zackness is the public name of Frank Alejandro Castillo: software developer, Mechatronics Engineering student at UNEXPO, and musician.

He designed and built AprendePIC18 as a web platform (Astro, TypeScript, bilingual content) to navigate the Microcontrollers course with a study path, interactive exams, and lab tutorials — not to replace official course material, but to organize it.

Interactive tutorials (step-by-step guides and UNEXPO labs) are not a separate section: they are interleaved on the study path after the theory that prepares you. The tutorial catalog helps you find a specific lab; the recommended order is always the path.

Progress (path + guides + labs + exams) is saved in the browser and, with a CALETAS account, syncs to the cloud.

His portfolio includes other educational and software projects such as CALETAS, Franky+, and apps for the university community. See more at zackness.pages.dev.

StartupVen is the company that maintains and operates AprendePIC18 within the CALETAS ecosystem: site updates, service reliability, integration with the CALETAS platform (user accounts and progress), and technical support for the resource.

Its focus is shipping educational and technology products with quality and continuity, so students and instructors can use the tool without worrying about infrastructure.

Content is based on lectures, lab practices, and evaluation material from the Microcontrollers course in Mechatronics Engineering at UNEXPO, complemented with the PIC18F4550 datasheet and PIC18 instruction set.
