What I'm looking for

I am looking for a role in a mission-driven team where I can contribute to impactful projects and continue to grow my skills.

I am a dedicated software engineer with a strong background in entrepreneurship, currently pursuing my degree in Industrial Engineering at ITBA. My experience spans various roles, including technical lead and data engineer, where I have successfully contributed to mission-driven teams by building meaningful solutions. I thrive in dynamic environments, ensuring system reliability and optimizing workflows through innovative approaches.

At OpenKX, I co-founded an early-stage startup focused on AI-powered consultancy process automation, where I architected the core platform using Django Rest Framework and led a cross-functional product team. My role involved not only technical leadership but also managing stakeholder relationships effectively. I have a proven track record of designing and implementing data ecosystems that support automation and reporting needs, particularly in the fashion industry.

My journey has equipped me with a diverse skill set, including expertise in data pipelines, machine learning, and cloud services like AWS and Azure. I am passionate about leveraging technology to drive impactful solutions and am always eager to learn and grow within a collaborative team environment.
