Academic Portfolio & Technical Foundation


FROM PROFESSIONAL EXPERIENCE TO CORE FOUNDATIONS

If you have arrived here from my CV, you already have an overview of my professional journey and the impact I have delivered over the past year across various organizations.

This GitHub profile serves as a Technical Deep-Dive — a dedicated space showcasing the foundational projects that shaped my logical framework and analytical methodology during my time at the University of Social Sciences and Humanities (USSH).

While my professional experience focuses on immediate business value, these academic repositories demonstrate my ability to transform ambiguous business needs into structured, scalable, and technically viable system designs.


CORE COMPETENCIES IN FOCUS

Throughout these projects, my contributions centered on the intersection of business logic and system architecture, embodied in three primary roles:

SYSTEM ANALYSIS & SPECIFICATION I specialize in deconstructing complex requirements into high-precision technical documentation. My work involves user research, process mapping (BPMN), and standardizing functional requirements (SRS, User Stories, and Acceptance Criteria) to ensure seamless handovers between business and engineering teams.

DATA & SYSTEM ARCHITECTURE I approach every problem with a "Database-First" mindset. My projects involve hands-on relational modeling (ERD/RDM), crafting complex business logic within SQL environments, and designing data flows that prioritize integrity and future scalability.

INTEGRATED SOLUTION DESIGN I focus on the "Big Picture" — designing systems that don't just work, but evolve. This includes implementing end-to-end ERP workflows (Odoo), leveraging Low-code automation, and exploring the integration of AI/Computer Vision to solve modern operational challenges.
