Open source libraries, developer tools, and experiments. All personal work. Some inspired by patterns from professional engagements, shared carefully and anonymously where relevant.
Everything here is built out of personal curiosity, passion, and the joy of solving hard problems. These are side projects, experiments, and explorations — conceived, designed, and built entirely on my own time.
A generic, data-driven pub/sub event system where publishers, subscribers, and handlers are all defined in database configuration — zero hardcoded wiring. Drop a row in a config table and the system routes, transforms, and delivers events dynamically via Azure Service Bus. Built-in handlers for Email, Logging, HTTP callbacks, Stored Procedures, and custom processing — fully plug-and-play.
A full-stack, cloud-native platform built on a security-first architecture. Implements row-level security, fine-grained IAM policies, Cognito-based authentication with MFA, and Textract-powered document intelligence. Containerized API on App Runner with CDK-managed infrastructure, React SPA frontend, and RDS-backed persistence.
Full-stack photography business platform for gallery management, secure client sharing, and print sales. Features passcode-protected galleries, Stripe payments, zip downloads, and an admin dashboard with analytics. Built on React/Vite with C# .NET Lambda functions on AWS.
Crowdsourced bridge structural health monitoring using smartphone accelerometers. Users cross bridges and the app records vibration frequencies — shifts in natural frequency indicate potential structural change. A digital twin for civil infrastructure, discovered organically as users cross bridges worldwide.
A generic, extensible repository pattern implementation for .NET with first-class support for stored procedures, Enterprise Library data access, and a clean separation between interface and implementation.
Reusable YAML pipeline templates for .NET applications. Build, test, security scan, and deploy to multiple environments with a single include. Supports multi-stage deployments with approval gates.
A lightweight .NET CLI tool for versioning and deploying stored procedures to SQL Server environments. No full ORM dependency. Schema drift detection built in.
A small .NET library for structured, semantic error handling. No more exception inheritance trees. Result types with explicit error categories that propagate cleanly through all application layers.
A set of PowerShell scripts for automated SQL Server backup, verification, and offsite transfer. Superseded by better native tooling — archived for reference.
Lightweight .NET middleware for proactive API performance monitoring. Latency percentiles, slow query detection, and structured alerting — built in, not bolted on.
