Hi, I’m Jaissel. Full stack developer with 10+ years in multi-country e-commerce: I connect marketplaces, automate processes with n8n and AI, and make sites easy to find on Google and in AI answers.
{ open to projects }
I work autonomously: I define the problem, build the solution and ship it to production. I also mentor developers and turn business needs into concrete systems.
