Senior Backend Software Engineer at Coro who integrated Vertex AI into cybersecurity validation flows and built distributed Java services.

Germany
Message

At Coro, I designed and developed Java and Spring Boot backend services for cybersecurity products, including Data Loss Prevention and malware analysis. I integrated Vertex AI capabilities into backend validation flows to improve detection quality.

I built distributed microservices, REST APIs, and asynchronous workflows using MongoDB, Redis, and RabbitMQ. I also created Python CLI tools for security researchers and connected third-party services including VirusTotal and Bitdefender.

At Stampli, I independently designed and implemented the company’s first microservice to isolate the QuickBooks SDK integration from the monolith. I also built and owned a scheduled ETL pipeline that transformed DynamoDB data into tabular datasets for the BI team.
