What We Build
Java Development Services
From greenfield product engineering to large-scale modernization, our Java teams deliver production systems that handle real load and stay maintainable for years.
Production-ready web applications, REST and GraphQL APIs, and event-driven backends built on Spring Boot, Jakarta EE, and the modern JVM stack.
Java Expertise
Java Core Competencies
Senior engineers with deep command of the Java ecosystem, from JVM internals to the frameworks and tools that power production systems at scale.
Production Stacks
Java Stacks Running in Production
Reference architectures we use to start projects fast. Each stack is opinionated, documented, and tuned for the workload it serves.
Spring Boot REST API with Relational Database
Battle-tested stack for transactional web services. Spring Boot REST controllers, Hibernate persistence on PostgreSQL or MySQL, JWT auth, OpenAPI docs, and Flyway migrations.
Reactive Java with Spring WebFlux
Non-blocking, high-concurrency apps for streaming, real-time dashboards, and chat. Spring WebFlux on Netty with Project Reactor, R2DBC for reactive data access, and Redis pub/sub.
Event-Driven Microservices with Kafka
Spring Cloud microservices communicating over Apache Kafka, with schema registry, dead-letter queues, and exactly-once semantics for high-throughput pipelines.
Serverless Java on AWS Lambda
GraalVM native images for sub-100ms cold starts. Spring Cloud Function on AWS Lambda, with DynamoDB or RDS for state and API Gateway for routing.
Search and Analytics with Elasticsearch
Spring Boot apps backed by Elasticsearch for full-text search, log analytics, and observability. Logstash pipelines and Kibana dashboards included.

Testimonials
Words from Our Clients
Discover how our expert solutions empower businesses and delight customers.
Angular Minds helped us turn an idea into a fully functional FinOps platform. Their ability to move fast, execute with precision, and collaborate as true partners allowed us to launch quickly and start generating revenue. They are sharp, capable, and a pleasure to work with.
Since 2016, we've been in a great partnership with Angular Minds, and I feel truly lucky to have their team by my side. Together, we've created an insurance platform that automates the entire insurance process - from Quoting to Policy Binding, Renewals, and Payments. Thanks to the hard work of the entire team, we've successfully onboarded over 30 insurance companies onto our platform. Kudos to everyone involved!
How We Work
Java Development Process
A predictable rhythm that gets your team productive fast and keeps stakeholders informed every sprint.
Workshop to map domain, dependencies, and non-functional requirements. Output: architecture decision records, tech stack recommendation, sprint plan.
Senior engineers onboard in days. Repos cloned, environments running, and working code delivered from the first iteration.
Two-week sprints with demos, retros, and code reviews. CI runs on every PR with unit, integration, and security checks.
Performance testing with JMeter or Gatling, security audit, observability setup with Prometheus and Grafana, and a staged production rollout.
Post-launch SRE support, on-call coverage if required, and a roadmap for the next quarter of feature work and platform investments.

FAQ
Questions Asked About Java
Do you still have any questions, let us know. We would be happy to assist.
- Java 21 is the recommended LTS version for new projects. It includes virtual threads, pattern matching, record types, and sealed classes. Java 17 remains a solid choice for teams that prefer a longer track record. Both receive long-term security updates from Oracle and the OpenJDK community.
- Modular monoliths suit early-stage products where speed of iteration matters more than independent deployability. Microservices make sense when the codebase has clear domain boundaries, multiple teams need to release independently, or traffic patterns require scaling specific services. Most projects start as monoliths and decompose later.
- The standard approach is a strangler-pattern migration: wrap the legacy system behind new APIs, rewrite modules one at a time in Spring Boot or Jakarta EE, and route traffic incrementally. This allows continuous releases without freezing feature work. Common targets include Java 6/7/8 to Java 17/21 and EJB to Spring Boot.
- Spring Boot is the most widely used Java framework for building production-ready web applications and microservices. It provides auto-configuration, embedded servers, health checks, and metrics out of the box, reducing setup time from days to minutes. It integrates with Spring Security, Spring Data, and Spring Cloud for enterprise requirements.
- Rates vary by seniority and engagement model. Staff augmentation with senior Java engineers typically costs less than building an in-house team when accounting for recruitment, benefits, and infrastructure. Fixed-scope and dedicated-squad models offer predictable monthly costs. A discovery workshop helps scope the right team size before commitment.
- Java applications deploy to AWS (ECS, EKS, Lambda), Azure (App Service, AKS, Functions), and GCP (Cloud Run, GKE). Spring Boot apps containerize with Docker, deploy via CI/CD pipelines, and run on Kubernetes for orchestration. GraalVM native images reduce cold-start times for serverless deployments.
- Mandatory pull request reviews, automated test suites (JUnit 5, Mockito, Testcontainers) on every commit, static analysis with SonarQube or SpotBugs, and dependency vulnerability scanning with OWASP Dependency-Check. Coverage targets are typically 70%+ on business logic with integration tests against real databases using Testcontainers.
- Yes. Java remains one of the most widely deployed server languages, and recent releases have kept it competitive: virtual threads in Java 21 make high-concurrency services far simpler to write, and GraalVM native images cut cold starts for serverless. Combined with the maturity of Spring Boot and a deep hiring pool, it stays a safe, long-lived choice for systems meant to run for a decade.
- Take a single senior Java engineer or a full managed squad, depending on what you are missing. The team works from your existing repos, CI, and review process, and scales as the project grows or winds down.
- Timelines track the domain, not the language. A focused Spring Boot service ships in a couple of months; a large system carrying legacy integrations and compliance rules takes longer to get right. Work runs in two-week sprints against a staging environment, so you can watch it come together the whole way rather than at the finish line.
