Spring Boot Developers 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.

Spring Boot is a newer service line for us, and we say so plainly. Our daily backend work is Node.js and Laravel/PHP on PostgreSQL, MongoDB, Redis, and AWS. The transferable part (API design, data modelling, automated testing, CI/CD, and security) is core to how we already work, and the JVM-specific depth comes from vetted Spring Boot specialists our senior team screens and reviews. If your project truly needs a deep, long-standing Spring Boot house with a big Java bench, we will tell you that honestly rather than take the work and learn on your budget.

Senior JVM and Spring Boot rates in India typically run about S$11to S$62per hour depending on seniority and scope, and a full-time dedicated developer usually starts around S$1,100per month, higher for senior architects. For defined work (a new API, a service to extract, an integration) we quote a flat INR figure with GST included, paid against milestones, so there are no hourly surprises. International clients are quoted the equivalent in USD, GBP, CAD, or AED.

Choose a fixed-price project when the backend scope is clear and you want a known number and a known date. Choose a dedicated developer when the roadmap is still moving and you want to direct the work sprint by sprint on a rolling monthly contract you can stop anytime. Choose staff augmentation when you already have a team and a tech lead and just need vetted hands inside your process. Many clients start with a small fixed-price build to test the working relationship, then move to a dedicated developer or augmentation once they trust the output.

Every engineer clears a live coding and system-design screen with our senior team plus a hands-on Spring Boot task, not a quiz, before you ever see them. You then interview the shortlist yourself and pick who joins. Once they start, our lead reviews their pull requests as a standing backstop, so the code-review and testing bar is the same one we hold on our own projects. The person you interview is the person who does the work, no substitutions after you sign.

New work defaults to Spring Boot 3.x on Java 21 LTS, with Kotlin where you prefer it, Spring Data JPA and Hibernate for the data layer, Flyway or Liquibase for migrations, and Spring Security with OAuth2 and JWT. Builds run on Maven or Gradle, ship in Docker to AWS, and use JUnit 5 with Testcontainers for tests. We will happily maintain or upgrade an existing Spring Boot 2 or Java 8/11 system, but we do not start fresh projects on end-of-life versions unless there is a hard constraint forcing it.
