David Iunevich is a senior software developer with 11 years of hands-on experience building and leading full-stack teams across FinTech, IaaS, and SaaS products. He excels at architecture and refactoring work—most recently raising TypeScript coverage from 10% to 80%, replacing Mongoose with a custom MongoDB ORM, and rebalancing DB models for real workloads. A Toptal-vetted engineer and former technical lead, he combines pragmatic tooling choices (Go, Vue, TypeScript) with strong observability and security practices, including OWASP-driven fixes for SOC 2 readiness. He has a track record of reducing integration time for billing providers, shipping performant marketing sites (100/100 Lighthouse on mobile), and mentoring teams to adopt sustainable engineering standards. Based in Serbia, he pairs entrepreneurial experience as a former co-founder with a preference for solving performance and developer-experience bottlenecks that are easy to overlook.
