Hi! I’m Sai Krishna — a passionate teacher and software engineer who loves helping students grow in **Data Structures, Algorithms, Competitive Programming and Mathematics for Data Science**.

I’ve solved over **1000 DSA problems** and hold a **4-star rating on both CodeChef and GeeksforGeeks**. I completed my **Master’s in Computer Science from IIT Kharagpur** with an **All India Rank 55 in GATE**, and I worked as a **Full Stack Developer** in a product-based company with over **1.5 years of industry experience**.

Teaching has always been close to my heart. I’ve guided students both **online and offline**, and worked as a **Teaching Assistant** at **IIT Kharagpur** and the **University of Hyderabad**. I’ve taught **OOPs with C++** to a student studying in Germany and **DSA, Probability & Statistics, and Linear Algebra** to a postgraduate student at **IIIT Hyderabad**. I also had the privilege of teaching **PRMO-qualified students** in a government-organized **RMO workshop**, alongside professors from the University of Hyderabad.

My teaching style focuses on making students *think like problem solvers*:

1. I give **practice problems** and encourage students to try them on their own first.
2. If they get stuck, I help them **observe patterns and hidden insights** in the problem statement.
3. I share **concise notes** that serve as valuable long-term learning material.
4. I always write **well-commented code**, so revision becomes clear and effortless.

I truly enjoy seeing my students improve and gain confidence in solving challenging problems. For me, teaching isn’t just about concepts — it’s about helping students **develop the right mindset** to grow as independent thinkers and coders.
