I worked as a Senior Full Stack Developer on the credit card bank team. I developed user stories about requirements, projects and security implementations with the Scrum methodology. For the backend, I programmed with Spring Boot, Node.js, Go and Python, and I used Jira, Sonar, Jenkins, CircleCI, Docker and Amazon Web Services like Lambda, DynamoDB, CloudFront, VPC, EC2, and S3 for the development cycle. For the frontend, I used to work with technologies such as Angular, React, Figma, CastleMock and Postman. Due to my good performance I had the role of technical leader for the development team of Credit Card Cel, this was made up of 4 Senior developers, a Senior QA and a Junior QA .We did a massive continuous integration migration from CircleCI to Jenkins that lasted 1 year, the Infrastructure As Code was created with Terraform for more than 100 components in Amazon web services, and the lambda code was also updated for the correct functioning of the system. This project generated a 40% reduction in cloud costs and process optimization that allowed changes to be deployed 30% faster, in addition to meeting the bank's technology and security guidelines. We also developed a project to purchase credit card portfolios from other banks, Which allowed the marketing teams to increase the average onboarding by 10%. In addition, we executed a project to acquire credit cards with first purchase in allied businesses, thus increasing placement in new market niches. I was also in charge of design and develop security improvements such as point-to-point encryption systems between components and personal data encryption in order to meet the necessary security criteria to protect the system from any attack and comply with legal regulations.

I initially joined as a full stack developer and after nine months, I assumed the role of leader for the billing and support team in the Development area at the national level. I worked with user stories with Scrum and I programmed with Spring Boot, Python, React, Angular, Node.js, PostgreSQL, Git, Jenkins and Amazon Web Services such as Lambda, DynamoDB, SQS, CloudWatch, EC2, and S3.I was responsible for the analysis, design, and implementation of requirements for various projects. My role included project management and development, particularly in the migration of the SimCard activation system, which involved assisting sellers nationwide to resolve system crashes that hindered the onboarding of new clients, converting stability from 60% to 99%. Additionally, I led the migration of the electronic billing system, enhancing stability and enabling more precise financial closings for the accounting team. This reduced the monthly closing discrepancy from 19% to 2% and allowed the closures to be prepared in a single day instead of a week.

I developed software requirements and projects using Java, Selenium, PHP, Angular and PostgreSQL. I carried out the development and implementation of customized software and had the responsibility of speaking and training the company's employees who used the platform to manage their sales and accounting.I faced the challenge of transforming the web platform into a fast, lightweight, and intuitive hybrid mobile application using Ionic with REST services. The app was successfully launched on both the App Store and Google Play.
