León Prieto
Software Engineer | MSc in Artificial Intelligence & Aerospace Engineering
Hi! I'm a software developer with an aerospace background, now fully focused on building modern applications and learning new, state-of-the-art technologies.
I started in aerospace engineering (BSc + MSc), then transitioned into software — a move that felt right, and where I’ve really found my place. These days I enjoy working with Java, Spring, Linux, and anything that mixes clean design with real-world impact.
Thanks for visiting — feel free to look around or say hello!

Professional Experience
Roles & responsibilities I've held professionally
Indra Sistemas S.A.
February 2023 — PresentSoftware Engineer
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.
- Designed and implemented a FreeMarker-based API with a lightweight testing app, enabling advanced template creation and allowing other teams to handle development independently. This simplified the workflow, removed the need for additional system interfaces, and positioned me as the main technical contact.
- 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.
- 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.
- Finalist in the 2023 and 2024 Rising Star awards, recognizing high-performing junior engineers in the ATM division.
Airbus Defence and Space GmbH.
October 2021 — March 2022Control Engineer
Worked on the development and verification of the constellation acquisition procedure for the LISA (Laser Interferometer Space Antenna) mission, integrating the acquisition logic into the spacecraft control system.
- Implemented constellation acquisition algorithms in Simulink for use within an end-to-end spacecraft simulator.
- Conducted simulations to evaluate spacecraft behaviour during the acquisition phase and mission initialization.
- Generated and validated flight code from Simulink models in accordance with mission software requirements.
- Coordinated with team members to ensure consistency and alignment across parallel development and integration activities.
