What I'm looking for

I’m looking to build sustainable, long-term products—designing scalable backend services and user-focused React experiences. I want a collaborative team that values engineering fundamentals, strong CI/CD on AWS, and responsible AI tooling for quality.

I am a passionate software engineer with 8 years of experience in full-stack development, specializing in Java, Node.js, and React. I focus on designing scalable architectures, implementing robust backend services, and creating intuitive, responsive user interfaces that improve user engagement.

At McKinsey & Company, I spearheaded scalable Java and Node.js backend services for high-traffic educational applications, and I architected a React + TypeScript frontend that enhanced accessibility and user experience. I also optimized CI/CD pipelines and containerized AWS deployments, reducing deployment times by 30%, and strengthened observability and operational robustness using New Relic and Grafana.
