My contributions spanned multiple areas, always focus on enhancing the robustness and efficiency of our infrastructure:Chaos Engineering: Designed and improved our internal Chaos Engineering scenarios based on LitmusChaos. Resulting in a 30% increase in the number of running tests, significantly enhancing the resilience of our underlying infrastructure.Observability: Improved our observability capabilities by adding new monitoring cases and optimizing existing dashboards. This led to more actionable insights and faster issue resolution times.CI Pipeline Optimization: Revamped existing Continuous Integration pipelines to improve performance and ease of use. By introducing new templates and simplifying complex workflows, which increased overall efficiency and reduced errors.Terraform Code Migration: Aided in the migration and improvement of legacy Terraform code. I implemented remote backend configurations that solved common problems like race conditions between different runs.

As part of the cloud infrastructure team lead a small team of internal and external developers to delivered high available cloud environments on Amazon Web Services, for our clients, automating the process of spinning up new environments and reducing creation time by 25% from previous solutions, using technologies like Terraform and EKS.Among other task coordinated and lead production releases across different teams and clients.Helped to maintain and optimize our set of infrastructure components running on Google Cloud Platform based on Terraform and GKE, which allowed us to increase retention of our users on the platform by 23%Most of our IoC lacked of tests, so we researched, designed and implemented an automated testing solution for our infrastructure, using tools and languages like Terratest, Localstack, Jenkins and GoLang increasing our coverage on 70%On a parallel on-going effort manage to contribute to different community Terraform providers to incorporate new features and help the community take advantage of our internal effort.

As part of the infrastructure team, I was responsible for planning and implementing a high available monitoring system that observe all our Kubernetes clusters, using technologies such as the Prometheus Operator, Alertmanager, Grafana, Thanos, Loki and Jsonnet.Built a Prometheus Exporter for our AWS Reserved Instances using Golang that helped us to control, alert and reduce in 45% our AWS monthly bill by adjusting reserved instance utilization according to our real needs.Helped to containerizing all our applications in order to improve our delivery pipeline to make it more progressive, by reducing releasing times in 35% using technologies like Kubernetes, Kustomize, Istio, Spinnaker and Concourse CI.As well as giving support to all the different teams to cover their needs, maintaining our internal set of tools and improving the different pipelines and workflows to help us continuously deliver software of quality where security it is essential.

As the main Infrastructure Engineer, I was responsible for architecting, building and maintaining our customers infrastructure, using different set of automation tools and services, from configuration management (Ansible) and orchestration tools (Terraform) to different providers like Amazon Web Services and Microsoft Azure.Planning, building, maintaining and monitoring a highly available and scalable system using different set of tools from container management (Rancher/Cattle/Docker) to service mesh (Linkerd).As well as of providing the development team with the needed tools to accomplish continue integration/development and observability, from Monitoring (Datadog/Statd/Telegraf), Logging (Graylog/Fluentd/Elasticsearch) to CD/CI (Jenkins) and Docker authentication and image management (Portus).

As part of the platform team, I was responsible of building and maintaining our product in its two phases: as a monolithic app and as a distributed set of (micro)services, using different technologies from PHP and Laravel to Lua, Nginx, Go, NodeJS, Scylla, Elasticsearch, Redis, RabbitMQ and PostgreSQL.

As the main Software Engineer at Contaczilla, a contact manager system written in a legacy technology (Zend Framework 1), my responsibilities were fixing customer issues and integrating new small features whilst refactoring the old code and creating a side project using a new approach, a distributed system build with Laravel and Symfony.

Worked as a Freelance at Fanatic Design in different projects, developing mainly in PHP using different frameworks as Concrete5 and Yii as well as consulting about infrastructure and technology as a Systems Analyst.

I was responsible of integrate different carriers (DHL, myHermes, Parcelforce) and payment platforms (Paypal, Authorize.net) through their APIs into our shipping platform, worked with technologies like PHP, MySQL, Python, Flask.

Worked as a Research and Development Engineer researching about new technologies and developing applications in different projects.Worked with Phonegap/Cordova, Javascript (Backbone), CSS, HTML5, Liferay (Portlets) and Grails (Groovy on Rails) developing projects to Companies as Fagor, Inditex, Alimerka and more.

Personal Project (Sign Language Interpreter) presented as my final Project at the University. It was an application to translate sign language. I used an open source C# Framework called Touchless to detect the hands movements.

At this position I worked in a team writing the technical papers and organizing the communication between Infobotica Research Group and other Companies to prepare calls together to European Union projects (AVANZA, 7PM, SUDOE, INNPACTO). Communicating in an international environment.

During this internship I was the responsible for managing and maintaining the Citrix infrastructure of the Economics Faculty at the University of Oviedo.

At this software company I was converting projects from Visual Basic to C#. Later, I started to work with the main team developing projects with C# strengthening my knowledge in C#.

I was responsible of the maintenance and management of the technical infrastructure (servers, computer etc). Helping design logos, business cards, photo restoration, photo repair and retouching using Adobe Photoshop, Illustrator and Freehand.
