About this Gig
Hello! My name is Filipe.
I design and develop high-performance forecasting agents for markets like Polymarket, Kalshi, and PredictIt, focused on real probability, statistical calibration, and data-driven decision-making.
With experience in quantitative engineering and trading systems, I build agents that go beyond simple models they are complete pipelines for forecasting, analysis, and continuous probability updates.
What I can develop for you:
- Probabilistic forecasting agents for real-world events (macro, politics, crypto, economics).
- Calibrated statistical models (Bayesian, regression,ensembles).
- Real-time data scraping and ingestion systems.
- Feature pipelines and automated signal generation.
- Efficient market modeling and edge detection.
- Forecast backtesting with scoring (Brier Score, Log Loss, calibration curves).
- Multi-model systems (consensus + dynamic weighting).
- Integration with Polymarket, Kalshi, and PredictIt APIs.
- Continuous performance monitoring and model drift detection.
- Infrastructure for autonomous forecasting agents.
If you want to turn data into actionable probability, I can build that for you.

FAQ
How does the service work?
You describe the type of event or market. I design the agent, define the architecture, and develop the full forecasting and evaluation system.
Do the models actually update themselves?
Yes. I can build systems with continuous data updates and automatic or semi-automatic retraining.
Is this only for crypto or politics?
No. It works for any event with structurable data and implicit probability.
Do you provide performance metrics?
Yes. This includes calibration, forecast error, Brier Score, log loss, and historical accuracy analysis.
Why talk before ordering?
To define the event type, update frequency, and the ideal agent architecture.
