Includes serial job queue for background processing, role-based access, and KMZ export for SketchUp. Built with Claude Code as an AI pair-programming showcase.
ST Scheme
An R7RS-small Scheme language interpreter with both a terminal REPL and a browser-based IDE. Features a complete tree-walking evaluator with proper tail call optimization, a sophisticated numeric tower (arbitrary-precision integers, exact rationals, floats), and ~90 built-in procedures. The web app runs the interpreter entirely in WebAssembly with a dual-view IDE for editing and testing Scheme code. Includes an innovative three-tier environment system (full, hybrid, minimal) that demonstrates the relationship between language primitives and standard library.
ST Forth
A Forth programming language interpreter that runs entirely in the browser via WebAssembly. Features a split REPL + editor interface with live stack display and a 4-tier vocabulary system demonstrating how Forth builds itself from ~35 primitives into a full language. Includes a curated gallery of example programs and shareable program URLs with database-backed persistence. Also provides a terminal REPL for CLI use. Built with Claude Code as an AI pair-programming showcase.
ST Turtle
A web-based Logo programming language interpreter with interactive turtle graphics. Users write Logo programs in a browser-based code editor and watch animated turtle graphics draw on an HTML5 Canvas in real-time. Features 60+ built-in commands, procedure definitions with recursion, a curated gallery of example programs including classic fractals, adjustable animation speed, and shareable program URLs with database-backed persistence. UCBLogo-conformant with 155+ tests.
ST Brainfuck
A Brainfuck interpreter with a visual step-through debugger that runs entirely in the browser via WebAssembly. Features a tape visualizer showing cell values and pointer position during execution, configurable cell sizes (8/16/32-bit), speed-controlled stepping, and a curated gallery of example programs. Includes a primordial soup simulation mode inspired by the “Computational Life” paper. Also provides a terminal REPL for CLI use. Part of the Language Interpreter Series. Built with Claude Code as an AI pair-programming showcase.
photographyFYI
A comprehensive photography knowledge base covering cameras, lenses, film stocks, and techniques. Features a searchable database of equipment specifications, film characteristics, and technique articles for film photography. Sister site to darkroomFYI. Built with Claude Code as an AI pair-programming showcase.
ST Deploy
A read-only Kubernetes deployment dashboard for the Serbek Technologies Linode LKE cluster. Uses kube-rs reflectors to maintain an in-memory cache of cluster state, eliminating per-request K8s API calls. Provides real-time visibility into deployments, pods, services, and ingress across all project namespaces. Built with Claude Code as an AI pair-programming showcase.
ST Mailflow
A Gmail filter and label management tool that connects via OAuth to audit, analyze, and optimize email organization. Features AI-powered filter analysis using Claude to identify redundant rules, suggest improvements, and detect gaps in email routing. Provides a health score dashboard and supports bulk filter operations through the Gmail API. Built with Claude Code as an AI pair-programming showcase.
ST Spectral
A desktop application and CLI for processing infrared and ultraviolet photographs captured with a full-spectrum camera. Uses ML-driven 3D LUT generation via ONNX Runtime for intelligent channel remapping, turning raw IR/UV captures into natural-looking or artistically processed images. Includes plugins for Lightroom Classic and Photoshop integration. Built with Claude Code as an AI pair-programming showcase.
ST Architect
A native desktop 3D modeling application purpose-built for residential construction architects. Uses GPU-accelerated rendering via wgpu for a modern parametric modeling experience focused on component-based building assembly — walls, roofs, foundations, floors — rather than general-purpose freeform modeling. Built with Claude Code as an AI pair-programming showcase.
tradingAI
An options trading dashboard for analyzing, simulating, and managing multi-leg options strategies across brokerage accounts. Features real-time options chains, portfolio Greeks and risk monitoring, Black-Scholes pricing, and strategy backtesting. Built as a full-stack Rust application with a WASM frontend.
CIRM Grants Management System
Led all software development for the California Institute for Regenerative Medicine, a state agency funding stem cell research. Architected and built a proprietary Ruby on Rails grants management system with a metadata-driven framework that streamlined deliverable definitions and significantly reduced deployment time. Introduced a stereotype abstraction layer to enhance control over internal namespaces and accelerate deliverable deployments. Built RESTful JSON web services and Drupal data integration for the public website. Reimplemented high-traffic routes as React front-ends with asynchronous push-based updating for data-dense "air traffic control" style dashboards.
Later returned as a half-time retired annuitant to modernize the frontend with ViewComponent, Turbo, and Stimulus, replacing legacy jQuery code with encapsulated, reusable UI components. Built a full-stack Activity-Based Budget module and integrated Cypress end-to-end testing. Subsequently, reinstated as an ongoing half-time employee to continue leading development.
Goldfein Claims LLC
Built automation systems for an insurance claims business. Designed Ruby on Rails applications interacting via RESTful APIs with legacy business systems. Focused on OCR document processing using AWS Textract and Tesseract running in parallel, insurance tracking, and a partner-facing Claims API.
Scholastic SAM Enterprise
Led the software engineering efforts to create and maintain the SAM Enterprise Edition product line at one of the world's largest educational publishers. Directed the migration from a purely client-server deployment model to a full web-based curriculum delivery platform.
Kaplan Learning Management System
Built a seasoned engineering team from scratch and led all LMS development for one of the largest education companies in the world. Managed the migration of the development organization from Oakland, CA to divisional headquarters in Chicago, IL while maintaining delivery velocity.
Computer Curriculum Corporation
Led a team of developers creating a Windows and Macintosh client-server curriculum application system for K-12 schools. Subsequently directed the transition to a web-based curriculum delivery system, an early example of browser-based educational technology.
