Software Maintenance, UI Redesign & Feature Upgrade

Take over, refactor, redesign and upgrade existing apps and systems

ขอใบเสนอราคาติดต่อทาง WhatsApp

What We Build

We take over, maintain, refactor, and upgrade existing software. We fix bugs, redesign outdated UI, improve performance, add features, and modernize legacy apps, mini programs, and systems.

Suitable Business Scenarios

  • Existing apps that need bug fixes and upkeep
  • Outdated UI that needs a modern redesign
  • Legacy code that needs refactoring or migration
  • Products needing new features and upgrades

Core Features

  • Code audit and takeover
  • Bug fixing and performance tuning
  • UI/UX redesign and modernization
  • Refactoring and framework migration
  • New feature development
  • Ongoing maintenance plans

Tech Stack

We work across Vue, React, Next.js, UniApp, Flutter, Android, iOS, Go, Java, Node.js, Python, MySQL, PostgreSQL, and Redis to maintain and upgrade existing stacks.

Development Process

  1. Requirement & Estimate: we clarify scope, platform, features, and timeline, then send a fixed estimate.
  2. UI/UX Design: wireframes and visual design approved before development.
  3. Development & Integration: iterative builds with payment, maps, SMS, AI, and third-party API integration.
  4. Testing & QA: functional, compatibility, and performance testing across target devices.
  5. Delivery & Deployment: store submission, server deployment, source code handover, and documentation.
  6. Maintenance & Upgrade: ongoing support, bug fixes, and feature upgrades after launch.

Delivery Scope

  • Full source code ownership and Git repository handover
  • UI/UX design files and technical documentation
  • Deployment to your server or app store account
  • Free bug-fix warranty period after launch
  • Optional ongoing maintenance and feature upgrade plan

Planning Notes for Lean Buyers

This service is designed for solo founders, student startup teams, creators, micro businesses and small businesses that need a practical first version instead of a large enterprise build. If you are comparing a software developer for small business, focus on budget control, fixed estimate, source code ownership, launch support and maintenance before adding advanced features.

Recommended First-Version Scope

  • One core user workflow and one admin workflow
  • Backend API, database and admin panel only for the operations you need at launch
  • Source code handover, deployment notes and a clear maintenance path
  • Optional AI, automation, payment or reporting after the first workflow is stable

คำถามที่พบบ่อย

Can you take over an app another team built?

Yes. We start with a code audit, document the current state, and propose a safe plan for maintenance, fixes, and upgrades.

Can you only redesign the UI?

Yes. We can deliver a UI/UX redesign and refactor while keeping your existing backend, or modernize both together.

Can you keep the first version affordable?

Yes. We start with one clear workflow, a fixed estimate, and the features needed to launch. Extra automation, advanced reports, and complex integrations can be added after the first version proves value.

Will I own the source code?

Yes. Delivery can include source code handover, deployment notes, database notes, and documentation so you can continue with Manboo or another developer later.

Can you provide maintenance after launch?

Yes. We can support bug fixes, small feature upgrades, UI improvements, server deployment checks, and future takeover or refactoring work after launch.
