Responsibilities & achievements

• Led the consolidation and leadership of the backend team at a retail tech company. • Implemented methodologies and best practices for the software development process, including documentation, pull request policies, and code reviewing. • Established test environments for the QA team and strategies for technical debt mitigation. • Developed strategies for migrating or rewriting parts of the system to microservices, aiming to improve the development culture. • Participated in evaluations of new project viability and collaborated with architects on system design and architecture guidelines. • Implemented CI processes across projects, setting up constraints to enhance code quality through automated tests, static code analyzers, and code format checkers. • Worked with the infrastructure team on the automation of artifact builds, server setups, and application deployments for testing and production environments. • Mentored new team members, addressing technical queries and advocating for high-quality technical solutions. • Diagnosed and resolved performance issues, wrote mission-critical system components under high traffic loads, and coordinated the team to meet challenging business requirements.

Responsibilities & achievements

• As a principal contributor at a prototyping and software development company, I played a key role in transforming the internal buying process for Davivienda, a bank known for its high development and security standards. • Developed the main backend as a JSON API using Laravel PHP, alongside microservices with Node.js on CloudFunctions, integrating with numerous third-party bank services, particularly the bank's ERP system (PeopleSoft). • Built the frontend as a Progressive Web App (PWA) with Angular, enhancing the internal buying process to be more user-friendly, collaborative, and interactive. • Engaged in software requirements negotiation and prioritization with project managers, key users, stakeholders, and maintained close contact with end-users for usability and performance feedback, identifying issues early in staging environments. • Faced challenges with complex business rules, adhering to the user experience designed by the designers for the PWA, and meeting the stringent security requirements needed for each version's release into the production environment. These security checks were conducted by internal bank personnel and an external consultancy hired by the bank. • Often worked independently on building the entire system, managing both the development and coordination of this transformation project.

Responsibilities & achievements

• At a tech services company, I was responsible for developing software solutions for a variety of internal processes, including employee data management, physical access control for employees and visitors, work time tracking, permissions, payroll novelties, employee training sessions, nonconforming products management, and maintenance management for machines and equipment. Additionally, I implemented batch file data synchronization with the ERP system Priority. • These projects were initiated from scratch, where a project manager and I closely worked with company employees to study, normalize, and improve or establish new processes. Once processes were streamlined, we proceeded with software automation. • Without the assistance of dedicated designers, I took on the role of designing the system's look and feel, adhering to guidelines from AdminLTE, a Bootstrap fork framework, for building interfaces. • Managed the setup and configuration of all application infrastructure on OnPremises servers. • The company greatly appreciated the introduction of these solutions, which were implemented using free software, thereby avoiding any third-party license costs.
