✔ 6+ Years in Blockchain Development & Architecture ✔ $100K+ Earned on Upwork ✔ 500+ Audit-Ready Smart Contracts Delivered ✔ DApps, NFT Marketplaces & Token Launchpads Successfully Launched I am Ahsan Ilyas — a full-stack blockchain developer and smart-contract architect with 6+ years of experience on Ethereum, Polygon, BSC, and Solana (Rust/Anchor). I design token logic, write audit-ready contracts, and deliver stable Node.js/TypeScript backends and React/Next.js frontends. Services I offer: ✔ Smart contracts (Solidity / Rust-Anchor, Move) ERC-20/721/1155, custom logic (roles, fees/tax, pausable/upgradeable), staking/vesting, factory patterns, bonding curves. ✔Presales & launchpads: tier/cap logic, claim portals, liquidity setup, listing handover (incl. memecoin/fair-launch flows). ✔DeFi / DEX integrations: AMMs/perps, referral/fee rails, PnL, real-time order/position sync. ✔NFT platforms: minting engines, royalties, metadata/IPFS pipelines, collection dashboards/marketplace basics. ✔Cross-chain & bridges: LayerZero/Wormhole/Axelar (lock/mint, burn/mint, OFT), relayers/watchers, route-fee accounting. ✔Smart contract audits, fixes & hardening: security reviews, remediation of third-party findings, gas optimization, coverage-driven tests (Foundry/Hardhat). ✔Web3 backends & APIs::event listeners, webhooks, queues (BullMQ), idempotency & reorg handling, monitoring, and CI/CD. ✔Frontends: React/Next.js admin panels and dashboards, wallet flows (wagmi, WalletConnect, Web3Modal). ✔Blockchain × AI solutions: on-chain agents/workflows, risk/fraud analytics, LLM-assisted ops, data pipelines. ✔Tokenization / RWA: ERC-3643/1400-style permissioned tokens, whitelist/oracle flows, pro-rata USDC distributions, compliance-friendly design. Why do clients work with me? End-to-end ownership: clear scope → tested code → mainnet deployment → documented handover. Security-first delivery: audit-ready tests, safe upgrade patterns, key/role hygiene. Direct communication: scoped milestones, transparent trade-offs, predictable timelines. My tech proficiency: ✔ Stack: Solidity • Rust/Anchor • Foundry/Hardhat • ethers.js/viem • wagmi/WalletConnect/Web3Modal ✔ Backend: Node.js (Truffle & Hardhat for testing, APIs for NFT metadata generation, IPFS storage, avatar generation) ✔ Frontend: React (components, Redux, Web3, wallet integration) & Next.js I consistently deliver high-quality work, meet deadlines, and prioritize long-term client relationships.
