Optimizing Human-System Interaction Through Research & Empathy

As a Human Systems Engineering specialist, I bridge the gap between cognitive science and user experience to design systems that truly serve people. My work integrates rigorous UX research with human-centered methodologies to enhance safety, performance, and emotional resonance.

About me

I am a passionate Human Systems Engineer dedicated to creating innovative and human designed projects. With a keen eye for detail and a deep understanding of user behavior, I combine creativity with strategic thinking to deliver impactful designs. My portfolio showcases a diverse range of projects that highlight my expertise in user research, prototyping, and visual design rendering. My work reflects my commitment to excellence and the ability to translate ideas into engaging digital experiences.

Driven by a curiosity for understanding user needs and behaviors, I approach each project with enthusiasm and a desire to solve complex design challenges. My process involves thorough research, collaboration with management, and a user-centered design approach. By incorporating the latest design trends and technologies, I ensure that my work not only meets but exceeds the expectations of users and clients alike.

Portfolio

Welcome to my portfolio, where creativity meets research and design. Here, you'll find a diverse collection of my written research samples, showcasing my analytical skills and depth of knowledge. Additionally, sample wireframes and prototypes that illustrate my process in crafting user-centered experiences can be found here. 

My portfolio highlights projects in three main areas
1) Research 2) Human Behavior and Action 3) Stakeholder Reports

Secureware

Secureware is a project that began in 2021, and is currently in its 13th iteration of design. Its focus is to ease the pain of hypermobility as it focuses on joint and ligament strain by focusing on weight distribution.

Mission

My mission is to design user-centered solutions that simplify and enrich interactions. I am dedicated to understanding user needs and translating them into effective, accessible, and visually engaging designs. Through continuous learning, testing, and iteration, I strive to deliver experiences that not only meet user expectations but also bring genuine value and ease to their digital journeys.

Vision

To create digital experiences that connect, inspire, and empower. I envision a world where technology seamlessly integrates into our lives, enhancing everyday interactions without complexity or frustration. By designing with empathy and clarity, I aim to make user experiences that feel intuitive and rewarding, so people can focus on what truly matters to them.

My Human Factors Journey

My journey into human factors began with a fascination for how people interact with the world around them—and how those interactions can be improved through thoughtful design. With a background in Human Systems Engineering and UX, I focus on creating user-centered solutions that are both effective and intuitive. I’ve led research to enhance mobility through wearable support devices and used AI to optimize navigation and reduce stress in high-traffic environments like theme parks. Whether I'm analyzing user behavior, improving accessibility, or streamlining team workflows, my goal is always to align systems with human needs in meaningful, impactful ways.

Empathy shapes every stage of my process. From conducting thorough user research to creating prototypes and testing them with real people, I work to ensure that each decision is centered on the user’s well-being. For me, improving Human Factors Design is about creating works that are both functional and emotionally resonate, offering people a seamless, enjoyable experience that leaves a positive impact.

Highly proficient using the following tools

Python

1.

Driven by curiosity and a desire to enhance my data analysis skills, I taught myself Python to automate workflows, analyze research data, and build prototypes. I regularly use it for statistical modeling, data visualization, and refining UX research processes.

AutoCad

2.

With a strong eye for precision and spatial reasoning, I use AutoCAD to translate design concepts into technical drafts. My experience includes creating accurate models and schematics that support ergonomic research and usability projects.

IBM SPSS

3.

I utilize SPSS to uncover actionable insights from complex datasets. Whether conducting ANOVA analyses or visualizing user behavior trends, I rely on this tool to support evidence-based decisions in human factors research and UX strategy.
