Frontend
Responsive, accessible interfaces for dashboards and self-service tools.
Hi, my name is
Jason Tiet.
I build things for the web, end to end.
I'm a full-stack software engineer in San Francisco who builds customer-facing products, internal tools, and developer workflows, moving between frontend and backend depending on what the project needs.
01. About Me
I'm a full-stack software engineer with experience building customer-facing products, internal tools, and developer workflows. I've worked across React, Vue, Node.js, Express, Java, and cloud infrastructure, and I'm comfortable moving between frontend and backend work depending on what the project needs.
I enjoy solving practical problems that make products easier to use, systems easier to maintain, and teams more effective. I'm at my best when I can take ownership of a project, collaborate with different teams, and turn an unclear problem into a straightforward, reliable solution.
02. Skills
