https://invoice-app-frontend-7w4zdec5o-bagas-naufal96-yahoocoid.vercel.app/The Toptal React Accelerator is an exclusive learning program that educates JavaScript developers in React, Next.js, Redux, and GraphQL. This is a 2-month program that consists of rigorous learning exercises and hands-on activities, a stringent evaluation process, comprehensive learning assessments, and 30-40 hours of building an Invoice Management System. Within this invoicing application, users can track invoices, clients, and company information.
Leadership.dev
A full stack, custom JavaScript project with a Firebase authentication, database, and storage back end. I implemented the member login and signup form using Firebase authentication and Kanban board pages for authorized members using Webix UI. Charged with architecting the web to accommodate the client's needs.
School Of Life PPA Website (Landing Page)
A website to sell and advertise an online school visited by thousands during the registration opening. Developed using HTML, CSS, JavaScript. I was also responsible for hosting, deployment, tester, and quality assurance. This was made as a freelance job from one of Wumbo Group's clients in marketing and online education.
MP Store Website (eCommerce)
I built an online store to sell products such as gold, drinks, vitamins, and online school enrollment. Besides eCommerce, this website also has a member area where people can help sell products and get rewards. Developed using HTML, CSS, PHP, and JavaScript.

Smart Garbage Monitoring
A system to monitor the locations and capacity of garbage bins in an area (city/district). The system can be monitored on a web dashboard and mobile app. I programmed the embedded system for garbage bins, configured the cloud platform, and made the mobile app for the system. An embedded system is made using NodeMCU ESP32. The cloud platforms used are ThingsBoard and ThingSpeak. The mobile app is made with Android Studio using Java, XML, SQLite, notifications, and WebView. I developed this as my Bachelor's degree thesis work. An earlier prototype of this project was also proposed and presented during the Digital Talent Scholarship 2019.
IoT-based School Permission Application
An early prototype of an Android application to submit permission reports regarding the absence of the students. The student can submit a permission report with a form of date, name, major, reason, and a photo of the proof (selfie or formal letter). The submitted report is sent into a Firebase database, which can be accessed by the teachers via the web or the app itself, requiring the teachers to log in to the application. I built this with Android Studio, using Java, XML, SQLite implementing REST, JSON, Firebase cloud, SQLite database, and image capturing. This was created as a freelance job from one of Wumbo Group's clients in the field of informatics engineering.
Fertigation for Drip Irrigation System
A fertigation system for drip irrigation, implemented on crops planted on the soil to ensure plants get enough water and the right temperature. I took charge of the mobile app, how it integrates with the plant system, gets data, and makes the UI for the users. Made with Android Studio, using Java, XML, SQLite implementing REST, JSON, ThingSpeak cloud, SQLite database, and notifications. Contributed to programming microcontrollers (Raspberry PI and Arduino using Python and C++). This integrates with the mobile app's sensors, modules, cloud, and control. I created a different implementation of a smart greenhouse for hydroponic plants. Participated in several competitions and proposed on program Kreativitas Mahasiswa 2017.
Smart Greenhouse for Hydrophonic Plants
A smart greenhouse system for hydroponic plants to ensure mobility, time efficiency, and plant healthiness. The plants' system can be controlled and monitored from afar from a mobile app and a website using the Internet of Things. I made the mobile app, how it integrates with the plant system, gets the data, and makes the UI for the users. Made with Android Studio, using Java, XML, SQLite implementing REST, JSON, cloud, database, and notifications. I also contributed to making the hydroponic plants and its container. This was created as my thesis project during my associate's degree. I also participated in several competitions in the fields of technology, agriculture, and scientific papers.
Wahana Sistem Kendali (Plane Control System)
A system to control the flight of a plane based on the plane's condition (roll, pitch, yaw). The plane is then monitored from the ground control station. The plane prototype is made and used several times. Components used are Electric Ducted Fan (EDF), Electronic Speed Control (ESC), microcontrollers (Arduino and PixHawk), and other electrical components. I was responsible for the plane prototypes used, measuring the optimal flight condition within the required resources and components. I also contributed to the electrical parts of the system. This project was made to compete in Kompetisi Muatan Roket Indonesia (Komurindo) 2017.
r1se
An online gaming platform that lets people earn money when playing motorsport video games, such as Asetto Corsa.
I implemented sophisticated back-end features, such as serverless architecture using the SST framework, error monitoring with Sentry, Auth0 for authentication, Hasura GraphQL for database, Shufti Pro for KYC, and a Stripe API for payment.
