What I'm looking for

I seek a collaborative, product-focused team role where I can build scalable web applications, contribute to architecture, and grow into technical leadership.

I am a senior full-stack developer with eight years of experience building scalable web applications using React/Next.js, Vue, Node.js, and TypeScript. I focus on creating responsive, modular interfaces and robust backend services deployed in containerized, production environments.

My work includes building real-time chat interfaces, integrating Markdown and LaTeX rendering, implementing authentication with third-party providers, and managing billing/subscription systems. I have deployed services using Docker, Nginx, and Azure virtual machines while ensuring data sovereignty and compliance.

I collaborate in agile teams, use tools like Notion and Jira for documentation and tracking, and prioritize accessibility, maintainable styling, and performant database querying to deliver reliable user experiences.
