Profile bio

About Brian Guth

I am a self-driven, confident, eager software engineer whose true passions lie in learning new skills and working with others. I believe that multiple engineers working together always make up more than the sum of their parts, and that the real fun in engineering and problem solving is collaborating with and learning from the person working next to you. My motto, both in engineering and in life, is that scary things are good for you; anything that gets you out of your comfort zone will help you learn and become a more well-rounded engineer and person as a whole.I excel with Java and related technologies such as Protobuf, Kafka, Spark, and Kubernetes/Docker, but am always excited to learn more about those and any others. I also have experience with Python, C++, JavaScript, and Swift.

A career timeline built from the work history available for this profile.

Senior Software Engineer

Deerfield, Il, Us

Led development and maintenance of core pharmacy Java services, including a service that calculates user roles and permissions at login based on complex legal and state-specific rules.Automated the process of updating business rules by creating a pipeline that converts Excel-based rule updates into JSON format, which were previously loaded as POM dependencies. This change reduced the SLA for deploying rule updates from 1-3 weeks to just 1 day by allowing the service to dynamically load rules from Azure Blob Storage at runtime.Created a comprehensive regression testing framework for the rules service from scratch using JUnit, enabling thorough testing of the rules engine. Configured the framework to test both local instances and remote services running on AKS clusters, ensuring robust validation of changes.Developed a secure file-processing endpoint that validates, compresses, and PGP-encrypts CSV files, integrating with Azure Data Factory for secure on-premises transfer.Maintained health and stability of lower environment AKS clusters, diagnosing and resolving service pod issues for consistent QA and team operations.Tech: Java, Azure (CosmosDB, Blob Storage, Data Factory), JUnit, Kubernetes (AKS), Spring Boot, Microservices, Docker, CI/CD Pipelines (ADO).
