Experience

  1. NTT Data

    Software Engineer

    NTT Data — Oviedo, Spain

    Elevated to the core CENPOS initiative, the overarching ecosystem governing the entire residential management infrastructure for the Xunta de Galicia—spanning clinical administration, pharmaceutical inventory, and complex billing systems. This pivot marked a significant expansion in scope, bridging advanced technical execution with strategic Analyst-Programmer responsibilities.

    Driving technological modernization, I assumed the mantle of Technical Lead for the CENRES squad. My stewardship encompasses the full operational lifecycle: from architectural task estimation and validation to orchestrating daily stand-ups and mentoring of both intern and junior profiles.

    Furthermore, I manage critical CI/CD pipelines, executing production deployments for both CENPOS and CENRES, ensuring high-availability and fault tolerance for essential public services.

  2. NTT Data

    Junior Software Engineer

    NTT Data — Oviedo, Spain

    Achieved a record-breaking promotion to Engineer within just six months, driven by an exceptional capacity for complex problem-solving and delivery velocity. Spearheaded critical enhancements for CENRES, a high-stakes ecosystem managing the census and billing infrastructure for the Xunta de Galicia’s residential care network.

    Navigated high levels of abstraction to implement robust backend architectures using Spring Boot, while optimizing data transformation layers with MapStruct and Lombok. On the frontend, delivered resilient server-side rendering solutions using Thymeleaf.

    Transcended typical junior responsibilities by proactively assuming interim management duties. Steered team operations and decision-making processes during leadership absences, demonstrating the strategic acumen that catalyzed this rapid career trajectory.

  3. NTT Data

    Software Engineer Intern

    NTT Data — Oviedo, Spain

    Executed a strategic role in the development of a sovereign application for the Principality of Asturias, dedicated to the Integral Management of Minors. This high-velocity project offered a panoramic exposure to the full Software Development Life Cycle (SDLC), allowing for immediate impact beyond standard internship parameters.

    Leveraged a modern enterprise stack including Spring Boot and Angular to engineer resilient, full-stack solutions. Orchestrated data persistence and object mapping layers using Hibernate and MapStruct, while enforcing code cleanliness and API transparency through Lombok and Swagger.

    Championed functional excellence by actively participating in architectural decision-making and task refinement sessions. Furthermore, assumed a mentorship capacity for incoming talent, accelerating team velocity and fostering a collaborative engineering culture.
