About

Full-stack developer with 2+ years of experience building modern web applications using TypeScript, React, Next.js, Node.js/Express, MongoDB, and Docker. I enjoy turning ideas into polished products — from first design in Figma to cloud deployment on AWS. I previously worked in education and hold a Master’s degree in Comparative Literature. That background strengthens my communication, UX thinking, and ability to understand user needs — especially in learning-focused products. My latest project, Linguardian, is a language-learning platform I designed, developed, and deployed using a CI/CD pipeline on AWS (EC2, ECR, S3, CloudFront). It includes user authentication, spaced repetition learning, and a community-curated dictionary. I’m currently looking for full-stack development roles where I can contribute to purposeful products, ideally in EdTech — but I’m open to any role where I can grow and build great things.
