Translating research-based logic into product experiences
I'm Dennis Saller, a product designer specializing in interaction design, prototyping, and learning-focused UX. I turn complex instructional logic into digital experiences that are more usable, more scalable, and more effective in the real world.
Why I Build
Research-based instructional logic is powerful — but it often lives in formats that don't scale. My work is translating that rigor into product experiences that are more usable, more scalable, and more effective in the real world.
I focus on the design layer where instruction meets product: interaction patterns, motion, and feedback systems that communicate clearly and reduce friction without sacrificing depth.
What I Do
Design disciplines I practice
Visual Design
Crafting clean, purposeful interfaces with refined typography, intentional spacing, and cohesive visual systems.
Interaction Design
Designing how products respond to users — from button states to complex flows — ensuring every action feels intentional.
Prototyping
Building high-fidelity prototypes to test ideas early, communicate vision clearly, and validate designs before development.
Motion & Animation
Using motion to guide attention, communicate state changes, and add personality that makes interactions memorable.
Alphabet Rebel
An iOS app for building fast, accurate alphabet sequencing automaticity.
The Problem
Many students can recite the alphabet but do not retrieve letter order automatically enough for fluent use in reading, spelling, indexing, and classroom tasks.
The Idea
Alphabet Rebel turns alphabet-sequencing practice into a fast, focused, game-like experience that strengthens automatic retrieval of letter order through before/after letter prompts.
Interaction Design
The app uses quick prompts, clear visual feedback, simple controls, and repetition with variation to build speed and fluency without unnecessary friction.
Why It Matters
Automaticity frees up cognitive resources for higher-level tasks. This project reflects my interest in designing tools that turn learning science into simple, usable, scalable digital experiences.
A motion-based learning app that teaches handwriting through guided animation and real-time feedback.
The Problem
Traditional handwriting instruction relies on static examples and verbal explanation. Children struggle to understand stroke order, direction, and proper letter formation without seeing the motion in action.
The Design Idea
LearnWrite uses animated demonstrations that show exactly how each letter should be written. A red dot leads the way, arrows indicate direction, and the stroke builds in real-time — making the invisible visible.
Interaction & Motion
Motion isn't decoration here — it's instruction. The animation speed, stroke weight, and guiding elements all serve a pedagogical purpose. Users can trace along, practice independently, and receive instant feedback.
Why It Matters
This project exemplifies my approach: using motion and interaction design to teach. The same principles apply to onboarding flows, complex forms, and any interface where users need guidance through unfamiliar territory.

About
A bit about me
I'm a product designer with a background in learning experience design. I've studied how people acquire complex skills — and that foundation shapes how I approach product design and interaction.
The core of my work is translating research-based instructional logic into product experiences that are more usable, more scalable, and more effective in the real world. I focus on the details that make systems work: motion that guides attention, feedback that confirms understanding, and interaction patterns that reduce friction.
I'm particularly interested in products where clarity and effectiveness matter most — where thoughtful design thinking transforms complex ideas into intuitive experiences.
Currently open to opportunities in product design, interaction design, UX, and design systems.
