Legacy app modernization for web and mobile apps
Move your ageing web or mobile app to a modern, secure, cloud-ready stack for up to 50% less than it cost to build.* I assess what to keep, rebuild what has to change, and deliver in phases so your business keeps running.

Signs it is time to modernize
If two or more of these sound familiar, your app is probably costing you more to keep than to modernize.
- Every change is slow or risky. Small updates take weeks and fixes break other things.
- Security and compliance worries: unsupported frameworks and old PHP, .NET or Java versions.
- The app is slow and not mobile friendly. Pages take seconds to load and break on phones.
- Hosting and support costs keep rising, with manual deployments and constant firefighting.
- It is hard to find developers who know the original technology.
- It cannot connect to your other tools: no APIs for your ERP, CRM, payments or AI.
Four ways to modernize, and how I choose
There is no single answer. In the free assessment I look at your code, data and goals and recommend the lowest-risk path that gets you there.
| Approach | What changes | Best when |
|---|---|---|
| Rehost | Move the app as it is to modern cloud hosting. | You need a fast, low-risk win and the code is still sound. |
| Refactor | Clean up the code, upgrade the framework and add APIs. | The core logic is good but the framework or structure is dated. |
| Rebuild | Re-architect on a modern stack, reusing your data and business rules. | The technology is obsolete and you want a long-term foundation. |
| Replace | Adopt a ready product and integrate it with your systems. | Custom code adds little value that a standard product cannot give. |
How the modernization works
A phased approach keeps your app running while it is being improved.

Modern stack options
I choose the stack for your goals. MEAN/MERN (MongoDB, Express, Angular or React, Node.js) is a common target for web apps, and Flutter for mobile apps.
How "up to 50% less" works
A large part of any rebuild is rediscovering what the app does. By reusing your existing business rules, data models and documentation, and modernizing in phases, the new build can need much less effort than the original. The actual saving depends on the size, code quality and documentation of your app. That is why I give you a fixed quote after a free assessment, not a guess.
Frequently asked questions
Straight answers to what clients ask before they start.
How long does modernization take?
It depends on the size of the app. A focused web app can take a few months, while larger systems are delivered in phases. After the free assessment you get a roadmap with timings for each phase.
Will I lose my data?
No. Data migration is planned and tested before cut-over, with verification checks, and your original system stays available until the new one is confirmed.
Can the old system keep running during the migration?
Yes. I plan modernization in phases so the business keeps running, and cut over module by module where that makes sense.
What does "up to 50% less" mean?
It means the modernization can cost up to 50% less than it cost to build the original app. The saving depends on your app, so you get a fixed quote after a free assessment.
Which legacy technologies do you work with?
Common examples are older PHP and CodeIgniter apps, .NET and ASP.NET WebForms, Java, Classic ASP, jQuery front-ends, Cordova and Ionic mobile apps, and CMS-based systems. If yours is not listed, ask me.
Do you work with clients outside India?
Yes. I have delivered projects for clients in the USA, UK, Europe, the Middle East and Asia, and I work across time zones.
What do I need to start?
Just book the free assessment. Share what the app does, what hurts most and, if you can, access to the code or a walkthrough. NDA is available on request.
