We first hired Sonia to create our business webpage (solucionesdelavado.com). After that, we rehire her to help us create a CRM and some additonal functionalities for our ERP.

The results were great. She does not only provided a good code but also easily understood our business needs and was able to provide the solutions we needed.

Always a pleasure to work with Sonia
