   Developed geospatial tooling on Amazon Linux and RHEL 9 by chunking large GeoJSON files with jQuery, converting them to Shapefiles via Python, and loading them into AWS Redshift for spatial queries. Built a Spring Boot application that authenticates to Redshift and exposes custom geospatial query endpoints with Swagger UI.Converted legacy NodeJS Lambda functions to Python, enabling S3-triggered workflows that post file contents to external services and archive processed files. Used CloudWatch to debug and harden all Lambda functions.Upgraded legacy SFTP Java processes during a company-wide migration from RHEL 7 to 8 by implementing modern authentication algorithms. Built GitLab CI/CD pipelines using custom Docker images, migrating Jenkins jobs into staged GitLab workflows and adding automated Dependency, SAST, and Secrets scanning across all repos. Managed Maven and Artifactory for reliable dependency and build management.Developed an event-driven AWS Lambda + SQS architecture that processes high-volume S3 file drops, forwards payloads through HTTPS, batches work, retries on failure, and archives results with full CloudWatch observability.Designed and delivered an enterprise-grade REST API for bidirectional SFTP file transfers (Java 17, Spring Boot, Spring Security OAuth2, JSch), featuring file pattern matching, filtering, AWS Cognito authentication with MFA, AWS Secrets Manager credential rotation, CloudWatch logging, JWT (Java Web Token) based auth with 60-minute expiry, Swagger UI, TLS/SSL, Spring Boot Actuator health checks, and ALB based high availability deployment.Additionally, built a CLI version of the enterprise SFTP platform with identical logic, authentication, and AWS integrations, providing all core file transfer capabilities without REST endpoints.
