Before the code, I trained in accounting and business organization — that's part of why I still think in posting flows and cost centers before I think in code, and part of why I keep pushing BC into places Microsoft didn't design it to run.

• 🔨 Building — test coverage and a watch mode for AL Runner (v2.3), and tightening up the BCQF methodology behind my code reviews
• 🌱 Exploring — grounding AI coding agents in real BC source with bc-code-atlas, an MCP server for AL dependency and implementation lookups
• 💬 Ask me about — running BC on Linux, fast AL test pipelines, or static analysis for AL

Run the unmodified BC service tier on Linux via a .NET startup hook that redirects Win32 P/Invokes, stubs HttpSys → Kestrel, and patches ~20 Windows-only runtime assumptions — all at boot, without touching a single Microsoft binary.

git clone https://github.com/StefanMaron/MsDyn365Bc.On.Linux
cd MsDyn365Bc.On.Linux && docker compose up -d --wait
# BC is live in ~5 min. No Windows. No VM.

Run AL unit tests without a BC service tier, Docker, or SQL Server. Transpiles your AL to C# via the BC compiler's public API, rewrites BC runtime types to in-memory mocks with Roslyn, and executes test codeunits directly — once dependencies are downloaded and the app is compiled, each test run itself takes milliseconds.

dotnet tool install --global MSDyn365BC.AL.Runner
al-runner ./src ./test
# first run downloads dependencies and compiles — later runs are near-instant

Pull Request
  │
  ├─ al-runner          (seconds)  — catches AL logic bugs fast
  └─ Full BC pipeline   (45+ min)  — full fidelity, only when needed

A queryable window into BC's AL source and official docs — semantic search, a structural call graph, and dependency lookups behind one MCP endpoint. Point a coding agent at it and ask where BC validates a sales order before posting, or what subscribes to a given event, and get an answer grounded in Microsoft's actual base-application source, not a guess from training data.

Project	What it does	Stars
MSDyn365BC.Sandbox.Code.History	Builds on sandbox artifacts instead of on-prem, so it picks up hotfixes and updates daily
MSDyn365BC.Code.History	The original on-prem source history, updated monthly

I do independent Business Central consulting for BC partners and ISVs across Europe — see stefanmaronconsulting.com for details.

• Extension code review — 5–10 days, with an optional compliance report against ISO/IEC 5055
• Custom AL development & third-party integrations — banking, e-commerce, field service, business automation — project or retainer, EU-wide
• Developer training — AL fundamentals, upgrade-safe patterns, AI-assisted workflows — half-day or full-day, for teams of 2–10
• DevOps & tooling — GitHub Actions / AL-Go setup, static analysis wired into CI as a quality gate

I also wrote the Business Central Quality Framework (BCQF), a versioned extension of ISO/IEC 5055:2021 for AL and Business Central, and I'm the original author of LinterCop, the first community-driven AL static analyzer (now part of the broader ALCops initiative).

Public GitHub activity — my own repos and contributions to others, refreshed daily. Commit counts run through a lot of AI-assisted sessions these days, so treat them as an activity signal, not a productivity one.
