As part of the global initiative to turn a Moleculer framework into a polyglot solution, I've begun helping in Moleculer Go, a complete rewrite of MoleculerJS in Golang. Together with the rewrites in Python, Clojure, and Elixir, we expect to better support startups and enthusiasts looking for a seamless integration between their applications written in two or more of those languages, since each implementation can communicate and operate with each other.

I am currently a member of the team releasing the CentOS version of Origin Kubernetes Distribution (OKD), the free upstream version of the OpenShift Container Platform.

I presented a demonstration and coding session on how to develop APIs using Golang and Goa.design framework. The final work is saved on a git repository, containing slides, a walkthrough, and a couple of challenges. I made this presentation for the Wellington Golang User group. More details about the presentation in the link below.

I wrote an article showcasing Goa and how we can effectively develop APIs using its framework, including essential features such as authentication and authorization from its inception. The article is currently published on the Toptal Blog.

This is a simple example of a Terraform module I developed for obtaining AWS ACM wildcard certificates automatically for domains users manage on Amazon Route 53.

I helped to implement performance benchmarking over OpenShift/Kubernetes using tools like Splunk, ELK, Grafana, and Prometheus.
We set up Prometheus to collect metrics out of the cluster and developed key applications, and feed to Splunk and Grafana, where dashboards were developed to visualize such information. The dashboards ranged from containing simple information—such as latency or transactions per second—to more complex constructs—such as logged users before nodes failed or sessions left in hanging state.

I helped to develop the components required for Furnace to support Azure and GCP serverless architecture.
Furnace is a big data project where data scientists can rely on well-defined building blocks for constructing data pipelines with no need to manage the infrastructure.

I presented a paper on DevOps and Experimentation on Large IT Service companies. More details about the talk can be found in the link below.

I presented a paper on Packaging OpenShift Origin Kubernetes Distribution (OKD). More details about the talk can be found in the link below.

I presented a paper on Kubernetes Operators: what they are currently used for and how to develop one to manage applications using either Golang or Ansible. More details on the paper can be found in the link below.

I helped chief economist Erik Stettler write an article describing the DevOps and cybersecurity challenges healthcare companies face and how open talents can help them overcome. That article also led to a presentation we did to CIOs during the pandemic, explaining the net value companies can take from engaging open talent worldwide to overcome skills shortage and tip the scale towards enhanced security and collaboration in a remote-working setting.
