Principal Software Engineer · Software Architect · Full-Stack & Systems Builder
Summary
I'm a principal-level engineer and software architect with a career spanning more than four decades of full-lifecycle ownership — from architecture through deployment, from sole developer to technical lead, from early microcomputer systems to cloud-native microservices. I've designed and shipped platforms that serve millions of devices and 20+ million subscribers, and I've done it while staying hands-on with the code.
I'm genuinely enthusiastic about where AI tooling has taken software development. I use Claude Code and similar tools as a force multiplier, not a shortcut — and I bring the architectural judgment to know the difference. My GoKart Factory project (see below) went from concept to a fully-tested, deployable full-stack application in under two working days. That's what AI-augmented development looks like when the engineer driving it has real depth.
I'm available for remote contract and consulting work. I'm not looking for leadership or management — I want to build things, solve hard problems, and work with people who value what deep experience actually produces.
Current Practice — AI & Modern Systems
AI-augmented development is the most significant shift in how software gets built since the advent of the internet, and I'm in it deliberately. I use Claude Code as a primary development accelerator — not for generating boilerplate, but for compressing the gap between architectural intent and working code. I've studied where the tools are trustworthy and where they require human judgment, and that critical perspective is as valuable as the acceleration itself.
My current practice spans both ends of the stack. On the web side, I build full-stack applications with AI-augmented workflows (see GoKart Factory). On the systems side, I write modern C++20 with ports-and-adapters architecture (see naTE, a graphical terminal emulator with full SSH protocol support). I'm also actively interested in AI integration work — building systems that incorporate ML pipelines, LLM APIs, and AI-native workflows into production applications.

Selected Projects & Accomplishments
A graphical terminal emulator built for engineers who live in SSH sessions — tiling layouts, multi-tab tile management, persistent workspaces, and a full suite of SSH features (agent forwarding, X11 forwarding, ProxyJump, MFA auth, SCP transfer) without touching the command line. A serious systems-level C++ project demonstrating current native fluency, network protocol depth, and architectural discipline.
- Modern C++20 codebase (98%+ C++); wxWidgets for cross-platform UI (Linux primary, macOS experimental)
- Hand-written VT100 / ANSI escape sequence parser, UTF-8 rendering, 100,000-line scrollback buffer with decoupled column-width and viewport
- Full libssh2 integration: password / public key / agent / keyboard-interactive (Duo, YubiKey, PAM) authentication; SCP transfer; auto-populates from
~/.ssh/config - Ports-and-adapters architecture — the headless core (parser, document model, session, transport) is entirely independent of the wxWidgets presentation layer and is in principle swappable for a different frontend
- CMake + Ninja build, Catch2 test suite, GitHub Actions CI, AppImage binary distribution
- 196 commits to date as sole architect, developer, and maintainer
A deliberate, rigorous experiment in AI-augmented software delivery. Built a full-stack electric go-kart manufacturing simulation from concept to fully-tested, deployable application in under two working days using Claude Code — not to showcase the AI, but to develop a clear-eyed understanding of where it accelerates delivery and where human architectural judgment remains essential.
- FastAPI backend with capacity-aware production scheduling, multi-tenant JWT authentication, and Gantt timeline visualization
- Vue 3 + Pinia frontend with full order management, factory configuration, and monitoring dashboards
- SQLite persistence, Dockerized deployment, full pytest + Playwright test coverage
- Documented findings on AI tool behavior: where trust is warranted, where architectural judgment is not substitutable
A polished demonstration of complex interactive data visualization in modern Vue. Renders astronomical time-series data (planetary positions over time) as a custom D3.js graph with a synchronized tabular view and on-the-fly analytical calculations. Built to demonstrate D3 fluency and loosely-coupled Vue 3 + Pinia component architecture.
- Vue 3 Composition API with Pinia for reactive state management and inter-component coordination
- Custom D3.js graph rendering with two selectable data perspectives and a lockable tracking crosshair for reactive point-by-point analysis
- ResizeObserver-driven responsive rendering; synchronized tabular view; user controls (date pickers, checkboxes, radio buttons) demonstrating reactive composition
- Companion ephemeris-api project provides the underlying time-series data
- Vite build, vanilla CSS (deliberately no CSS framework), live demo deployed at hovind.com
A visual personnel shift scheduler demonstrating maintainable web app architecture through direct manipulation. Drag-and-drop interactions replace traditional form inputs, illustrating how selection-based UX maps cleanly to underlying data mutations when the architecture is properly separated.
- Explicit separation of Display Logic from Business Logic — Pinia store owns the CRUD operations for shift assignments; presentation components remain free of business concerns
- Atomic component composition (Calendar Grid → Calendar Day → Shift; Server List → Server) — flexible, expandable, and easy to reason about
- Context-based mechanism for sharing display-only state (selection highlighting, drag preview) across components without polluting the business logic layer
- Works around a real Chrome quirk: the HTML DnD spec permits access to event data before drop, but Chrome restricts it — solved with a custom Context-passed event channel
- TailwindCSS applied within component
<style lang="postcss">blocks rather than utility-class soup, preserving HTML semantics
