Quantitative Development Built on Real-Money Experience

My quant development expertise comes from 8+ years of active market experience and a track record across high-stakes environments. Each role taught me critical skills I now apply to building robust algorithmic trading systems.

Available for Full-Time Quant Roles & Select Consulting Engagements
Interested in prop firms, systematic trading teams, and trading technology companies

How My Background Strengthens My Quant Development

Each career phase developed specific skills that make my trading systems more robust

2014–2017

Construction PM

Data Architecture

Managing construction projects taught me to design for failure modes and scale. I now apply this to trading infrastructure: planning for 3x load, calculating resource constraints, and building systems that don't collapse under volatility.

Quant Development Skill: Robust system architecture
Quant Development Skill: Capacity planning & cost optimization
2018–2022

Head of Trading & Quant Data Systems

Fintech Alca Group
8+ Years
Market Experience

Built and governed the firm's data infrastructure from scratch: real-time WebSocket ingestion, performance-critical pipelines with full auditability, and high-availability decision-support systems on PostgreSQL and TimescaleDB — for futures, FX, crypto, and equities.

Quant Development Skill: Real-time market data infrastructure
Quant Development Skill: Risk management & capital allocation
7+ YEARS BUILDING SYSTEMS • CURRENT

Quant Developer & Educator

DataWithJose · Self-employed

Productized proprietary trading algorithms end-to-end: API data ingestion → signal generation → automated execution with dynamic risk management. Custom bot solutions for private clients across futures, FX, crypto, and equities — engineered for high availability and observability.

Core Skills: Python, C# (NinjaScript), Pine Script, Docker
Specialization: Validation-first research → live execution

Bottom line: 8+ years of market experience building systems where failure isn't an option — from research to execution.

What Clients Really Say

Real feedback from funds, founders, and quant teams who've worked with me

"Jose designed a comprehensive data infrastructure that improved our patient-doctor matching process at GrowMyClinic. He integrated our CRM with call tracking systems, appointment scheduling platforms, and marketing attribution tools into a unified dashboard. Before his solution, we were losing potential patients due to poor follow-up tracking. Now we can see which marketing channels drive the highest-value appointments, track conversion rates by medical specialty, and automate follow-up sequences. Our patient conversion rate improved from 28% to 35%, and we saw a 15% increase in average appointment value. The real-time analytics helped us identify that our cardiology referrals had the highest lifetime value, allowing us to optimize our marketing spend accordingly."

Alpha Strategies Fund

"Jose developed a momentum strategy for us that combines technical indicators with alternative data sources. The system processes social sentiment and options flow data in real-time. His implementation of dynamic position sizing using Kelly Criterion was well thought out. We've seen decent returns with reasonable risk management."

Daniel Graham

TheTraderDaddy

"Jose developed a momentum-based trading algorithm that processes multiple crypto pairs with proper risk management. His implementation includes dynamic position sizing using Kelly Criterion, real-time risk monitoring with 3% max drawdown limits, and automated stop-loss mechanisms. The system has maintained consistent performance over 8 months with reasonable risk-adjusted returns. What impressed me most was his integration of social sentiment data from Twitter and Reddit APIs to enhance signal accuracy during volatile market conditions."

Unicorn.Academy

"Jose architected a streamlined MLOps pipeline using Python, PostgreSQL, and MLflow that improved our training platform. He implemented automated feature engineering pipelines that process our 2,500+ student interactions daily, built A/B testing frameworks for our course recommendation system, and created model monitoring with performance tracking. Our model deployment time went from 3 weeks to 3 days, and we achieved 15% improvement in course completion rates. His GDPR-compliant data processing framework was essential for our European students."

What I Build

Robust algorithmic trading systems — engineered from research to execution. Not just strategies: the full infrastructure that takes an idea from hypothesis to live trading with real capital.

Live-Tested | Walk-Forward Validated | Risk-Controlled

Mean Reversion OU Trading System

Ornstein-Uhlenbeck mean reversion strategy with ML-driven parameter optimization — taken from research to live trading with real capital. In trading, a strategy is only as good as the system executing it.

Research → Backtest → Execution

Research pipeline: Regime classification + OU parameter estimation on validated market data

Backtesting: Overfit-resistant validation with realistic execution modeling

Execution & risk: Automated trading with position sizing, stop-loss management, and drawdown controls

Monitoring: Performance analytics and risk dashboards watching every position in production

Key Features

ML parameter optimization
Real-time execution & risk management
Walk-Forward

Clean Data → Valid Backtests

Research & Backtesting Infrastructure

Backtests are only as good as the data behind them. I build market data pipelines and validation frameworks that make research trustworthy — and fast enough to iterate on ideas daily.

Python, PostgreSQL, Airflow
Reproducible research workflows
Data quality gates & validation
Real-Money Trading Systems

Live Execution & Risk Systems

Built end-to-end systems powering algorithmic trading with real capital. When your pipeline fails at market open, you lose money every second — that taught me to build systems that stay up.

WebSockets, Kafka, TimescaleDB
Low-latency market data ingestion
Production-tested with real capital

Why Work With Me?

I build trading systems where failure has real consequences:

Robustness First

Systems designed to survive the market — with failover, quality gates, and monitoring from day one

Research-to-Execution Focus

Ideas validated rigorously before a single dollar is at risk — then executed with discipline

Validation-First Perspective

8 years of active market experience — walk-forward, out-of-sample, and sensitivity testing before anything goes live

The difference: an attractive backtest is cheap. I build systems that stay honest when assumptions change — and survive live markets.

About Me

Quantitative Developer with 8 years of active market experience — focused on turning trading logic into systematic, validated, and executable systems, from research to live execution.

I spent four years in construction project management learning how systems fail under pressure. Then came the markets: from building a fintech group's trading data infrastructure from the ground up, to productizing my own algorithms and automating client strategies across futures, FX, crypto, and equities.

The pattern is clear: I've always worked where reliability isn't optional and every decision is backed by data. Construction taught me to design for failure modes. Trading taught me that validation is non-negotiable — a strategy is not robust simply because it produces an attractive backtest.

I specialize in quantitative research, backtesting workflows, and automated execution — testing strategies out-of-sample, with walk-forward validation, sensitivity analysis, realistic costs, and risk controls built in.
