Migrated a Strapi setup from AWS to Azure services
Aug, 2023 - Sep, 2023

  • Modifying code to leverage the equivalent Azure services (while handling Cloud provider specific differences).
  • Migrating the existing data & files from AWS to Azure.
  • Performing the storage migration (Terrabytes worth of data) with a minimal downtime via feature-flag driven development.

Strapi Upgrade

Undertook v3 => v4 upgrade for a complicated CMS setup
May, 2023 - July, 2023
This Strapi upgrade was more complicated than the ones I executed earlier:
  • The setup (in use since 2019) had many data inconsistencies (orphan records, foreign key violations) needing pre & post data-processing.
  • The large number of dynamic zones & relationships transated ~60 collection types into ~1k postgres tables being migrated.
  • The global all-remote team with members working in many timezones demanded prompt communication for a timely execution.

  • Configured image optimization + caching for faster image loading.

CMS Framework Selection

Undertook a proof-of-concept to identify suitable CMS framework
Nov, 2022 - Dec, 2022
Having worked on multiple initiatives for this B2C org, I was tasked to provide tech inputs wrt. selecting JS based headless CMS framework:
  • Gathered must-have & good-to-have requirements from various stakeholders.
