Pijar Sekolah Ahmad Khairul Anwar

Project Overview

Pijar Sekolah is a nationwide digital learning platform in Indonesia, designed to support teachers and students with tools such as virtual classrooms, online assignments, computer-based tests, real-time chat, and learning dashboards.

My Contribution

Migrated project from monolith to micro frontend architecture, with new features built using Next.js and shadcn/ui for improved scalability.
Continuously adopted the latest technologies: upgraded Tailwind CSS (v1 → v3), Webpack (v4 → v5), and migrated from Enzyme to React Testing Library without breaking production code.
Maintained unit testing at 80% to comply with SonarQube standards, ensuring production-readiness.
Promoted to Project Lead and became maintainer, responsible for overall code quality and release stability.
Successfully deployed production builds via CI/CD pipeline using Jenkins, and fixed critical bugs identified by SonarQube under tight deadlines before major releases — achieving SonarQube A-score.
Integrated Firebase for real-time chat and notifications, significantly reducing latency and improving user engagement.
Implemented a validation function to detect and reject malicious JavaScript injection attempts embedded within uploaded PDF files.
Developed interactive charts using React ApexChart, handling edge cases such as empty states, large datasets, and dynamic resizing.
Applied performance optimizations: lazy loading, image format conversion to WebP.
Leveraged tools like ESLint to detect bottlenecks and fine-tune performance.
Implemented Google Analytics (GA) and Microsoft Clarity heatmaps to give the ops team actionable insights for improving promotions and platform usage visibility.

Introduction

After completing a three-month Fullstack JavaScript bootcamp, I joined Tribe Education (Telkom Indonesia) as a Front-End Developer. During my probation period, I was assigned to the Pijar Sekolah project, where I contributed to building scalable features, writing unit tests, and maintaining performance standards.

Upon successfully passing my probation with strong evaluations, I was promoted from entry-level Front-End Developer to Junior Developer. Over the next three years, I continued to grow and take on larger responsibilities—eventually being promoted to Lead Front-End Developer at the mid-level, overseeing development quality and mentoring other team members.
