Cover image for Built my first Web3 desktop

Built my first Web3 desktop trading bot this week and it's running . 🟢 Here's what I actually shipped: → Connected to Ethereum mainnet via RPC using Ethers.js → Reads live wallet balances and token data from the chain → Integrated Uniswap V2/V3 router calling swapExactTokensForTokens() to execute real swaps → Understands gas estimation, transaction signing, and contract ABIs → Wrapped the whole thing in a desktop app using Electron.js This isn't a tutorial follow-along. I went through the actual Ethers.js docs, dug into Uniswap's router contracts, and debugged real on-chain calls until it worked. Next step: add multi-chain support (BSC + Arbitrum) and DCA strategy automation. If you need a Web3 developer who builds things instead of just talking about them I'm available for projects.

Cover image for NISHAAN is a decentralized evidence

NISHAAN is a decentralized evidence management system designed to restore trust in the justice system by making digital evidence tamper-proof, verifiable, and anonymous. Problems it solves: 1. Broken chain of custody: Evidence gets altered or mishandled when passed through multiple systems and people. 2. Deepfakes & fake timelines: No reliable way to prove when/where a video was originally recorded. 3. Whistleblower risk: Existing systems can expose identities, discouraging people from reporting crimes. 3. Centralized control risk: Admins in traditional databases can delete or manipulate evidence without trace. Core solution: NISHAAN replaces trust-based systems with cryptographic proof: Stores evidence on IPFS (decentralized storage) Anchors file hashes (CIDs) on Ethereum smart contracts Ensures immutability (evidence cannot be altered) Uses RBAC (Role-Based Access Control) for secure permissions Enables anonymous submissions without identity leaks Preserves original file integrity throughout the legal process Key technical approach Hybrid system: IPFS (files) + Blockchain (proof) Smart contracts enforce strict roles (Admin, Police, Court) “1-click adoption” keeps original file hash intact for whistleblower evidence Client-side EXIF extraction prevents fake/old media submissions Robust Web3 frontend handles wallet/network instability NISHAAN ensures that the exact evidence recorded is provably the same evidence presented in court—without relying on trust, only math.

Cover image for Nishaan is an AI-powered student grievance

Nishaan is an AI-powered student grievance platform that uses Claude Haiku to automate the classification, sentiment analysis, and prioritization of academic complaints. Built with Next.js 14 and Node.js, it features premium dashboards for campus observability, anonymous two-way messaging, and a transparent public feedback board to ensure institutional accountability. Nishaan supports a multi-role platform integrity. Each role in Nishaan has specific permissions and access levels tailored to their responsibilities: HOD (Head of Department): Manages all grievances within their department, assigns tasks to teachers, escalates unresolved issues to the Director, and has the authority to provision new student and staff accounts. Teacher: Handles and resolves grievances assigned to them by the HOD. They also have the option to be assigned as a Hostel Warden to manage hostel-specific issues. Admin / Director: The DIRECTOR is the super-user with full oversight of the entire campus. They handle final escalations, can override any decision, and have full system-wide administrative powers (like auditing all logs and managing all accounts). Alumni: After graduation, students transition to this read-only role. They can no longer submit new grievances but retain access to their historical records and the public transparency board.

Cover image for Project Title: All Projects (Centralized Portfolio

Project Title: All Projects (Centralized Portfolio & AI Management System) 1. The Problem Developers often struggle with two distinct challenges: Portfolio Management: Keeping track of multiple web projects, their source code, live demos, and technical configurations (like environment variables) in a single, organized place. Interview Preparation: Preparing for technical interviews for specific projects. Explaining the architecture, implementation choices, and challenges of a project you built months ago can be difficult without targeted practice. 2. Solution My project is a premium, centralized management ecosystem that serves as both a professional portfolio and an interactive interview coach. It provides a high-end visual dashboard to showcase your work while integrating a powerful AI Interview Agent (powered by xAI's Grok-beta) that helps you master the technical details of your own creations. 3. Key Features Premium Glassmorphic Dashboard: A sleek, modern UI built with React and Framer Motion, featuring dynamic 3D backgrounds (Three.js) and a high-end aesthetic. Full-Stack Project Management: Securely add, edit, and delete projects via a Supabase backend. Store detailed metadata: Descriptions, Key Features, Tech Stacks (categorized), GitHub links, and Live URLs. Secure Env Storage: A dedicated space to keep your project's environment variables (API keys, etc.) for quick reference. AI Interview Agent (Powered by Grok-beta): Interactive Chat: A mock interviewer that "reads" your project's data and asks rigorous technical questions about your architecture and implementation. Topic Analysis: Automatically generates project-specific questions, hints, and ideal answers to help you prepare for real-world interviews. Advanced Search & Filtering
