K. S. H. — software developer, web applications, databases and integrations

TypeScript React JavaScript PostgreSQL Supabase NestJS


About Me

Hi, I'm Kay — a software developer building responsive web interfaces, internal tools, and applications for real users.

My frontend work includes React, TypeScript, JavaScript, HTML, CSS, and accessibility. I also work with PostgreSQL, authentication, APIs, and third-party integrations.

I've built and maintained production software for a business, contributed to collaborative applications, reviewed pull requests, and published themes used by the Obsidian community. My background in organizational leadership and client-facing work shapes how I approach development: understand the problem, communicate clearly, and build for the people who will use the software.

I'm seeking a software development role with a focus on frontend engineering and user interfaces.

The system combines PostgreSQL Row Level Security, server-side functions, and integrations with Google Calendar, Stripe, and Resend.

Open-Source Obsidian Themes

I design, publish, and maintain themes distributed through Obsidian's community ecosystem.

Leadership & Community

I founded Syntax Studio, a programming community for collaborative learning, project building, technical troubleshooting, and peer support.

My team experience includes breaking larger features into actionable issues, reviewing contributions, helping contributors resolve implementation problems, and keeping project scope aligned with delivery requirements.
