As a team leader, I provide feedback, support implementation, and foster teamwork among my backend engineering team.• Through active participation in team discussions, I helped clarify objectives and provided guidance that improved task outcomes by 30%.• In stakeholder meetings, I effectively communicated user stories and details to ensure we understood the company's needs and priorities.• To streamline our development process, I created and implemented a new approach for defining and detailing tasks that reduced our average completion time by more than 20% and increased team confidence in their work.

• I participated in the planning and implementing of a project to track changes in business rules and correctly attach to clients based on activation time, eliminating the risk of updating rules during a client's onboarding process.• I planned and refactored the main application project structure to a modular design, lowering the code coupling and isolating the responsibilities of each module.• I devised and implemented a project to allow for a dynamic onboarding process, where new rules and statuses are create during execution time, based on evaluation of previous business rules.• I implemented the integration with banking systems for automated customer registration and loan requests.• I refactored all integration tests in the application to support parallel runs, significantly speeding up the testing routine. As a result, the overall test suite runtime was reduced by 70%.• I created a system to automate the setup of new onboarding journeys to take only a few seconds, allowing new partners to be production ready in less than 30 minutes instead of weeks.

My responsibilities as a software engineer included planning, designing, and implementing new features as well as maintaining and refactoring legacy systems. • I introduced typescript into the project and helped the team understand and use its advantages, improving the code quality and reducing development time.• I contributed to the automation of mismatch checks in customer data, which blocks the onboarding process, and requests updated data, lowering the cost of re-work and human error by more than 70%.• I implemented websockets for real-time communication between the end client and the server to optimize the onboarding process pushing messages faster while reducing backend load.• I increased the system's reliability by adding a system to assure database atomic operations, avoiding data duplication and partial persistence, and reducing database-related errors to less than 1%.• I collaborated in designing and implementing the migration of the whole application to multitenancy, allowing new partners to create their labels in minutes.

My first professional experience was as a backend developer at Herons Software House where I worked with two main clients.BuildTech• I wrote documentation to reduce the friction new developers had in first contact.• I optimized old features to increase general system performance and stability.• I designed and implemented a system for building classification and filtering.• I also contributed to the application resilience by adding automated tests to cover core functionality.FinTech• I collaborated in planning and implementing an automated security check for customers, reducing the onboarding time in more than 90%.• I implemented a system to build customized messages based on check results, allowing the business to take action faster.• I was also responsible for integrating the new system and ensuring it's security and robustness while performing 10's of thousands checks every day.
