  Walmart Global Tech

  Nov 2023 - Jun 2024

  Software Developer

  As part of the AiOps division in Walmart's Platform Reliability Engineering team, I contributed significantly to the Anomaly Detection project. This internal product leverages Machine Learning models to identify anomalies in metrics emitted by Walmart's application teams, effectively reducing the time to detect (TTD) and time to recover (TTR) from incidents, thereby enhancing application availability and reducing human errors.💼 Work Highlights:- Designed and implemented the alert snooze feature: Enabled users to temporarily deactivate anomaly alerts, automatically reactivating them via a cron job upon expiration. This feature enhanced user engagement and significantly increased platform adoption across multiple internal Walmart teams.- Developed REST APIs: Facilitated the integration of Anomaly Detection models into Nucleus, Walmart's internal platform reliability tool, and helped transition existing Nucleus users to utilize Anomaly Detection services.- Created a daily cron job: Identified and removed inactive Prometheus (PromQL) queries and associated ML models, improving system efficiency by reducing the CPU usage of the anomaly inference service by approximately 15%.- Implemented Grafana dashboards: Enabled customers to monitor predictions, anomalies, and alerts generated by Anomaly Detection models for their services.- Developed middleware functions: Generated a unique requestId and logger for each incoming request, attaching the requestId to logs. This streamlined tracking across multiple services, facilitating quicker bug identification and reducing TTD and TTR by 30%.- Designed and implemented a Terraform Configuration File: Provisioned an Azure storage account dedicated to storing training data for models, ensuring efficient data management and accessibility.
