I am a backend-focused software engineer with over six years of experience. I design and maintain scalable backend services and APIs, specializing in microservices, event-driven architectures, and secure data flows. I work with TypeScript/Node.js, Python, and Rust, and I have hands-on experience with databases, containerization, CI/CD, and cloud infrastructure. I thrive in domains like fintech and high-reliability systems, bring an analytical mindset and technical rigor, and value autonomy and rapid domain understanding. I enjoy turning complex requirements into robust, production-grade solutions and collaborating across cross-functional teams.
