It's been great working with Nicolas. He was very quick at understanding what I was trying to build and he built it within the timeline provided and at the cost we agreed on. Probably the best part is how easy it is to get in touch with him and agree on changes to be made as the product is developed. Highly recommend him.

We hired Nicolas to optimize and add automation to several of our Google Sheets, and he exceeded expectations. He quickly understood the scope of our needs, offered smart workflow improvements, and implemented clean, effective automation that saved us hours of manual work. Communication was clear and timely throughout the project, and he was flexible with revisions. Highly recommend for any Google Sheets or automation tasks!

It's been a great experience working with Oscar all the way through. He's been very precise from the very beginning with regards to pricing, timelines and the ease of communication was the best I've experienced. He was always available to talk on short notice regarding the changes to the project. He is very knowledgeable in APIs and backend but most importantly he was very helpful in building a streamlined architecture.
