Work History

As a software engineer, I mainly focus on backend development using technologies such as NodeJs for the API, MySQL and PostgreSQL for the relational databases, and different AWS services as our infrastructure is cloud-based (Cloudformation, EC2, S3, SQS, SNS, RDS, Cloudwatch, Lambda and StepFuncitons).

Moreover, I'm also familiar with frontend technologies in the Angular framework v16, including Typescript, HTML and SCSS with Bootstrap.

Finally, I'm also used to CI-CD good practices, dockerise environments, deploying through Jenkins pipelines created by Jenkinsfile, Kubernetes (K8s) environments with EKS and testing policy and technologies such as mocha, sinonJS, Jest and Karma.
