I build websitesand online storesthat are easy to use.
I’m Andrés Mesa. I help businesses present their services and products clearly through web development, ecommerce and practical automation.
I do more than write code: I solve business problems with technical and visual judgment.
I’m a web developer and founder of Nexo Web. My background started in backend and software logic before expanding into frontend and user experience. Today I combine both sides to build products that look good and work well.
I work with modern stacks such as Astro, React and Node.js, as well as WordPress and WooCommerce, depending on what the project actually needs. I choose the right solution over the fashionable tool.
I also manage complete delivery processes including hosting, domains, optimization, deployment and automation for digital projects.
