Team Size and Composition
A senior architect costs more per hour than a mid-level developer. Complex projects typically need both.
Project Duration
Longer engagements (6+ months) usually come with lower monthly rates than short-term projects.
Technical Complexity
Building a CRUD app is different from building a distributed, event-driven system. Architecture complexity directly affects estimates.
Compliance Requirements
Timeline Pressure
Accelerated timelines require larger teams, which increases coordination overhead. Our rates are competitive with Vietnam-based providers and typically 40% to 60% lower than equivalent US or EU-based teams, without compromising on engineering standards.

These services focus on creating custom applications, enterprise systems, APIs, modernizing legacy software, and building microservices. Companies often outsource to access skilled Java developers, DevOps engineers, and QA specialists without the cost of hiring an in-house team.
The cost of Java development depends on several factors:
As a reference, a Vietnam-based Java team typically costs 40–60% less than teams in the US or Western Europe.
For an accurate estimate, it’s best to discuss your requirements in a consultation.
Java is a strong choice for enterprise development because it is stable, scalable, and platform-independent. It offers a large ecosystem, automatic memory management through the JVM, and long-term support. Trusted by companies like Netflix and Amazon, Java is ideal for building secure, reliable systems that can run for many years.
We follow a structured approach to modernize legacy systems while minimizing risk and downtime:
They include custom application development, API integration, legacy system modernization, and microservices. Companies outsource these services to quickly access experienced developers without hiring in-house.
Project timelines vary depending on scope:
Timeline depends heavily on how clearly requirements are defined and how quickly feedback is provided during development.
Java and JavaScript are different programming languages with different purposes.
Java is a compiled, statically typed language mainly used for backend systems, enterprise applications, and Android development.
JavaScript is an interpreted, dynamically typed language mostly used for frontend web development, but it can also run on the backend with Node.js.
In many modern applications, Java handles the server side, while JavaScript (with frameworks like React or Angular) is used on the client side.
Yes. We provide SLA-based support after launch, including bug fixes, performance optimization, security updates, and ongoing improvements to keep your system stable and reliable. Security is critical. While AI can help generate code, it cannot ensure secure architecture or production readiness. Our experienced engineers review and validate every release to make sure your system is safe, stable, and ready to scale.
Yes. We offer staff augmentation, where Java developers or specialists join your existing team. You can also choose a dedicated team or a fixed-price engagement based on your project needs. Most augmentation engagements can ramp up within 1–2 weeks.
