Andy Barnes

Senior finance analyst and Python builder focused on tech FP&A systems and AI workflow automation.

I pair FP&A judgment with working software: variance commentary, finance-data workflows, AI-tool integrations, and small merged fixes in public codebases maintainers recognize.

Selected public work includes FP&A automation, OpenBB and qlib finance tooling, merged PRs in OpenAI, Microsoft, Google Workspace, CPython, rust-lightning, x402 Foundation, Mesh-LLM, and OpenViking repositories, plus live product work around Bitcoin fee intelligence.

Role Direction

Direction	Relevant proof
Tech FP&A manager track	Variance Memo, Finance Dashboard write-up, OpenBB PRs, qlib-options, variance-commentary workflows.
AI workflow automation	Google Workspace CLI, google_workspace_mcp, bitcoin-mcp, OpenViking, mesh-llm, MCP/x402 operator work.
Finance-focused engineering	Python, SQL/SQLite, Streamlit, FastAPI, finance parsers, tested data-intake workflows.

Who This Work Serves

Audience	Relevant proof
Finance and FP&A teams	Variance Memo, Finance Dashboard write-up, OpenBB PRs, qlib-options.
AI tool maintainers and operators	OpenAI privacy-filter, Microsoft VibeVoice, mesh-llm, OpenViking.
Workspace and developer-tool users	Google Workspace CLI, google_workspace_mcp, CPython docs.
Protocol and payment operators	Satoshi API, bitcoin-mcp, x402 operator work, rust-lightning.

Flagship Work

Artifact	Proof	Why it matters
OpenAI / Microsoft / Google Workspace PRs	Merged fixes in openai/privacy-filter, microsoft/VibeVoice, and googleworkspace/cli.	Useful to AI research tooling, speech-model demos, and Workspace admin/developer workflows.
OpenBB contributions	Merged finance-platform parser cleanup and CLI tests.	Finance tooling credibility for analysts, developers, and tech FP&A teams.
Satoshi API	Bitcoin fee intelligence API, live at bitcoinsapi.com, with x402 pay-per-call support.	Turns raw node and mempool data into send/wait decisions that save sats and support paid API distribution.
bitcoin-mcp	49-tool Bitcoin MCP server, 126 tests, PyPI install, zero-config agent setup.	AI workflow automation proof: agents can call financial/protocol context through a tested tool layer.
AgentOps Ledger	Public AgentOps build with hosted demo, release, architecture diagram, Splunk HEC proof, launch page, and case study.	Makes agent tool calls, approvals, retries, errors, x402 payments, and final outcomes inspectable as run evidence.
x402 operator work	Merged x402 Foundation test coverage plus local self-hosted facilitator, SIWX, and payable MCP proofs.	Shows protocol work from both sides: upstream maintainability and payment-flow demos.
mesh-llm contributions	Merged security primitives, model-size health timeout, and capacity-label fixes.	Practical distributed inference fixes in a fast-moving Rust AI infrastructure project.
OpenViking contributions	Merged Windows PID-lock and console-input reliability fixes.	Cross-platform agent context infrastructure work with small, testable patches.
qlib-options	qlib-compatible options snapshot and factor pipeline with 25 focused tests.	Bridges finance workflow needs with reusable quant research tooling.

Contribution Pattern

I usually contribute where I can reproduce the problem locally and leave behind a cleaner test boundary: FP&A automation, AI workflow tooling, finance platforms, Bitcoin and Lightning libraries, x402, MCP servers, and Python ecosystem projects.

Recent merged examples:

• OpenAI privacy-filter
• Microsoft VibeVoice
• Google Workspace CLI
• OpenBB
• rust-lightning
• CPython
