About me

OFF THE TERMINAL

I work at the intersection of graphs and reasoning — ranking and recommendation, search, graph neural networks, and the context systems that let a model reason over structure instead of flat text.

I’ve been the subject-matter expert on graph databases in both a Fortune 500 bank and an early-stage startup. What I’m working toward is patentable method work in that space, particularly in reasoning and context management.

I published two papers in 2026 during my MS in Computer Science and Engineering at the University at Buffalo. As a graduate researcher at ADAMS Lab, my thesis applied graph-based learning to order-preserving search and recommendation over combinatorial choices — mixed-integer and mixed combinatorial nonlinear optimization, where the space is discrete, non-convex, and large enough that solvers routinely stall short of a good answer. Our approach guides them toward globally feasible solutions faster; how much faster depends on the problem.

ONGOING PROJECTS
Open-source code infrastructure for Malayalam — a small language model first, then vector indexing and RAG pipelines that answer natively in Malayalam instead of round-tripping through English.
OFF THE CLOCK
I love art and music. I sometimes mix electronic music, but I have a profound liking for rock, indie, and Carnatic fusion. My evenings go to a walk or a run around the neighborhood. I love to climb, and to get out on my motorbike.

Experience

2019 — 2026
JUN 2025 — MAY 2026
BUFFALO, NY

AI Engineer — PhysicianX

  • Trained and evaluated Graph Neural Networks for link prediction on large-scale Neo4j knowledge graphs, extracting relationship-aware intelligence for user-facing recommendations.
  • Built a production-grade GraphRAG architecture pairing Neo4j retrieval with distributed multi-agent orchestration (Mastra Workflows, GraphQL), including context assembly and anti-hallucination guardrails.
  • Ran end-to-end distributed ML infrastructure on GCP — continuous deployment, evaluation, and large-scale data processing for high-throughput microservices.
  • Owned production support and CI/CD frameworks that cut deployment latency by 75%.
JAN 2025 — MAY 2026
UNIV. AT BUFFALO

Graduate Researcher

  • Developed the Edge Field Graph Network (EFGN), a first-of-its-kind technique that abstracts combinatorial design spaces by mapping a fully-connected undirected graph of choices to a directed graph encoding direction-of-improvement.
  • Trained EFGN via pairwise difference regression with a custom cyclical regularization loss, yielding an interpretable graph-based recommender inside an optimization loop.
  • Benchmarked against indexification baselines on three nonlinear problems with PSO and genetic-algorithm solvers, achieving better mean optima and run-to-run robustness.
SEP 2019 — JUL 2024
PUNE, INDIA

Staff Software Engineer — Credit Suisse AG

  • Led zero-downtime migrations of Neo4j Enterprise (v3 → v4 → v5) and Java (8 → 11 → 17) on a production distributed graph database, covering storage layer and query engine version changes at scale.
  • Subject Matter Expert for graph modeling and Cypher optimization, translating business needs into pipeline architecture spanning 20 global locations.
  • Built a fraud detection engine on graph mining, clustering and community detection across large-scale knowledge graphs.
  • Optimized ETL processes for an 80% increase in data processing efficiency, and built event-driven microservices on Kafka with partitioned, idempotent processing.
