I work on the systems side of machine learning. Distributed training, retrieval, and the infrastructure that keeps models serving after the notebook is closed.

training     multi-node GPU pretraining of dense embedding models
retrieval    RAG over Qdrant and Neo4j, masking strategy ablations
backend      FastAPI, PostgreSQL, Alembic, REST
infra        AWS (ECS, S3, SQS, Cognito), Terraform, Docker, Slurm

Backend engineer at AceLink Software Solutions, working on Python services and AWS infrastructure.

Before that, eight months as a technical intern at BharatGen (IIT Bombay), working on distributed pretraining of dense embedding models on a multi-node GPU cluster: masking strategy ablations through pretraining and SFT, Slurm cluster tooling, and large-scale data migration to S3.

Reading about inference optimisation and distributed training internals.

Do UN Discussions Reduce Terrorism? An Empirical Study on Political Stability and Terrorism Casualties — B.Tech capstone, Department of Data Science, MPSTME.

Text-mined a UN Attention Score from UN Official Document System reports and merged it with Global Terrorism Database casualties and World Bank governance indicators into a 1995–2020 country-year panel. Estimated pooled OLS, fixed effects, random effects and two-step difference/System GMM to handle persistence and endogeneity. Political stability holds a robust negative association with casualties; discourse volume alone does not.
