I worked on the first B2B solution at Qconcursos (now GrupoQ) customized for YDUQS. This multi-tenant white-label application integrated with the client's academic platform, enabling students to practice subjects with applied questions and take exams. Within the first 6 months, the application delivered over 1 million exercises and reached over 700,000 college students within the YDUQS holding. Moreover, the system facilitated the import and registration of questions, offering valuable insights into the quantity and quality of questions across different modules.Currently, I am part of a team dedicated to enhancing the student experience through a customizable platform that offers courses and graduate programs from our partners. This platform operates as a B2B2C solution and serves over 500,000 active users.My daily activities includes:- Creating, designing, and implementing processes to assist in the team's day-to-day operations.- Collaborating with product manager and product owner to define features, assess technical feasibility, milestones, and deliveries. Additionally, I provide feedback and inputs in design reviews, to ensure designs meet functional, usability, and aesthetic requirements.- Leading SCRUM ceremonies.- Refining features, planning, and providing technical descriptions for both back-end and front-end development tasks.- Conducting code reviews, mentoring team members, and facilitating team performance.- Architecting, modeling, and developing end-to-end features, both backend and frontend.Design Patterns and Best Practices: Use Cases, Services, Factories, Policies, Queries, Serializer, SOLID, KISS, DRY, Clean Code, DDD, Rubocop.Technologies: Ruby on Rails (API), React.js, Refine, RSpec, TDD, Sidekiq, Postgres, MySQL, Metabase, NewRelic, Rollbar, Docker, Docker Compose, Git and Linux.
