Starting in 2011, I been working with a range of RESTful APIs from small micro-services to big core APIs. I've worked successfully with several methodologies, including quarterly planning in a big core back-end team and weekly sprints in a cross-functional team.

The projects were always very minimal concerning technology to get as much performance out of the hardware as possible. For example, we didn't have an ORM, used small frameworks, fine-tuned the cache-control directives (for a Varnish cache), split the queries to different shards for different QoS, among others.

I also have experience writing batch programs to process significant amounts of data, handling database migrations, web scraping/crawling, binary log file processing, and more. For smaller scripts, I tend to use Python, but for heavy-duty multithread processing, I prefer to use Java.

Starting with small fixes in a Go client in 2016, I then built my website using Go and instantly fell in love with the language.

While I've enjoyed working in mission-critical core teams in big companies, nowadays, I prefer working closely with the product owners in smaller groups and proposing solutions and even new features.

I'm currently working with Go for back-end microservices along with daemon agents that we install on client machines. It was a full-stack position, so while I specialize in the back end, from time to time, I also did simple front end work. This work mostly consisted of back-office admin tools, email templates for CRM and transactional emails, business reports, and whatever was necessary to supplement a robust back-end product.

I fully developed the site, Mininoticias.com.ar, that shows a small snippet of all the news from the major online newspapers in Argentina.

It uses Java for web crawling and indexing in Solr, and Go for the web framework (back end and front end). The website is running in the cloud and getting about 5,000 visitors per day.
