Work Experience

Software Engineer at Indra Sistemas S.A.

February 20, 2023 - Present

As a software developer in the Air Traffic Management domain, I design, develop, and maintain mission-critical Java/Spring systems across the full software development lifecycle. Key contributions include designing and implementing a FreeMarker-based API with a lightweight testing app that reduced active template developers from 15 to 5 and established me as the main technical contact; optimizing entity graph validations and Spring applications through algorithmic improvements, caching, and proxy reduction, achieving up to 60× and 30× faster execution in critical scenarios; overseeing Git repositories, reviewing and merging PRs, and delivering stable releases for a team of 10+ developers; and being finalist in the 2023 and 2024 Rising Star awards.

Control Engineer at Airbus Defence and Space GmbH

March 31, 2022 - October 15, 2025

Worked on development and verification of the constellation acquisition procedure for the LISA mission, integrating acquisition logic into the spacecraft control system. Implemented constellation acquisition algorithms in Simulink for end-to-end spacecraft simulation; conducted simulations to evaluate spacecraft behavior during acquisition and mission initialization; generated and validated flight code from Simulink models per mission software requirements; coordinated with team members to ensure consistency across parallel development and integration activities.

As a software developer in the Air Traffic Management (ATM) domain, I design, develop, and maintain mission-critical Java/Spring systems, contributing across the full software development lifecycle. Key contributions included designing and implementing a FreeMarker-based API with a lightweight testing app that reduced active template developers from 15 to 5 and established me as the main technical contact. I also optimized entity graph validations and Spring applications through algorithmic improvements, caching, and proxy reduction, achieving up to 60× and 30× faster execution in critical scenarios. I oversaw project Git repositories, reviewed and merged pull requests, managed integration and release branches, and delivered stable code releases across a team of 10+ developers. I was a finalist in the 2023 and 2024 Rising Star awards in the ATM division.
