01 — About

Building Systems
That Think

I'm a Data Analyst and AI/ML Engineer based in Bangalore, India, with a deep passion for building end-to-end intelligent systems. Someone who enjoys translating complex, ambiguous problems into scalable, high-impact solutions

My journey spans from architecting agentic Voice AI platforms handling outbound calls & executing real-time actions (appointments, reservations, and payments) at a startup to driving multi-million dollar retail analytics initiatives at Lulu Group International.

I specialize in the full pipeline — from processing millions of records using PySpark, to deploying LLM-powered applications and real-time data systems. I thrive at the intersection of AI and business impact, turning large-scale data into measurable outcomes.

Beyond code, I'm a Tabla player with a senior diploma in Hindustani classical music, an IEEE-published researcher.

What shapes the way I think — creativity, community, and craft outside the IDE.

Playing Tabla

Music & Art

🥁 Hindustani Tabla

Completed my Senior Diploma in Hindustani Tabla — a journey of over a decade mastering one of India's most rhythmically complex classical instruments. Performed on multiple stages, exploring the intersection of discipline, rhythm, and creative expression that quietly informs how I approach complex systems.

Student Workshop

Teaching & Mentorship

🎓 Giving Back to Students

Conducted hands-on workshops for students on AI/ML concepts, data pipelines, and real-world problem solving. Passionate about demystifying complex technology and empowering the next generation of engineers to build things that matter — the same way mentors did for me.

Surfing

Sports

🏄‍♂️ Surfing the Open Blue

Surfing in the open ocean is where I feel most alive — reading waves, adapting to ever-changing conditions, and finding balance in motion. It’s a constant lesson in patience, resilience, and control under uncertainty — principles that directly shape how I approach building and problem-solving.
