Data Scientist building multimodal AI systems and reliable ML pipelines.
IndiaWhat I'm looking for
I’m a Data Scientist focused on building dependable AI systems—from memory architecture to end-to-end pipelines. At xCaliber Health, I designed a Redis-backed multi-agent session memory system, shaped the memory graph schema for incremental evaluation, and implemented ETL pipelines across Temporal workflows for EHR and claims scoring.
I also build multimodal agents for voice and chat with modular STT, LLM reasoning, and TTS pipelines, plus structured clinical data access via an in-house healthcare query language. Alongside my role, I’ve delivered projects like a microservices AI interview platform (Kubernetes + semantic retrieval) and applied ML for anomaly detection and phishing detection, strengthening my approach to testing, CI/CD, and measurable outcomes.
