Who Is This For?

This service is for businesses that need a partner who not only codes, but understands the business, fits into operations and can accompany them long-term.

1

Current systems are old and hard to maintain or extend

ANSOL helps leverage existing C# or Java assets while gradually migrating to web, API and cloud. We prioritize risk-reduction roadmaps with minimal disruption to operations.

2

Complex requirements that need a partner who understands the business

ANSOL supports requirements clarification for workflows like proposal/approval, sales, inventory, membership, contracts, reports, notifications and permissions. We focus on real operational fit, not just functional design.

3

Quality and governance matter, not just cost

ANSOL makes progress, issues, change requests and quality traceable and transparent. Suitable for businesses that need a team that is easy to manage, coordinate and delegate to long-term.

4

Want to hand off development, operations and continuous improvement together

After go-live, ANSOL can continue with additional development, incident response, performance optimization and SLA maintenance. The goal is stable operations and long-term growth, not just project completion.

What ANSOL Can Support

Depending on business challenges and operational requirements, ANSOL can support the following areas comprehensively.

A

Core Operations Platform

Business Web System Development

ANSOL builds business web systems for sales management, inventory, membership, contracts, proposals/approvals and internal workflows. Design considers real operational needs including permissions, audit logs, notifications, search, reports, CSV import/export, multi-language and timezone.

  • B2B admin panels, portals and back-office
  • Forms, search, lists, approvals, notifications, reports
  • Design prioritizing maintainability and extensibility
  • Supports complex integrations
B

Extensible Integration Layer

API Development & System Integration

ANSOL supports integration with ERP, CRM, accounting, payments, email, Zalo/LINE, SFTP, CSV, Webhook and other external systems. Also implements PHP/Laravel business APIs, REST APIs, auth/authorization, batch/jobs, async processing and integration error handling.

  • REST API / Webhook / SFTP / CSV
  • OAuth2 / OIDC / SSO support
  • Job, batch and async processing design
  • Prioritizes phased migration
C

Incremental Refactoring

Legacy System Modernization

Rather than replacing the entire legacy system at once, ANSOL prioritizes incremental refactoring to minimize operational disruption. We analyze code, data and current operations, then migrate module by module toward a more maintainable and sustainable architecture.

  • Migrate C# desktop apps to Web/API
  • Java refactoring, API-ification and phased migration
  • Review existing data, reports and batch processes
  • Continuous support after go-live
D

Post-Launch Development

Continuous Improvement & Feature Additions

Beyond the initial development phase, ANSOL supports improvement requests and feature additions after the system goes into operation. We prioritize by business impact and deploy in phases so the system continues to deliver value.

  • Post-launch UI improvements, feature additions and performance
  • Adjustments for business changes
  • Continuous long-term operations support

Representative Development Cases

ANSOL not only provides technology but solves real operational problems for businesses.

Building New Business Systems

Suitable when the business wants to replace paper, Excel or email-based operations with a centralized web system. ANSOL also supports process standardization, input rules, permissions and audit requirements.

Web-ification / API-ification of Existing Operations

Applies when moving desktop or on-premise systems to browser or API. Architecture is designed for easy future integrations and reuse.

Phased Migration of C# / Java Systems

Suitable when the business wants to leverage existing logic while improving maintainability. ANSOL prioritizes migrating critical parts first and proposes a roadmap compatible with parallel operations.

Building Operations Platforms with Complex Integrations

Suitable for projects requiring connections to multiple external systems, file transfers, batch processing or centralized authentication. ANSOL looks at the full picture to optimize structure and clarify responsibility boundaries.

Per phase

Quality & Project Governance

We focus on closing visibility gaps so businesses can manage progress and quality with confidence.

Clear Project Coordination

Meetings, documentation, issue tracking and scope adjustments are handled structurally to minimize misunderstandings and speed up decision-making.

Transparent Progress Control

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

Quality Control via Gates

Review criteria, acceptance conditions and release decisions are defined upfront for consistent quality management.

Project Governance Example

We manage more than just development, testing and releases — issues, changes, risks and operations handover are treated as a continuous flow.

Requirements / Issue management Requirements clarification, issue tracking, change requests, prioritization
Quality management Review, test design, bug management, acceptance preparation
Progress sharing Weekly reports, milestones, risk/issue visibility
Operations handover Runbook, maintenance plan, improvement backlog, continuous support
