Java Software Development Services
Can your Java stack survive a 10x user spike?
Java is the core of modern business software—from banking platforms to booking engines. It is known for reliability, security, and cross-platform support, Java is the foundation behind millions of enterprise-grade applications. Java still remains one of the smartest choices if you’re building a scalable backend system, high-performance service, or large-scale business platform.
We specialise in Java software development for backend systems, enterprise applications, internal business tools, and cloud-native services. Whether you’re launching a new platform or improving an existing one, we build Java-based solutions that are stable, secure, and built to handle high scale / volume of users.
Many of our clients come to us when things start to break at scale—slow database queries, GC pauses causing downtime, or legacy Java EE systems blocking growth. We solve these problems through targeted interventions: optimising GC settings with G1/ZGC, breaking up monoliths into Spring Boot or Quarkus microservices, and fine-tuning Hibernate and database layers for faster response times.
We also modernize delivery pipelines—using GitLab CI/CD, Docker, and Kubernetes to ship features safely, with zero-downtime deployments.
If your business depends on a Java-based system—or you’re planning to build one—we help you do it right. Fast, stable, and ready for scale.
Here’s what that looks like in real numbers:
Under 100ms

Make Your Java Stack - Work For You, Not Against You.
Codewave’s Java software development services are built for performance. We deliver clean, scalable code with 100% security patches and a sharp focus on real-world efficiency. You get faster builds, stronger uptime, and zero surprises.
When performance bottlenecks or manual workarounds start draining time and confidence, it’s often a sign your core systems need an overhaul. We build enterprise-grade Java applications that streamline operations, automate decisions, and scale with your growth.
We design backend engines that stay resilient—Real-time payments, supply chain visibility, or customer onboarding—even under unpredictable loads.
Using Spring Boot, async job queues, and modular hexagonal architectures, we build apps that are fast, secure, and easy to extend.
We also integrate JWT-based auth, rate limiters, and observability hooks—so you’re not just moving faster, but with full control and visibility across systems.
Example: A digital lending platform rolls out a fully automated loan origination system using Spring Boot, async workflows, and JWT-based access control—enabling real-time bureau checks, fraud detection, and under-2-minute loan approvals at scale.
Monolithic systems slow everything down—whether it’s shipping new features, recovering from outages, or scaling under pressure. We help you move fast again by decomposing legacy platforms into modular, Java-based microservices using Spring Boot or Quarkus.
Each microservice runs independently, with its own lifecycle, scaling rules, and failure isolation—so issues in one module never take down the whole system.
We build in Apache Kafka for async event flows, Resilience4j for circuit breaking and fallback strategies, and service discovery patterns using tools like Consul or Eureka—giving your system self-healing and elastic scale-out capabilities.
Example: An eCommerce platform transforms its legacy monolith by splitting catalog, cart, and payment flows into separate Spring Boot microservices. Now each team deploys independently, traffic-heavy services scale on-demand, and seasonal sales no longer cause slowdowns or outages.
We develop scalable RESTful and SOAP APIs that connect your applications with third-party services securely and efficiently. Spring Boot’s built-in JSON and XML support simplifies data exchange, ensuring fast communication between systems. OpenAPI documentation defines endpoints clearly, making API consumption easier for developers.
Rate limiting controls traffic spikes, preventing service overload, while OAuth 2.0 authentication ensures only authorized users access APIs. Redis caching reduces database queries, improving response times for high-demand APIs. We integrate APIs with payment gateways for instant transactions, CRMs for real-time customer insights, and ERPs for automated inventory updates, aligning every integration with business workflows.
For example, a travel booking platform integrates flight and hotel APIs for real-time availability. Customers see instant pricing updates, automated booking confirmations, and live itinerary changes, enhancing the user experience and reducing manual intervention.
Traditional Java apps often struggle in the cloud—overprovisioning resources, failing under load, or needing constant manual intervention. We build Java applications that are cloud-native from the start, using Spring Cloud, Docker, and Kubernetes to ensure your services auto-scale, self-heal, and stay lean under pressure.
We implement centralized config servers, container orchestration, and in-memory caching with Redis or Memcached—so your system responds fast and runs cost-efficiently, even during unpredictable spikes.
Example: A FinTech startup runs its payment engine on AWS with Kubernetes autoscaling. During IPO surges, the platform auto-scales in seconds and scales back overnight—cutting infra costs while maintaining real-time responsiveness.
Your business needs AI-driven automation, predictive insights, and real-time decision-making. We build Java-based AI and ML solutions using Deeplearning4j, Weka, and Apache Mahout to add features like recommendation engines, fraud detection, and NLP capabilities. Models train on distributed systems with GPU acceleration, ensuring fast and accurate predictions.
We customize AI models with TensorFlow’s Java bindings, use reinforcement learning for adaptive decision-making, and set up anomaly detection models to catch fraud before it happens. Our ML pipelines handle both structured and unstructured data, integrating seamlessly with your existing Java applications.
For example, a healthcare platform builds an AI-driven diagnostic system that analyzes patient records and predicts disease risks. Physicians receive automated alerts with recommended treatments, improving decision-making and patient outcomes.
Your business runs on real-time data, and you need instant processing, analytics, and decision-making. We build high-speed data pipelines using Apache Kafka, Apache Flink, and Java-based big data frameworks to handle continuous data streams. Our event-driven architecture ensures that every piece of data is ingested, transformed, and analyzed the moment it arrives.
Your system processes millions of events per second with Kafka Streams for distributed processing, Flink for complex event analytics, and Hazelcast for ultra-fast, in-memory computing. We set up custom data connectors to link with databases, IoT devices, and third-party services, keeping all your systems in sync.
For example, a stock trading platform processes real-time market data, executing trades based on AI-driven signals. Traders receive instant alerts on price fluctuations, ensuring split-second decision-making and risk management.
We automate your Java development pipeline so you can release updates faster without worrying about manual errors. Every code change goes through automated builds, testing, and security checks, making sure it’s stable before deployment. Your application scales automatically, handles traffic spikes, and stays up even during updates.
Your CI/CD process keeps everything running smoothly—new features roll out without downtime, and if something goes wrong, quick rollbacks prevent disruptions. Security checks catch vulnerabilities early, and automated infrastructure setup saves hours of manual work. Controlled releases ensure only tested updates reach users, so there’s no risk of broken features going live.
For example, a banking platform automates its deployment process, allowing frequent feature releases without downtime. Developers push updates confidently, testing is fully automated, and production rollouts happen without service disruptions.
Old Java systems—Java EE, Java 6/7, SOAP APIs—weren’t built for today’s speed or scale. We modernise these platforms by upgrading to Java 17+, modularising them into Spring Boot or Quarkus services, and rewriting slow or brittle components with scalable patterns.
We also transform legacy SOAP integrations into developer-friendly REST or GraphQL APIs, so your teams can move faster and your platform plays well with modern tools.
Example: A telecom platform migrates from Java 6 + EJBs to Spring Boot microservices. The result? Cold starts drop by 50%, integration partners onboard in days (not months), and the codebase finally supports CI/CD.
