WORK HISTORY
Senior Python Developer @Shake Shack
Worked on building a centralized backend system for online ordering, POS integrations, and store operations using Python (FastAPI, Django), handling high-volume order traffic across multiple locations.Designed and implemented an end-to-end order management system covering order placement, kitchen workflows, and delivery tracking, ensuring real-time updates using PostgreSQL and Redis for low-latency performance.Built real-time event streaming pipelines using Apache Kafka and AWS Kinesis to process order events, delivery updates, and store-level activities, enabling live tracking and operational visibility.Developed data pipelines using Apache Airflow and PySpark to process sales, customer, and operational data, loading it into Snowflake and Amazon Redshift for reporting and analytics.Implemented an inventory and demand forecasting system using machine learning models (Scikit-learn, TensorFlow), helping optimize stock levels and reduce shortages across stores.Built a GenAI-powered intelligent search and support system using OpenAI APIs, AWS Bedrock, and LangChain, implementing RAG pipelines with Pinecone and FAISS for menu search and internal knowledge retrieval.Designed and deployed microservices architecture on AWS using services like EC2, S3, Lambda, ECS, EKS, RDS, DynamoDB, ensuring scalability and high availability of backend systems.Containerized applications using Docker and managed deployments on Kubernetes (EKS), enabling auto-scaling and efficient resource utilization.Set up and managed CI/CD pipelines using Jenkins and GitHub Actions, automating build, testing, and deployment processes across environments.Implemented monitoring and observability using Prometheus, Grafana, ELK Stack, and AWS CloudWatch, helping quickly identify and resolve production issues.Contributed to frontend dashboards using React and TypeScript for order tracking, store performance, and operational insights.
