Spring Boot Developers in the UK

About Spring Boot Developers

Senior backend engineering for Java and Spring Boot: versioned REST APIs, microservices, and system integrations built on Spring Boot 3 and Java 21, with real tests and CI in every build. Hire one dedicated developer, augment your existing squad, or hand us a scoped project, all on a written scope, a flat quote, and code you own from the first commit.

What the engagement includes

• API design that survives contact with real clients: versioned REST, clear error contracts, pagination, idempotency, and OpenAPI docs, the same whether the runtime is Node, PHP, or the JVM.
• Relational and NoSQL data modelling in PostgreSQL, MySQL, MongoDB, and Redis, which maps directly onto Spring Data JPA, Hibernate, and Spring Data MongoDB.
• Automated testing as a default rather than an afterthought: integration tests wired into CI before code merges, which is exactly how JUnit 5 and Testcontainers are meant to be used.
• CI/CD and containers we run every day: GitHub Actions, Docker, and AWS deployments (ECS, EKS, Elastic Beanstalk) that a Spring Boot service drops into cleanly.
• Migrations off legacy systems, which is often the exact reason a team wants a fresh Spring Boot backend in the first place.
• Framework-agnostic security: OAuth2, JWT, role-based access, and secrets management that are non-negotiable from day one on any stack.

Failure to prevent fraud, Bribery Act associated persons and modern slavery statements for a Spring Boot team

Since 1 September 2025 a large organisation can be prosecuted in the UK when someone associated with it commits a fraud intended to benefit it or its clients, unless it proves it had reasonable procedures to prevent fraud. Large means meeting two of three tests across the whole group, more than 250 employees, more than £36 million turnover and more than £18 million in assets, which takes in many of the banks, insurers, retailers and utilities whose back ends are Spring Boot services. The question for an offshore team is whether it is associated, and the Home Office guidance draws a line worth designing the engagement around. A person is associated while providing services for or on behalf of the organisation, judged on all the circumstances, but services provided to the organisation are not the same thing, and the guidance's examples of that are external lawyers, valuers, accountants and engineers. A team writing and testing code to your specification sits naturally on the 'to' side. The line moves when the same team also operates what it builds: runs the monthly billing batch, adjusts a customer's charges through an admin endpoint, produces financial figures or answers customers through a back-office tool. Those are things done on your behalf, and the offences the guidance lists include false accounting and fraud by failing to disclose information as well as fraud by false representation. The offence needs a UK nexus, which a UK customer base supplies even when the act takes place in India. So operational access is scoped separately from development access, every production change touching prices, fees or financial outputs goes through a pull request and a pipeline that records who approved it, and Spring Boot Actuator and admin endpoints are closed to the delivery team in production. That record is the kind of evidence a defence of reasonable procedures rests on. Whether a particular arrangement makes us an associated person is for your counsel.

The Bribery Act 2010 asks the same question in the same words, whether a person performs services for or on behalf of the organisation, decided on all the circumstances, and its section 7 offence of failing to prevent bribery has no size threshold. The only defence is adequate procedures, and the Ministry of Justice guidance, last updated on 22 January 2025, frames them in six principles: proportionality, top-level commitment, risk assessment, due diligence, communication and training, and monitoring and review. It says contractors can be associated persons to the extent they perform services for or on behalf of the organisation, and that where a project runs through a prime contractor and subcontractors an organisation is likely to control only its relationship with its own counterparty, so it should use risk-based due diligence and anti-bribery terms there and ask the counterparty to do the same with the next party in the chain. Two points weigh more heavily for a supplier in India than for one in the UK. The Act has no exemption for facilitation payments, which the guidance contrasts with US foreign bribery law, so a small payment to speed up routine government action is a bribe under UK law wherever it is made. And bribing a foreign public official is an offence in its own right. In a pure development engagement the contact with officials is slight, because our dealings with Indian authorities are for our own business rather than on your behalf. The exception is anything done for your project locally, such as clearing test hardware through customs for an environment hosted in India, or obtaining a registration your procurement team asks for. Those steps belong in the contract, done by the supplier's own staff rather than a fixer and recorded with any cost, and the anti-bribery clause in your supplier terms should flow down to anyone the supplier engages. Whether your procedures are adequate is for your counsel.

If your organisation supplies goods or services, carries on business in the UK and has total turnover of £36 million or more, section 54 of the Modern Slavery Act 2015 requires an annual statement of the steps taken to deal with modern slavery in the business and its supply chains. The Home Office says it must be approved by the board, signed by a director, linked from a prominent place on the homepage of the UK website, and, under statutory guidance, published within six months of the financial year end, and it encourages adding the statement to the government registry. It also notes that reforms to the reporting requirements announced in its consultation response have not yet taken effect. An offshore engineering supplier sits inside that supply chain, and long Spring Boot programmes are where an invisible tier tends to grow. A vendor that wins a large team often fills seats through subcontractors and freelancers, so the people writing your services may not be employed by the company you contracted with, and nobody on your side can see their terms. The statement does not have to claim the chain is slavery-free, but it does have to describe what was done, and the Home Office recommends covering six areas: organisation structure and supply chains, policies, due diligence, risk assessment and management, key performance indicators and training. The supplier's part is to make its row of that statement factual. The terms worth asking for are engineers employed directly by the supplier, subcontracting only with your written approval, and each year the evidence your due diligence section can cite: the headcount on your work by employing entity, confirmation that no engineer paid a recruitment fee, and the hours actually worked, on-call included, since covering UK hours from India is the part of this work most likely to stretch a working day. What goes in your statement is for your board to approve.

How we work with UK clients

UK engagements tend to start with procurement questions rather than technical ones. Who holds the data, which law governs the contract, whether you can produce a record of processing if the ICO asks. We answer those in the proposal instead of leaving them to a legal review three weeks in, because that review is where UK projects usually stall.

Invoicing is the other thing worth settling early. We are outside the UK, so services we supply generally fall under the reverse charge and your finance team accounts for the VAT rather than paying it to us. Our invoices say so explicitly. We quote in pounds, the figure does not move with the exchange rate mid-project, and payment by bank transfer avoids the card fees that make a five-figure invoice unnecessarily expensive.
