Gonitzoggo is an online math and physics problem-solving platform I built to support Olympiad aspirants and STEM enthusiasts. Since launch in 2017, it has grown to over 30,000 registered users with around 5,000 monthly active users, and was recognized as the best online math platform by BdMO in 2023. I built the platform with Laravel 12, using Redis for caching and writing a custom rating algorithm in Rust to improve performance and accuracy. I designed the frontend with Metro UI CSS to keep the interface clean and lightweight. I introduced background jobs to offload heavy tasks and added real-time contest updates and notifications with WebSockets. I containerized the entire application with Docker and deployed it on Kubernetes. I also built a complete GitLab CI/CD pipeline to manage multiple environments — development, QA, and production — in their own namespaces. The pipeline automatically syncs databases across downstream environments, spins up temporary review environments for merge request previews, and supports horizontal autoscaling. Traffic routing and load balancing are handled through NGINX Ingress. I currently lead a team of over 40 people across engineering, marketing, and operations, and continue to evolve the platform every day. With a scalable infrastructure, a robust deployment pipeline, and a strong focus on user experience, I’ve helped grow Gonitzoggo into one of the most widely used platforms for competitive problem solving in Bangladesh.
