Experience
Evaluation-Harness Forensic Audit
KriptoFarsi (own platform) 2026 - 2026
Istanbul. Audited an implausibly strong performance result and traced the headline +310-percentage-point figure to a sign-flip caused by an abs() call in the accounting code; also fixed a phantom-entry bug corrupting the recorded trade set. Rebuilt the measurement layer as a correction-aware historical replay engine, recovering an honest signed result of +54.45pp that degraded to roughly +1.8% once realistic execution costs were modelled. Applied statistical testing to 700+ recorded signals (t-statistic ~1.0; bootstrap CIs containing zero), concluded the strategy was indistinguishable from noise, and retired the operation rather than publish an inflated result.
Systems Administrator
Alien Games (Online Gaming Platform) 2013 - 2020
Owned production infrastructure for a live online game (servers, domains, online services, public APIs), responsible for uptime, monitoring, and incident response under real user traffic. Led perimeter security and DDoS mitigation across Cloudflare, Incapsula, and Voxility. Managed cloud and vendor operations across Google Cloud, DigitalOcean, Namecheap, and third-party SaaS, including B2B vendor negotiation, procurement, and cost accounting. Performed game testing and pre-release QA: reproducing defects, isolating root causes, and reporting actionable findings.
