Casefiles
Casefile shelf
Each casefile ties a real research question to the surface I built to run it better.
I care about practical leverage more than decorative projects: consumer coverage support, crypto market review, derivatives study, Vietnam-market product design, and automation that reduces manual drag.
Portfolio lens
My standards come from sell-side research at Vietcap, credit and reporting work at BIDV, and academic research at UEH.
I extend that training into dashboards, pricing tools, and automation projects that behave like reusable analyst infrastructure.
I would start with VNIBB, then the crypto stack, then option pricing and AI workflows for the technical range.
