About Nelly

I am a full-stack web developer specializing in creating modern, fast, and business-oriented platforms.

I work with technologies like SvelteKit, Supabase, and Stripe, developing complete solutions from scratch: frontend, backend, and integrations. I have experience with ticketing platforms, reservation systems, and projects connected to external APIs, particularly in the travel and events sector.

My approach goes beyond technical development: I build products designed to convert, with a good user experience, performance, and scalability. I get involved in every project, analyzing what the business truly needs and proposing clear and effective solutions.

I work in a structured, step-by-step manner, ensuring quality at every stage of the project.
