Full Measure Apr'2021 - May'2021
Full measure is a platform for student engagements, enabling institutions to guide students through
admission, enrollment, and graduation, turning pivotal moments into opportunities for deeper, more
meaningful engagement.
● As a senior Ruby on Rails engineer, my main role is to oversee the legacy part of the product,
including maintenance, troubleshooting, and scaling services to accommodate increasing traffic.
● Working with the product team to devise and execute a safe transition from legacy services and clients into the new platform, ensuring stable service, and data integrity throughout the whole
process, so clients wouldn't even notice the transition.
● Main challenge is the usual challenge working with legacy codebase, the lack of documentation and history, which makes it very exciting to debug and track down bottlenecks, and even more
challenging to patch and fix issues without disrupting the running features.
