Bio

As Technical Lead, I spearheaded the migration of the Bancanet platform from Angular version 10 to 17, significantly enhancing development efficiency and product quality by leveraging new features and performance improvements of Angular 17. Key achievements include a 30% improvement in build and deployment times, a 25% increase in the rate of introducing new features, and a robust documentation framework that reduced the learning curve for new team members and improved overall project knowledge management.

Developed a Server Log Dashboard Management MVP for Arca Continental with Angular, Node.js, and SQL, providing real-time server status visuals. At Research Solutions, I designed web apps for scientists using Angular, Node.js, Python, GCP, and Firebase, streamlining scientific workflows and crafting essential tools like the COVID-19 Research Viewer Gadget during the pandemic's peak.

Future Aspirations & Unique Offerings:

Eager to tackle challenges requiring cutting-edge solutions and creativity in my next role. As a certified yoga instructor, I bring balance and unique problem-solving methods to my teams.

EXPERIENCE

Citibanamex, Software Lead Engineer

Dec, 2023 - Actual • Hibrid

  • Before the migration, the Bancanet platform operated on Angular version 10, limiting our development team's access to the latest features and resulting in reduced performance and efficiency. As the Technical Lead, I spearheaded the transition to Angular version 17, a move aimed at not just updating the framework but fully capitalizing on its new features and performance enhancements to boost development efficiency and elevate product quality. This comprehensive effort involved a detailed analysis to weigh the benefits and anticipate any challenges of the upgrade, leading the migration strategy with minimal impact on ongoing projects, and fostering team adaptation to Angular 17's advancements like better type checking, quicker build times, and more effective change detection methods. I also established a thorough documentation protocol to detail the migration process, key learnings, and tips for maximizing the use of Angular 17.
  • This migration yielded significant improvements: build and deployment times were reduced by 30%, and the development team was able to roll out new features and fixes 25% faster, enhancing our workflow. Moreover, the transition to Angular 17 facilitated a smoother, more collaborative working environment, evidenced by a 50% decrease in merge conflicts and development bottlenecks. We also developed a comprehensive documentation system, which has greatly diminished the learning curve for newcomers and fortified our project knowledge management, ensuring that the Bancanet platform's upgrade has not only optimized our current operations but also laid a solid foundation for future enhancements and innovations.
