Проекты
Ritma — SaaS-Style Notification Backend
Rebuilt an MVP into a modular backend platform with repository pattern, service layer, isolated adapters, and background workers. Implemented timezone-safe event modeling, notification orchestration, partner-aware flows, custom messaging logic, recipient preferences, and phase-based delivery rules. Designed idempotent notification handling to prevent duplicate events and maintain consistency across async workflows.
SMS Verification & Anti-Bot Bypass System
Engineered a browser automation solution for protected registration flows using SeleniumBase UC Mode and custom Chrome extensions. Handled proxy authentication, CAPTCHA-solving services, SMS verification APIs, and React SPA input events. Improved automation reliability by emulating realistic browser behavior and debugging request/session issues.
Microsoft Sentinel Threat Hunting Notebooks
Built Python analytics components for Microsoft Sentinel XDR threat hunting workflows in Azure ML. Implemented cross-domain correlation, KQL utilities, threat intelligence enrichment, and anomaly-detection support tooling.
