Custom quantitative software, machine-learning, and data systems for financial firms. Built end to end, on your data, owned outright by you. For the workflows vendor platforms can't reach and the edges consulting won't ship.
Every serious firm carries the same gap: workflows too specific for off-the-shelf platforms, edges too proprietary for a consultancy. Data scattered across custodians and fund admins. Diligence that needs forensic depth. The work is automatable, but building it properly means standing up a full quant-engineering function, so it stays manual and your best people rekey data instead of making decisions.
Read an entire data room, cross-check management's claims against the source documents, cite every page. Months of work compressed into days, and it stands up to your IC.
Holdings across every custodian, bank, and asset class in one verified view. A multi-day reporting process turned into minutes, on a clean data layer your models can actually use.
Live engines that aggregate market, portfolio, and on-chain data into a single source of truth, with an analytical layer that answers questions instead of making you dig through tabs.
If it's financial, document-heavy, and done by hand today, it can be built. Scoped to your exact workflow. Not a generic platform you bend to fit.
Two buyers, one system. The CIO buys research and data; the COO, compliance officer, and controller buy the reporting and control layer underneath. This is that layer, built to the standard your auditor and examiner will hold it to.
The layer that removes the operational overhead constraining your mandate. Risk and regulatory reports in your required format, reconciled against every feed, audit trail on every number. What takes a team a week, produced on schedule, unattended.
Every output traces to the document it came from; every run is logged. Identity, permissions, and approved sources enforced in one place, built to stand up to compliance, audit, and an examiner.
Mutual NDA signed before the scoping sprint begins.
AWS, Azure, GCP, or on-prem. Your account, your VPC, your controls.
We never custody, host, or move your data into a vendor cloud.
Source code, infrastructure, and data are yours. No lock-in.
We run a systematic, market-neutral fund. To operate it, we built the Dark Matter Terminal: a live market-intelligence system spanning forensic accounting, an 18-method valuation ensemble, a live 13F reader, dark-pool tagging, and shipping-flow tracking, fronted by a conversational layer that answers any market question with cited research.
Built end to end, in-house. Not a slide deck: production infrastructure the fund trades on every day. Most firms put systems like this in a five-year plan. We run ours daily, and it's the proof of what we'll build for you.

A fixed-fee sprint to spec your workflow, data sources, and the build, with a working prototype on your real data. Fully credited if you proceed; if the spec isn't right, you walk with the work and owe nothing. You know exactly what you're getting before you commit.
Delivered in stages tied to working deliverables on your data. You don't pay past any milestone unless it's delivering exactly what was promised. Code review with your CTO, external auditor, or trusted advisor is welcomed. Encouraged, actually.
It runs in your environment, your controls, full audit trail. Source, infrastructure, and data are yours: no black box, no lock-in, no year-two ransom. Optional maintenance keeps it sharp as your needs evolve.
The same adversarial process that has killed more of my own strategies than it has kept, turned on your models, your backtests, your assumptions. What survives is what you deploy. Nothing reaches your book on trust alone.
Custom systems delivered end to end, on your data, the source owned outright. Scoped by a fixed-fee sprint and delivered milestone by milestone.
Fractional quant engineering for a CIO or PM: architecture, vendor assessment, technical review, and hands-on build. The capability of a senior hire, without the headcount.
Bring your analysts up on the systems and methods, taught from the same practitioner stack a live fund runs on. Hands-on or cohort-based.
A sceptical buyer's mental matrix, drawn explicitly. Pick the column that fits.
Every claim in the memo cites the filing it came from.
An analyst's spreadsheet nobody can audit six months later.
The system runs in your environment, every action logged.
Firm data sitting in a vendor's cloud you can't inspect.

I run Dark Matter, a systematic, market-neutral digital-asset fund, and built the market-intelligence system it trades on: data pipelines, research and forensic engines, execution, and a conversational layer that answers any market question with cited research.
Through Dark Matter R&D I build systems of that caliber for other firms, on their data, in their environment. You work directly with the person writing the code, not a junior or an account manager. The distinction that matters: the fund trades on these systems every session, so when a pipeline breaks or a backtest turns out to have been lying, it costs me money the same day. That is a materially different incentive from a consultancy whose deliverable ends at handoff, and it is why the work is built to survive a live book rather than a demo. If your team is doing by hand what well-built infrastructure should handle, I'd welcome the conversation.
A live trading desk. We know what survives an IC, an auditor, and a Monday open, because we ship to ourselves daily.
The person scoping your build writes the code and stands behind it. No juniors, no telephone, no offshoring.
Source-traceable output, cited to the document. Built to stand up to an IC and an auditor, not to impress in a demo.
Runs under your controls, full audit trail. Source and data yours outright, no positions ever touched.
If your IC, CTO, or compliance officer would ask it, it's probably below.
Your environment: AWS, Azure, GCP, or on-prem, in your account and VPC. We never hold or move your data into a vendor cloud. Mutual NDA on every engagement, signed before the scoping sprint.
You have the full source and documentation in your repo from day one. A qualified engineer can pick up where I left off. No black-box hosting, no proprietary runtime, no lock-in.
No, it runs unattended. For changes, retain me monthly, hand it to your team, or hire a freelance engineer. Most pick the retainer because it's cheaper than one developer day.
Off-the-shelf platforms force your workflow to fit their schema, charge in perpetuity, and don't extend to the messy edges: your bespoke statements, your custom diligence, your specific monitoring. If a platform fits, use it. If it doesn't, the manual work isn't going away, and that's where I come in.
I'm not packaging a generic LLM behind a chatbot. What I'd build for you is purpose-built infrastructure where AI is one layer over a deterministic, source-traceable engine. Every claim cites the underlying document or data point, and the output stands up to an investment committee.
Scoping sprints are fixed-fee and fully credited to the build. Builds scope from single-workflow systems through enterprise-scale infrastructure. The sprint produces a written spec with a fixed quote, so you decide on a known number, not an open meter.
Python for data, machine-learning, and quantitative work; C++ / Rust in performance-critical paths (execution, tick-level signals); TypeScript / React for any UI. The right tool for the job, every choice documented so your team or a successor can read the code.
Yes. Mutual NDAs, MSAs, your DPA. I welcome code review by your CTO, an external auditor, or a trusted advisor. I'd rather you verify it than take my word for it.
Bring one process. The one your best people lose a day a week to and everyone agrees should be automated: the reconciliation, the diligence read, the reporting pack, the data pull nobody trusts. Tell me what it costs you in hours and where it breaks.
You get a working diagnostic: whether it should be built, what it would take, and where the hard parts are. If a platform already does this well, I'll tell you that instead. Direct, no slide deck.
