Data and AI Solutions for Banking and Financial Services

Modernize core data, detect fraud in real time, sharpen credit decisions and meet supervisory expectations with governed data platforms and explainable AI built for regulated finance.

Turn Financial Data into Faster, Safer Decisions

Banks, credit unions, lenders, wealth managers and fintechs sit on some of the richest data in any industry: transactions, payment messages, credit histories, customer interactions and market feeds. Yet much of it is locked in decades-old cores, overnight batch jobs and spreadsheets that feed regulatory returns. Modern data platforms, machine learning and cloud infrastructure let institutions act on that data in seconds rather than days, from blocking a mule payment to pre-approving a small business loan.

Hanoi Technology helps financial institutions build that capability without compromising control. We design lakehouse and warehouse platforms with lineage that satisfies auditors, deploy fraud and credit models with documentation that model risk teams can validate, and build the APIs that open banking and embedded finance depend on. Every engagement is planned around your supervisory obligations, not bolted on afterwards.

The Challenge

The Data Challenges Facing Financial Institutions

Regulators, fraudsters and digital-native competitors are all moving faster, and legacy data estates struggle to keep up.

Fragmented Legacy Cores and Batch Data

Customer, account and transaction data is spread across core banking, card, lending and treasury systems that were never designed to share it. Overnight batch extracts mean risk, finance and marketing work from different versions of yesterday.

Escalating Fraud and Financial Crime

Instant payments, authorized push payment scams and synthetic identities give criminals seconds to move money. Rules-based monitoring generates high false-positive volumes that overwhelm investigators while still missing new typologies.

Heavy and Changing Regulatory Load

Capital and liquidity reporting, BCBS 239 risk data aggregation principles, operational resilience rules such as the EU Digital Operational Resilience Act (DORA), and AI-specific obligations demand traceable, reconciled data. Manual reporting chains are slow, costly and hard to defend in an examination.

Model Risk and Explainability Requirements

Credit, pricing and fraud models must be documented, validated, monitored and explainable to customers and supervisors under guidance such as the US SR 11-7 model risk framework. Many promising machine learning projects stall because governance was not designed in from day one.

Business Value

What Modern Data and AI Deliver for Financial Services

Real-Time Fraud and AML Detection

Score payments, card transactions and onboarding events in milliseconds using behavioral and network features. Investigators spend their time on genuinely suspicious activity instead of clearing false alerts.

Sharper, Fairer Credit Decisions

Combine bureau, transaction and cash-flow data to approve good borrowers faster and price risk more accurately. Built-in fairness testing and reason codes keep decisions explainable.

Faster, Traceable Regulatory Reporting

Automated pipelines with end-to-end lineage shorten reporting cycles and reduce reconciliation effort. Auditors can trace every reported figure back to its source system.

A Single View of the Customer

Unify accounts, products, interactions and preferences into one governed profile. Relationship managers and digital channels can offer the next relevant product at the right moment.

Lower Operating Costs

Automate document-heavy processes such as KYC refresh, loan servicing and dispute handling with intelligent document processing and workflow. Teams handle higher volumes without proportional headcount growth.

Resilient, Scalable Infrastructure

Cloud and hybrid platforms designed with resilience testing, exit plans and third-party risk controls in mind. You scale for peak volumes while meeting operational resilience expectations.

Trust Is the Product in Financial Services

A bank’s data and AI capability is only as valuable as the confidence that supervisors, auditors and customers place in it. That is why we treat lineage, model documentation, access control and resilience as core features of every solution, delivered alongside the analytics rather than months later.

Use Cases

Banking and Financial Services Use Cases

Concrete scenarios where data and AI change outcomes for institutions and their customers.

Instant Payment Scam Prevention

A bank scores every outgoing instant payment against the customer’s normal behavior, the payee’s history and mule network signals. High-risk payments trigger a real-time warning or hold before money leaves the account.

Cash-Flow-Based SME Lending

A lender uses consented account transaction data to assess small businesses with thin credit files. Underwriters receive a recommended limit with reason codes, cutting decision time from days to hours.

Automated Regulatory Return Preparation

A finance team replaces spreadsheet consolidation with governed pipelines that populate reporting templates. Every figure carries lineage and data quality evidence for auditors.

Next-Best-Action for Retail Customers

Propensity models identify customers likely to need a mortgage, savings product or credit line increase. Digital channels and advisors receive timely, compliant offers instead of broad campaigns.

KYC Refresh with Document AI

Generative and extraction models read identity documents, company registries and ownership statements. Analysts review pre-filled profiles and discrepancies rather than re-keying data.

Collections Prioritization

Early-warning models predict which borrowers are likely to fall behind and which contact strategy works best. Collections teams intervene earlier with more appropriate, customer-friendly options.

Banking and Financial Services FAQ

Can you work within our regulatory and security requirements?

Yes. Every engagement starts by mapping the obligations that apply to the initiative, such as data residency, outsourcing and third-party risk rules, operational resilience requirements and model risk guidance. We then design access controls, encryption, logging and documentation to match. Our engineers can work inside your environments with your identity controls, so production customer data does not need to leave your infrastructure. We also provide the evidence your security, procurement and compliance teams typically request during onboarding.

How do you make machine learning models acceptable to model risk and validation teams?

We develop models with validation in mind from the first sprint. That means documented data sources and assumptions, reproducible training pipelines, benchmark comparisons against simpler models, stability and sensitivity testing, fairness analysis where relevant and reason codes for individual decisions. We produce a documentation pack structured around your model risk policy and set up post-deployment monitoring for drift and performance, so validators can review a complete, traceable package rather than reverse-engineering notebooks.

What does a typical fraud detection project involve and how long does it take?

A first release usually focuses on one channel, such as card-not-present payments or instant transfers. We profile historical labeled data, engineer behavioral and network features, train and back-test models and integrate scoring with your payment flow or case management tool. A pilot running in shadow mode alongside existing rules can typically be ready in about three to four months, depending on data access and integration complexity. Shadow mode lets you compare results before switching decisions over.

Can you help with ISO 20022 payment data?

Yes. The migration to ISO 20022 gives institutions structured, richer remittance and party information than legacy formats. We build parsers and data models that capture this structure, feed it into analytics and screening, and improve sanctions and fraud detection accuracy. We can also help reconcile legacy and ISO 20022 data during coexistence periods so reporting and analytics remain consistent while different payment systems migrate on different timelines.

Do you work with our core banking platform?

We integrate with core, card, lending and payment platforms through their APIs, database replicas, event streams or file interfaces, depending on what the vendor and your architecture allow. We prefer change data capture or event streaming where possible to move from overnight batch to near real-time data. We do not replace your core system; instead we make its data accessible and trustworthy for analytics, AI and digital channels while respecting change-management controls.

What engagement models do you offer to banks and fintechs?

You can engage us for a fixed-scope project, such as a reporting data mart or fraud model, a dedicated team that works as an extension of your data and engineering organization, or managed services where we operate pipelines and models in production. All models include weekly written progress updates and sprint demos. Many institutions start with a short discovery or proof of value and then scale to a dedicated team once the first use case is in production.
