Open Source Projects
I design open-source tooling focused on runtime data modeling, service boundaries, and operational clarity. These libraries reflect the systems I build in production: typed data at the edges, controlled mutation, and explicit execution flow.
Cattri (Ruby)
A lightweight Ruby DSL for defining class and instance attributes with strict semantics. Supports inheritance, lazy defaults, final (write-once) values, and fine-grained control over visibility and coercion. Designed for building predictable, introspectable runtime state.
Castkit (Ruby)
A type-safe DTO and contract system for Ruby services. Provides declarative schemas with typecasting, validation, and serialization, built to harden service boundaries and reduce implicit coupling.
Gaskit (Ruby)
A framework for composable operations and service objects. Structures business logic as step pipelines with early exits, explicit error handling, and integrated logging + duration tracking for production observability.
Corbel (Python)
A composable dataclass extension and runtime modeling toolkit for Python. Provides mixins for validation, immutable updates, hashing, comparison, and JSON serialization, plus property-level metadata via @corbel_property. Designed for structured data modeling with minimal overhead.
Obfuskey (Python)
A compact library for reversible, fixed-length obfuscated key generation from integers. Supports bit-packing multiple values into single compact identifiers using custom schemas.
Obfuskey.js (TypeScript)
A cross-platform port of Obfuskey for JavaScript and TypeScript. Provides reversible fixed-length identifiers and bit-packing with BigInt, enabling safe use across frontend, Node, and edge runtimes.
These libraries were developed independently and are not affiliated with any employer. Each reflects my focus on clarity, performance, and long-lived system design.
Experiments
IsNathanAlive
(Live Site) — Next.js / IoT
A playful status-check site integrating a SwitchBot motion sensor, Vercel serverless functions, and Upstash Redis. Motion updates a timestamp that renders as a large, humorous status message (e.g., “got dunks 2 days ago, still kickin”).
Demonstrates practical use of IoT webhooks, event filtering, and near-real-time serverless data flow, wrapped in a deliberately absurd interface.
