Who this service is built for

This service fits companies that need a partner who does more than write code—one who understands operations and can stay engaged for the long term.

01

Legacy systems that are hard to maintain or scale

ARIS helps you leverage existing C# or Java assets while gradually shifting to web, API, and cloud—prioritizing risk-reduction paths that minimize operational disruption rather than all-at-once replacement.

02

Complex requirements that need a partner who understands operations

We support requirements clarification for workflows including proposals/approvals, sales, inventory, membership, contracts, reporting, notifications, and access control. We design not just for features, but for real operational fit.

03

Teams that value quality and governance as much as cost

ARIS helps you track progress, issues, change requests, and quality transparently—making us a fit for teams who want a reliable, long-term development partner.

04

Organizations wanting development, operations, and continuous improvement in one team

After go-live, ARIS can continue with additional development, incident response, performance optimization, and SLA-based maintenance. Our goal is not deliver-and-done—but systems that operate stably and improve over time.

What We Deliver

How ARIS can help

Depending on your business problem and operational requirements, ARIS can support across any or all of the areas below.

Core operational platforms
A

Business web system development

ARIS builds web systems for business operations—sales management, inventory, membership, contracts, proposals/approvals, and internal workflows. Designed with real needs in mind: access control, audit logs, notifications, search, reporting, CSV import/export, multilingual, and timezone support.

  • B2B admin panels, portals, and back-office systems
  • Forms, search, lists, approvals, notifications, reporting
  • Designed for maintainability and scalability
  • Supports complex integrations
Integration-ready backends
B

API development and system integration

We handle integration with ERP, CRM, accounting, payments, email, Zalo/LINE, SFTP, CSV, webhooks, and more. We also build business APIs and admin backends in PHP/Laravel, REST APIs with auth/authorization, batch jobs, async processing, and integration error handling.

  • REST API / Webhook / SFTP / CSV
  • OAuth2 / OIDC / SSO support
  • Batch job, queue, and async processing design
  • Phased migration-friendly
Phased restructuring
C

Legacy system modernization

Rather than replacing old systems all at once, ARIS prioritizes phased restructuring to minimize operational impact. We analyze existing code, data, and operations, then migrate by module or feature toward a more maintainable and sustainable architecture.

  • Desktop C# to web/API migration
  • Java restructuring, API-first, phased transition
  • Coverage includes data, reporting, and batch jobs
  • Support continues post go-live
Post-go-live growth
D

Continuous improvement and feature additions

Beyond the initial build, ARIS supports improvement requests and feature additions after systems go live. We prioritize by business impact and deliver in phases to keep systems valuable.

  • Feature additions, UI improvements, and performance tuning
  • Adjustments for business process changes
  • Ongoing support for long-term operations
Use Cases

Typical delivery scenarios

These are not just technical patterns—they reflect common business problems we help clients solve.

New business system build

For teams looking to replace paper-, spreadsheet-, or email-based operations with a centralized web system. We support workflow standardization, input control, access management, and auditability.

Web-enable or API-enable existing workflows

For organizations moving from desktop or on-premise setups to browser-based systems and APIs. We design the architecture with future integrations and reusability in mind.

Phased migration of C# / Java systems

For teams that want to preserve existing business logic while reducing maintenance overhead. We prioritize critical functions first and plan realistic migration paths, including parallel operations where needed.

Business platforms with complex integrations

For integration-heavy projects involving third-party systems, file exchange, batch processing, or centralized authentication. We approach these projects from a whole-system perspective rather than as isolated builds.

Delivery Process

How we work together

From first conversation to long-term operations, each phase has clear inputs, outputs, and control points.

1

Free consultation

Clarify goals, pain points, constraints, and where to start. Duration: 30 minutes.

2

Requirements clarification

Walk through stakeholders, existing workflows, documentation, current issues, and priorities. Duration: 1–3 weeks.

3

Architecture & design

System architecture, screen design, data model, API specs, and delivery plan. Duration: 2–4 weeks.

4

Development & testing

Iterative development with progress reports, issue tracking, code review, and quality checkpoints. Duration: Per sprint/milestone.

5

Deployment & handoff

Final testing, deployment to production, documentation, and knowledge transfer. Duration: Per phase.

Governance

Quality and project governance

We focus on reducing the visibility gaps that often create concern in offshore delivery, so clients can manage progress and quality with confidence.

Clear project coordination

Meetings, documentation, issue tracking, and scope alignment are handled in a structured way to reduce misunderstandings and support smoother decision-making.

Visible progress and control

Tasks, milestones, risks, changes, and issues are shared regularly in a format that both leadership and operational teams can follow.

Quality-gate execution

Reviews, test criteria, acceptance conditions, and release decisions are defined upfront so quality control is consistent and not dependent on individual judgment.

Governance visibility example

We manage more than development, testing, and release—we also cover issues, changes, risk, and operational handover as part of the same delivery flow.

Progress sharingWeekly reports, milestones, risk and issue visibility
