Reliable Java for systems that cannot go down
- Order, billing and inventory platforms
- Healthcare and assessment back ends
- B2B portals with ERP integration
- High-volume APIs for mobile apps
- Legacy Java EE and Struts modernization
- Batch processing and reporting systems
Ecomsolver is a Java development company working with businesses that need dependable back-end systems: order management, billing, logistics, healthcare records and internal platforms that connect many departments. Java's strong typing, mature tooling and long-term support releases make it a safe choice when downtime and data errors are expensive.
For new builds we use Spring Boot, Spring Security and Spring Data with PostgreSQL or Oracle, packaged in containers and deployed through CI/CD. For existing systems, we upgrade old JDKs, replace outdated application servers and frameworks such as Struts or older Java EE stacks, and break monoliths into services only where it reduces risk or cost.
Every project starts with a free consultation and a written fixed quote, with weekly demos and full code ownership.
Java development services
Every engagement starts with a free consultation and a written, fixed quote.
Spring Boot application development
Business applications and REST or GraphQL APIs built on Spring Boot with Spring Security, Spring Data and clear layering, ready for web, mobile and partner clients.
Microservices architecture
Service design, API gateways, messaging with Kafka or RabbitMQ, and observability with distributed tracing, applied where splitting a system actually improves delivery or scaling.
Enterprise integrations
Connect ERP, CRM, payment, warehouse and identity systems such as SAP, Salesforce, Microsoft Dynamics and Okta using APIs, message queues and scheduled batch jobs.
Java modernization
Upgrade old JDKs to a current LTS release, migrate from Struts or older Java EE to Spring Boot, and replace heavy application servers with containerized deployments.
Performance and reliability fixes
Find memory leaks, slow queries and thread contention with profilers and APM tools, then tune JVM settings, caching and database access for faster, stable performance.
AI features for Java systems
Add LLM-powered search, document processing or assistants to Java applications using Spring AI or direct API calls, with audit logs suitable for regulated environments.
We fix it, fine-tune it, then add AI and automation.
Most clients come to us with something already running: a store that is slow, an app that crashes, code nobody wants to touch. We stabilise it first, then add the AI features that save time and earn money.
Fix
A code and infrastructure audit of your Java product, then the fixes that matter most.
- Bugs, crashes and broken integrations
- Security patches and outdated versions
- Code nobody can maintain
Fine-tune
Make it fast, stable and easy to change, without a risky rewrite.
- Speed, caching and database tuning
- Tests, CI/CD and monitoring
- UX fixes where users get stuck
Add AI & automation
Practical AI built into the Java product you already have.
- AI search and assistants over your own data
- Content, document and support automation
- AI agents that work with your tools
Why choose our Java developers
Stability first
Strong typing, automated tests with JUnit and Testcontainers, and careful release planning keep critical systems stable while they evolve.
Modernize without a big bang
We move legacy Java systems forward in stages, so each step delivers value and the business never depends on one risky cutover.
Security built in
Spring Security, OAuth2, dependency scanning and secure coding practices protect sensitive data, which matters for finance, healthcare and B2B platforms.
Enterprise-ready process
NDAs, documented architecture, code reviews and milestone sign-offs fit the governance requirements of larger organizations and their IT teams.

Java Development: frequently asked questions
Ask us on WhatsApp. A real person replies, usually within minutes during working hours.
Ask on WhatsAppWhat does a Java development company like Ecomsolver build?
As a Java development company, we build Spring Boot APIs, enterprise back ends, microservices, integration layers and batch systems, and we modernize older Java applications. Typical clients run order, billing, logistics or healthcare processes where reliability matters. We also add web or mobile front ends using React, Next.js or Flutter when needed.
Can you upgrade our application from an old Java version?
Yes. We assess your current JDK, frameworks, libraries and application server, then upgrade to a current LTS release in planned steps. That usually involves replacing removed APIs, updating dependencies and adding tests around critical flows. Each step is verified on staging before production, so the system keeps running throughout.
Should we move our Java monolith to microservices?
Not always. Microservices add operational overhead, so we recommend them only when separate teams, scaling needs or release speed justify it. Often a well-structured modular monolith on Spring Boot delivers most of the benefit at lower cost. We explain the trade-offs in writing before you commit to either path.
Do you work with our in-house IT team?
Yes. We often work alongside internal teams, following your coding standards, Git workflow, security policies and change approval process. You get direct access to our developers, shared documentation and regular demos, and our time-zone overlap with the US, UK and Europe keeps collaboration practical.
How is a Java project priced?
After discovery, we send a written fixed quote divided into milestones, or a monthly rate for long-running modernization or dedicated developer work. You pay as milestones are delivered and accepted. Scope changes are estimated and approved before work starts, so the budget stays predictable.
