Core Uptime
FAST, RESILIENT & PREDICTABLE SOFTWARE
I specialize in modern backend development with .NET 8 and distributed systems, turning complex domain requirements into clean, testable architecture.
Performance First
Redis caching, zero allocations, and tuned queries keep p95 latency under strict thresholds.
Clean Architecture
CQRS, MediatR, and domain-driven separation make systems maintainable and extensible.
Production AI
Integrating Azure Speech, OpenAI embeddings, and async pipelines for production-grade intelligence.
Production Systems Built for Real Scale
Battle-tested backend architectures, low-latency APIs, and AI integrations.
EnglishAI
Adaptive English platform with speech assessment, placement testing and real-time pronunciation scoring.
KitobdagiMen
Social book reading platform with Telegram Mini App auth, algorithmic discovery feed and live quotes.
TypingWar
Multiplayer typing duel engine with sub-50ms synchronization, anti-cheat validation and live lobbies.
