WeBuildStack is a remote-first software development company in Bengaluru, India, that builds web and mobile applications and the cloud behind them. For a dedicated Java and Spring Boot engineer you interview first, with a 15-day risk-free trial and a tech lead reviewing every pull request: profiles within 48 hours, a start within one to two weeks, in your timezone. 15+ engineers, 100+ projects.
Java engineers for the systems where a wrong number is an incident: billing, ledgers, order management, core-banking integrations. Spring Boot 3, Kafka, Hibernate, and the habit of writing the test before the fix. They work inside your VPN, your SSO and your change process when that is what the environment requires.
Transaction boundaries in Spring: what @Transactional really covers, and where it silently does not.
Kafka consumer design with retries, dead-letter topics and the trade-offs around exactly-once.
Finding an N+1 query in Hibernate and fixing it without rewriting the repository layer.
Securing a microservice with Spring Security, OAuth2 scopes and method-level rules.
The four ways to add a Java engineer, stated fairly. The figures in our row are the ones every page on this site commits to.
| Channel | Time to start | Who reviews the code | Continuity | Trial | Management load |
|---|---|---|---|---|---|
| Marketplace freelancers (Upwork, Fiverr) | Days | Nobody unless you arrange it | One person; no replacement | Per contract | You manage everything |
| Vetted-talent networks (Toptal, Lemon.io) | Days to a week | Your lead | Replacement by the network | Usually a trial period | You manage the work |
| Dedicated-team companies (WeBuildStack and others like us) | Profiles in 48 hours; start in one to two weeks | A tech lead reviews every pull request | Replacement guarantee; no minimum term | 15-day risk-free trial | Shared: you direct the backlog, the company handles HR, quality and replacement |
| In-house hire | Months | Your lead | Highest | Probation | Everything, including recruiting |

Completes access provisioning, builds the service with Maven or Gradle and runs it against your test environment.
Fixes a real defect test-first: a failing JUnit case, then the change, then a green pipeline.
Maps the service’s dependencies, timeouts and circuit breakers, and names the riskiest integration point.
Something not covered here? Ask a tech lead. We reply within one business day.
Yes, for a dedicated Java and Spring Boot engineer you interview first, with a 15-day risk-free trial and a tech lead reviewing every pull request. Profiles within 48 hours, a written monthly rate with them, a replacement guarantee, no recruitment fees and no minimum term; the engineer works in your repositories, stand-ups and hours from Bengaluru, India.
Yes. Our Java engineers are used to VDI access, no-local-code policies, SSO-only tooling, change-advisory boards and audit trails for every merge. Background checks and your NDA are completed before access is provisioned. All code and records stay in your systems.
Yes. Several of our engineers have moved Java 8 monoliths on WebLogic or JBoss onto Spring Boot and Kubernetes using the strangler-fig approach, keeping the old path live until the new one has passed the same fixtures.
Usually within 3 to 7 working days once VDI, VPN and background checks are complete. You interview the shortlisted Java engineers; nobody is assigned without your approval.
The 15-day clock starts when access works, not when the contract is signed. If the engineer is not a fit in that window you pay nothing for it and we replace them or part ways. No lock-in.
Java engineers stay on the backend. When you need the UI as well, we add a React or Angular engineer to the pod under the same tech lead so the API and the screens ship in the same sprint.
What arrives within 48 hours: two or three matching profiles with code samples, each engineer's availability and earliest start date, and a written monthly rate. You interview before anyone starts.
