• Built and led a school-wide emotion tracking system that logged 1K+ daily entries, provided teachers with dashboards (daily/weekly/monthly), and triggered adaptive therapy interventions using heuristics/ML models, reducing unaddressed cases by 25%.
• Designed and delivered a web app mapping students’ future career paths, implementing client-side compression and server validation pipelines to boost responsiveness (upload latency down 40%, validation time down 44%).
• Developed the Euro Kids Chatbot by building a production-grade RAG stack that fused semantic retrieval (FAISS with IVFPQ) and syntactic search (Whoosh) with intent-filtered query rewriting and prompt-engineering strategies, delivering structure-aware responses to franchisee queries. Optimized retrieval latency by tuning IVFPQ search parameters and re-ranker thresholds, reducing median response time from 480ms to 310ms and automating 80% of queries, which scaled support throughput by 2.5×.
• and reducing infrastructure costs by 35%.
• Built and scaled backend services using Java + Spring Boot, constructing REST APIs, data ingestion pipelines, and orchestration logic, which improved response times by 30% and enabled scalable integrations.
• Implemented an Academic Year Transition feature to allow seamless context switching across academic periods while preserving full historical data, ensuring 100% data integrity and increasing efficiency by 30%.
• Led code reviews and enforced modular architecture with best practices for maintainability and performance.
• Resolved 50+ P0/P1 issues, maintaining 99.9% uptime, and led rapid incident response across teams in Agile cycles.
