Project_Overview

The client managed critical financial data across dozens of fragmented spreadsheets — a workflow prone to version conflicts, data loss, and calculation errors. We built a centralized, production-grade web platform enabling secure Excel ingestion, automated financial operations, relational data storage, and role-based access for analysts, accountants, and managers.

Operational_Process

Designed a robust PostgreSQL schema for high-relational financial records. Built a FastAPI ingestion pipeline with real-time validation using Pydantic. Developed custom Pandas/NumPy modules for financial transformations. Created a ReactJS dashboard for file management, data visualization, and user administration. Deployed via Docker on AWS with full encryption.

Core_Capabilities

Drag-and-drop Excel ingestion with real-time validation and error reporting
Custom financial calculation engine for batch updates, interest, and rebalancing
Role-based access control (RBAC) for analysts, managers, and admins
Historical data archiving with full audit trail and version history
Asynchronous background processing (Celery/Redis) for large file uploads
Interactive data visualization dashboards for portfolio performance
Pydantic validation layer with detailed 'dirty data' error reports
Docker containerized deployment with SSL and database encryption at rest

Conflict_Resolution

Solution

Implemented asynchronous background processing using Celery and Redis, allowing users to continue working while files process in the background — eliminating all timeouts.

Resolution_Status: OKProtocol: Direct_Intervention
Solution

Built a Pydantic + Pandas validation layer that audits file structure before storage and returns a detailed, human-readable error report for any 'dirty' data.

Resolution_Status: OKProtocol: Direct_Intervention
Solution

Engineered a Python calculation engine using the Decimal module with full unit test coverage, ensuring every interest and reconciliation calculation matched legacy audit requirements.

Resolution_Status: OKProtocol: Direct_Intervention
Solution

Containerized with Docker, enforced SSL, stored all secrets via environment variables, and implemented PostgreSQL encryption at rest — meeting financial-grade security standards.
