My work here at Rooter,-> Led the redesign of Rooter's video / reel content upload system utilising S3 multipart upload, which pushes an SQS event and triggers transcoding. Worked in a team of developers to quickly bring it live on production.I am currently working on improving the overall system. Aim is to reduce transcoding time and delivery bandwidth while keeping the same video quality. We have moved to k8s jobs to create a separate transcoding job for each transcode.-> Revamped the live stream chat and scaled the service to over 100k requests per second. Tech used - NestJS, Typescript, Redis, gRPC and websockets.Also migrated the system from MySQL which was causing scaling issues. Designed the schemas and participated in the migration of data from MySQL to MongoDB.-> Developed stream moderation for live chat. Streamers can select moderators to regulate their chat by deleting nuisance comments and banning repeat offenders.-> Developed a clickstream service to track user activity on the platform of more than 200k concurrent users in real time using WebSockets. All logs were then pushed to Kafka topics.-> Developed a real-time E-sports match updates delivery for Rooter's newest offering, e-sports scorecard like Cricbuzz is for cricket. link - stade.ggUtilised WebSockets and Pub-Sub to scale this system to over 4k concurrent users.- Designed and developed a stream download feature for creators which transcodes recorded streams to MP4 and generates a download link asynchronously.- Developed growth dashboard to track downloads, sign-ups and D1 metrics for influencers utilising AWS Redshift.
