What I'm looking for

I am looking for a product-led team that values ownership and autonomy in technical decisions, where I can contribute to impactful projects and continue to grow my skills.

As the founder and software engineer of Magoquiz, I have successfully built a profitable SaaS platform from the ground up, achieving remarkable results such as a 305× ROI and a 236% conversion rate boost for a key client in just 10 days. My deep expertise spans the entire JavaScript ecosystem, allowing me to architect and develop scalable web applications that meet the needs of the LATAM e-commerce market.

My experience at SYDLE further honed my skills, where I led the full-stack implementation of a pet healthcare platform, generating over 1 million monthly impressions. I thrive in collaborative environments and have a proven track record of mentoring new developers, driving architecture for major features, and ensuring high-quality releases through agile methodologies. I am passionate about leveraging technology to create impactful solutions that enhance user experience and drive business growth.
