What I'm looking for

I want to keep building end-to-end products—backend APIs, Angular SPAs, and ETL pipelines—while improving deployment automation, monitoring, and performance in cloud environments with clean, maintainable code.

I’ve built and rebuilt internal tools at Coinfirm Blockchain Lab and Lukka, including ETI Command Center, a Spring Boot system for remote process management and log retrieval for 120+ Reporting Agents.

At Coinfirm, I shipped the Data Entry Tool (DET) from a Laravel/JQuery baseline into a modern workflow with Selenium-based scrapers, MySQL/MapR persistence, and real-time alerting via the Slack REST API—cutting manual effort and speeding up data access.

Across projects, I’ve worked end-to-end with REST APIs, JWT session security, AWS infrastructure (EC2, EKS, S3), container tooling (Docker, Kubernetes), and observability/monitoring, focusing on maintainable code, reliable ETL pipelines, and faster troubleshooting.
