Built My Career From Scratch — Let Me Help You Build Yours
I’ve Been Where You Are. Let’s Get You Where You Want to Be
Breaking into the data field is tough — especially when you're aiming for that first role or trying to switch careers. It’s easy to feel overwhelmed, unsure where to start, or stuck in a cycle of self-doubt. What you really need isn’t a perfect background or a computer science degree — you need direction, support, and a roadmap that actually works.
​
I went from washing dishes to leading complex, high-impact data projects — not overnight, but with steady progress, trial and error, and guidance I wish I had early on. That’s why I created this mentorship.
This isn’t about theory. It’s about real-world steps, honest conversations, and personalized support from someone who’s lived it.

If you're serious about making your move into data — whether it’s your first role or a career shift — I’m here to help you get there with clarity and confidence.

About Me
I came to the U.S. as an immigrant with no network, no roadmap — just a dream. I started out washing dishes, mowing lawns, cleaning, and working in restaurants. Along the way, I learned valuable life lessons, built an unwavering work ethic, and developed the resilience to overcome challenges. Today, I’m an experienced Business Intelligence professional, leading complex software applications and data projects that drive strategic decisions and business transformation.
With over 7 years of experience in data analytics, business intelligence, and software engineering, I’ve transformed raw data into actionable insights and managed large-scale projects that solve real-world business problems. My expertise includes Power BI development, data modeling, ETL processes, business process automation, and designing sophisticated data-driven solutions. From entry-level jobs to leading multi-faceted, complex projects, my journey has taught me the power of persistence and continuous learning.
This path wasn’t easy — but it’s proof that with the right guidance, dedication, and focus, you can build a powerful career in data. My mentorship program is tailored to offer you practical, real-world advice and a clear roadmap to accelerate your career growth, whether you're just starting out or looking to level up.
If I can do it, so can you. Let’s work together and turn your career aspirations into achievements.
