We Take Over the Software Your Business Runs On

NUS Technology is a Vietnam-based software engineering firm founded in 2013. With 70+ engineers, we take over existing codebases, extend the platforms businesses rely on, and provide the ongoing engineering support needed to keep software reliable and evolving.

Most clients come to us after a developer left, an agency went quiet, or nobody wants to touch the code anymore. Taking over existing software is our core business, not a side service: legacy Rails, PHP and Node.js systems, inherited codebases with no documentation, and AI-built apps (Lovable, Bolt, Replit, Cursor, v0) that work as prototypes but aren't safe for real users.

Three services: Take Over & Stabilize, Run & Maintain (monthly plans with a named technical lead), and Extend & Integrate (custom features and integrations on Shopify, Mindbody, Stripe, CRMs, ERPs and hardware). We also offer dedicated teams and new builds.

How to start: a free assessment. A senior engineer reviews your code, hosting and security and sends a written report within 5 business days, no obligation. The first 2 weeks of every takeover are risk-free: if you're not happy, you don't pay.

Some of our partnerships have lasted 5–12 years. You own all code, repositories and cloud accounts from day one.

Our Story

NUS Technology started in Ho Chi Minh City in 2013 as a small team of Ruby on Rails engineers. Over the years, more and more clients came to us with software someone else had built and left behind. Taking over that software, making it stable and keeping it running became what we do best. Today our 70+ engineers look after platforms for companies across the US, UK, Europe and APAC, some for more than ten years.

What Sets Us Apart

Takeover is our core business

Most clients come to us after a developer left, an agency went quiet, or nobody wants to touch the code. We take over software others built or walked away from, including AI-built apps, then stabilize it first and improve it step by step while your business keeps running.

A free assessment, with no obligation

Before you commit to anything, a senior engineer reviews your code, hosting and security and sends a written report within 5 business days. You get the system's health, the top risks ranked by business impact, and recommended next steps. The report is yours to keep, even if you choose another team.

The first 2 weeks are risk-free

Every takeover starts with two risk-free weeks. By day 10 you have monitoring, documentation, a shipped improvement and a 90-day plan. Not happy? Tell us by day 10 and you pay nothing. You keep everything we produced, and you own your code and accounts from day one.
