I am Jesus Guerrero, and I am here to support small businesses and nonprofits who are looking for support or consultancy around their IT and Tech. I have worked with different non-profits who don't have the budget to have a dedicated IT department or even an individual. As the world has transitioned to work from home and/or a hybrid model, and IT Support or Tech Support person is needed. I am here to help with anything (within my capacity) around IT and Tech. Need to setup Google Workspace, have data entry tasks, need dashboard created, want to know what the best practice for tech is, feel free to reach out to me. Remember, it doesn't hurt to ask.
