About

โžฃ What if complex tech concepts were explained so clearly that even a 15-year-old could understand them? Thatโ€™s the problem Iโ€™m obsessed with solving. ๐—ช๐—ต๐—ฒ๐—ฟ๐—ฒ ๐—œ ๐—ฐ๐—ผ๐—บ๐—ฒ ๐—ณ๐—ฟ๐—ผ๐—บ I come from a background where good guidance was rare and self-doubt was commonโ€”especially for students from Tier-3 colleges. I learned early that talent alone isnโ€™t the issue. Clarity, confidence, and the right mental models are. Over the last 3+ years, Iโ€™ve worked as a Software Engineer, building scalable backend systems and production-grade solutions using Java, Kotlin, Python, SQL, Git, and Androidโ€”first at Amazon, and now at Google. But while writing code was my job, breaking down complex ideas slowly became my craft. ๐—ช๐—ต๐—ฎ๐˜ ๐—ฑ๐—ฟ๐—ถ๐˜ƒ๐—ฒ๐˜€ ๐—บ๐—ฒ ๐˜๐—ผ๐—ฑ๐—ฎ๐˜† Today, Iโ€™m a Software Engineer at Google (Android) who genuinely enjoys teaching more than impressing. I specialize in: โ€ข Explaining AI / ML / RAG concepts in plain English โ€ข Making DSA & interview prep feel logical instead of scary โ€ข Turning complex system thinking into simple stories and questions โ€ข Helping Tier-3 college students believe they can crack Big Tech I create content where: โ€ข No jargon is thrown casually โ€ข Concepts are explained using stories, real-world analogies, and first principles โ€ข Confidence is built before complexity ๐—ช๐—ต๐—ฒ๐—ฟ๐—ฒ ๐—œโ€™๐—บ ๐—ด๐—ผ๐—ถ๐—ป๐—ด I want to build: โ€ข A trusted learning ecosystem around AI, DSA, and interviews โ€ข Content that removes fear from tech and replaces it with clarity โ€ข A generation of engineers who think deeply, not just memorize solutions ๐—Ÿ๐—ฒ๐˜โ€™๐˜€ ๐—ฐ๐—ผ๐—ป๐—ป๐—ฒ๐—ฐ๐˜ If youโ€™re: โ€ข A student looking for clarity and confidence โ€ข An engineer trying to understand AI or DSA deeply โ€ข Someone who believes learning should feel simple, logical, and human ๐Ÿ‘‰ Follow me here on LinkedIn ๐Ÿ‘‰ Check out my YouTube/blog content ๐Ÿ‘‰ Or DM meโ€”I genuinely reply when I can Letโ€™s make complex tech feel simple. ๐Ÿš€
