Projects Fajar Developed

From COVID-19 risk mapper, competition-winning software, to secure cryptographic protocol.

Pseudonymous Authentication Protocol

I addressed the challenge of enabling authenticated access to a third-party service without revealing user identities. I designed and implemented a privacy-preserving authentication protocol, developing a full-stack prototype to demonstrate its functionality. Formal verification with ProVerif confirmed the protocol’s security properties, and the master’s thesis work received a very good grade (4/5).

IoT System Tracking Dashboard

For a client project, I developed the Android app for Smoke Beefs, an IoT-based animal growth tracking system. The app functioned as a real-time monitoring dashboard for livestock growth data. The project won bronze medal on a prestigious national competition, highlighting its innovation and technical excellence.

COVID-19 Risk Mapper

I tackled the challenge of improving community COVID-19 risk assessment by combining diverse data sources. I developed AHPSAW, an advanced risk mapping model integrating medical, geographic, demographic, and meteorological data. The model calculates the risks using analytical methods and machine learning. The calculation was designed according to research about factors affecting COVID-19 spread. The project achieved the maximum grade as my bachelor’s thesis.

Farmer-Agronomist Forum

To solve the challenge of farmers lacking guidance on what crops to plant and when to plant them, I developed a mobile app that connects farmers with agronomists for agricultural guidance. The project was delivered as a client project.

Product Catalogue

To showcase their products, I developed a website for a client, who manufactures leather goods. I used WordPress so that my clients do not need me if they want to change something in the website, no coding skills needed.
