Antonio Ivanovski

I’m looking for a senior full-stack or product engineering role where I can build and operate meaningful web products, developer tools, or SDKs. I do my best work in small, remote teams where I can contribute across architecture, hands-on implementation, integrations, deployment, and product decisions. I'm a senior software engineer with 10 years of experience building web applications, SDKs, and security-sensitive products. I work across frontend and backend, primarily with TypeScript, React, Node.js, PostgreSQL, and Docker. I enjoy owning products from architecture and implementation through deployment and ongoing operation. At Vidos, I established the React and Node.js monorepo and built the main client application for a digital identity platform. This included a composable credential-verification architecture and client-specific prototypes. At Mailchain, I was the primary developer of an end-to-end encrypted React mail client and helped turn its core functionality into a JavaScript SDK for account registration, recovery, and encrypted messaging. Earlier, I built collaborative document-editor features at H4 and led a four-person team that delivered and certified an Android 3-D Secure SDK at Netcetera. I now maintain Spliit Cloud, an open-source expense-sharing service with approximately 300 registered users and 20,000 expenses. I've added secure authentication, imports from Spliit and Splitwise, exact split calculations, durable background jobs, and AI-assisted expense entry from receipts and voice input with human review. I'm interested in senior full-stack and product engineering roles where I can combine hands-on development, sound architecture, developer integrations, and end-to-end ownership.
