Hey devs 👋

I'm Sachin — a BCA student, ex-graphic designer, and currently deep-diving into the wild world of data analytics 📊



🧩 Who am I?

Once a creative soul designing logos and layouts 🎨



Now learning to wrangle data like it's my side hustle (oh wait—it is)



Currently juggling distance learning, freelancing, and learning SQL/Python/Excel like my career depends on it (because it does)



🎯 Why I'm here:

To learn, share, and (hopefully) help others making a similar switch

To document my journey from Ctrl+Z to SELECT * FROM life

To get roasted (constructively) on my dashboards and queries



🛠️ Tech I'm Learning:

SQL (slowly but surely)

Python (trying not to break it)

Excel (a.k.a. the OG tool)

Data Viz tools (Power BI/Tableau)



💬 Random facts:

I love clean dashboards, black coffee, and sarcasm



I once taught 10th graders basic computers during my 12th board prep. Stress was real.



GPT yells at me for being lazy—and it’s right



Let’s connect! Drop your favorite learning resource or share your data journey in the comments 👇

Excited to be here 🙌
