Professional Summary
AI Engineer at Apexon (embedded at Goldman Sachs), with experience spanning quantitative finance, machine learning, and distributed systems.
Experience
-
2025 - Bangalore, India
AI Engineer
Apexon
Embedded at Goldman Sachs within the Reconciliation team.
- Shipped LangChain agents that normalize trade records across counterparty formats, grounded in a retrieval index of internal schemas with typed tool-use for field-level validation and canonicalization. Structured-output decoding plus schema-guided retrieval cut field-mapping errors against a prompt-only baseline in ops-team review.
- Developed an unsupervised anomaly detector (streaming Random Cut Forest via rrcf in Python) over high-dimensional counterparty trade feeds due to label sparsity and reconstruction baselines degrade under regime drift.
- Deployed a conversational root-cause analysis system over Snowflake that runs schema-agnostic text-to-query, pulls trade-lifecycle context, and produces grounded summaries of break root causes with resolution suggestions. Tuned retrieval and prompting against analyst-resolved tickets.
- Partnered with multiple clients across industries to design and demo AI-native solutions, including agentic payments orchestration for Mastercard and M11 regulatory protocol digitization for pharma clients.
