My design philosophy is built on **high availability**, **strict schema validation**, and **eventual consistency where appropriate**. - 🔭 Currently building: **Distributed event ledger** handling 100k+ sustained events/sec. - ⚙️ Deep-diving: **eBPF-based networking filters and kernel-level performance tuning**. - 🛠️ Infrastructure: **Postgres replication, Redis cluster caching, Kafka stream processing**. - 💬 Ask me about: **API security (OAuth2, JWT), database indexing strategies, and connection pooling**. --- ## 🛠️ Tech Stack & Systems ### Languages & Runtimes     ### Databases & Caching     ### Message Brokers & Streaming    --- ## 📊 Performance Statistics ```text API Average Response Time ████░░░░░░░░░░░░░░░░░░░░░ 18ms (99th percentile) DB Query Latency ██░░░░░░░░░░░░░░░░░░░░░░░ 2.4ms (Indexed queries) Cache Hit Ratio ████████████████████░░░░░ 87.4% Dockerized Microservices █████████████████████████ 100% Fully Orchestrated ``` --- ## 🚀 Featured Back-End Systems ### 🛡️ IronGate Gateway An enterprise-grade API gateway and reverse proxy supporting rate limiting, dynamic routing, and telemetry collection. - **Stack:** Go, gRPC, Redis, Prometheus - **Performance:** Routed 2B+ requests with a p99 latency of 1.4ms. ### 📦 StreamSync A real-time data ingestion pipeline designed for high-throughput log processing. - **Stack:** Rust, Apache Kafka, Elasticsearch - **Scalability:** Handles 15TB of raw telemetry logs per day. --- ## 🤝 Let's Connect <p align="center"> <i>⭐️ From <a href="https://github.com/your-username">your-username</a> — Building resilient backends. ⚙️</i> </p>
