    Hi, I’m Michael, CEO at Aegas — a no-nonsense web3 development partner. We don’t just write smart contracts; we build solutions that actually make your project work. DeFi, Web3, GameFi — you name it, we’ve delivered it. Oh, and if you’re looking for a “dev shop,” swipe left; we’re in this for the long haul, like your technical co-founders who don’t take equity. Here’s how we solve the problems keeping you up at night: 🚑 For Web3 Startups: “Why does hiring devs feel like rolling dice at the casino?” We help you skip the chaos with battle-tested processes and clean, scalable code. You get a reliable product — not just a pile of GitHub commits. 🚀 For DeFi Founders: “How do we stop our tokenomics from falling apart after launch?” We create systems (staking, farming, cross-chain solutions) that boost adoption and liquidity without tanking your project. 🎮 For GameFi Visionaries: “Can this actually be fun and work on-chain?” Yes, it can. And we make sure it does. From NFT marketplaces to full-blown blockchain gaming ecosystems, we deliver platforms that excite users and investors alike. 💡 Here’s What We Do Better Than the Guy You Hired Last Time: - DeFi Infra: Launch staking, lending, and farming features that don’t crash. - EVM & Beyond: Ethereum, Polygon, Solana, Tron — if it’s a chain, we’ve probably built on it. - Tokenomics & Token Launches: We don’t just mint tokens; we help them survive the wild. - NFT Platforms: Mint, trade, and scale without ridiculous gas fees ruining the experience. - DAO Structures: Governance setups that users actually participate in. - Wallet Integrations & Crypto Payments: Because if your users can’t pay, what’s the point? 🏆 Why Aegas? We’ve scaled startups from MVPs to $10M+ annual revenue, worked with over 30 clients worldwide, and helped DeFi projects hit major liquidity milestones. We care about your KPIs, not your GitHub stars. Let’s Build. Have a Web3 idea and don’t want to burn months in dev hell? Let’s skip the fluff and talk about your real business goals. I’m just a message away.
