Took full ownership of designing, developing, and scaling end-to-end web and mobile applications from scratch. Operating as a full-stack engineer, I managed the complete development lifecycle, bridging complex system architecture, cloud deployment, and custom algorithm creation.
- Designed, developed, and maintained end-to-end web and mobile applications across front-end, back-end, responsive UI, performance optimization, and third-party integrations.
- Built and scaled production-ready platforms from zero to production as a sole engineer, taking full ownership of system architecture, database modeling, cloud deployments, and API design.
- Engineered scalable RESTful Node.js backend services backed by PostgreSQL, deployed on Google Cloud Platform (GCP) with GCP Cloud Storage for optimized media handling.
- Architected layered Android applications using MVVM with a clean separation between the UI, domain, and data layers , utilizing RxJava, Retrofit, and OkHttp for reactive state and network communication.
- Developed a custom recommendation algorithm using a weighted scoring system to tailor user feeds dynamically based on real-time engagement (views, likes, comments).
- Orchestrated backend cron jobs for calculating and updating video statistics , while integrating Firebase for authentication/crash analytics and Amplitude for granular user behavioral tracking.
