At CustomerInsights.ai, I build AI agents and MCP servers for the Pharma Market Mix Modelling use case in the Athena product. I also built and evaluated a pharma-domain SLM fine-tuning pipeline, selecting a production model through BLEU-score benchmarking.

At SplashLearn, I migrated a mission-critical authentication service to Java and Spring Boot, shipping 20+ production REST APIs for students and teachers. I also built an AWS S3 bulk-upload pipeline and optimized APIs, cutting response times by about 40%.
