HIRE DEVELOPERS / JAVA DEVELOPERS
High-throughput APIs, financial systems, distributed microservices handling millions of transactions reliably — that's what Java powers at the demanding end of enterprise backends. Our Java development work is production Spring Boot applications with proper architecture, not tutorial-level CRUD apps dressed up as enterprise software.
Modern Java 17/21, Spring Boot for REST APIs and microservices, Spring Security for authentication and authorisation, Hibernate and JPA for database access, Maven or Gradle for build management — the enterprise Java development our developers work in daily. Dependency injection, aspect-oriented programming, transaction management, and event-driven architecture with Kafka or RabbitMQ.
Spring Boot auto-configuration internals, JPA N+1 query detection, JVM garbage collection tuning, transaction propagation boundaries, and real experience shipping Java services handling thousands of requests per second — vetted for enterprise Java depth.
Java developers are the largest programming talent pool in enterprise. Developers who understand microservice boundaries, can tune JVM memory, and have shipped distributed systems with proper observability are a smaller subset than the pool size suggests. We keep them ready.
A dedicated developer for a long-term enterprise platform. A part-time specialist for Spring Boot version upgrades and performance tuning. An hourly consultant for a JVM profiling session or a microservice architecture review. Sized to fit.

Knowing Spring Boot isn't enough for enterprise Java development. Connection pool tuning, JVM memory management, transaction boundaries, proper exception handling hierarchies, and structuring a codebase 10 developers can work in simultaneously without stepping on each other — our developers have worked in real enterprise Java environments where these things actually matter.
One Java developer, embedded full-time, owning service architecture, writing Spring Boot APIs, managing database migrations, and shipping to production. Right for teams building or maintaining enterprise backend systems over multiple quarters.
Contact us for pricingTwenty hours a week of focused Java work — enough for upgrading from Java 11 to 21, migrating a monolith to microservices incrementally, adding features to a stable enterprise application, or improving test coverage on critical services.
Contact us for pricingA JVM heap analysis, a Spring Boot performance audit, a microservice boundary assessment, a Kafka consumer lag investigation, or a Hibernate query optimisation — targeted Java consulting, scoped and delivered.

Service architecture, Spring Boot development, database design, and the CI/CD and deployment pipeline — all ours end to end. You review weekly and steer the product roadmap.
Your engineering lead sets priorities. Our Java developer joins your Jira, your Slack, your standups. They write services and handle deployments through Docker and Kubernetes — you direct the architecture.
Product decisions and frontend stay with your team. API design, the service layer, database access, Kafka integration, and JVM tuning become ours.
Enterprise Java ecosystem expertise — what our engineers actually work with, daily.
Modern LTS with records, pattern matching, and virtual threads.
REST APIs, auto-configuration, and production-ready defaults.
DI, AOP, and core enterprise application context.
OAuth2, JWT, and role-based API protection.
Repositories, specifications, and query methods.

CEO, Modestly
Entalogics has successfully delivered extension prototypes on time, and we are impressed with their project management and the finished product. The client communicates with Entalogics via virtual meetings, email, and messaging apps.
Founder, Flourish Schools
Collaborating with Entalogics was a great experience. Communication was clear, we aligned quickly, and their team delivered high-quality code on time with thoughtful technical decisions.
CTO, SentryBay
Their Chromium expertise helped us ship a hardened browser with live threat controls and enterprise rollout support. Security operations became significantly faster.
Founder, G3 Ventures LLC
Entalogics delivered our custom Electron browser in six months with isolated profile workflows and stable policy sync. Agent onboarding improved by 55% after rollout.
Project Manager, Sociall
Entalogics built our iOS Chromium-based mobile app with a smooth native feel, stable media rendering, and reliable sync. We shipped faster and improved engagement after launch.
RozmeriGPT
The web dashboard and Chrome extension now share prompts, billing, and analytics in one platform. Our content turnaround improved 4x after launch.
Project Manager, Omni Browser
Entalogics built our Omni Browser on top of Chromium with deep product-level execution. They implemented an integrated VPN and Omni Crypto Wallet directly in the browser, made strong architectural decisions, and delivered quality code on schedule with clear communication.
Project Manager, Digital Office: Aura
Entalogics built Digital Office: Aura as a custom Chromium-based authentication platform. Their team modified Chromium internals and integrated our manual custom authentication flow with reliable implementation, fast delivery, and consistent communication.
