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.

🚚 Case Study: Built a live driver-ops platform for a UK logistics company Just shipped a project I'm genuinely proud of a driver mobile app + admin dashboard for EC Logistics, a UK-based logistics operator. The problem: their drivers were tracking shifts, expenses, and delays manually no live visibility for the office, slow expense approvals, and no single source of truth. What we built: 📱 Driver App (iOS + Android, live on both stores) • Start/end shift with live GPS tracking (even in background) • Snap & submit expense receipts and delay evidence on the spot • Real-time chat with the office • Push notifications for approvals and updates 🖥️ Admin Console • Live driver map with route history • Expense approval queue with an AI layer that flags invalid/suspicious receipts automatically • Configurable auto-approval rules by category, time window, and spend limit • Xero integration for accounting sync • Audit logs, broadcast messaging, and per-driver chat • Delay and shift history reporting Stack: mobile app + backend services, real-time location pipeline, AI-assisted receipt review, and a full admin web console. The result: the office now approves expenses in minutes instead of days, gets live visibility into every driver on shift, and has an audit trail for everything. 📲 App Store: https://apps.apple.com/us/app/ecl-driver/id6793643563 I run an agency building production-grade mobile apps, dashboards, and backend systems for logistics, fintech, and SaaS teams. If you need something similar an ops dashboard, a driver/field-worker app, or backend systems that actually hold up in production let's talk. 👉 Hire me on Fiverr: https://www.fiverr.com/s/jyjLeWm (https://www.fiverr.com/s/jyjLeWm)Or message me here on Contra happy to scope your project.
