About
I’m Mariana Zavarynska, a software engineer with 4+ years of experience building scalable web applications using TypeScript, Node.js (Express, Nest.js), React, and Next.js. I thrive on turning ideas into robust, user-friendly interfaces and reliable back-end services, with hands-on experience integrating real-time communication tools like Agora, Zoom, and CometChat, as well as Strapi CMS solutions. I’ve worked across SQL and NoSQL databases, Docker and AWS deployments, and CI/CD pipelines, and I’m skilled at delivering clean, testable code with unit, integration, and end-to-end testing.
I’m passionate about building polished interfaces and robust systems, collaborating with cross-functional teams, and exploring AI-driven capabilities with OpenAI to enable innovative features in applications.
