M.G. Network and Technology Solutions — I build practical software around real infrastructure: services that run on hardware I manage, with the auth, storage, backups, monitoring and runbooks done properly — not just the demo.

The three apps below run in production on a Mac mini at home, are open source, and have a documented way back up when they break. The fourth project is the Kubernetes staging platform built around them.

Tracks the stock trades of U.S. Congress members, corporate insiders (SEC Form 4) and institutional investors (13F) from their legally required disclosures. Scores every ticker on who is buying, weights each member by how their past buys actually did against SPY, and snapshots every score so the hit-rate of each label at 30/60/90 days is a number, not a claim. Live site — no account needed.

A Model Context Protocol server that lets Claude (or any MCP client) question InsiderTrack: "Where are several insiders buying their own stock this month, did anyone in Congress buy the same names, and how good is that member's record?" — three tool calls, one answer no page on the site can give. Read-only by construction, token-gated, rate-limited, audit-logged, stateless; eleven tools, two resources, two prompts.

Records a lecture from the browser (desktop or phone), transcribes it live with Whisper, writes structured notes as the class runs, and answers questions about it afterwards from the transcript, notes and slides. Exports to PDF, Word, Markdown, MP3, or the user's own Google Drive. In daily use for a graduate course since March 2026.

A Kubernetes (k3s) staging environment, managed with Argo CD, that runs copies of all three apps restored from the previous night's encrypted backups — with production credentials scrubbed from each copy. Every merge to main is built by CI, pushed to GHCR, and deployed to staging by Argo CD Image Updater committing the new digest to git, so git log is the deployment history; a weekly job restores both apps again and smoke-tests them. Built and verified in September 2026, then paused until it moves to its own machine — the write-up of why is in the repo. Production is watched meanwhile by Prometheus + Grafana on the Mac.

• Operations first: nightly encrypted off-site backups with a scripted restore drill, uptime monitoring, log rotation, a one-page operator runbook per project (what to do weekly, monthly, when it's down, when data is lost).
• Boring on purpose: pinned dependencies, Dependabot with CI-gated auto-merge, secret scanning, CodeQL, branch protection, semantic versions and changelogs.
• AI where it earns its place: pluggable providers (local Ollama, Claude, Gemini, OpenAI) with automatic fallback, routed per job so free local models do the bulk work and cloud keys are spent only where they matter.
• Developed with Claude Code as a pair-programming assistant; every feature came from real use and the problems it surfaced.
