What's Next

Looking forward

Beyond my current engineering work, I'm actively working towards the intersection of software engineering and artificial intelligence. I believe the next generation of backend systems won't just process data — they'll reason about it.

My goal is to deepen my understanding of AI integration within production environments: applying large language models, building intelligent APIs, and contributing to projects where machine learning genuinely enhances real-world software. I approach this with the same engineering rigour I bring to backend systems — focused on reliability, scalability, and measurable impact.
