Backend-focused engineer building reliable systems, secure APIs, and AI-enabled tools.
I am a computer science student with a strong focus on backend engineering and system design.
- Solid foundation in Data Structures & Algorithms
- Experience building scalable backend systems
- Interested in distributed systems and real-time architectures
- Working on AI/LLM-based applications (RAG, agents)
I focus on building systems that are clean, practical, and production-ready.
