Software Development Engineer - III

● Completely re-designed and architected micro frontend architecture from their
monolithic web app. This reduced the time to release for marketing campaigns
from 2-3 days to a couple of hours. This reduced the dependency of marketing
team on the technical team which gave more options for making frequent
updates to content.
● Upgrade to NextJS from ReactJs app to deliver SEO optimized web app to
drive traffic. This improved our SEO rank and perceived latency to our end user
in a moderate network from 6sec to 2sec. Marketing pages with SSG capability
reduced the page load time to 1sec.
● Created deployment architecture for the micro frontends using jenkin as build
tool, create docker images and Kubernetes to manage pods. We used Sentry
to manage logs and error alerts. With the help of grafana we could check the
availability of our web application. We used AWS cognito to authenticate users
and deployed on ec2.
● Found bottlenecks in the code and made updates to reduce build time.
○ Changed SSGs to ISR where all the pages need not be built at build time.
○ Used esbuild-loader instead of babel-loader with webpack and that
reduced the build time by 50%.
● Lead a team of 6 engineers with responsibility of ticket breakdown and
estimation for product requirements.
● Upgraded to next13 to leverage react18 server side streaming functionality. It
boosted up perceived load time of components wrapped in suspense.
● Inculcated coding best practices and linting among team members to submit for code review with high quality and readable code.
