• Developing and maintaining many different systems in different languages – e.g.: Kotlin, Java, JavaScript, Node, Ruby on Rails, Scala and Go.
• CI/CD with Jenkins. Infra as code with Terraform and K8s. Microservices and event communication with Kafka and RabbitMQ.
• Infrastructure using AWS S3, EKS, EC2, Lambda, Kinesis, Aurora, and others.
• Working with React to build internal interfaces used by support teams and scheduling interfaces to end-users. Migration of huge monorepo codebases into different and way more reliable services.

• Dedicated to maintaining the online banking microservices. New features were always added to optimize company revenue or to follow user feedback. Worked more in the Risk Service area where the risk evaluation was automated.
• Node was used in 90% of the microservices.
• Interfaces made with React and Angular. To open banking accountaccounts and also used by internal teams to manage account status and solve customer issues.
• Microservices hosted on Kubernetes and using DataDog. High level of logging and privacy complexity due to banking legislation. Creation of high available deployment system using Jenkins.
• Events used Kafka. Elasticsearch and Hadoop were used for Dashboard generation. MongoDB as database.
• All the application was heavily tested with Unit and E2E tests using Jest.
• Main stack: GoLang, Ruby on Rails, Node/JS, Angular, Python.
• Infra used: AWS S3, EKS, Lambda, Aurora, MongoDB Atlas, Azure Active Directory, Kafka, and ElasticSearch.

• In this role, I’ve developed complex WordPress plugins and/or themes primarily using PHP, Node, JavaScript, Angular, React, and VueJS. Mentored engineers and provide code reviews. Got a great contact with enterprise clients and problems, always developing clever/cheap solutions that just solved the problems.
• Led front-end efforts to implement modern frameworks on complex interfaces with a high level of integration with REST APIs and GraphQL endpoints.
• React, VueJS, and Angular applied to different interfaces like Blog, Dashboards, and CMS to customers like LearnDash, Google, Uber, and Microsoft.
  Serverless Framework and Terraform were used as infra as code solutions. Coordination of all the pipelines from developer experience and deployment process (using Jenkins).
• Infra used: AWS S3, EKS, Lambda, Aurora, MongoDB Atlas, Azure Active Directory, Kafka, and ElasticSearch. All services were deployed using CloudFormation or Terraform.

• Responsible for front-end and a back-end that powers all the search and visual of corporate real estate portals.
• Tested and developed new technologies/features and found new solutions to save money or improve performance/user experience, both front and back end…
• Hosted internal APIs and services at Kubernetes and dockerizing old mono repo that used from C# and Java to Node and Ruby on Rails.
• Deployed using Ansible, CD using Jenkins, monitoring with Grafana, logging, and NoSQL searches using ElasticSearch. PostgreSQL and MongoDB.
• Responsible for implementing Airbnb alike real estate search interface using React and ES6.
• Infra used: AWS S3, EKS, Lambda, Aurora, Azure Active Directory, Kafka, Kibana, and Elastic Search. Also Azure VM instances and Functions.

• Helped developers use the tools, mostly solving the complicated problems they couldn’t solve alone (monitoring, scale, alerts). Improved the support workflow, delivery workflow, and release process (beta, release candidates, tags, test automation, and others).
• Used Jenkins to improve developer experience across the company, implementing Docker and Kubernetes across the company to improve scalability. Managed security of Linux legacy servers, Nginx, Load Balancers, and developing CDN integration due to images’ high demand from customers.

• Developed and personalized dynamic marketing campaigns to big names of the Brazilian retail sector using the Oracle Cloud Marketing platform.
• Used Oracle, PostgreSQL, and to build audiences. Spark to get insights from Data Lake.
• Worked with the creation of an in-house e-mail builder based on React/JS and a couple of microservices that used Keycloak for validation and Kafka to events.
• Java/Spring was used for our backend maintenance – e.g.: Billing, Customer Management, and Prospects (integration with Salesforce).

• Led the remote team to build products based on WordPress (themes and plugins), optimized existing products, implemented new features/fixed bugs, and polished support assistance process.
• Used Scrum to manage the team and track tasks/deliverables, meet OKRs expectations.
• Managed infrastructure with Jenkins, Ansible, AWS, and Travis CI. Building small API services to manage licenses (including payment, suspension, email, and delivery).

Stack: PHP, JS, Python, Ruby on Rails, Jenkins, Ansible, MySQL.
