Built with: TypeScript, Node, MCP, MIT. - Project page: https://kylebegeman.com/projects/ledger/ - View on GitHub: https://github.com/kylebegeman/ledger - Live reader: https://kylebegeman.github.io/ledger/ ### Dossier Open Source · v0.7.3 · Pre-1.0 Open-source Go binary with a CLI, an MCP server, and an agent skill that turns agent-written JSON into one self-contained, searchable HTML page, with decisions a reader makes by number and the agent applies. Built with: Go, MCP, SQLite, MIT. - Project page: https://kylebegeman.com/projects/dossier/ - View on GitHub: https://github.com/kylebegeman/dossier - Live examples: https://kylebegeman.github.io/dossier/explore.html ### SwiftLM Open Source · v2.0.0 · Stable Open-source Swift package, the layer a language model feature needs around the model: local first, with cloud providers only when an app lists them, and no network access or telemetry in the core. Built with: Swift, Foundation Models, SwiftPM. - Project page: https://kylebegeman.com/projects/swift-lm/ - View on GitHub: https://github.com/kylebegeman/swift-lm ### Helios Open Source · v0.7.13 · Pre-1.0 Open-source Go rewrite of Ophelia that runs my production machine: an app's helios.yaml becomes DNS records, certificates, secrets, isolated containers, backups proven by restore drills, and alerts. Built with: Go, Docker, Caddy, restic. - Project page: https://kylebegeman.com/projects/helios/ - View on GitHub: https://github.com/kylebegeman/helios ## Open source ### Ledger Change memory that lives in your repository. TypeScript · MIT · v0.9.5 · Pre-1.0 A diff shows what changed. Ledger keeps why it changed, what must stay true, and how it was checked. Markdown receipts live beside the code, so the next person or coding agent starts with the evidence. I built the CLI, agent integrations, and reader around that same record, with no account or hosted service required. - Context before the edit: Retrieve history for a file, symbol, or topic within a token budget. Packets bring the relevant decisions, invariants, and verification into the next session. - Receipts while the work is fresh: Hooks for Claude Code, Codex, and Cursor track edits and draft a receipt. The author finishes the reasoning; the ready check catches unfinished content. - Evidence in the pull request: CI checks record structure, file coverage, and docs impact. Receipts travel through review with the change they explain. - Your history, your files: Plain Markdown under .ledger/ is the source of truth. Keep durable guides in docs/ and rebuild the reader, indexes, and reports whenever you need them. - Repository: https://github.com/kylebegeman/ledger - Project page: https://kylebegeman.com/projects/ledger/ ### Dossier One JSON model in, one self-contained HTML page out. Read, decide, and send it back. Go · MIT · v0.7.3 · Pre-1.0 Agents can produce a lot of text. Dossier gives that work a shape people can read and act on: a clear masthead, numbered sections, detail behind a fold, and decisions by number. I built it as one Go binary that turns a JSON model into a self-contained HTML page, then brings the reader’s decisions back into the model. - Six kinds of work: Brainstorm, plan, review, release, incident, and brief have their own vocabulary and decisions. Define a custom kind in one JSON file. - One file you can send: Built pages make no external requests. Share an attachment, a CI artifact, or a static page; search, dark mode, print, and the embedded model come with it. - Decisions an agent can use: Numbered choices, verdicts, and notes become one reply line, with the same reply explained in plain words. Apply it back to the model with the CLI. - More than prose: Use tables, highlighted code, charts, timelines, figures, and DOT or Mermaid diagrams rendered as SVG at build time. Export Markdown for a pull request or wiki. - Repository: https://github.com/kylebegeman/dossier - Project page: https://kylebegeman.com/projects/dossier/ ### SwiftLM One Swift API for every language model your app can reach, with prompt contracts, token budgets, explicit fallbacks, and redacted receipts. Swift · Apache-2.0 · v2.0.0 · Stable SwiftLM is the layer a language model feature needs around the model: a prompt you can version, a context that fits, a next step when the model can't answer, and a record of what happened. One Swift API reaches Apple's on-device model, Private Cloud Compute, custom