Cover image for Developed an advanced, full-stack multi-agent
Developed an advanced, full-stack multi-agent AI orchestration system inspired by modern office simulation frameworks, tailored specifically for cybersecurity research and automated bug hunting. The platform features a Dual-Department architecture split into a Cyber Crime Branch (Digital Forensics & OSINT) and a Bug Bounty Lab (AppSec & Recon), managed by an autonomous Chief Orchestrator ("Michael"). Equipped with deterministic verification nodes to eliminate hallucinations and ensure 100% reliable security findings.

Cover image for 🚀 Excited to launch my
🚀 Excited to launch my latest full-stack project: The Dual-Department AI SOC & Bug Bounty Command Center! Are you tired of standard, boring security dashboards? I built a fully automated, gamified multi-agent platform that brings AI security operations to life using a 2D Pixel-Office simulation. The system acts like a real-life virtual cybersecurity firm with 11 specialized autonomous agents, split into two distinct departments: 🛡️ 1. Cyber Crime Branch (Forensics & OSINT): Automated EXIF metadata & GPS extraction from media files. Email header hop tracing & SPF/DKIM verification. Public username footprinting & threat intel reputation lookups. 🎯 2. Bug Bounty & AppSec Lab (Recon & Vulnerabilities): Live subdomain asset mapping & JS endpoint extraction. High-entropy regex scanning for exposed API keys & JWT secrets. Deterministic security misconfiguration audits (CORS reflection, Clickjacking, & Origin IP leaks). ✨ Key Highlights: Real-time 2D Visuals: Built with Next.js and Phaser.js v3, where character sprites walk to their assigned desks, work on live terminals, and take coffee breaks during idle states (synced via WebSockets at 60fps). Zero False Positives: Powered by a LangGraph & FastAPI backend featuring a dedicated PoC Verifier Node that runs deterministic Python checks before compiling final reports. Live Terminal Stream: Integrated xterm.js drawer to monitor agent stdout/stderr logs in real time. 🛠️ Tech Stack: Python 3.11, FastAPI, Async Socket.io, LangGraph, Next.js, Phaser.js v3, xterm.js. Perfect for developers, security enthusiasts, or teams looking to integrate gamified multi-agent automation into their security workflows! 📂 Interested in getting the complete source code or setting this up?

Cover image for Role: Backend Developer (Node.js, Express.js,
Role: Backend Developer (Node.js, Express.js, MongoDB, REST APIs) ScrapBag is a startup that enables users to sell scrap online through a seamless pickup and payment experience. I was responsible for developing the backend services that powered the customer platform as well as the internal fleet management system. For the customer application, I built scalable REST APIs for user authentication, scrap pickup requests, order management, and wallet transactions. When a user scheduled a scrap pickup, the system automatically created an order and assigned it to the operations workflow. I also developed the backend for the fleet management platform used by drivers and field executives. Each driver was associated with a vehicle and could view assigned pickup requests, navigate their collection route, update pickup status, and mark orders as completed in real time. Once a pickup was successfully completed, the backend calculated the scrap value, updated the order status, and automatically credited the customer's account with the corresponding amount. This ensured a smooth end-to-end workflow from booking a pickup to receiving payment.

Cover image for I developed a modern CRM
I developed a modern CRM platform that helps businesses manage leads efficiently through a centralized dashboard. The application enables users to organize their sales pipeline, upload lead data in bulk, and quickly search, filter, and manage customer information. I built responsive and reusable user interfaces using Next.js, React, and Tailwind CSS, with a strong focus on performance and user experience. The platform leverages Server-Side Rendering (SSR) for improved SEO and faster page loads, while code-splitting and lazy loading reduce the initial JavaScript bundle for a smoother experience.
