Java Development in Singapore

No GST is charged on our invoice, and the invoice says so. Whether you account for it under reverse charge depends on your input tax position: IRAS's guidance is that a GST-registered business making only taxable supplies is not impacted, a partially exempt business or one with non-business receipts accounts for GST on imported services in its own return, and a business that is not registered should ask its accountant, because an exempt business importing more than S$1 million of services in a year can be required to register. We would rather your accountant confirmed your position before the first invoice than reconciled it at year end.

We build to it rather than claiming a certificate. The consent, purpose limitation and notification obligations shape the forms and the data model; retention limitation means records are deleted on a schedule rather than kept indefinitely; access and correction requests are features with a queue behind them rather than a manual database job. Processing happens in India, so the transfer limitation obligation applies, and the processor agreement we sign sets out the comparable standard of protection the Act asks for. The obligation to design for early is breach notification: an organisation has three calendar days from determining a breach is notifiable, which means one likely to cause significant harm or one affecting 500 or more people, to tell the PDPC, and answering what was in the breach is only possible if the logging existed beforehand. Appointing a Data Protection Officer is your obligation rather than ours, and we will say so if a design choice would make that person's job harder.

Not PSG. The Productivity Solutions Grant funds pre-scoped packages from pre-approved vendors for Singapore-registered companies, and a custom build from an overseas team is not that shape, so we will not pretend it is. The Enterprise Development Grant is assessed project by project against its own criteria, and whether a build like yours qualifies is a question for Enterprise Singapore or your grant consultant to answer before the scope is written rather than after a budget has assumed it.

We can supply what a due-diligence pack asks for, accept audit and access rights in the contract, and name every sub-processor that touches your data. What we will also tell you in the first conversation is what we do not hold: we are not SOC 2 or ISO 27001 certified, and our security page says so in those words. Whether an engagement with us is a material outsourcing arrangement under the MAS guidelines, and what that requires of you, is your compliance team's determination, and it changes the contract before it changes the code, so it belongs in week one.

We are straight about this: Java is a service line we take on, not the stack most of our shipped work runs on. Since 2021 we have delivered 70+ projects in total, with the bulk in Node.js, TypeScript, and PHP rather than Java. What we bring to a Java build is senior engineering discipline that transfers directly, REST API design, testing, CI, and the PostgreSQL and AWS work we do every week, plus a promise not to bill you for learning basics on the job. If your project needs deep JVM specialists we are not, we will tell you.

Spring Boot for the application, Spring MVC for REST, Spring Data JPA with Hibernate over PostgreSQL, and Spring Security with JWT or OAuth2 for auth. We build with Maven or Gradle, test with JUnit 5, Mockito, and Testcontainers, document APIs with OpenAPI, and deploy Docker containers to AWS with CI running on every push. We target current LTS Java, 17 or 21, and can work in older versions when an existing codebase requires it.

It depends on your situation, and we will give you an honest read rather than push the one you searched for. Java is the stronger pick when you already run on the JVM, are in an enterprise setting that standardizes on it, or are building a large, long-lived backend that many engineers will share. Node.js with TypeScript, which is where our deepest experience sits, usually gets a smaller product or MVP live faster and cheaper. Tell us the project and we will tell you which one we would actually choose.

Yes. That is most of the Java work we are asked for: Spring Boot REST APIs, documented with OpenAPI and secured properly, integrated with payment gateways, ERP or CRM systems, message queues like Kafka and RabbitMQ, and third-party REST or SOAP endpoints. We build in the retries, timeouts, and error handling that integrations need to survive real traffic, not just the happy path in a demo.

Yes, carefully. We migrate ageing Java EE, Struts, or old-Spring monoliths onto current Spring Boot and a supported LTS Java, one tested slice at a time, so the running system stays up while it moves. Before we pile features onto an inherited codebase we are honest about its state: if it needs a test harness or a cleanup pass first, we will say so rather than build new code on a shaky base.
