You need a developer who ships fast, thinks in systems, and doesn't cut corners. I'm an AI-native full-stack engineer with deep experience across Web2, Web3, and DevOps — the kind of developer who can take a product from idea to production without handing off to three different specialists. —————————————————————— HOW I WORK —————————————————————— I use Claude Code, Cursor, and Lovable as core parts of my workflow — not as shortcuts, but as force multipliers. I ship production-grade work in days, not weeks. I move fast, refactor clean, and catch what manual review misses. This means when you hire me for a 4-week project, you often get it in 2 — with tests, documentation, and CI/CD included. —————————————————————— WHAT I BUILD —————————————————————— Full-Stack Web Applications: React / Next.js 14-15 frontends with TypeScript, NestJS or Node.js backends, PostgreSQL / MongoDB databases, REST APIs, authentication, and Vercel / AWS deployment. Web3 & Blockchain: Solidity smart contracts (EVM), DeFi protocols, NFT marketplaces, DAO governance, token launches. Foundry for testing, wagmi and viem for frontend integration. DevOps & Infrastructure: Docker, Kubernetes, GitHub Actions CI/CD, Jenkins, Terraform, AWS (EC2, EKS, S3), Bash scripting, Python automation. —————————————————————— WEB3 PORTFOLIO (all live) —————————————————————— ⚡ Decentralized Lottery — Chainlink VRF v2.5, Automation, 101 Foundry tests, gas-optimized (55% storage reduction) 🚀 Token Launchpad — Bonding curve, factory pattern, slippage protection, fuzz tested 🖼️ NFT Marketplace — ETH/USDC/USDT, EIP-2981 royalties, 7-day timelock, 101 tests 🏛️ CrowdfundingDAO — OZ Governor v5, ERC20Votes, 124 tests + 7 invariants Across these projects I self-audited and fixed 19 logic bugs before deployment — reentrancy paths, prize pool isolation flaws, config manipulation vectors, and emergency withdraw vulnerabilities. I think like an auditor, not just a coder. —————————————————————— STACK —————————————————————— AI: Claude Code · Cursor · Lovable · Anthropic API · MCP Frontend: React · Next.js · TypeScript · React Native · Tailwind CSS Backend: Node.js · NestJS · Express · REST APIs · GraphQL · PostgreSQL · MongoDB · Supabase Web3: Solidity · Foundry · Chainlink · OpenZeppelin · Wagmi · Viem · Ethers.js DevOps: Docker · Kubernetes · GitHub Actions Jenkins · Terraform · AWS · Bash · Python —————————————————————— WORKING WITH ME —————————————————————— → Fast response (0-4 hours) → Daily updates on active projects → Clean, documented, tested code → You own everything I build Send me your project requirements and I'll give you an honest assessment within a few hours.
