technical challenges. I prefer an open conversation where we can discuss what is working, what is not, and what you can realistically do next.
If you want an outside perspective on your Data Science or AI career, feel free to reach out.
