Passionate software developer with a Master’s degree in Data Science.
I am a dedicated software developer with a Master’s degree in Data Science, combining a robust foundation in machine learning and artificial intelligence with practical experience in full-stack web development. I thrive on tackling technical challenges through thoughtful and efficient coding, and I am always eager to expand my skill set. My collaborative mindset and drive for innovation empower me to bridge the gap between intelligent systems and scalable web applications, ultimately building impactful, future-ready solutions.
At Variograma, I have contributed significantly to the development of both internal tools and client-facing applications, working across the full stack. My experience includes developing and maintaining backend services using PHP and MySQL, as well as building custom features within WordPress environments. I have implemented integration tests for APIs to ensure the reliability and performance of external service connections, demonstrating my commitment to delivering high-quality software.
Previously, I worked as a Consultant at Deloitte, where I developed and deployed business rules to enhance fraud detection processes and participated in the design and execution of interactive Power BI dashboards. My background also includes conducting comprehensive audits of IT General Controls at PwC, ensuring compliance with industry standards. I am passionate about continuous learning and am currently pursuing certifications in AWS, further solidifying my expertise in data analytics and cloud computing.
