1. High-Concurrency Server Engine (Arise Core Engine)
Domain: Distributed Systems & Core Backend Engineering (C++ 20 / Lua JIT)
Engineered a high-performance backend architecture capable of sustaining 2,000+ concurrent active connections with sub-10ms tick latency. Highlights include:
- Custom low-overhead memory pools preventing fragmentation and memory leaks.
- Lua script runtime engine supporting live hot-reloading with zero downtime.
- Optimized binary network protocol reducing bandwidth overhead by over 40%.
2. Cryptographic Payment Bridge & Webhook Hub
Domain: Financial Integration & API Security (PHP 8.2 / HMAC SHA-256)
Designed and deployed a unified financial bridge connecting diverse gateways (Thawani for regional cards, Payssion for global methods, and automated crypto) into a single secure hub:
- Instant HMAC SHA-256 signature verification preventing replay and tampering attacks.
- Immutable audit logging with automated webhook callbacks for instant license provisioning.
- Resilient idempotency handling ensuring zero double-charging or lost transactions.
3. Dynamic Multilingual Engine & Formula Compiler
Domain: String Processing & UI Engineering
Engineered a localized string compilation subsystem capable of rendering dynamic tooltips across Arabic, English, and Russian, featuring real-time mathematical expression parsing and variable injection.
4. Database Indexing & Infrastructure Hardening
Domain: Performance Optimization (MSSQL / High Availability)
Re-architected and indexed multi-gigabyte transactional databases, reducing high-frequency query latency from seconds to sub-millisecond execution while securing network boundaries.
