• Design, develop, consume, and support RESTful APIs for brokerage and financial services applications.
• Develop API integration solutions supporting request/response processing, authentication, authorization, error handling, exception management, performance, and resiliency.
• Design and implement event‑driven and asynchronous processing using EventBridge, SQS, SNS, Kinesis, and Lambda.
• Develop and support batch and file‑processing solutions including scheduled processing, file ingestion, file generation, and S3‑based processing.
• Develop large‑volume data processing solutions with appropriate error handling, reconciliation, processing controls, and restart/recovery mechanisms.
• Design and implement AWS Step Functions workflows to orchestrate multi‑step business and technical processes.
• Develop Lambda‑based workflows with conditional processing, branching, retry mechanisms, timeout management, and failure recovery.
• Integrate APIs, batch processes, event‑driven services, and downstream applications across complex enterprise environments.
• Monitor and troubleshoot serverless applications using AWS CloudWatch logs and monitoring tools.
• Perform Root Cause Analysis and resolve production issues across APIs, Lambda functions, messaging services, workflows, and downstream integrations.
• Develop solutions that are highly scalable, available, resilient, secure, and optimized for performance.
• Collaborate with architects, developers, business analysts, product owners, DevOps teams, and other technology teams to deliver end‑to‑end solutions.
• Participate in code reviews, technical design discussions, sprint planning, backlog grooming, defect triage, deployments, and production support activities.
• Follow Agile/Scrum development practices and contribute to continuous improvement of development and support processes.
