Expert in Python, Java, AWS | 9Yrs Exp.| Mentored 1000 hours on Scaler
I love building high-impact products that push me to think creatively and solve complex problems. I have designed and developed large-scale, highly available systems from scratch, delivering high-throughput, fault-tolerant applications that serve millions of users.
My expertise spans Java, NoSQL, Serverless Computing, and distributed systems, with a strong focus on scalability and reliability. I’m equally passionate about mentoring, having guided 100+ students and professionals in DSA, system design, and interview preparation.