Core AI or MLX models, OpenAI, and Anthropic. The on-device model is the default, cloud providers run only when an app lists them, and the core has no network access and no telemetry. Version 2.0 renamed the package from SwiftLLM, since it handles models of every size, and adopted the OS 27 Foundation Models framework. - One API, every model: Apple's on-device model, Private Cloud Compute, any OS 27 LanguageModel such as Core AI or MLX, OpenAI, and Anthropic behind one client that streams. - Local first, cloud by choice: The on-device model is the default. Private Cloud Compute and cloud providers run only when listed, and every client reports where content goes. - Fallbacks with reasons: Routers skip models that can't honor a request and move on after quota, context, and availability errors. Refusals and bad output stop the run. - Prompts and budgets: Versioned prompt contracts, token budgets with reports, boundary-aware chunking, and context packing that fits the model's window. - Checked output: Schema descriptors, validators, and repair policies for structured generation, plus source-aware local retrieval with citations. - Receipts and evaluation: Every routed run leaves a receipt with no prompt or response text in it, and evaluation cases replay a feature when a prompt or a model changes. - Repository: https://github.com/kylebegeman/swift-lm - Project page: https://kylebegeman.com/projects/swift-lm/ ### Helios One small program that runs your machines: builds, certificates, secrets, backups, health checks, and alerts from a single static binary. Go · Apache-2.0 · v0.7.13 · Pre-1.0 Helios installs and operates a whole machine from one static Go binary, with no agent, runtime, or hosted control plane underneath. Each app describes itself in a helios.yaml, and everything follows from that file: DNS records, certificates, secrets, data services, health checks, backups, and alerts. Containers are isolated by default, backups are proven by scheduled restore drills, and a git push deploys with every step streamed back. It is the Go rewrite of Ophelia, and it runs my own production machine. - One binary: A static Go binary installs and operates the machine. There is no agent to babysit, no runtime to keep current, and no control plane to pay for. - The manifest is the interface: helios.yaml declares workloads, routes, secrets, data, backups, and checks, and helios init writes a validated starting file for each kind of app. - Isolated by default: Read-only root, no Linux capabilities, no privilege escalation, a non-root user, and a private network per app, with helios exposure to show what each container got. - Deploys without a pipeline: git push deploys and streams every step back. A failed deploy refuses the push, and the previous revision stays ready for rollback. - Backups that restore: Consistent, encrypted restic snapshots per app, restored beside the app, started, and verified by scheduled drills. - Plans you approve: Every machine operation can show its plan first and then apply only that exact plan, named by its digest, so a person or an agent approves what runs. - Repository: https://github.com/kylebegeman/helios - Project page: https://kylebegeman.com/projects/helios/ ## Skills - Apple: Swift (deepest expertise), SwiftUI (deepest expertise), The Composable Architecture (TCA) (deepest expertise), UIKit (deepest expertise), Swift Concurrency (deepest expertise), RxSwift (deepest expertise), Combine, Objective-C, Core Data, SwiftData (familiar), Instruments, App Store release automation (deepest expertise) - Backend & Services: TypeScript on Node (deepest expertise), Hono, Fastify, Vapor (Swift) (deepest expertise), Go, API design (REST and typed contracts) (deepest expertise), PostgreSQL, PostGIS, SQLite, Redis, WebSockets, Background workers - Web & Frontend: TypeScript (deepest expertise), React, Next.js, Vite, HTML / CSS - AI & Developer Tools: Effect (TypeScript), MCP servers, LLM integrations, On-device models (Foundation Models), CLI tooling (deepest expertise) - Platform & Delivery: Docker, Caddy, systemd, GitHub Actions, Git (deepest expertise), Xcode (deepest expertise) - Languages: Swift (deepest expertise), TypeScript (deepest expertise), Go, Python, Objective-C, Ruby (Rails) (familiar) - Design: Figma (familiar), Photoshop, Illustrator ## Education - BS, Computer Science, University of South Florida, 2013.
