Software Engineer



I'm a Control and Automation engineer passionate about software development. I started my career in 2012 programming for PLC (Programmable Logic Controller). Also, I worked developing SCADA (Supervisory Control And Data Acquisition) systems and some desktop applications using C#. In 2015, I started to learn about Web development with Java, and then in 2016, I started my journey with Web development (using Python/Django) as a freelancer. In 2017 I got my first full-time employee job also working with Python and Django and I've been working with it ever since. Currently, I'm working at Oowlish for Petco (a huge pet company from the US) where I already worked on a set of products. In addition, I've been working with cloud computing services (basically AWS), infra as code tool (Terraform), monitoring tools (APM, Log Analytics, Error Tracking), and also I've been taking care of applications in production.

    In addition to software development, I led a team during the development of a new product for one of our clients (for around 8 months) and also I'm still helping other teams to improve their products (reliability, scalability, performance) in order to deliver the best for our clients.

    Software Engineer


    At Oowlish I’ve been working mostly for Petco (a huge pet company from the US). There, I've been working on products that impact thousands of people every day. Our main tech stack is Python, Django, Django REST Framework, Graphene (GraphQL framework), and PostgreSQL as a relational database, but not limited to that. Also, I'm involved in the applications' infrastructure management and operations. We automate processes as much as possible using IaC tools such as Terraform and CI/CD tools such as Gitlab CI, and Jenkins. Also, we run our workloads on AWS (Lambda, ECS, RDS, Elasticache, Elasticsearch, KMS, DynamoDB, S3, API Gateway, CloudFront). In addition, we understand how important is to monitor our applications and we're using services such as AWS CloudWatch, New Relic, Sentry, SumoLogic, and PagerDuty to keep eyes on our applications' health.
