"I worked with Obed on this project. He was friendly, responsive, and very professional. He helped me install a new circuit and outlet for an EV charger, along with some other light electrical work. His price was fair and competitive with other bids I received, and the work was completed timely and competently. I will reach out to him again for any electrical needs."
