Aegis Bank — Agentic AI-Powered Banking
Inspiration
Traditional banking apps focus on transactions, while AI assistants often stop at answering questions. We wanted to explore what happens when banking becomes more intelligent, proactive, and action-oriented.
That inspired Aegis Bank — an agentic AI-powered banking platform that combines financial intelligence, autonomous analysis, and secure human-controlled workflows.
What it does
Aegis Bank is a functional digital banking prototype with dedicated customer and analyst workspaces.
Its key capabilities include:
- Agentic AI Assistant: Context-aware banking assistance using specialized AI agents.
- Personal Financial Intelligence: Spending insights, cash-flow analysis, budgeting, savings goals, and affordability estimates.
- Proactive AI Agents: Scheduled financial reviews, security monitoring, expense detection, and savings coaching.
- Fraud Detection: Transaction risk analysis, unusual activity detection, security alerts, and analyst investigations.
- Smart Banking: Account management, transaction history, beneficiaries, and simulated fund transfers.
- Document Intelligence: Secure document uploads, information retrieval, and source-grounded answers.
- Human-in-the-Loop Security: Risk-based approvals, transaction holds, and auditable decisions.
All financial transactions operate in a simulated environment without moving real money.
How we built it
We developed Aegis Bank using a full-stack architecture that integrates AI capabilities with secure banking workflows.
GitHub Repository: https://github.com/satyamsahu40678/agies-bank
Frontend: Next.js, React, and TypeScript for responsive customer and analyst dashboards.
Backend: Python and FastAPI for banking operations, authentication, risk evaluation, and agent execution.
AI: Google Gemini with configurable support for OpenRouter, OpenAI, and Claude, alongside specialized financial analysis agents.
Database: Cloud Firestore for persistent application data, transaction records, agent workflows, and audit trails.
Cloud Infrastructure: Firebase Hosting, Google Cloud Run, Cloud Scheduler, and GitHub Actions for deployment and automation.
We designed the system so AI agents can analyze information and recommend actions, while sensitive banking operations remain controlled by backend policies and explicit user approvals.
Challenges we ran into
One of the biggest engineering challenges was balancing AI autonomy with financial security.
We focused on maintaining consistent transaction records, preventing duplicate payments, managing asynchronous agent workflows, handling AI-provider failures, and ensuring that automated recommendations never bypass authorization controls.
Integrating the frontend, backend, AI providers, database, and cloud infrastructure into a coherent application was another important challenge.
Accomplishments that we're proud of
We're proud of building more than a conversational AI demo.
Aegis Bank includes working banking simulations, persistent agent workflows, proactive financial analysis, explainable fraud alerts, document-based assistance, and separate customer and analyst experiences.
We also implemented a double-entry transaction ledger, risk-based transfer controls, audit records, and automated cloud deployment.
The result is a deployed prototype that demonstrates how agentic intelligence can operate within governed financial workflows.
What we learned
Building Aegis Bank strengthened our understanding of agentic AI architecture, full-stack engineering, financial workflows, cloud deployment, and AI security.
Our biggest takeaway was that reliable agentic systems require more than powerful models. They need controlled tools, persistent state, transparent decisions, robust error handling, and human oversight.
What's next for Aegis Bank
We plan to expand Aegis Bank with advanced financial forecasting, multimodal voice assistance, enhanced document OCR, deeper fraud intelligence, and more sophisticated financial automation.
Future development will also explore integrations with authorized banking and identity-verification providers, alongside stronger production security and regulatory controls.
Our vision is to make banking more intelligent, proactive, transparent, and secure.
