Over four months, Jetrom contributed to the DayMarket/infra-docker repository by building and refining a robust, containerized data infrastructure. He implemented a Dockerized Kafka Connect pipeline that streams PostgreSQL changes into AWS S3 using Avro serialization, integrating Debezium for change data capture and optimizing connector configurations for reliability. Jetrom enhanced deployment workflows with CI/CD automation, improved frontend components with React and TypeScript, and resolved over 130 bugs to stabilize routing, UI, and build processes. His work emphasized maintainability, security, and reproducibility, resulting in a scalable foundation for real-time data ingestion and streamlined developer onboarding across backend and frontend systems.

July 2025 — DayMarket/infra-docker: Delivered an end-to-end Dockerized Kafka Connect CDC pipeline from Debezium PostgreSQL to S3 sink, enabling real-time streaming of database changes into a data lake with Avro serialization and AWS SDK integration. Reworked base images and connector configs for reliability, performance, and reproducibility. Hardened security by removing credentials jars and cleaning up sensitive references. Result: faster onboarding, scalable streaming infra, and a solid foundation for continuous data ingestion into S3 with consistent environments.

June 2025 — DayMarket/infra-docker: Key increments in reliability, data capture, and deployment efficiency. Delivered a User-facing Task Execution System (FixedExecutor) with a new exception hierarchy to improve robustness and readability of scheduled tasks. Resolved a Dockerfile runtime error caused by a typo (excetions.py). Hardened the build and deployment pipeline with CI/CD optimizations including offline npm caching, verbose npm ci output, longer timeouts, and minor code-style cleanups, boosting reliability and performance. Enabled near real-time data change capture by adding Kafka CDC integration with Debezium PostgreSQL connector via a dedicated Dockerfile setup.
