Selected Work

Multi-Antivirus (MAV) architecture.
Multi-Antivirus (MAV) architecture. Event-driven scan pipeline across multiple datacenters (DC-1–DC-4): Socks proxy → shared-storage scanner pools (ESET, Kaspersky, Padvish, Dr.Web) and downloaders → per-engine work queues.
Global response time — p95 per country/city.
Global response time — p95 per country/city. Tail-latency tracking across 45+ cities in 28 countries (Tehran ~48 ms to worst-case ~4 s), the signal used to drive latency reductions.
Global latency heatmap.
Global latency heatmap. Geographic view of API response times feeding the same Python/FastAPI monitoring system.
Dependency health dashboard (proxy/API checker).
Dependency health dashboard (proxy/API checker). Pythonic checker monitoring critical external dependencies (payment, mail, auth providers) — response time, failure rate (1.59% shown), tunnel latency and HTTP status mix.
