Fredrick Hilarian:
Architecting the Future of Digital Experience.
Product Designer & Engineer
Product Designer and Engineer with 5+ years of experience designing and building scalable, system-driven digital products from concept to production. I specialize in simplifying complex workflows into intuitive user experiences across B2B SaaS and data-intensive platforms.
I work end-to-end, translating ambiguous problems into structured user journeys, scalable design systems, and production-ready interfaces. With a strong engineering background in Next.js and Node.js, I bridge design and development to ensure high-quality execution. I’ve contributed to products for global brands like Samsung and Apple Care, driving measurable improvements in engagement, performance, and usability across multilingual platforms, while leveraging AI-assisted workflows to accelerate design and iteration.
What I Build
I transform complex systems into intuitive digital experiences by combining product thinking, scalable design systems, and production-ready engineering.
My work focuses on three core areas:
Product Design
Designing scalable SaaS platforms and enterprise interfaces that simplify complex workflows while ensuring WCAG 2.1 AA accessibility standards.
Design Systems
Architecting modular UI systems using Figma variables and design tokens to ensure consistency, speed, and platform-agnostic scalability.
Full Stack Engineering
Bridging design and development by translating high-fidelity Figma systems into production-ready React/Next.js interfaces with semantic ARIA support.
Selected Product Outcomes
Across multiple SaaS and enterprise platforms, my work focuses on improving usability, performance, and product scalability.
Social Proof
"Products I’ve worked on have supported global brands including Apple Care and Samsung."
A Legacy of Innovation.
Over the past five years, I’ve worked across startups and enterprise teams designing and building scalable digital products.

Beyond the Code.
Great digital products emerge where design, technology, and storytelling intersect. I explore typography systems, visual storytelling, and AI-assisted creative workflows to build richer digital experiences.
From refining Figma component libraries to experimenting with generative AI tools, I constantly push the boundaries of how design and technology interact to shape the next generation of digital products.
