Silas Stanley Thomas

Data Analyst/ Supply Chain Analytics/ Business Analyst/ BI Analyst

I'm Silas, a curious data guy in the supply chain field. I earned my MS in Business Analytics from UT Arlington and now work as a Data Analyst at Shoppa's Material Handling, with prior data validation and systems engineering experience at Tata Consultancy Services. I turn messy operational data into forecasts, dashboards, and decisions → SQL and Python doing the heavy lifting, Power BI and Tableau making it visible. Ten years of Jiu-Jitsu and a Black Belt taught me the same thing every clean dashboard does: stay composed, stay sharp, be accurate.

Finding My Voice

My public speaking journey started with Toastmasters, a public speaking organization where members practice speeches, get real-time feedback, and build confidence speaking on their feet. It began back in Mumbai, picked back up with Arlington Nooners, and continues today as an active member of Keller Toastmasters. Years of practice speaking in front of a room has built the confidence, communication, and social instincts I now bring to every presentation and conversation.

The Person Behind the Analyst

I'm at my best around new people. Swapping ideas, hearing how other people think, figuring out what makes them tick. That same curiosity is what pulls me into data in the first place: I don't stop until I've found the actual root cause, not just the symptom.

Lately that's spilled over into content creation on LinkedIn, where I recently crossed 10K followers, sharing what I'm learning, consistently, as I learn it.

Always up for a conversation. About data, about ideas, or just to connect.
