Full-stack engineer in a small product team, owning AI-first products end to end across backend, frontend and infrastructure, working directly with product and data-science teams; mentored junior engineers through code reviews. • Designed RAG pipelines on LangChain over Anthropic and custom models, fine-tuning in PyTorch where domain accuracy required it, to power document generation and clinical decision support. • Built backend services in Java Spring Boot and Python/FastAPI for the AI layer, on PostgreSQL and MongoDB, with Redis and message queues for caching and asynchronous processing. • Built frontends in React.js and Vue.js under a micro-frontend architecture, including data-dense clinical and compliance screens. • Shipped AI into legal compliance workflows — dynamic document generation, regulatory classification and automated risk flagging using NLP and LLMs. • Deployed on AWS (EC2, S3, Lambda, RDS) with Docker; set up CI/CD, testing and observability practices that cut release turnaround. Key products • AI Hospital Management Platform — LLM-generated discharge reports, next-step suggestions for doctors, TPA insurance report generation, and admission-time disease prediction with high/medium/low priority scoring; RAG built on LangChain with a mix of custom and Anthropic models. • Marinadata.io — AI-powered regulatory change and compliance management platform using NLP to automate legal document generation, interpret regulatory updates, and streamline compliance workflows. • Sonarapi.com — open banking platform for real-time transaction monitoring and secure card connectivity, enabling personalised, context-aware customer interactions.

Bengaluru

Full-stack engineer on Goniyo's fintech platform, working across customer onboarding and mutual fund investment. • Built and scaled fintech infrastructure on Node.js, React.js, and AWS (Lambda, API Gateway, EC2, VPC). • Developed backend APIs on AWS Lambda and LoopBack, plus the internal admin panel in React.js using an SPA micro-frontend architecture. • Translated user requirements into functional specifications and low-level designs, then carried them through to production. • Ran maintenance for live modules — operational support, defect analysis, problem resolution, and preventative fixes — and built and tested analysis-pipeline components for production deployment.
