2. Arbisoft on edX / 2U

   Senior Software Engineer · Lahore, PK (remote)

   Jul 2021 — Mar 2025

   3.5 years on the edX / 2U marketplace re-platform — payments architecture, OSS contribution, platform modernization. Grew from SWE to Senior SWE.

   • Spearheaded the integration of Stripe, PayPal, and wallets across edX's marketplace revamp.
   • Proposed a payments architecture with 3DS authentication that eliminated extra backend calls, webhooks, and third-party redirects — reduced cost and lifted checkout conversion.
   • Advocated for plugin-app architecture for openedX — separating business-specific code from the open-source core for security and compliance.
   • Led major version upgrades for Django, Python, Node and surrounding dependencies; spearheaded containerization and phased out legacy Ansible playbooks.
   • Implemented CI/CD with GitHub Actions and Docker; integrated DataDog and Splunk for monitoring, logging, and alerting.
   • Mentored junior engineers, ran code reviews for OSS contributors, and led client-facing technical discussions across teams in the US, UK, India, and South Africa.
