About
I am a full-stack engineer working on production AI systems and backend infrastructure. I currently build an LLM-powered workflow platform at a Singapore-based HR tech company.
I own technical decisions from architecture through code review, and I work directly with product and business stakeholders to set requirements and priorities.
