### 💡 Professional Summary

Backed by 7+ years of hands-on experience, I architect and implement robust backend systems that power high-performance applications across industries. My core strength lies in building distributed systems and scalable APIs using Node.js and TypeScript—always with an eye for maintainability, performance, and business impact.

From real-time communication engines to asynchronous workflows, I specialize in translating complex requirements into clean, modular, and testable code. Whether modernizing legacy codebases or building cloud-native microservices from the ground up, I bring strategic clarity, technical depth, and team spirit to every project.

### 🧠 What I Bring to the Table

* 🚀 Performance-Focused Engineering: Delivered low-latency systems that handle thousands of concurrent users with minimal resource consumption.
* 🧩 Modular System Design: Created scalable service-oriented backends with clear domain boundaries and async processing flows.
* 🔄 Process Automation & CI/CD: Integrated efficient CI pipelines and containerized deployments for zero-downtime rollouts.
* 👥 Collaborative Leadership: Mentored junior developers, led architectural discussions, and contributed to knowledge-sharing culture.
* 🧪 Quality First: Advocate of test-driven development and defensive programming practices—Jest is my go-to for backend test coverage.
