Project : Multi Account migration - The Bank of Montreal.

Developed and maintained backend API services using Node.js integrated with multiple AWS cloud components to support secure and scalable banking operations.

Implemented AWS SNS (Simple Notification Service) and SQS (Simple Queue Service) for reliable message queuing and asynchronous event communication between microservices.

Built and deployed AWS Lambda functions to handle serverless compute operations and background processing tasks.

Managed user access and security permissions using AWS IAM (Identity and Access Management) for controlled resource access.

Utilized AWS DynamoDB for storing and retrieving structured data with high availability and low latency.

Integrated downstream APIs to communicate securely with other banking systems and services.

Monitored application logs and performance metrics using AWS Cloud Watch for proactive issue detection and troubleshooting.

Utilized AWS S3 for storing and managing configuration files, logs, and application data.

• Provisioned, configured, and maintained EC2 instances across multiple Availability Zones to ensure high availability and disaster recovery readiness.
• Designed and managed secure virtual network environments using VPC, including subnets, route tables, and NAT Gateways.
• Implemented Elastic Load Balancers (ELB) (Application and Network Load Balancers) to distribute traffic efficiently across backend instances.
• Configured Auto Scaling groups with dynamic scaling policies to automatically adjust compute capacity based on Cloud Watch metrics, optimizing cost and performance during peak loads.
• Administered object storage using S3, configuring bucket policies, versioning, and lifecycle rules for data security and cost optimization.
• Managed relational database services (RDS) for application data, including backup strategies, scaling, and read replica configurations.
• Created and managed event-driven serverless functions using AWS Lambda to handle background processing, data transformations, and API backbends, significantly reducing operational overhead.
• Configured SNS for pub/sub messaging and notifications, enabling asynchronous communication between application microservices and system events.
• Enforced the principle of least privilege by configuring policies and roles within IAM to secure access for users, services, and applications across the AWS environment.

• Diagnosed and resolved technical issues for hardware and software systems.
• Provided exceptional customer support via phone, email, and chat channels.
• Documented troubleshooting processes and solutions in knowledge base articles.
• Collaborated with cross-functional teams to enhance product performance and reliability.
