About Miguel

How can I support your team?

I bring over 7 years of experience turning complex ideas into robust, scalable, and high‑performance applications. My approach goes beyond writing code; I focus on optimising development efficiency, reducing delivery times by more than 70% through package modularisation and the integration of solid architectures.

If the codebase is difficult to maintain, I can refactor it to improve efficiency for both the app and the team. At Plenitas, I created a migration plan to minimise development impact, successfully applying refactoring to menus and services.

My added value: Quality and Mentorship

What sets me apart is my commitment to technical excellence and team growth. I don’t just implement solutions, I design structures based on Clean Architecture and SOLID principles that ensure long‑term maintainability. I also have experience mentoring other developers and establishing agile methodologies (SCRUM) to keep workflows smooth and consistent.

Projects

Throughout my career in sectors such as healthcare, education, and entertainment, I have successfully managed:
  • Multiplatform Apps: End‑to‑end development with Flutter for Android, Android TV, iOS, Web, and desktop environments.
  • Streaming Systems: Maintenance and optimisation of interactive platforms for Android, Android TV, and iOS.
  • Enterprise solutions: Office management tools, booking systems, and corporate scheduling platforms.
  • Optimisation and Testing: Improvement of core app functionalities by up to 60% and implementation of unit testing to reduce QA workload by 30%.
  • CI/CD Infrastructure: Technical collaboration for automated deployments.
