Available to hire
I’m a senior full-stack software engineer with 4+ years of production experience building and owning SaaS and fintech systems end-to-end. I lead backend architecture, system/API design, and production support, with strong delivery discipline using CI/CD on AWS.
I enjoy collaborating in remote, asynchronous environments and building secure, scalable products—whether that’s real-time workflows, event-driven tracking, or privacy-focused applications—using React.js/Next.js, TypeScript, Node.js, and NestJS.
