Moneris, API Architect

I am an API-first advocate and have been a tech enthusiast since I laid my eyes on those Pentium I processors. I have been in the profession for the last 12 years. While I am currently architecting APIs at Moneris, I have worked in the software industry across the globe. I was a software developer in Italy and Tunisia and a technical lead and architect in Saudi Arabia, and I ended up in Canada, where I worked as a senior software engineer and tech lead for several companies. Outside work, you can always challenge me to a fun chess duel or get me chatting about APIs and technology over a cup of coffee!

Ninety-three percent of API teams still face collaboration blockers. The 2025 State of the API report reveals how you can unlock the productivity gains that API-first promises, but scattered tooling prevents.
