Finance analyst (FP&A) building Python tools for financial data review and auditable agent workflows. My open-source work spans AI infrastructure, Bitcoin and Lightning payments, and the reliability bugs that show up after a restart or halfway through a message.
| Project | Problem it addresses | What you can try |
|---|---|---|
| Finance File Triage | Turn messy CSV/XLSX data into row-linked review drafts across 4 finance data families: FP&A variance, brokerage positions, cash transactions, and invoices. | Browser app; files stay on your device. |
| Agent Payment Ledger | Inspect what an agent attempted, paid for, or was blocked from doing across 3 seeded runs and 6 event types. | Static walkthrough, dashboard screenshot, and case study. |
| Wallet Policy Kit | Check coin-pool separation and restart behavior with 27 conformance cases. | Downloadable Python research kit with reproducible fixtures. |
46 external public PRs merged across 37 repositories, with merges in each of the 8 weeks from August 10 to October 4, 2026. Weekly contribution log.
| Project | Change | What was hard about it |
|---|---|---|
| OpenAI Python SDK | Publicly export type_to_response_format_param |
Callers can use openai.lib instead of private parsing modules. Resolves an upstream feature request; merged October 2, 2026. |
| NSA Ghidra | PyGhidra: keep bean properties out of script globals iteration | With no program open, JPype bean properties like firstFunction throw on read, so iterating script globals (and interpreter completion) broke. Took a second round after maintainer review to cover the no-program case. |
| vLLM | ROCm fixes, incl. a cu_seqlens_q off-by-one in AITER speculative decode (#39120) and config registration before tokenizer init (#40299) |
Six merged. Most were found by reading AMD kernel paths against the backend they were supposed to match. |
| Mesh-LLM | Owner keystore and signed+encrypted message primitives (#156), then a run of Windows fixes | Nine merged in a fast-moving Rust distributed-inference project; I mostly own Windows breakage there now. |
| rust-lightning | Expose current dust exposure in ChannelDetails |
Operators can now watch how close a channel is to its dust limit, counting commitment fees as well as dust HTLCs. |
| rust-bitcoin | From<Infallible> for 31 public error types |
Small idea, wide surface: units, primitives and consensus_encoding all had to line up so generic ? code compiles. |
| HoloViz Panel | Fix nested Plotly array loss across clients | Reusing a figure dropped nested array data for the second client. Binary serialization was mutating containers that shallow copies still shared. |
| LiveKit Agents | Forward provider events through session restarts | Provider-specific realtime events were lost every time the fallback wrapper swapped its child session. |
| ordinals/ord | Warn when exporting addresses without the address index | Replaced a hard error with a warning, following maintainer direction from an earlier PR. |
- Bitcoin Core #36190: tests that the
bitcoinwrapper reports child exit status correctly on Windows. Code-review ACKed; waiting on a dependency. - x402 #1873: request-bound Lightning upfront payments for the Python SDK, with replay protection that holds across restarts.
- NEAR near-sdk-rs #1638: ABI generation failed to link on Windows MSVC hosts for about two years.
- x402 + Lightning in Python. Payment verification, settlement and replay handling. Notes: x402-work.md.
- Bitcoin research. What a private-payment wallet has to keep so it can still recover and spend after a service disappears. Reproducible experiments and their limits: bitcoin-research.
- Wallet policy kit. Try the Python-only checks for coin-pool separation, or reproduce payments and saved-wallet restarts on regtest. Report a trial or wallet use case.
- Mesh-LLM on Windows.
- bitcoin-mcp: MCP server that gives agents Bitcoin node, mempool and fee context. 50 tools, 180 tests.
- Satoshi API: self-hostable fee-intelligence API behind bitcoin-mcp, with optional x402 payments. The public hosted instance is paused.
- qlib-options: options snapshot and factor pipeline for Microsoft qlib.
The day job is FP&A. The overlap shows up in OpenBB and qlib work, variance-commentary tooling, and a lot of Python that turns messy finance data into something a person can sign off on. Case studies.
