ABOUT ME
AI Researcher and Sr. Software Engineer
AI Researcher and Sr. Software Engineer
I have been a web developer since 1997, over 25 years! I work in JavaScript, TypeScript, Ruby, and Solidity, and I like to use NextJS, TailwindCSS; and while I spent years and years in SQL, I find MongoDB a lot more efficient for web apps.
Take advantage of this incredible opportunity to learn from an industry expert with years of experience in both programming and AI. With expert guidance, you'll gain the knowledge, skills, and confidence you need to excel in the world of prompt engineering and AI-powered programming.
Book me here @ Codementor 5 days a week! (North American timezones)

I have been coding in JavaScript since 1997. I have seen all the technology come and go and change. I can also write TypeScript. My expertise (that you wont find elsewhere) is functional JavaScript you can actually read!

My god... 20 years. I was playing Warcraft and throwing down <blink> tags from a cyber-cafe.......
When I am not coding my primary language, it is usually because I am writing HTML/CSS.

Postgres is my favorite ACID compliant RDBMS. I have been using SQL for many, many years now, and I still prefer relational data to schemaless databases. I LOVE MONGODB (but the two do different jobs)
