I'm Marina, a software engineer focused on backend systems, developer platforms, and cloud infrastructure. I enjoy turning complex requirements into dependable products that are straightforward to operate.
My day-to-day toolkit includes TypeScript, Node.js, Python, PostgreSQL, Docker, and Google Cloud. I care about readable code, useful tests, observability, and security practices that fit naturally into delivery workflows.
I work closely with product and engineering teams, communicate trade-offs clearly, and help services evolve without losing sight of reliability or the people who maintain them.
