Hello, I'm

Data Scientist with Advanced Data Engineering & Business Analytics Expertise

Data Scientist with 3+ years of experience applying advanced data science and analytics to marketing and financial product domains. Specializing in campaign measurement, causal inference, econometrics, and ROI-driven optimization with proven results in campaign performance and retention.

AboutMe

My journey into data science began with a simple question: "What if we could predict the future?" This curiosity led me down a path where I discovered that data isn't just numbersβ€”it's stories waiting to be told. I've spent the last few years transforming complex datasets into actionable insights that drive real business impact.

What excites me most is the challenge of finding causality in a world full of correlation. I love diving deep into sophisticated statistical methods, but I'm equally passionate about making complex concepts accessible to everyone. As a lifelong continuous learner, I'm always exploring new methodologies and staying current with the latest developments in data science. Whether I'm building advanced causal inference models or teaching others through my blog, I believe knowledge should be shared and understood.

My vision is to bridge the gap between cutting-edge data science research and practical business applications. I want to help organizations make better decisions through data, while also contributing to the data science community by sharing what I learn along the way. The future of data science is collaborative, and I'm excited to be part of that evolution.

Personal Interests

When I'm not diving deep into data science, here's what keeps me inspired and energized:

🎡Music & Singing

I love to sing and explore different genres. Music helps me think creatively and find new perspectives on problems.

πŸ“šHorror Books

There's something thrilling about a good horror novel. It keeps my mind sharp and my imagination active.

πŸš—Long Drives

Nothing beats a long drive with good music. It's my way of clearing my mind and getting fresh ideas.

πŸ₯ΎHiking & Nature

Hiking helps me disconnect from technology and reconnect with nature. Great for problem-solving and reflection.

πŸ‘¨β€πŸ³Cooking

Cooking is like data science - you experiment, measure, and create something amazing from raw ingredients.

🎯Team Collaboration

I thrive in group settings and love being a team player. I'm also comfortable working independently when needed.

πŸ˜„Sarcastic Humor

I bring a joyful and sarcastic perspective to everything. Life's too short to take everything seriously!

πŸš€Continuous Learning

I'm always exploring new technologies and methodologies. The data science field never stops evolving.
