Java & Spring Boot Development
WeBuildStack is a remote-first software development company in Bengaluru, India, that builds web and mobile applications and the cloud behind them. For a transactional Java 21 and Spring Boot backend, Kafka pipelines and enterprise integrations: a written quote within 48 hours and an MVP in six weeks with deployment included, with team hours set to your timezone. 15+ engineers, 100+ projects.
When a wrong number in a ledger is an incident and not a bug, we build on Java. Week one delivers a Spring Boot skeleton with Spring Security wired to your identity provider, a Flyway migration baseline, a Kafka or RabbitMQ topic plan, and a pipeline that builds, tests and deploys to your staging cluster. From there we add services in the order your domain dictates.
We build the whole stack. MVP in 6 weeks, deployment included.
What you get
- Spring Boot 3 services with Spring Security, OAuth2 resource servers and method-level authorisation
- Event-driven designs on Kafka or RabbitMQ with the outbox pattern, so a database write and its event never disagree
- JPA and Hibernate on PostgreSQL, Oracle or SQL Server, with query plans reviewed before release, not after the outage
- Java 8 and 11 to Java 21 and Jakarta EE modernisation, module by module, with the old and new paths tested against the same fixtures
- Micrometer, Prometheus and Grafana dashboards shipped with every service, plus alerts tuned to your SLOs
How a typical Java project runs
- Week 1
01Scope and quote
A technical lead reads your brief, asks the awkward questions and sends a written Java quote within 48 hours.
- Weeks 2 to 5
02Build in weekly sprints
A demo every Friday. The tech lead reviews every pull request before it merges, and you can see the repo at any time.
- Week 6
03Launch, deployment included
We deploy to your cloud accounts, hand over the repos and a runbook. You own the code and the IP.
Where this service fits
- 01
Core platforms
Order management, billing, ledgers and workflow engines with transactional guarantees you can describe to an auditor.
- 02
Modernisation
Strangler-fig migration of a legacy monolith into services, with a risk register, a traffic-shifting plan and a rollback for every step.
- 03
Integration hubs
Adapters for SAP, Oracle, core banking and partner APIs, each with circuit breakers, retries and a dashboard showing what is flowing.
Where we use Java most
Java & Spring Boot Development: common questions
Something not covered here? Ask a tech lead. We reply within one business day.
Yes, for a transactional Java 21 and Spring Boot backend, Kafka pipelines and enterprise integrations. A written scope and fixed quote within 48 hours, an MVP in six weeks with deployment included, a tech lead reviewing every pull request, and code you own; the team works in your timezone from Bengaluru, India.
Mostly. We pair Spring Boot backends with React or Angular front ends, built by our own front-end engineers in the same sprint. That gives you one team for the whole stack and no hand-off gap between API and UI.
Yes. We work under your NDA, on your VPN or VDI, with your SSO and your audit logging. Code review history, access logs and change records stay in your systems, so your compliance team has the evidence it needs without asking us for it.
The repositories, Helm charts or Terraform for the deployment, Flyway migration history, the JUnit and integration suites, Grafana dashboards as code, and an operations runbook. Deployment to your Kubernetes or cloud environment is part of every project.
