Ravi Vats

I’m Ravi Vats, a Lead Data Scientist at Thoughtworks, based in Singapore.

I have spent 7+ years building scalable backend services and AI/ML systems — from transformers and reinforcement learning to production-grade LLM applications. Earlier in my career I built high-traffic Go APIs with rate limiting, caching, and performance optimizations. These days I’m focused on RAG systems and LLM fine-tuning pipelines.

I write about the problems I’m solving and the patterns I discover along the way.

Previously

Before Thoughtworks, I was a Senior Software Engineer at Grab in Singapore, in the Deliveries organization — building Go microservices that handled 2M+ food and express-delivery orders per day. Before that, I worked at Morgan Stanley in the Institutional Securities Tech division, doing backend development and big-data engineering on post-trade reporting pipelines. I’ve also interned at Bosch (research, IoT/home automation) and worked on mobile apps early in my career.
