113 USDSummary
Title: Python Developer Needed to Build Automated Event Trading Bot (Prediction Markets + API)
Overview:
I'm hiring a Python developer to build an automated system that pulls live event data from a public API, reads prediction market prices from Kalshi, runs a probability model I provide, and executes paper trades (and later real trades once validated).
This is an implementation project, not a research project. The strategy logic and model specification will be provided after signing an NDA.
Your responsibilities:
- Integrate with a public event API (details after NDA)
- Integrate with Kalshi's API (market data + order placement)
- Build scripts that:
• Pull live event data
• Pull market prices
• Compare data with model output
• Simulate trades based on rules I provide
• Log everything to CSV or database
- Later add:
• Stake live trading mode
• Basic analytics tools to evaluate model performance
Required skills:
- Strong Python experience
- REST/JSON API integration
- Automation / scripting experience
- Data handling and logging
- Bonus: experience with trading bots, events APIs, or prediction markets
Project duration:
6–8 weeks
What I will provide:
- Full model specification after NDA
- API keys
- Clear trade rules and logic
- Ongoing feedback and iteration direction
Important:
The specific sport and full strategy details will only be disclosed privately after NDA is signed.
If you reach the interview stage, I will ask for a short Python function that calls a public JSON API and parses a few fields. This helps ensure a good technical fit.

Good day,
I am ready to take on your project. I have extensive experience with Python and task automation. I will be able to integrate public event APIs, work with the Kalshi API, and create the necessary scripts for data retrieval, comparison, and trade simulation.
My rate is $16 per hour. I am ready to start working when I receive additional details about the project and responsibilities.

Hello!
My name is Semen, I am the manager of the company Wanord. We specialize in Python development, integration with exchange/financial APIs, building trading bots, data pipelines, and analytical dashboards.
📌 What is needed:
Create an automated Python system that:
receives real-time event data from a public JSON API;
reads forecast market prices from Kalshi (quotes, order book);
…
runs this data through the probability model you provide;
executes paper trades according to specified rules with full logging;
then transitions to live trading mode and obtains basic performance analysis tools for the strategy.
The technical specification/task description is clear — we see this as a project implementation with clear stages.
🔧 What we will do:
Integration with the public event API
We will connect to the JSON API (authorization, rate limits, retries), set up a stable real-time event feed.
Integration with the Kalshi API
We will obtain quotes and market data (prices, volumes, contract statuses) + prepare a layer for placing orders (initially in “dry-run” mode).
Trading script / strategy core
Obtaining current event data.
Obtaining market prices from Kalshi.
Comparing with the output of your probability model.
Making decisions according to the rules you provide (entry/exit, position size, risk limits).
Simulating trades (paper trading) with a complete history.
Logging and data storage
We will implement detailed logging: trades, signals, strategy state, API errors. Saving in CSV and/or database (e.g., PostgreSQL/SQLite) for further analysis.
Live trading mode (later stage)
After validating the results of paper trading, we will add a live mode with protection against incorrect signals, risk limits, and fallback scenarios.
Performance analytics
We will implement basic metrics: PnL, win rate, max drawdown, Sharpe-like ratios, periods where the model performs best/worst. We can add a simple web or notebook interface for reviewing results.
NDA and technical test
We are ready to work under an NDA and complete a small test (a function that pulls data from a public JSON API and parses fields) to confirm technical proficiency.
💼 We have experience:
Python scripts for high load, trading bots, integrations with REST/JSON APIs, processing financial data, logging, and building analytics (ETL pipelines, client dashboards, SaaS platforms).
💰 Budget: from $5000 to $9000 (fixed price with phased payments)
⏱️ Timeline: 6–8 weeks, broken down into stages: integrations → paper trading → live mode + analytics.
