About
About Harsh Kadyan
I'm Harsh Kadyan — known online as BrutalHarsh — a 21-year-old full stack developer and AI engineer based in Rohtak, Haryana, India. I design and ship production systems end-to-end: backend APIs, frontend apps, database design, cloud infrastructure on AWS, Docker containerisation and CI/CD pipelines. My primary languages are Python and JavaScript/TypeScript, with deep day-to-day work in Node.js, React and Next.js.
I specialise in AI/LLM integration — building agents, wiring GPT and Claude into production systems, and building backend tooling for AI platforms. As a backend developer at Megallm I work on a unified multi-model LLM gateway; as product manager at Ghostpay I help shape fintech wallet infrastructure and payments; and as a backend developer at TabTrips I build the B2B hotel booking engine that powers this very site.
Beyond roles, I've delivered 100+ freelance projects — automation tools, Chrome extensions, backend scripts, API integrations and custom web applications — and I run four personal websites: my agency thedevs.org, my learning platform thedevscourse.com, my personal brand brutalharsh.me, and my main portfolio harshkadyan.com. I'm currently pursuing a BCA at Maharshi Dayanand University (MDU), Rohtak, and I'm open to remote full stack, backend and AI engineering work worldwide.
