Heo Jiin is a designer based in South Korea and Singapore,
working across design communication such as branding,
publication, creative coding, and UI/UX.
I am a designer based in South Korea and Singapore who sees design as a process of continuous discovery. My practice centres on exploring the unfamiliar and moving between different disciplines.
Recently I have expanded my creative scope through experiments with Arduino and 3D modelling, looking at how technology adds new dimensions to design. I am also interested in creative coding, character design, branding, and UX/UI. I aim to connect storytelling with functional solutions.
PROJECT 001 / 006
BLAH BLAH LAB is a lifestyle brand that helps individuals embark on a journey of self-discovery and emotional awareness. The name comes from the narrative of a science lab creating emotion monsters — “BLAH BLAH” means to not be afraid to face your emotions and talk about them.
PROJECT 003 / 006
Supporting digital wellbeing through hybrid interventions grounded in Self-Determination Theory.
RE:MEDY is a hybrid design intervention developed to resolve the ‘Digital Detox Dilemma,’ addressing the irony of relying on apps to stop smartphone addiction. Grounded in Self-Determination Theory, this project moves away from restrictive and screen-based tools that lead to stress and user fatigue. By shifting the focus from the screen to the physical space, RE:MEDY helps users disconnect from constant notifications and doomscrolling, reclaiming time for self-reflection and intentional rest.

PROJECT 002 / 006
A tangible habit companion that turns daily routines into a living garden. Tap a physical NFC keychain to start a mission, and a small character grows alongside your progress.
Habit Garden is a habit tracker that actually feels like a game. Instead of navigating through endless digital menus, you initiate your focus time by simply tapping a tactile NFC keychain. This physical action connects directly to a Tamagotchi-inspired world. Completing offline activities earns you EXP as a reward, allowing you to nurture your pet from a sprout to a fully evolved character. Built on positive reinforcement, the system never penalises you for short sessions. Every small attempt builds up, making habit-building a long-lasting, enjoyable journey.
PROJECT 004 / 006
A typeface designed for each month, built from geometric shapes. When the months overlap, the cut-out numbers appear to rotate around the circle, and each sheet doubles as a paper swatch for RJ Paper.
PROJECT 005 / 006
Campaign and branding design for SPCA Singapore.
PROJECT 006 / 006
Side studies, prototypes and self-initiated tests. Making abstract ideas into reality.
A simple math game built with Claude Code as a part of my experimentation projects for AI in education. An ongoing experiment with vibe coding to make learning fun and enjoyable.
A single button becomes the thin barrier between inner emotions and outer composure. Pressing it bottles feelings up, represented by shapes that pile and multiply on screen. Releasing the button lets the circles fade, visualising the slow release of what was held in.
