- Tech lead in First Mile team leading a team of 6 engineers (distributed across Singapore, India and Indonesia) and involved in the technical architecture and design of the product features and engineering initiatives - Improved the p99 and p95 response time of the search functionality in Pickup Jobs page used by Operations staff to search for pickups to be done from shippers warehouses by about 15x by migrating the datastore from TiDB to ElasticSearch (Average RPS: 5000, p99 latency: 500ms) - Designed the workflow to send First Mile Pickup Receipts (consists of success and failed parcels picked up from shipper) for TikTok, Shopee and Lazada shippers every day (about 30k) via WhatsApp resulting in the onboarding of more shippers and an increase in the parcel volume by 5%. (Peak of messages processed: 1 million per day, Average of messages: 50K/min) - Designed the pipeline for integration of machine learning model with the backend system to identify similar addresses and merge pickups from similar locations to optimize on the number of driver trips being made and reducing the costs per parcel by 15x - Designed a Proof of Pickups(POP) auto-invalidation system with integration of Machine learning models to identify and reduce fake proofs uploaded by Drivers and inform the supervisors leading to an overall 94% valid fake proof detection. This involved building a generic platform called Jobber to execute any kind of jobs on Kubernetes including ML jobs and adopted by other teams as well for use-cases such as reports generation. - Took company-wide quarterly tech talks on: 1.
