ARTSY

Salvaging the remains of an abandoned sensual creator platform project

A concept born from an ambitious adult creator-market platform that pivoted into a personal product exercise following a client bankruptcy. This project demonstrates how I streamlined an over-scoped feature set into a minimalist, media-first side project, focusing entirely on enabling artistic expression and designing subtle, premium monetization flows for a refined target audience.

Gynecologist

Optimizing the digital patient journey

A speculative redesign and retrospective of my first commercial web project from 2021, a live website for a local gynecological practice. This exercise evaluates my growth as a designer by auditing the UX and structural choices of my early engineering work and contrasting them with the modern design and user-centered strategy I would implement today.
