About Alejandro

Why is the sky blue? 🌌

That question marked my childhood and led me to study physics at the Sorbonne. Years later, I realized it also defined my mindset: endlessly curious, deeply analytical, and always searching for better ways to solve complex problems.

Today, my porpuse is to create a positive impact through the ethical and human-centered use of AI and Technology.

As a professional I am passionate about scaling people and products. My focus is now on a long-term leading role where I can dedicate my unique blend of technical mastery, curiosity, and ethical commitment to building stable, high-performing teams and delivering measurable impact at scale.

¿Por qué el cielo es azul? 🌌

Esa pregunta marcó mi infancia y me llevó a estudiar física en la Sorbona. Años después, me di cuenta de que también definía mi mentalidad: una curiosidad incansable, un profundo análisis y una búsqueda constante de mejores formas de resolver problemas complejos.

Hoy, mi propósito es crear un impacto positivo a través del uso ético y centrado en el ser humano de la IA y la Tecnología.

Como profesional, me apasiona la escalabilidad de personas y productos. Mi enfoque actual está en un rol de liderazgo a largo plazo donde puedo dedicar mi mezcla única de maestría técnica, curiosidad y compromiso ético a la construcción de equipos estables y de alto rendimiento, y a generar un impacto medible a escala.

  • Limonísimo
    Founder & CEO
    HUMAN RESOURCES
    August 2025 - October 2025 (2 months)
    Humanizing Tech Recruitment with a Fresh Squeeze

    At Limonísimo, we decided to flip the script on the way tech talent gets hired.
    Why? Because traditional hiring processes were leaving everyone with a sour taste:

    🔹 Candidates exhausted by long, opaque, and impersonal processes.
    🔹 Companies wasting time and money on interviews that led nowhere.

    Our purpose is clear: to humanize technology and make recruitment fairer, faster, and refreshingly simple.
    With freshness, ethics, and boldness, we’re building a platform that:

    🟢 Cuts hiring times and costs.
    🟢 Eliminates bias, ensuring a fair and transparent process.
    🟢 Gives every candidate the chance to shine with their true talent.

    In short: we turn hiring tech talent from something sour into something refreshingly sweet.
