Hello, my name is
Ionwyn Sean.
Think up. Build down.
I am a full stack software engineer currently working at the BC Government. I specialize in architecting and engineering web applications, while building and maintaining the platform infrastructure that supports their deployment and performance. I also enjoy producing music, playing piano and guitar, football, and exploring new technologies to enhance my skills.
About Me
My journey as a software engineer began in 2000 when my uncle introduced me to coding. This early passion led me to work with notable organizations like HP Teradici, and PressReader, where I developed my skills in creating robust and efficient software solutions. I also embraced the challenge of being self-employed, delivering high-quality projects for various clients.
Currently, as a full stack software engineer at the BC Government, I specialize in engineering both the design and functionality of web and desktop applications. My primary focus is on building highly performant, data-driven solutions, ensuring cohesive and efficient digital experiences.
Here are a few technologies I’ve been working with recently:
- JavaScript (ES6+)
- C#
- React
- .NET
- Node.js
- OpenShift
- NextJS
- MS SQL
