About
me.
Applied mathematics, technical building, and enterprise leadership—brought together in one operating profile.
APPLIED MATHEMATICS+ COMPUTER SCIENCE
MODELS → SYSTEMS → ORGANIZATIONS → NARRATIVES
I work across four connected layers: models systems organizations and narratives
Applied Mathematics + Computer Science at UC Davis gives me a formal foundation. Enterprise digitalization tests that foundation against people, responsibility, and real operational constraints.
01 / PRINCIPLES
Operating principles
Build systems, not isolated features
Connect data, states, interfaces, verification, and operational feedback.
Keep the human context
Efficiency matters, but so do accountability, language, and the people affected.

FELIX YANG / LEARNING
Start with structure
Applied Mathematics and Computer Science shape my studies at UC Davis.
With an unfamiliar technical problem, I start with objects, constraints, and relationships that can be tested.
FELIX YANG / IN THE FIELD
Work happens with people
A discussion is a reminder that people must understand and carry a process together.
A system needs clear responsibilities, handoffs, and exceptions to become part of daily work.
03 / OUTSIDE WORK
Leave room for life
Outside work and study, I enjoy baseball, climbing, skiing, working out, and baking

Enterprise Digital Transformation
A summer transformation project spanning operating processes, structured business data, internal systems, and the HARVESTFLOW digital brand portfolio.
- Standardized role responsibilities, attendance and leave policies, employee conduct, meeting cadence, and management documentation.
- Directed DEXIN Nebula, an internal operating platform connecting OA, HRM, CRM, SRM, inventory, finance, product data, BI, permissions, and audit trails.
- Structured product, pricing, and inventory data into a governed operating foundation for quotations, warehouse workflows, and management reporting.
- Coordinated the HARVESTFLOW corporate website and Dexiaoxin AI knowledge system as part of a unified digital business portfolio.
B.S. Applied Mathematics + Computer Science
An interdisciplinary course path spanning algorithms, numerical analysis, probability, computation, and the mathematical foundations behind reliable systems.
