From ideas to real products.

CSE student building backends, competing at hackathons, and shipping real products.

I’m Karan Raj K R — 18, backend developer, and co-founder of KĀRYO. I build with Python and FastAPI, compete at hackathons, and ship projects across ML, AI, and web. I don’t wait for the right moment — I build to learn, and I learn by building things that actually work.

KĀRYO

Co-founder — Your partner in building online presence

KĀRYO is a digital agency co-founded in Bangalore to solve a simple problem — most local businesses have no online presence, not because they don't want one, but because the process is overwhelming.

We go directly to businesses, understand their needs, and build their online presence from scratch. Websites, social media, Google Business — end to end.

Website Development

Modern, mobile-responsive websites built for speed, trust, and local discoverability.

Online Presence

Google Business setup, Instagram, WhatsApp Business — we handle everything so the business owner doesn't have to.

Fast Delivery

From first conversation to live website in 7–10 days. No agency bloat, no back-and-forth.

Let’s Build Something

I build backends, compete at hackathons, and co-run a digital agency in Bangalore. If you have something worth building — let's talk.
