About

Hi there! I’m Jinghuan Wang, a passionate full stack developer focused on building cloud-native web applications on AWS. I design, build, and deploy scalable solutions using React, Next.js, Node.js, and TypeScript, with a strong emphasis on CI/CD, infrastructure as code, and AI integration. I hold a PhD in Molecular Biology, which fuels my critical thinking, analytical skills, and a scientific approach to problem solving.

I’m a Finnish citizen eligible to work in the EU. I enjoy collaborating on challenging projects and bringing rigorous engineering practices to life in fast-paced environments.

Projects · 1

A showcase project demonstrating my end‑to‑end full stack development skills — covering architecture design, UI design, and both backend and frontend implementation, through to cloud deployment. Built with Next.js, React, Node.js (Express), and TypeScript in a PNPM monorepo, it leverages AWS Lambda, API Gateway, DynamoDB, S3, and AWS Comprehend for a fully serverless architecture and AI‑powered mood analysis. I also implemented a responsive frontend interface, optimized for both desktop and mobile.

Both the frontend and backend are deployed on AWS Lambda, with automated CI/CD pipelines managed through GitHub Actions and AWS CodePipeline for seamless delivery and scalability.
