Modernization & migration · Singapore
Application modernization services in Singapore
A senior team a short time-zone hop away, building products ready to scale across the region.
Clarigo Infotech modernizes and migrates legacy applications so they are secure, fast and easy to change again: PHP upgrades and migrations to modern stacks, Java 8 to Java 17 or 21 with current Spring Boot, .NET Framework to modern .NET, and monoliths split into services where it genuinely helps. We migrate step by step behind a safety net of automated tests, so your business keeps running while the software underneath gets better.
Singapore companies most often hire us for fintech, logistics and AI products for Southeast Asia.

What we modernize and migrate
PHP upgrades and migration
Old PHP 5 and 7 apps upgraded to PHP 8, or moved to Laravel, Symfony, Node.js or another modern stack.
Java modernization
Java 8 to Java 17 or 21, Spring to current Spring Boot, javax to jakarta, and old app servers to containers.
.NET modernization
.NET Framework and Web Forms to modern .NET, ASP.NET Core and cross-platform hosting.
Monolith to microservices
Split a large codebase into well-defined services, one piece at a time, only where it improves speed or scale.
Front-end modernization
jQuery, AngularJS and server-rendered pages rebuilt in React or Next.js with a modern, accessible UI.
Cloud-native refactoring
Containers, managed databases, queues and serverless, so the app scales and costs less to run.
How we approach Modernization & migration
Why modernize now
Unsupported language versions stop getting security fixes, hosting gets harder, and every new feature takes longer than it should. Modernizing removes that risk and makes the software cheaper to change, without throwing away the business logic that already works.
Rewrite or refactor?
A full rewrite is rarely the safest path. We assess the code and usually recommend an incremental approach: upgrade what can be upgraded, replace the parts that block you, and keep everything that still works. You get a clear recommendation and cost for each option.
No big-bang switchover
We put automated tests and monitoring around the existing system first, then migrate in small, reversible steps, often running old and new side by side. Your users keep working, and every step can be rolled back.
Documented and handed over
You get updated documentation, a CI/CD pipeline and a codebase your own team can maintain. The same engineers can stay on for support and new features.
Remote, but close to Singapore
Time-zone overlap
Singapore is two and a half hours ahead of India, so our working days overlap for most of the day, with same-day calls and replies.
The Personal Data Protection Act (PDPA)
We design to the PDPA: consent, purpose limitation, protection and retention rules, with data hosted in Singapore cloud regions when required and NDAs signed before work starts.
Billing
Invoices in Singapore dollars (SGD) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Where we help Singapore businesses most
Singapore businesses use us to build fintech, logistics and AI products for the region, with English-speaking senior engineers, close time-zone overlap and data handled in line with the PDPA.
Finance and wealth
MAS-regulated firms build digital banking and wealth platforms. Apps for customers, staff and partners, built on one codebase.
Logistics and shipping
Port and transhipment hub needs tracking and optimisation. We design and ship iOS and Android apps for teams in this sector.
Regional HQs
Companies run Southeast Asian operations from Singapore. Customer and field apps are where we usually start here.
Biomedical sciences
Research and medtech firms adopt AI and data tooling. Apps for customers, staff and partners, built on one codebase.

How it works
1. Free assessment
We review your code, dependencies, infrastructure and data, then give you a written migration plan, risks and a fixed quote.
2. Plan and safety net
We add automated tests and monitoring around what exists today, so every change can be checked against the old behaviour.
3. Migrate in small steps
Module by module, with both versions running side by side where needed. You see progress in a demo every week.
4. Cut over and support
A planned switch-over with a rollback path, then the same engineers stay on to fix, tune and keep it current.

What time-zone overlap do we get from Singapore?+
Singapore is two and a half hours ahead of India, so our working days overlap for most of the day, with same-day calls and replies.
How do you handle the Personal Data Protection Act (PDPA)?+
We design to the PDPA: consent, purpose limitation, protection and retention rules, with data hosted in Singapore cloud regions when required and NDAs signed before work starts.
Which currency do you bill in, and what does it cost?+
We bill in Singapore dollars (SGD) or US dollars. Senior engineers typically cost $25 to $49 (USD) per hour, and fixed-scope projects such as an MVP in 25 to 30 days are quoted after a free consultation.
Where will our data be hosted?+
Usually in AWS Asia Pacific (Singapore), Google Cloud asia-southeast1 and Azure Southeast Asia, or wherever your data rules require. Everything runs in your own cloud account, so you stay in control.
Can you integrate PayNow or GrabPay?+
Yes. We regularly integrate local payment methods such as PayNow, GrabPay, Stripe, Visa and Mastercard, Atome, alongside card payments and subscriptions.
Do you support WhatsApp?+
Yes. Customers in Singapore often prefer WhatsApp and Telegram and LinkedIn, so we connect chatbots, notifications and support flows to them.
How long does a modernization project take?+
A focused upgrade (for example one PHP or Java application) often takes a few weeks to a few months, depending on size and test coverage. You get a timeline and fixed quote after a free assessment.
Do we have to rewrite everything?+
Usually not. Most projects are a mix of upgrading, refactoring and replacing only the parts that block you. We recommend the lowest-risk path for your situation.
