Trading-System Evidence, Reliability & QA Reviews

I help algorithmic-trading and fintech teams find unsupported confidence before capital or production connectivity is involved. I review one sanitized architecture, repository slice, strategy specification, or completed backtest claim and turn it into an evidence-cited authority, data, and failure-path map; prioritized findings; and a practical remediation sequence.

My focus includes deterministic controls, duplicate or stale events, restart behavior and ambiguous outcomes, and realistic fees, spread, slippage, filters, rounding, and capacity assumptions. I work only from buyer-authorized, secrets-removed materials.

I do not request exchange credentials, private keys, wallets, order control, live funds, or production connectivity. I do not design strategies, give investment advice, certify security or compliance, or promise profitability.

Work Terms

Typical delivery is 24–48 hours after exact written scope, complete sanitized intake, and the full agreed amount is visible in Guru SafePay under the accepted Agreement.

Default first-stage scope is one legal entity and one buyer-authorized, secrets-removed package containing one supplied architecture, repository slice, strategy specification, or completed backtest claim. I deliver one authority/data/evidence/failure-path map, up to 10 prioritized findings with source or reproduction references, one compact remediation sequence, and one 30-minute handoff or written clarification round.

Please remove credentials, private keys, personal data, production secrets, and account identifiers before sharing materials. I do not need exchange, broker, cloud, repository, production, or payment-account connectivity. Missing evidence remains explicitly unknown.

Anything beyond the agreed first-stage scope requires a separate Agreement and SafePay funding. No strategy design, investment advice, security/compliance certification, live order placement, capital movement, or profitability guarantee.
