Background

About Jack Mao

Software engineer with 4+ years of experience designing and building scalable systems across the full stack using Typescript, React, and C#.NET. Ability to lead cross-team initiatives, deliver impactful features, and mentor junior developers. Passionate about building high-quality, customer-focused software in a collaborative, agile environment. Currently, I work in a team that maintains and develops new features relating to the core Invoicing product, focusing on backend applications using C#.NET Framework and.NET Core, and developing APIs to support various applications. I occasionally develop front-end applications using TypeScript + React, integrating them with backend API's and services. All of our services are hosted on the cloud using AWS, and Kubernetes. I am also proficient in optimizing database operations with Microsoft SQL Server, writing efficient SQL queries and stored procedures. My strengths lie in my broad technical expertise as a full-stack engineer, spanning multiple Xero products from newer innovations to legacy systems. I have a knack for quickly understanding and contributing to existing setups, and I excel in collaborating across teams. Throughout my time at Xero, I've enjoyed mentoring junior engineers and fostering a collaborative work environment.
