I'm not technical. Can I work with iDev?

Absolutely. Most of our clients are non-technical. Just tell us what you want the end result to look like — we handle all the technical details.

How much does it cost to hire iDev?

We quote individually based on project scope and complexity. Initial consultation is completely free — we give you a clear quote after understanding your needs. No fit, no charge.

How big is the iDev team?

A few core members, each capable of delivering full-stack independently. We flexibly assign people based on project scale and can run multiple projects simultaneously.

What happens after project delivery?

We provide complete code and documentation at handover. For ongoing feature development or maintenance, we offer monthly or per-project arrangements. Most clients choose long-term collaboration.

What if I'm not satisfied with the project midway?

We confirm with you at every stage before moving forward. If the direction is off, we adjust immediately. If it truly can't continue, completed work is settled normally and all code is yours.

我完全不懂技术，能合作吗？

当然可以。我们的大部分客户都不是技术背景。你只需要告诉我们你想要什么效果，技术实现的事情完全由我们来处理。

费用大概是多少？

根据项目复杂度和功能范围单独报价。初次沟通完全免费，我们会在了解需求后给出明确报价，合适再开始，不合适不收费。

团队有几个人？

核心团队几个人，都是能独立交付的全栈开发者。根据项目规模灵活安排人手，可以同时推进多个项目，不用等排期。

项目做完以后怎么维护？

交付时会提供完整的代码和文档。后续如果需要功能迭代或维护，可以按月或按次合作。大部分客户选择了长期合作。

做到一半不满意怎么办？

每个阶段交付前都会和你确认。如果方向不对，我们及时调整。如果实在无法继续，已完成的部分正常结算，代码归你。

Java Loom 结构化并发实战：告别回调地狱的新范式

Java Loom Structured Concurrency in Practice: A New Paradigm Beyond Callback Hell

深入探讨 Java 21+ 中结构化并发（Structured Concurrency）的核心概念与实战应用，通过真实案例展示如何利用 StructuredTaskScope 简化并行任务编排。

An in-depth exploration of structured concurrency concepts and practical applications in Java 21+, demonstrating how StructuredTaskScope simplifies parallel task orchestration through real-world examples.

结构化并发：Project Loom 的下一个里程碑继虚拟线程（Virtual Threads）之后，Java 的 Project Loom 项目带来了另一个革命性特性——结构化并发（Structured Concurrency）。JEP 480 在 Java 23 中正式成为稳定特性，为 Java 开发者提供了一种全新的并发编程范式。什么是结构化并发结构化并发的核心思想是：并发任务的生命周期应该与代码的结构化块保持一致。就像结构化编程消灭了 goto 语句一样，结构化并发消灭了无序的线程创建和管理。任务的启动和完成都在同一个作用域内父任务会等待所有子任务完成后再退出子任务的异常会自动传播到父任务取消操作会自动级联到所有子任务StructuredTaskScope 实战StructuredTaskScope 是结构化并发的核心 API。它提供了两种常用策略：ShutdownOnFailure（任一失败则全部取消）和 ShutdownOnSuccess（任一成功则全部取消）。在微服务场景中，这些策略可以优雅地处理并行 API 调用、超时控制和错误传播。与虚拟线程的协同结构化并发与虚拟线程是天然搭档。虚拟线程提供了轻量级的执行单元，而结构化并发提供了管理这些执行单元的框架。两者结合，使 Java 在高并发场景下的开发体验达到了前所未有的水平。对于正在使用 Spring Boot 的团队，建议从 IO 密集型的服务调用开始尝试，逐步将现有的 CompletableFuture 代码迁移到结构化并发。

Structured Concurrency: The Next Milestone of Project LoomFollowing Virtual Threads, Java's Project Loom brings another revolutionary feature -- Structured Concurrency. JEP 480 became a stable feature in Java 23, providing Java developers with an entirely new concurrent programming paradigm.What Is Structured ConcurrencyThe core idea of structured concurrency is that the lifecycle of concurrent tasks should align with structured code blocks. Just as structured programming eliminated goto statements, structured concurrency eliminates unordered thread creation and management.Task launching and completion occur within the same scopeParent tasks wait for all child tasks to complete before exitingChild task exceptions automatically propagate to parent tasksCancellation operations automatically cascade to all child tasksStructuredTaskScope in PracticeStructuredTaskScope is the core API for structured concurrency. It provides two common strategies: ShutdownOnFailure (cancel all if any fails) and ShutdownOnSuccess (cancel all if any succeeds). In microservice scenarios, these strategies elegantly handle parallel API calls, timeout control, and error propagation.Synergy with Virtual ThreadsStructured concurrency and virtual threads are natural partners. Virtual threads provide lightweight execution units, while structured concurrency provides the framework for managing them. Together, they bring Java's development experience in high-concurrency scenarios to unprecedented levels.For teams using Spring Boot, we recommend starting with IO-intensive service calls and gradually migrating existing CompletableFuture code to structured concurrency.
