Academic Background
Bachelor of Computer Science (Informatics Engineering)
Universitas Putra Indonesia "YPTK" Padang
2022 - 2026GPA 3.26 / 4.00
Completed undergraduate coursework in software engineering, web programming, data structures and algorithms, and relational database systems. Undergraduate thesis research developed an LSTM-based tropical cyclone trajectory forecasting system evaluated across 12 experimental scenarios (14.2 km mean Haversine error, R² 0.999), converting the optimal model into ONNX format for direct in-browser execution via ONNX Runtime on an interactive Astro Island Architecture map.

04 / Background & Engineering Approach
Foundational Disciplines & Technical PrinciplesProfile & Background
I am Ikhwan Ramadhan, an Informatics Engineering graduate from Universitas Putra Indonesia “YPTK” Padang specializing in frontend web development with React and Next.js. My engineering work focuses on constructing responsive user interfaces, separating client-side UI state (Zustand, Signals) from asynchronous server state (TanStack Query, Axios), enforcing schema validation (Zod), and implementing role-based authentication (NextAuth, RBAC).
Operating as a T-shaped Frontend Developer, I pair deep client-side specialization with adaptive working knowledge of relational databases and backend services (PostgreSQL, MySQL, Prisma ORM). This cross-layer literacy enables me to align frontend state structures directly with API contracts and collaborate effectively across the software stack.
