I'm Alejandro Macedo Paredes, a full stack developer in Peru. I'm driven by solving problems with technology and learning something new every day.

I combine good practices, performance and clean design. I enjoy teamwork, documenting what I build and delivering solutions that people can actually use.

Today I mostly work with NestJS and PostgreSQL, and I've built systems for barbershops, grocery stores, veterinary and dental clinics, real estate and e-commerce.
