About

Where AI Meets
Software Engineering

I'm a Principal Software Engineer at Portonics Limited, building intelligent systems that serve millions across South and Southeast Asia — for clients like Robi Axiata, DTAC Thailand, Telenor, and Grameenphone.

Beyond backend engineering, I'm deeply invested in the AI/ML revolution. From earning Google Cloud's Gold League with 15+ skill badges across Vertex AI, Gemini, NLP, and Computer Vision — to certifications in LangGraph, Prompt Engineering (Vanderbilt), and Mathematics for ML (DeepLearning.AI) — I'm building at the intersection of scalable systems and artificial intelligence.
