Hi! I'm a full-stack developer, and most of my work now is bots for crypto communities on Telegram and Discord. It started with my own bot. I was tired of checking charts all day, so I built one that answers price questions and pings me when a coin hits my target. Friends in a few groups wanted their own, and now that's what I do. What I can build for your group: - Price and alert bots: 10,000+ coins, % alerts, chart images, daily briefs - Token gating: members verify their wallet by signing a message and get the holder role - Buy and whale alerts posted to your channel - Giveaways, moderation, anti-scam filters, custom commands I like to show before I sell, so I'll run a short demo in your group first. The price is fixed before I start and paid through LaborX escrow. You get the full source code and 30 days of fixes. I also take web, backend and automation jobs (TypeScript, Node.js, React, Python). Fast replies, simple process.
