I’m Haekal Mimtazulfaqhi Zaydan, a Full-Stack Engineer who builds reliable production systems across AI pipelines and Web3. I work daily with Node.js, Python, and Solidity to design end-to-end solutions—from automated data collection and multimodal AI processing to blockchain-based tracking and secure APIs. I’m especially focused on quality: I audit model outputs for logical accuracy, alignment, and duplication, so users get high-fidelity results. Recently I’ve developed an always-on crypto AI scraper pipeline with vision-based classification and duplicate detection, and I also delivered decentralized supply-chain traceability using Solidity smart contracts and an end-to-end backend flow.…I’m Haekal Mimtazulfaqhi Zaydan, a Full-Stack Engineer who builds reliable production systems across AI pipelines and Web3.
