• Worked in Ask team which owns the Q&A feature in Amazon.com. Ask helps millions of Amazon customers get the answers they need to make informed buying decisions. Some products on Amazon occasionally invite controversy. To protect customers, Amazon will temporarily suppress the posting of reviews, questions, answers and comments for controversial items.
• Designed and implemented the Ask suppression tool for activism and pre-release products. Used an internal hierarchical database management system as a config store, to eliminate the code-build-deploy cycle thus making the process faster
• Implemented a read-only mode for the Ask widget to ensure that legitimate customers don’t lose out on helpful answers during the suppression period. Created a self-service UI with fine-grained permission controls to add/edit values
• Earlier the whole process of suppressing a widget and resolving a bug would take approximately 7-8 hours but this tool is able to achieve it in 5 mins. Was offered a full-time position after completion of internship
