Harsh Kadyan — Full Stack Developer & AI Engineer

Harsh Kadyan — known online as BrutalHarsh — is a 21-year-old full stack developer and AI engineer based in Rohtak, Haryana, India. He builds full stack web applications, backend APIs, AI/LLM integrations, automation tools, Chrome extensions, and Discord bots for clients worldwide. Over the last few years he has delivered 100+ freelance projects across Python, JavaScript, TypeScript, Node.js, React, and Next.js, and he runs four personal websites: thedevs.org, thedevscourse.com, brutalharsh.me, and harshkadyan.com.

As a full stack developer, Harsh works across the whole stack — frontend apps in React and Next.js, backend APIs in Node.js and Express.js, database design in MongoDB, PostgreSQL, MySQL, and Redis, and cloud infrastructure on AWS with Docker and CI/CD pipelines on Linux. His primary languages are Python and JavaScript/TypeScript, and he specialises in AI and LLM integration: building AI agents, wiring GPT and Claude into production systems, prompt engineering, RAG (retrieval-augmented generation), and backend tooling for AI platforms.

Harsh currently holds three roles. He is a Backend Developer at Megallm (megallm.io), an AI/LLM gateway that gives developers unified multi-model API access to many models through one API. He is Product Manager at Ghostpay (ghostpay.org), a fintech platform building digital wallet infrastructure and payments. And he is a Backend Developer at TabTrips (tabtrips.com), a B2B travel and hotel booking platform with a hotel booking engine and travel APIs. On top of these, he takes on freelance work through thedevs.org, his software development agency that builds iOS, Android, Mac, and Windows apps, Discord and Telegram bots, websites, landing pages, startup MVPs, browser extensions, scripts, DevOps, hosting, and domains.

Through thedevs.org, Harsh and his team ship any tech work a client posts — from a single automation script to a full startup. thedevscourse (thedevscourse.com) is his online learning platform for Python, web development, AI prompt engineering, Git and GitHub, and deployment, with interactive exercises and AI tutoring. brutalharsh.me is his personal brand and handle hub, and harshkadyan.com is his main portfolio, CV, and contact site.

His project portfolio reflects this range. Brutal Bot is a multipurpose Discord bot built with Discord.js and Node.js with 500+ commands for moderation, entertainment, automation, and utilities. AstroScope is an intelligent Discord bot for personalized astrological readings, daily horoscopes, birth-chart analysis, and compatibility reports. TwoFactorAuth is a macOS SwiftUI app that generates TOTP codes (SHA1/SHA256/SHA512), works offline, stores secrets in Keychain, scans QR codes, and imports from Google Authenticator. Knodor (knodor.com) is a society and estate management platform for gated communities with visitor gate security, billing, notices, a marketplace, and safety across Web, iOS, and Android.

Harsh is pursuing a BCA (Bachelor of Computer Applications) at Maharshi Dayanand University (MDU) in Rohtak. He speaks English and Hindi, works with clients worldwide, and communicates through a dedicated project chat with daily progress updates. His approach is pragmatic and production-focused: scalable backends, secure authentication, clean APIs, and AI features that actually ship.
