Carson Szeder

Software engineer & founder.

I build real products for real users: prediction models, market infrastructure, and AI agents that run in production 24/7. Featured in WIRED for applying AI to sports betting.

Core expertise in agentic systems — the RAG pipelines, knowledge graphs, and open-source model stacks that make AI agents actually work in production.

Founder & Lead Software Engineer

monster.bet  ·  Mar 2024 — Present

  • Built the business from zero to one — architecture, product, data, and infrastructure — operating as founding engineer on every layer.
  • Designed and shipped a production Rust API (70+ endpoints, WebSocket streaming) and the Next.js / React customer app (270+ components, typed clients, real-time charts, Ethereum & Solana wallet support).
  • Built a real-time data platform covering 13 sports, 50+ sportsbooks, and prediction markets (Polymarket, Kalshi, Novig, ProphetX) — 100+ continuously running services collecting odds, results, and order-book data around the clock.
  • Developed pricing and prediction models for moneylines, spreads, totals, player props, DFS, and arbitrage — removing bookmaker margin and modeling exchange liquidity.
  • Built MonsterGPT, an AI betting copilot combining internal projections and live market data with retrieval-augmented web research — answering questions and surfacing bets through tool calls, not static prompts.
  • Shipped low-latency HFT execution in Rust: Kalshi parlay RFQ market-making with live order-book rechecks, exposure limits, and full audit trails — plus a Polymarket pipeline that provisions user wallets, syncs allowances, and executes and reconciles orders with real-time risk checks.

Kalshi RFQ Market Maker

High-frequency, low-latency Rust service that prices multi-leg parlay RFQs from live order books — rechecks book state pre-trade, models fees and slippage, caps exposure, prevents duplicate orders race-free, and submits signed quotes with full audit logging.

AI Content Agents

Agentic content pipeline — agents research competitors and audience trends, draft hooks and scripts, and generate image and video creative through Higgsfield MCP. Automated Meta Ads upload, review, and publishing; Airbyte pipelines land performance data into a self-hosted ClickHouse warehouse.

05 — Off the field

Former college baseball player

Left-handed pitcher at Folsom Lake College — competed in two California State Championships and took the win in a championship final. Also once ranked among the top 1,000 Fortnite players in the US.

I'm intensely competitive, and I like building products that hold up under real use.
