Vanja Sretenovic Vectorix Polymarket trading bot
VECTORIX     SOFTWARE ENGINEER
POLYMARKET TRADING BOT  ·  CRYPTO TRADING  ·  TOKEN LAUNCH
NOVI SAD,      SERBIA

Live portfolio

Vanja Sretenovic builds a Polymarket trading bot, betting and market desks, Solana token-launch / memecoin pool tooling, and crypto trading automation. Search: Polymarket, trading bot, prediction market, token, liquidity pool.

ABOUT

Main line of work is a Polymarket trading bot and the stack around it — market discovery, live CLOB books, model probability against the quote, rule-based entries, and execution that cuts out when the risk caps hit.

No sitting on the book clicking fills. The bot watches the tape, picks a size, and stands down when the rules fire.

Four years at ZESIUM Mobile (2020–2024) on backends, APIs, and realtime systems. Since 2024 the work has been independent: Web3, Rust, and prediction-market automation.

FOCUS

PREDICTION MARKETS

  • Polymarket trading bot — live books, implied vs modeled probability
  • Condition engine and automated execution
  • Kill-switches and position limits

TRADING AUTOMATION

  • Trading bots for Polymarket and crypto books
  • Strategy engines (paper and live), Robinhood-style tickets
  • Expected value, sizing, and risk

BLOCKCHAIN WEB3

  • Token launch, memecoin, liquidity pools
  • Wallets, swaps, on-chain data
  • Casino-style / prediction games on-chain

AI IN PRODUCT

  • OpenAI APIs inside real workflows
  • LLM tooling around trading and ops
  • Agents as software, not demos

STACK

LANGUAGES Rust Python TypeScript JavaScript
MARKETS Polymarket / betting Token launch / pools Solana memecoin Crypto markets
SYSTEMS WebSockets Docker GitHub Actions Linux

SELECTED WORK

PROJECT WHAT IT IS
Polymarket trading bot Flagship Polymarket trading bot: TypeScript + Python engines, live CLOB, strategy boards, paper fills, hard risk caps. Prediction-market microstructure — not a generic exchange bot.
Polymarket desk Live operator terminal: 24h movers, live tape, watchlists, consensus screens, intent-only tickets. Built for trading the market, not browsing it.
Pump.fun launchpad Full Solana stack in one repo: Anchor bonding-curve program, Next.js launch UI, indexer API, Raydium graduate path.
Solana arbitrage bot Rust pool graph + on-chain hop program. Size the cycle across Serum, Orca, Saber, Aldrin, Mercurial, then submit while the quote still covers fees.
CrossYield Cross-chain RWA yield path: Ethereum deposit, Wormhole VAA, Solana vault shares, harvest loop.
