George Hinkel

Active technical research and systems administration during career sabbatical.

• Built and maintained a personal dual-boot workstation (Windows/Fedora) with LUKS encryption and Btrfs filesystem management.

• Developed economic analysis models using Python (Pandas/Matplotlib) to evaluate inflation, sovereign debt, and market data over time.

• Created complex Datalog queries in Logseq to organize personal knowledge bases and research.

• Experimented with Google Antigravity agentic LLM AI IDE to generate prototype applications using a review-driven workflow.

• Experimented with running LLMs locally on personal hardware utilizing open-weight models from HuggingFace running with Ollama. Integrated these models with open-source chat frontends as well as code generation CLI tools.

Fullstack development in Java (Spring Boot) and TypeScript (React).

• Maintained Java Spring Boot backend and React TypeScript frontend services.

• Used LLM code generation to accelerate development of SQL queries and Java boilerplate.

• Managed CI/CD pipelines via Github Actions using on-prem runners.

Fullstack development in Java, Python, and TypeScript on the AWS platform using AWS CDK.

• Built and maintained high throughput Java services (>10k TPS) on AWS. Integrated SageMaker ML models into production traffic, using shadow testing to validate ML results against the previous rule based methods.

• Architected cloud infrastructure using AWS CDK (Infrastructure as Code) to manage EC2/ECS containers, Lambda functions, and CI/CD pipelines.

• Designed a single-table DynamoDB schema to handle complex domain configuration data.

• Created a configuration management web app with a Dockerized Java backend and a TypeScript/React frontend.

• Built internal CLI tools in Go and Python to automate service tasks and interactions.

• Set up data streaming pipelines using Kinesis, Glue, and Athena to analyze test results and service metrics.

Software Development for systems of systems interoperability (STITCHES) on DARPA's SoSITE program.

• Developed critical system integrations enabling communication between legacy hardware (Link 16) and modern protocols (Kafka/REST/gRPC).

• Built a prototype of a Java-based language server and CLI tools (Bash/Python) to improve developer experience for the custom STITCHES DSL.

• Implemented automated code generation pipelines using Swagger/OpenAPI to create client libraries for REST and Kafka interfaces.

• Managed CI/CD workflows in GitLab CI, creating Dockerized build environments for the STITCHES toolchain which greatly improved portability.

REST microservice backend development for financial advising software using Open API in .NET Core and Framework.

• Migrated monoliths to C# microservices and integrated with Microsoft Dynamics 365 CRM.

• Led effort to migrate a key microservice from .NET Framework to .NET Core.

• Automated testing using NUnit and Moq.
