Data and AI Solutions for the Public Sector
Modernize legacy systems, deliver accessible digital services and use data and AI responsibly to serve residents better, with security and accountability built in.
Better Public Services Through Data and AI
Government agencies, municipalities, public health bodies, education authorities and state-owned enterprises hold data that could transform how services are delivered: benefits and tax records, case files, permits, transport, environmental sensors and service interactions. Yet many depend on decades-old mainframes, paper-based forms and siloed departmental databases. Cloud platforms, modern data architecture and responsible AI let agencies simplify services, detect improper payments and make policy decisions with better evidence.
Hanoi Technology helps public organizations make that shift carefully. We modernize legacy applications and data step by step, build accessible digital services, design data sharing with privacy and legal safeguards and implement AI with the inventories, impact assessments and human oversight that public-sector AI policies, such as US OMB guidance and the EU AI Act, increasingly require.
The Challenge
The Data Challenges Facing Public Organizations
Public bodies face rising expectations with constrained budgets, legacy technology and strict accountability.
Aging Legacy Systems
Core systems for benefits, licensing, tax and case management often run on mainframes or unsupported platforms, written in languages few engineers still know. Every policy change is slow and risky to implement.
Siloed Data Across Agencies
Departments collect the same information from residents repeatedly because data cannot be shared safely between them. Analysts struggle to see the full picture needed for policy evaluation or fraud prevention.
Accountability and Responsible AI Obligations
Public-sector AI must be transparent, fair and contestable. Policies such as US federal AI use case inventories and risk management practices, and the EU AI Act’s obligations for high-risk public uses, require documentation, impact assessment and human oversight.
Security, Sovereignty and Procurement Constraints
Agencies must meet strict security frameworks, data residency rules and procurement processes, such as FedRAMP in the US. These requirements are essential but can slow adoption of modern cloud and AI services without careful planning.
Business Value
What Modern Data and AI Deliver for Government
Simpler Digital Services
Accessible online services with pre-filled data and clear status tracking reduce calls, visits and errors. Residents complete tasks in minutes rather than weeks.
Reduced Fraud and Improper Payments
Analytics and data matching identify suspicious claims, duplicate payments and identity misuse before money is paid out. Investigators focus on the highest-risk cases.
Evidence-Based Policy
Integrated, well-governed data sets let analysts evaluate programs and model the impact of policy options. Decision makers see outcomes, not just activity counts.
Productive Public Servants
Automation and AI assistants handle routine correspondence, document classification and research. Caseworkers spend more time on complex cases and direct contact with residents.
Lower Legacy Risk and Cost
Incremental modernization retires unsupported technology without risky big-bang replacements. Maintenance costs fall and policy changes become faster.
Trustworthy, Transparent AI
Documented models, impact assessments and appeal routes make AI decisions explainable to residents, auditors and oversight bodies.
Public Trust Must Be Designed In
Residents rarely get to choose their government service provider, so the bar for fairness, transparency and reliability is higher than in any market. We design public-sector data and AI solutions so that every automated step can be explained, audited and challenged.

Use Cases
Public Sector Use Cases
Examples of how data and AI improve services, integrity and policy.
Benefits Application Pre-Fill
With residents’ permission, an online application retrieves income and household data already held by other agencies. Applicants confirm instead of retyping, and processing errors fall.
Improper Payment Detection
A benefits agency matches payments against death registers, employment data and duplicate identities. Flagged cases go to caseworkers with explanations, not automated denials.
Contact Center Assistant
Agents ask a generative AI assistant about eligibility rules and procedures and receive answers with links to official guidance. Residents get consistent answers on the first call.
Permit and Licensing Digitization
Paper-based building permit applications move to an online service with document checks and status tracking. Applicants know where their case stands, and officers see workloads clearly.
Mainframe Benefits System Modernization
Business rules are extracted from legacy code and reimplemented service by service on a modern platform. The legacy system is retired gradually without interrupting payments.
Smart City Mobility Analytics
A municipality combines traffic sensors, public transport data and incident reports. Planners adjust signal timing and bus routes using evidence rather than anecdote.

Public Sector FAQ
How do you handle public-sector security requirements?
We design solutions to meet the frameworks that apply to your organization, such as FedRAMP and NIST controls in the United States or national cloud security standards elsewhere. That includes using authorized cloud services, documenting controls, implementing least-privilege access, logging and incident response procedures and supporting your assessors. Where data residency or citizenship requirements apply to personnel or hosting, we agree the delivery model during scoping.
How do you ensure AI is used responsibly in government?
We start with an impact assessment for each AI use case, covering purpose, data sources, potential harms, affected groups and the level of human oversight required. We document models for your AI use case inventory, test for bias and accuracy, ensure decisions affecting residents are reviewed by people and provide routes to explanation and appeal. Monitoring continues after deployment, and we align practices with applicable policies such as OMB guidance or the EU AI Act.
Can you modernize a mainframe system without disrupting services?
Yes, by avoiding big-bang replacements. We analyze the legacy code and data, extract business rules and migrate functions incrementally using patterns such as the strangler fig, where new services gradually take over from the old system. Data is synchronized during transition, and each step is tested in parallel with the legacy system. This approach reduces risk and lets the agency see value early.
How do you work within government procurement?
We can participate as a subcontractor to an established prime contractor or framework holder, or contract directly where procurement rules allow. We provide clear scope, deliverables and pricing to support your procurement process and are comfortable with milestone-based contracts. Our transparent delivery model, with weekly written updates and sprint demos, also supports the oversight and reporting expectations of public programs.
Do you make digital services accessible?
Accessibility is part of our definition of done, not a final audit. We design and test against WCAG 2.2 AA, use semantic markup, support screen readers and keyboard navigation and test with real users including people with disabilities where possible. We also consider plain language, multilingual content and assisted digital channels for residents who cannot or prefer not to use online services.
Can we own the solution after delivery?
Yes. We favor open standards, open-source components where appropriate and well-documented code that belongs to you. We plan knowledge transfer from the start, pairing with your staff, documenting architecture and operating procedures and running handover sessions. If you prefer, we can continue to support or operate the service under a managed services arrangement.
