Quantitative Systems Engineer

“I build quantitative systems for businesses who can’t afford to be wrong.”

Most businesses don’t know how to extract full value from their data — they either hire a team with no clear direction or throw money at tools that never drive decisions.

That’s why I launched NúmerosDon Data Solutions. Whether as a project partner, a retained expert, or embedded in your team, my goal is simple: build the quantitative systems that will increase your profit margins.

Let me take ownership of your data challenges so you can take ownership of the results.

How I Increase Your P&L

I engineer the entire quantitative pipeline, from raw data ingestion to production-ready systems.

1
Revenue Protection
The Audit
Find the hidden leaks costing you margin before they hit your P&L Know exactly when your model is lying to you — and how to fix it Walk away with a prioritised engineering plan, not a slide deck
Outcome
A prioritised map to recover lost margin.

System Engineering
The Build
Replace fragmented spreadsheets with hardened, automated pipelines Get decision-ready output tuned to your specific risk appetite Own everything — full runbooks, full documentation, zero lock-in
Outcome
Decision-ready systems with zero manual lag.

Performance Monitoring
The Maintenance
Get alerted the moment your environment shifts — before it costs you Systems that retrain and evolve automatically as the data moves An expert on retainer for architecture reviews when the stakes are high
Outcome
A system that doesn’t break when you turn your back.

Specialist Engagements
Focused Execution
A specific problem requiring specific expertise — no templates Custom scrapers, architecture reviews, or a second opinion on a critical trade Typical engagements: 1–2 weeks
Outcome
The exact answer you need, fast.
Inquire about availability
DECISION-GRADE
Calibrated probabilities + proper scoring rules. No guesses.
PRODUCTION-HARDENED
Automated pipelines + reproducible runs built to survive high-stakes punishment.
FULL OWNERSHIP
100% handover. Monitoring, drift checks, and documentation. No black boxes.
Async-friendly. Minimal meetings. Maximum shipping.

The NúmerosDon Delivery Process

A structured framework designed for remote execution and immediate impact.

1
Strategic Diagnosis (30 min)
We define the technical bottleneck, data constraints, and the specific cost of being wrong. I don’t start until we both agree on what “winning” looks like.
Goal: Absolute clarity on the objective. Result: A scoped plan with no fluff.
2
High-Velocity Build
Aggressive sprints with minimal overhead. Weekly updates, a mid-way demo, and full focus on shipping production-grade code.
Goal: Decision-ready output, fast. Result: A working system you can run and trust.
3
System Hardening
Delivery isn’t a zip file. You get the Fix Map, runbooks, and a monitoring plan to ensure the system survives reality once I’m gone.
Goal: 100% internal ownership. Result: A system that keeps paying you back.
