Senior🎓
Top SchoolAman Srivastava is a Lead Data Scientist based in Singapore with 11 years of experience building production-grade ML systems across search, recommendation, NLP, and risk modelling. At Pelago (Singapore Airlines) he led search, recommendation and chatbot teams driving 20% of platform bookings, shipping BERT-based semantic search, LTR/Elasticsearch ranking, FAISS de-duplication for 300K+ products and RAG-powered assistants that halved support tickets. He has deep hands-on experience optimizing pipelines to sub-200ms latency and scaling models for 100M+ user datasets from his time at Paytm and prior roles. An active open-source contributor, Aman enhanced text classification and multi-class probability prediction in the popular flairNLP project and improved multilingual NER and translation tooling for Haptik’s chatbot stack. Entrepreneurial by nature, he founded consumer apps (Notopass, Foodgreed) and open-sourced utilities like a spell-correction library, showing a knack for product-minded engineering. He pairs clear articulation and organisational rigor with a persistent hunger to refine models and systems for real-world impact.
