Experience
Fintech Startup
A mobile app for money management, budget tracking, and investments. I helped improve the app features and design. I then brought it to market as part of several integrations with Clearbank, Apple Pay, and Google Pay.
Team Collaboration Tool
Helped a team improve the security of their cloud-based app and get the changes live. This tool enables teams to collaborate more securely by providing individuals and groups control over the data they have access to.
Big Data
I contributed as part of a team that develops microservices that are hit by millions of users per minute—this generates tons of data that gets processed by the servers. I improved the number of required instances in AWS by constantly trying to find the right balance between memory, CPU, and types of instances.
OKR App
Migrated the UI testing framework for an OKR tool from Protractor to Cypress, using JavaScript while taking care in parallel of a load testing framework using K6. I then set up the required jobs in CircleCI, along with reporting capabilities.
