Software Engineer & Information Systems Student
An Information Systems student exploring how to build simple web applications to streamline daily workflows.
My Story
Engineering Mindset
I am an Information Systems student and software engineer who believes that code is just a tool to solve real-world problems. My interest in technology started from observing how inefficient manual business processes can be transformed into streamlined digital workflows.
Rather than just writing code, I focus on understanding the business domain. For instance, when building the complaint management system for PLN UPDL Palembang, the real challenge wasn't just technical—it was designing a flow that actual staff members would find easier to use than their old paper-based habits.
I enjoy taking ownership of a problem from concept to deployment. I strive to build applications that are not only performant and scalable under the hood, but also intuitive and fast for the end user.
What I use
Technical Expertise
Frontend & UI Engineering
I don't just build interfaces; I build experiences. Using React and Next.js, I architect scalable component systems and ensure high performance through server-side rendering and static generation. Tailwind CSS allows me to translate complex designs into pixel-perfect, responsive layouts rapidly without writing bloated CSS files.
Backend & System Design
A robust frontend needs a solid foundation. I design secure REST APIs and manage databases using PostgreSQL and MySQL. Whether I'm building a custom backend with Node.js/PHP or leveraging BaaS solutions like Supabase to accelerate development, my focus is always on data integrity, security, and scalability.
Automation & Integration
I love automating repetitive workflows to save hours of manual labor. I frequently use Google Apps Script to turn Google Sheets into powerful headless CMS or trigger-based backends, integrating them with Telegram Bots or WhatsApp APIs for real-time notifications and operations.
Tooling & Environment
Efficiency in development comes from mastering the right tools. I rely heavily on Git for version control and collaborative workflows, and GitHub Actions for simple CI/CD pipelines. My editor of choice is VS Code, deeply customized for my specific tech stack.
What I've built
Selected Work
PLN Pulse Check UPDL - Complaint Management System
The existing reporting system was highly passive. Users reported issues through a digital form, but facility admins had no way of knowing a report existed in real-time. This created a long time gap between when an issue was reported and when repairs began, purely due to the admins' lack of awareness.

Digital Signage - PLN UPDL Palembang
The schedule data is actually available, but it was only used for internal operational needs. TVs in public areas were not utilized as real-time information media, so participants still had to ask the staff. As a result, information was not disseminated proactively.
Modular PDF Generator
A Python-based workspace for generating modular and reusable PDFs. Specifically designed for AI-assisted workflows, it separates content (JSON/Markdown) from layout to ensure stability and maintainability.
Employee Self-Service (ESS) Portal
A modern, mobile-first human resource management portal featuring Role-Based Access Control, GPS geolocation attendance, leave management, automated payslip generation, and real-time notifications.

HUBEKS HIMSI
A specialized organizational management system for HIMSI's External Relations division. Digitalizes member data, media partnerships, and MoU storage, replacing manual processes with a streamlined digital workflow.
