Senior Backend Developer (Node.js / PostgreSQL / Web3)

We’re building an analytics platform that aggregates data from prediction market platforms (Polymarket, Limitless, Kalshi).

Essentially, it’s a “screener for events” — users can view top trending events, betting volumes, trends, and real-time activity of major wallets.

MVP: the platform will place bets via APIs on Polymarket, Kalshi, and Limitless, and include AI-powered analytics tools.

In terms of design and interface logic, the platform will resemble Axiom, but without trading functionality.

Tech stack:

Next.js + Vercel — frontend

Node.js worker — data aggregation (Subgraph / API / WebSocket)

PostgreSQL / TimescaleDB — data storage

Redis — caching

We’re looking for a full-stack developer or a small team capable of quickly building a stable prototype.
