• Some important Contributions to A/B test platform:
• 1. Owned Experimental platform - Data layer (Data flow, Metric Metadata , Metric result calculation, Storage, How to expose result to UI through Api etc).
• 2. Worked on A/B testing hygiene to the Experimentation platform like : Metric result correction, Significance Calculation (two-part test) integrations, Experiment pre-biasses (Bucket Switching, SRM and Novelty effects etc) Visibility and monitoring / alerting, Feature developments , Involved in design discussion (Low + high + data flow) with multiple teams and PMs and Presented the product in tech talks in org.
• 3. Redesigned Data Layer (user and metric table) of A/B test platform, which reduces size by 80% in memSql and improved reporting query performance.
• 4. Reduced 70% cost and 66% processing time of Data Processing Workflow (Spark) for Experimentation (A/B test) platform.
• 5. Builded Spark pipeline for AWS MemSql data migration to Azure cloud MemSql for around 2200 Millions records (10 TB size).
• Other than A/B platform, I was activity involved in AWS to AZURE cloud migration activities (micro-services , spark jobs ,data), validations and deployments etc.
• I got chance to contribute in Dash-boarding and Personalized Segmentation Platform. In Dash-boarding platform, I have developed a micro-service to provide a downloadable link (of resultant dataset as csv) based on provided input (as DB source and Query), In Personalized Segmentation platform, I developed SQL query based Segment creation flow.
• I was actively involved in On and Off campus hiring for Software engineer and Senior software engineer roles.
