Services
Engineering services, delivered remote
Four areas where I deliver as a remote contractor — each backed by production systems running today in regulated industries.
AWS Cloud & Serverless Backend
Design, build, and operation of AWS-native serverless and data-driven architectures — the core of my last five years of full-time work.
- Serverless system design: Lambda (Python and .NET), API Gateway, SQS
- Event-driven, high-volume asynchronous processing pipelines
- Aurora MySQL, DynamoDB, and RDS data modeling — including production RDS MySQL 8.0 → 8.4 migration
- S3 → Athena → QuickSight analytics and reporting pipelines
- REST APIs with Swagger/OpenAPI documentation
- CloudWatch monitoring and IAM-based operational ownership
.NET / C# Engineering
Twenty years of C#/.NET across desktop, services, and cloud — from WinForms client-server through modern .NET Core APIs.
- .NET Core REST APIs for regulated platforms (education loans, 401(k) transaction systems)
- WinForms desktop applications and Windows-service operational tooling
- Voltage Security field-level encryption for sensitive financial data
- Fortify security-finding remediation across distributed API systems
- Enterprise integration alongside ServiceNow and Salesforce CRM environments
AI-Enabled Application Development
Practical LLM engineering — not demos. Claude-powered systems designed for dependable, repeatable output in production.
- Claude API agent workflows, prompt design, and orchestration logic
- Production intelligent automation: document classification and extraction (Hyperscience + AWS)
- Real-time analytics dashboards (Python, Dash/Plotly) with LLM-assisted scoring
- Multi-source data ingestion with fallback providers for reliability and cost efficiency
Legacy & Mainframe Modernization
"Bilingual" fluency across mainframe and cloud — I can read the COBOL and design its serverless replacement.
- COBOL, JCL, CICS, DB2, IMS, and batch-processing fluency
- Strangler-fig migration of monolithic and batch workloads to AWS serverless
- Legacy database logic migrated to maintainable service-oriented architectures
- FHIR R4 healthcare data platform build (Lambda, RDS, self-hosted Medplum)
Working together
Engagement types
Project delivery
Fixed-scope builds: an API, a pipeline, a migration — delivered, documented, and handed off.
Staff augmentation
Embedded with your team on your backlog — comfortable in Agile/Jira environments, onshore or alongside offshore teams.
Advisory
Architecture reviews, modernization roadmaps, and AI-integration assessments.
