Retrieval-Augmented Generation — answers grounded in Rahul's actual resume & experience

I’m a Full Stack AI Engineer and Technical Lead with 10+ years of experience building high-performance, scalable systems — currently at Tower Research Capital, a global high-frequency trading firm, where I architect products for the Risk & Referential Data division and lead a team of 5 engineers.

I’m pursuing an MS in AI & Machine Learning from IIITB, Bangalore (in collaboration with Liverpool John Moores University), deepening my expertise in the intersection of AI and software engineering.

My career spans investment banking, HFT, e-commerce, and fintech — building real-time systems, design token frameworks, trading platforms, and AI-powered tools. I’m passionate about leveraging AI to build products that are fast, intelligent, and delightful.
