Led frontend initiatives in microservices architecture and federated modules, coordinating the Angular team under the Scrum methodology. Reduced academic backoffice response times from 30 s to 1.5 s (95%) by eliminating redundant calls with singleton services in NgRx and RxJS, impacting over 500 active users. Automated 8+ mass import flows to zero manual interventions with Angular 18 and reactive state in NgRx, saving 15 weekly hours for the operations team. Reduced post-deploy bugs by 80% by establishing TDD with Jest and Playwright integrated into the CI/CD pipeline, converting critical modules from 0% to 75% coverage and enabling safer releases for 500+ users. Eliminated regressions between teams in production by designing microfrontend architecture with Module Federation, allowing 3+ domains to deploy autonomously without manual coordination. Migrated legacy modules to Angular 16/18 under SOLID principles, reducing technical debt by 60% with guaranteed cross-browser and cross-device compatibility.

Developed and led key technology projects, enhancing user experience and efficiently integrating with AWS infrastructure. Reported to the Technology Manager and coordinated a team of 2 full stack developers. Reduced mass query loading times from 5 min to 4 s (98%) by applying lazy loading and server-side pagination in Angular 17. Increased component reusability by 85% by designing a shared library with TailwindCSS, standardizing interfaces across 3 active projects. Implemented unit testing with Jest from scratch up to 70% coverage and standardized the code review process, reducing regressions and improving the reliability of new integrations. Unified the state architecture of 3 decoupled modules (HR, accounting, and projects) by migrating to NgRx and RxJS, reducing onboarding time for new developers by eliminating implicit dependencies between components.

Led the modernization of critical international retail systems, reporting to the IT Leader and coordinating integrations between offices in Ecuador, Peru, and Colombia. Migrated 2 monolithic sales platforms to microfrontends with Module Federation in Angular 16, enabling independent deployments per domain with zero downtime in 3 countries. Led the modernization of the warehouse system from Angular 12 to Angular 16, reducing processing times from 1 day to 30 minutes (90%). Developed REST APIs to synchronize inventory between international headquarters and local stores, automating stock update and validation flows. Led the responsive development of the internal sales system for Ecuador with Flexbox and CSS Grid, ensuring cross-browser and cross-device compatibility.

Reporting to the Head of Technology Development, led a team of 3 developers to optimize critical systems at UNMSM, improving technological infrastructure and user experience. Reduced critical errors in production by 90% by migrating Angular 12 to Angular 14 and refactoring reactive flows with RxJS under SOLID principles. Improved the rate of addressed complaints from 0% to 80% by implementing accessible responsive interfaces (WCAG 2.1/ARIA) with cross-browser compatibility on web and mobile. Introduced unit testing with Jest in financial system modules, establishing the team's first coverage baseline.

Responsible for collaborating with the product area and leading teams, reporting to the head of the FISI production center. Participated in meetings with clients to define requirements and managed projects using Scrum, integrating BI reports for strategic decisions. Improved the maintainability of 3 critical systems by refactoring legacy code in Angular and PHP under SOLID principles, reducing the average time to resolve bugs. Eliminated manual exports to Excel by integrating BI reports into the Admission system with Angular, reducing administrative query time.
