About me

I'm a full stack developer looking for work mainly focusing on JavaScript language. React for frontend, Node.js for backend.

I'm usually on the computer most of the time coding and learning. When I'm not on the computer, I enjoy cycling.

I use VIM for coding and Emacs org-mode and org-roam for notetaking.

I am currently rocking a ZSA moonlander with Gateron Clear and Logitech MX Ergo for my peripherals.

Senior Software Engineer Jul 2022 - Jan 2024

  • Created an abstraction notification service for our team over an org-wide notification service using TypeORM, Postgres, AWS SNS and AWS SQS. This included planning multiple options, discussing with the team on the best option, executing the project, documentation on the usage of the API, making sure the queue runners metrics and alerts are properly tracked and set up respectively. Post deployment, we also needed to make sure that the overall performance of our APIs are not affected.
  • Upgraded our Cypress automation test suite to keep up to date with the org-wide's testing libraries as well as turning our CI/CD pipelines into reproducible YAML files to make it easier to scale
  • Implemented transactional outbox pattern to our API to ensure the reliability of our services. This included load testing our API with different configurations to ensure that there was no additional latency to our API. In order for safe deployments, this was released using feature flags where it could be roll backed quickly if something goes wrong.
