Building reliable, accessible web platforms.
I’m Karl — a full‑stack engineer building performant, accessible platforms at NASA’s Goddard Space Flight Center. I ship mission‑critical apps, mentor teams, and turn complex ideas into usable products. Beyond code, I volunteer with the Renwick Gallery and the Smithsonian American Art Museum, and I compose and perform music.
Portfolio
A brief, curated list of projects I've worked on over the years in professional settings.

Earth Science Communications Content Registry (ESCCOR)
ESCCOR is a cutting-edge platform revolutionizing Earth science data management. This system integrates advanced taxonomy, AI-powered indexing, and a high-performance catalog, accessible through a user-friendly portal. ESCCOR enhances NASA's Earth Sciences Division's reporting, product access, and cross-team collaboration, positioning NASA at the forefront of Earth science data management. My work significantly improved NASA's handling of vast science information, benefiting multiple NASA groups and advancing the agency's mission. Together, these innovations make critical data more discoverable, usable, and impactful than ever before.

Website & Backend Administration
I helped develop NASA's Earth Observatory website and its advanced back-end system, creating a digital gateway to NASA's environmental research. This platform showcases stunning imagery, compelling stories, and crucial discoveries about Earth's ecosystems and climate from NASA's satellite missions and field research. Using cutting-edge web technologies, we crafted an immersive interface that brings complex scientific data to life for a global audience, supporting NASA's mission to foster public understanding of our planet's intricate systems and environmental changes. The site serves as an invaluable resource for scientists, educators, policymakers, and the public alike.

Tool for Building Enterprise Applications
At Dante Inc., I contributed to Taylor MDA, an advanced Eclipse-based UML modeling tool for multi-tiered, distributed systems. It streamlines complex system design and maximizes code generation from UML models. Taylor MDA features pre-designed templates for JEE applications, integrating JPA/EJB3 and JSF/Seam/Facelets, accelerating enterprise application development through innovative model-driven architecture techniques. My work enhanced its capabilities and user experience.

Application & Backend Administration
Verizon Business Finium™
Verizon Business' Finium™ platform transforms cybersecurity by unifying threat intelligence, vulnerability data, and security events in a centralized web console. Built on a disaster-resilient Security Operations Center, this advanced system empowers analysts and business leaders to treat security as a strategic asset. My work on Finium™ helped reshape enterprise cybersecurity, making it more accessible and integral to business operations in today’s digital landscape.
