Core WealthTech & Financial Aggregation Capabilities

  • Plaid, Yodlee, MX & Custodian Integrations: Synchronizing multi-institution brokerage holdings, bank transactions, liabilities, and cost-basis lots with idempotent webhook reconciliation.
  • Quantitative Portfolio Analytics in Python: Computing time-weighted return (TWR), internal rate of return (IRR/XIRR), Sharpe ratio, asset allocation drift, and tax-loss harvesting opportunities with Pandas/Polars and PostgreSQL.
  • AI Financial Analyst Copilots: Enabling wealth advisors to query client portfolios, SEC 10-K/10-Q filings, and earnings transcripts using secure, tenant-isolated RAG pipelines.

Frequently Asked Questions

How do you prevent floating-point rounding errors in financial portfolio calculations?

All monetary values and share quantities use exact fixed-point `NUMERIC` / `Decimal` arithmetic in PostgreSQL and Python—never IEEE 754 binary floats.
