Colan Infotech develops Java-based web, mobile backend, and enterprise applications for businesses that require stable architecture, secure data handling, system integrations, and long-term maintainability. Our Java team works on new application development, modernization of existing platforms, backend services, API development, microservices, and integration with enterprise systems.
Our Java Development Services
Java Enterprise Application Development
Development of business applications, internal portals, operational platforms, and transaction-based systems using Java and modern enterprise frameworks.
Spring Boot Development
Backend application development using Spring Boot for business logic, REST APIs, authentication, database operations, integrations, and scheduled processes.
Microservices Development
Design and development of independently deployable services with clear service boundaries, API communication, logging, exception handling, and event-based processing.
REST API Development and Integration
Development and integration of APIs for web applications, mobile apps, third-party platforms, payment systems, enterprise software, and internal services.
Legacy Java and J2EE Modernization
Review and modernization of older Java or J2EE applications, including framework upgrades, code restructuring, API enablement, dependency updates, and migration to Spring Boot-based architecture.
Event-Driven Application Development
Implementation of asynchronous workflows, messaging, and data processing using technologies such as Apache Kafka.
Database Integration and Optimization
Java application integration with relational and NoSQL databases, including data modelling, indexing, query handling, aggregation, and performance review.
Application Support and Enhancement
Ongoing work within existing Java codebases covering feature development, defect resolution, performance improvement, integration changes, testing, and deployment support.
Before confirming the scope, we review the current application or workflow, Java and framework versions, architecture, database structure, integrations, deployment environment, and the business-critical flows that must remain unaffected.
