Hi, I'm Sarah Nurhaliza
I architect powerful backend systems and bring them to life on the web — building from the core out, with clean logic and elegant interfaces.
I'm a Semester 4 student at CEP-CCIT FTUI (Faculty of Engineering, Universitas Indonesia), specializing in Full Stack Development with a deep focus on Backend Architecture & Native Web Development.
My passion lies in understanding how systems work at their core — building robust, scalable backend logic and connecting it seamlessly to the web. I believe a great developer doesn't just write code; they design systems that stand the test of time.
Like a butterfly, I'm always evolving — transforming challenges into elegant solutions. Like a sunflower, I grow toward the light: always learning, always reaching further.

Backend & Full Stack Web
HTML5, CSS3, PHP Native
MySQL, JDBC, RESTful API
Adaptive, curious, detail-oriented
RESTful API development with layered architecture, dependency injection, and Spring Security.
Deep HTTP flow understanding — routing, sessions, headers, and raw server-side logic without frameworks.
Standalone GUI applications with event-driven architecture and direct database connectivity.
Designing systems around asynchronous events and message-passing patterns for scalable apps.
Expert-level relational database design, complex queries, and ORM mapping with JPA/Hibernate.
Containerizing applications and services for consistent, reproducible deployment environments.
Automated testing and deployment workflows for continuous integration and delivery practices.
Building services that communicate across networks with reliability and fault tolerance in mind.
Pure semantic markup and modern CSS — no framework dependency, full control over the output.
DOM manipulation, async/await, fetch API, and interactive UI without relying on external libraries.
Swing and AWT component design, layout managers, and custom-painted user interface elements.
Fluid layouts, media queries, and mobile-first thinking for great UX across all screen sizes.
High-performance RESTful API for the Distributed System module — manages lab equipment logs and student transactions with automated reporting.
Digitized pharmacy operations — built with PHP Native and zero framework dependency, containerized with Docker for consistent deployment across environments.
Standalone desktop app for real-time stock and supplier management. Direct JDBC — no ORM abstraction, full control over queries.
Gamified educational platform concept — puzzles and logic challenges designed to make learning engaging for all ages.
I'm open to internship opportunities, backend system discussions, and web development collaborations. Let's build something great together!
