Steve Tan

I am a dedicated software engineer with 9 years of experience specializing in web and mobile applications. I excel in full-stack development, combining backend expertise in Java and Node.js with frontend skills in React and TypeScript. I’m passionate about building scalable, maintainable systems that deliver meaningful societal impact, leveraging AI tools to accelerate development while maintaining strong engineering judgment.

At Capgemini, I led the design and implementation of scalable backend services using Java and Node.js, improving system reliability and reducing downtime by 30%. I architected and developed a modern React + TypeScript frontend, enhancing user experience and decreasing load times by 25%, and I owned CI/CD pipelines in AWS to automate deployments and reduce release times by 40%. I also implemented observability solutions with monitoring and logging to proactively identify and resolve operational issues.

I bring a long-term architecture mindset and a culture of operational excellence—collaborating with cross-functional teams to define system boundaries, leading code reviews, and mentoring junior developers. I integrated AI tools into development workflows to accelerate feature delivery while validating code quality, security, and performance, and I helped drive incremental upgrades with minimal disruption. Earlier at Civica Pte, I developed RESTful APIs, built reusable React components with TypeScript, improved performance, and supported test automation and migration efforts from legacy PHP to modern JavaScript and Node.js stacks.
