Available to hire
Jazziel Bello. Senior Full Stack Engineer based in Cancún, MX. 8+ years building stuff that actually ships — React, TypeScript, Node.js, Python, AWS. I’ve led platforms at Dell, TechCorp, and Infosys. Love clean architecture, mentoring devs, and turning messy data into dashboards people use. Remote-first believer. When I’m not coding, probably diving or annoying my family with tech talk.
