Case Study

Data-Driven Inventory Optimization

Full-Stack Data Analysis

Strategic Sourcing Team

Data Analysis

In my current project, I built a full-stack web application that interfaces with our company's MRP systems to drive smarter inventory decisions. By extracting data with SQL, mapping complex relationships between components using Python’s NetworkX library, and recommending viable alternatives, my work helps reduce slow-moving and obsolete parts. This initiative not only optimizes inventory but also supports a lean, just-in-time strategy across production sites.

Highlights

  • SQL-driven data extraction from MRP systems
  • Network modeling with Python’s NetworkX
  • Development of a full-stack web application
  • Strategic sourcing to reduce inventory of obsolete parts

Interests

Outside of work, you’ll often find me challenging myself on the climbing wall or out on a long mountain hike. Whether it’s an indoor climb or a rugged mountain trail, I see each ascent as a puzzle that challenges both my body and my mind.

I also love camping—spending nights under the stars and enjoy the simplicity. These activities keep me grounded, boost my creativity, and remind me why I love tackling challenges every day.

BACKGROUND

Data and Tech

Technology has been a part of my life since I was little—thanks to my dad and his world of electronics. My fascination with physics naturally led me to study Electrical Engineering, and my early career in embedded systems taught me the ropes.

Somewhere along the way, I discovered the true power of data, which really changed the game for me. Combined with my growing interest in business values and a hunger for bigger challenges, I kicked off my Master’s in Data Science.

And here I am today, living in the fast lane of data and tech, with a lot of passion and motivation. I embrace all the challenges and work on projects I never thought possible-like building this website while running a programming assignment with two deep neural networks in the background (11 March 2025). I'm enjoying every twist and turn alongside an awesome community of friends who share the same passion.
