Hi, I am Toby.

I am a software developer who loves to learn and teach. Currently my interests are compilers, programming languages, software architecture, assembly language programming, and debugging. I have listed below links to instruction videos and essays I've made on these topics and more. I hope you find them useful or enjoyable.

I offer mentoring services for helping developers level up.
