Specification
We are looking for a developer to finish and stabilize an existing Kalshi trading bot (~60% complete) built in TypeScript.
This is not a MetaTrader EA. The system interacts with the Kalshi API and requires strong understanding of execution logic, order handling, and state management.
Scope of Work:
- Review and understand existing TypeScript codebase
- Complete missing functionality
- Fix execution issues (order placement, retries, state sync)
- Handle edge cases (partial fills, API errors, timeouts)
- Improve reliability and stability
- Implement proper logging and trade tracking
Key Requirement (Important):
Experience with API-based trading systems (not just MT4/MT5 EAs)
You MUST have:
- Node.js / TypeScript experience
- Experience working with trading APIs
- Understanding of order lifecycle (placed → partial → filled → cancelled)
- Experience debugging real-time systems
Do NOT apply if:
You only build MT4/MT5 indicators or EAs without API integration
You have no experience handling order state or execution logic
To Apply, answer these:
- What trading APIs have you worked with?
- Have you handled partial fills and order state tracking? Explain briefly
- Describe how you prevent duplicate orders during API retries
- Share 1 relevant project (GitHub or description)
- Your experience with TypeScript
Availability to start
Goal:
Deliver a stable, reliable trading bot that runs without execution errors.
