Samuel Quintero, web developer in Madrid

I write enterprise software from nine to six. DarosCode is where I apply that to business websites.

How I got here

My name is Samuel Quintero and I work as a software developer at Avanzadi Innovación, in Madrid. DarosCode is not an agency you reach through a form: it is me, and what you hire is what I write.

I started on the design and frontend side and worked my way down from there: first to the browser, then to the server. Two years of training and the rest inside a development company, shipping onto systems that were already in production with people using them every day.

That teaches something you do not learn building one-off sites: what it costs to maintain a decision that was made in a hurry. It is why there are no visual builders or bought templates here, and why every decision on this site has a number behind it.

They are on the list because knowing when to rule a technology out is worth more than knowing how to use it.

What I do not do

Half an hour to find out?

No budget, no long form and no commitment. Half an hour to see whether I fit what you need.
