Founder
Sergiy Sanin
Twenty years building software, sixteen of them in algorithmic trading. Nine years of exchange connectivity, order routing and low-latency execution infrastructure at Credit Suisse, Standard Chartered and Tower Research; four years owning the core execution system at a Singapore crypto prop and market-making firm.
Since 2025, market-making on own capital under Delta Tech Consulting FZ-LLC — research, execution engines, risk and live operations, end to end. The measurement discipline that comes with running a book you own is the reason the research on this site reports the results that went against it as readily as the ones that did not.

Published
Working paper — RL over a calibrated market-making baseline learns a constant, not a policy. A pre-registered experiment on my own market maker in which every discriminating prediction failed, and folding each policy’s mean action into a single constant then recovered 132% of the trained policy’s edge and beat it in fourteen runs of fifteen. Roughly 71% of the measured improvement is accounted for by the policy simply trading less. The paper also withdraws a conclusion from earlier work of mine that failed to replicate, and lists ten defects found in my own code.
SSRN · data and verifier — over 300 assertions, non-zero exit on any disagreement.
Shorter measurement notes — cross-venue latency, markout against rebate, simulator fidelity, sample-size discipline and the economics of retail market making — are collected under research.
