A step towards a modern stock trading platform
Kathleen Cuevas
A modern app for trading publicly listed companies on the Philippine Stock Exchange.
In a market where most brokerage platforms in the Philippines still look and feel like legacy software from the early 2000s, this project aimed to deliver the polish and clarity people expect from contemporary fintech—manageable, not overwhelming, and still respecting the complexity that stock trading demands.
The client has an existing web app but lacks essential features that could help traders make well-informed decisions. To address this, they wanted to develop a separate MVP app with key analytical tools, including a mobile-optimised experience.
The goal
Design a web and Android platform that helps traders make smarter decisions with clear, accessible tools for market analysis. The first features to tackle: a charting screen, watchlist, and instant price alerts.
The web app version. The client already has a list of requested features in mind and wanted a modern, "dark mode" look for this MVP app.
My role
Working directly and remotely with the CEO, I owned the end-to-end design across both platforms, solving product problems and building the underlying design system simultaneously.
The portfolio screen: describing the chart section in detail including its different state variants.
Mobile version
With the majority of the existing app's user base on Android, the client wanted to prioritise that platform first. I worked with the Material 3 design language for the Android app, which gave the interface familiar patterns and feel, while adapting it where needed to stay aligned with the web app's design system.

Structured for consistency and scale
Rather than building a design system upfront and hoping it fits, I let the product shape it. Every component designed — tickers, charts, portfolio rows — surfaced the shared decisions that needed to be tokenised.

Trading-specific building blocks and reusable components. Shared tokens, consistent output.
