Olaaia builds software. Clients run software on their own brokerage accounts with their own keys. Olaaia does not custody funds, does not trade client accounts, and does not provide investment advice. Trading involves risk of loss.

Why us

Built on institutional background, delivered by the founder.

Institutional background

Built OMS and HFT arbitrage systems with FIX/ITCH connectivity for South American banks before going independent.

Founder-only delivery

Every line of code, every backtest, every deploy is mine. No offshore subcontracting.

Teaching-grade code

I teach Algorithms & Data Structures and Operating Systems at CAECE University — code you can read and maintain.

Risk-honest engineering

No 'guaranteed returns'. Every deliverable ships with backtests, walk-forward results, drawdown profiles and a regression test suite.

FAQ

Questions before we talk?

Do you guarantee returns?
No, and any developer who does is a red flag. I guarantee engineering quality, walk-forward validated backtests, and a clean handover. Market performance is your responsibility.
Who owns the source code?
You do. 100%, from day one. Source lives in a private GitHub repo; on final payment the repo transfers to you.
Do you take a cut of profits?
No. Fixed scope, fixed price. Profit-share only on multi-quarter institutional engagements with mutual due diligence.
What brokers and venues do you work with?
Interactive Brokers (ib_insync), Binance / OKX / Bybit / Hyperliquid (REST + WebSocket), MetaTrader 5, NinjaTrader 8, Rithmic, plus FIX 4.2/4.4 for institutional venues.
NDAs?
Standard. Mutual NDA before any code or proprietary strategy is shared.
Do you trade my account?
No. I build the system; you run it on your account, your keys, your risk.
Where are you based?
Mar del Plata, Argentina (UTC-3). Synchronous with US / LATAM / EU; async with APAC.
How fast can you start?
Discovery call within 48 hours of inquiry. Build start typically 1–2 weeks after scope sign-off.
