• Developed backend services and media delivery pipelines for a production social media platform serving 5K+ downloads and 2K+ active users.
• Optimized adaptive video delivery and media pipelines, reducing playback latency by nearly 50% through streaming and backend optimizations.
• Maintained backend services and deployment pipelines, ensuring reliable production performance and high availability.

• Developing backend systems for a university platform (mess, internships, events, payments, biometrics) serving 3k+ users.
• Built scalable REST APIs handling 400–500 RPM using Node.js, PostgreSQL, and Redis caching for improved response performance.
• Implemented JWT-based RBAC and integrated payment and biometric services for secure, real-time workflows.

• Developed cross-platform mobile features using React Native and Flutter for event bookings and reservations.
• Worked with Supabase services, including authentication, real time infrastructure, and gRPC-based edge functions.

• Developed a dependency graph framework to identify malicious packages and transitive supply chain risks.
• Designed a multi-signal risk engine using metadata analysis, typosquatting detection, and dependency risk propagation.
• Integrated CI/CD security gates with automated dependency scanning and pre-deployment risk alerts.

• Built a semantic retrieval pipeline using Sentence-BERT embeddings and FAISS vector search to retrieve relevant documents, followed by ColBERT-style MaxSim re-ranking.
• Developed a hybrid ranking system combining vector similarity, BM25 lexical retrieval, and user-interest profiles with adaptive personalization weighting.
• Implemented click-based profile updates using exponential moving averages (EMA), FastAPI REST APIs, SQLite persistence, and a dashboard for analyzing retrieval results.
