HLS Key Delivery Server allows simple authorization and precise playback permission controls for media broadcasting and VOD content streaming. It uses Node.js Express as server and Valkey as the database, enabling high performance and scalability.

INSPARS Q uses publicly available data sources, user generated feedback and combines them using a Machine Learning model to generate a reputation score for an IP address. INSPARS is a helpful tool for me to do network security related research.

Bus Management System allows bus compaines to easily track their incomes and expenses, contact their customers' easily, accept pre-registrations directly on the web and much more. Bus Management System also allows Bus Planning, which helps to easily organize the customer-bus places.

Derslik was an online education platform that was developed for my high school in response to COVID-19. It is very scalable and lightweight, and used for more than 850 lesson sessions and hundreds of meetings.

I developed front-end and managed networking performance. The project uses Flask for backend and Cloudflare for delivery optimization and security. We also integrated and customized Jitsi to enhance meeting capabilities.

Developed a series of apps and systems including Digital ID, SSO and Internal Network for my high school. I managed networking performance, front-end development and design. The internal network is actively used by students, teachers and teams.

In Syansita, we also operated a RIPE Atlas server and used our credits to perform analyses of networks to better understand network performance.

However, certain data related to your visit (including but not limited to your IP address, requested path, and User-Agent) may be collected by both the website operator and the service provider, Cloudflare, to prevent misuse, mitigate security threats, and protect against attacks. This processing falls under the category of "Legitimate Interest" under GDPR. The collected data will be used solely for security purposes and will not be used for targeting, advertisements, or analytics. It will be automatically deleted when no longer needed, kept confidential, and not shared with third parties except for Cloudflare as the service provider.

For analytical purposes, data collection is designed to be anonymous and privacy-friendly. Only broad, non-specific metrics are collected and these metrics are further aggregated for more privacy. This website also uses Cloudflare Web Analytics to measure performance and general usage trends.
