Jael's profile

I'm Jose Antonio Escalante Lopez — Cybersecurity Developer & Data Engineer

embracing the never-ending journey of learning, developing, and evolving.

About

I'm a curious, values-driven IT professional who learns fast and never stops improving. What excites me most isn't proving expertise it's exploring what I don't know yet and turning that into working solutions. Over the last 2+ years I've built and optimized secure data pipelines (ETL, databases, automation) and worked across data engineering, cybersecurity, and system performance shipping changes that improved efficiency by up to 40% in banking/financial environments. I'm currently pursuing an MSc in Cybersecurity while working in Australia, because I believe this AI era demands multidisciplinarity, strong ethics, and a practical mindset.

I care about teamwork, honesty, responsibility, and the human side of technology. Give me a real problem and one fair chance I'll respond with curiosity, grit, and consistent progress. I'm not perfect, but I'm committed to learning, asking good questions, and improving every day. My motivation is simple: I love this profession. I want to build software, tools, and awareness that help people use technology safely and well. Outside of work I recharge with family, films, and philosophy, habits that keep me balanced, analytical, and creative.
