Swapnil Dwivedi

B.Tech Data Science & Computer Science, VIT Vellore (2026).

I build data and ML systems, and I'm more interested in whether a result holds up than in whether it looks good. Most of the repositories below contain at least one measurement that came out the wrong way and stayed in the README.

Selected work

Project What it is
rxinsight A pharmaceutical commercial analytics warehouse. PostgreSQL star schema, Slowly Changing Dimensions, a streaming Python ETL over 2.2M rows, and window-function SQL. 36 tests.
MedGraph Agentic clinical document intelligence. A LangGraph state machine that answers from public healthcare policy and drug-label corpora — or refuses, with a stated reason, when the corpus can't support an answer.
anchor A retrieval-augmented QA and agent service whose centrepiece is the measurement layer that says where its retrieval actually fails. Runs with no API keys and no network calls.
modelwatch When a drift monitor fires, has the model actually degraded? Benchmarks drift detectors against realised degradation on real US Census windows, with ground truth the detectors never see.
mlops-portfolio Model serving end to end — FastAPI behind Docker, real-time inference over Kafka, Terraform for infrastructure, deployed to Kubernetes.
visiondoc-ai Vision-language document understanding, LoRA fine-tuned on consumer hardware and benchmarked against a zero-shot baseline.

What I work with

Languages Python, SQL Data PostgreSQL, pandas, PySpark, Databricks, ETL and dimensional modelling Infrastructure Docker, Kubernetes, Terraform, AWS, FastAPI, GitHub Actions ML PyTorch, TensorFlow, scikit-learn, LoRA/PEFT, RAG, LangGraph

Currently

Finishing my B.Tech and looking for data engineering and ML engineering work.
