Finance Admin Portal & Automated Reconciliation System
Project Overview
Designed and built a comprehensive finance operations admin portal that enables internal teams to manage users, accounts, and financial transactions while automating transaction reconciliation between external banking data and internal records.
The platform acts as a central operational hub for finance teams, combining advanced data management tools, real-time transaction monitoring, reconciliation automation, and workflow scheduling within a scalable internal tool built in Retool.
In addition to providing full visibility into financial data, the system includes custom reconciliation algorithms that automatically match transactions from external banking integrations with internally recorded financial events.
Key Outcomes
Automated ~90% of transaction reconciliation
Reduced manual reconciliation workload dramatically
Created a centralized finance operations admin portal
Enabled teams to manage users, accounts, and financial records
Built scalable tools for handling large financial datasets
The Challenge
The client needed an internal system to manage a growing financial platform.
Key operational challenges included:
Managing multiple financial data tables across the system
Reconciling external bank transactions (via Plaid) with internal financial records
Monitoring account balances and transaction activity
Giving finance teams the ability to review, edit, and investigate records quickly
Handling large datasets without performance issues
Existing workflows relied heavily on manual processes and spreadsheets, which created operational inefficiencies and increased the risk of reconciliation errors.
The goal was to build a robust internal admin portal that could serve as the operational backbone of the financial system.
Key Technical Milestones
1. Full Finance Admin Portal
Built a feature-rich admin portal in Retool to manage the entire financial data ecosystem.
The portal provides tools for managing:
Users
Accounts
Transactions
Financial reconciliation
Operational workflows
Key capabilities include:
Advanced Data Tables
Complex relational tables for financial records
Inline editing for quick updates
Customizable table views
Collapsible rows for nested data
Dynamic filtering and sorting
This allows internal teams to explore and manage financial data efficiently without engineering support.
2. Financial Transaction Monitoring & Visualization
Implemented transaction analytics and visualization tools within the admin portal.
Features include:
Transaction volume monitoring
Account-level activity tracking
Financial data charts and visualizations
Real-time transaction inspection
These dashboards provide quick operational insights into financial activity across the platform.
3. Automated Reconciliation Engine
Developed a multi-layer transaction reconciliation system that automatically matches external banking transactions with internal records.
Custom reconciliation algorithms were written in JavaScript and Python, running as scheduled processes to reconcile transactions daily.
Matching Logic
Deterministic Matching
Transactions are matched using:
Transaction amount
Transaction date
Reference IDs
Keyword Matching
Transaction descriptions are analyzed to improve match accuracy when reference identifiers are missing.
Fee-Tolerant Matching
Transactions are allowed to reconcile when small differences exist due to processing fees within a defined threshold.
Partial Match Detection
Transactions that partially match are automatically flagged for review within the admin portal.
4. Bulk Reconciliation & Operations Workflows
The portal enables finance teams to perform operational actions efficiently.
Capabilities include:
Bulk reconciliation actions
Transaction approval workflows
Manual reconciliation overrides
Investigation of unmatched transactions
These workflows significantly reduce manual effort for financial operations teams.
5. Performance Optimization for Large Datasets
Since financial data volumes grow rapidly, performance optimization was critical.
Key improvements included:
Query Optimization
Optimized database queries and API calls to reduce response time.
Server-Side Filtering & Pagination
Large transaction tables are filtered directly at the backend to maintain fast UI performance.
Reusable Retool Modules
Built modular UI components reused across multiple admin pages.
Scheduled Workflows in Retool
Automated tasks run periodically to reconcile transactions and update financial records without manual intervention.
Impact
The admin portal significantly improved operational efficiency for the client’s financial platform.
Operational Improvements
Automated approximately 90% of transaction reconciliation
Reduced reconciliation time from hours of manual work to minutes
Enabled finance teams to manage large datasets through a centralized internal tool
Business Benefits
Improved financial data accuracy
Reduced operational overhead
Created a scalable system to support growing transaction volumes
