Hi, buddy, I see you need a skilled J2EE and Node.js developer to migrate your web application while keeping all features intact. I have hands-on experience migrating J2EE apps to Node.js, integrating APIs, managing MariaDB/PostgreSQL databases, and implementing reliable scheduling systems. I can ensure a smooth migration with all functionality preserved and optimized for performance. Best regard. Denis.

@kamran2012

Hello, I can help migrate your J2EE web application to Node.js while retaining all existing features, including scheduling, external service APIs, and database updates across MariaDB and Supabase PostgreSQL. My approach will be to analyze the current J2EE modules, map their logic into a modular Node.js architecture (Express/NestJS), and implement scheduling with reliable libraries (e.g., node-cron or Bull queues). I’ll ensure APIs are migrated cleanly, database migrations are stable, and the new system is fully documented for future maintainability. Questions: – Should the scheduling system be a like-for-like replacement of the J2EE tasks, or would you like it modernized (e.g., distributed queues, better retry logic)? – Do you want both MariaDB and Supabase supported long-term, or should the migration consolidate everything into PostgreSQL? – Which parts of the J2EE app are most critical to keep unchanged (business rules, API endpoints, workflows)? I am a TOP Rated Freelancer, and you can check my reviews here as well: https://www.freelancer.com/u/kamran2012 Looking forward to potentially working together on this project. Thanks and Best regards, Kamran.

Nick, for the J2EE to Node.js migration project, would it be fine if I first analyze the existing J2EE web application and then propose a clear strategy for the migration process? So I believe a successful migration to Node.js will enhance the web application's performance and scalability, ensuring seamless functionality for scheduling, API integrations, and database updates. By the way, could you share more details about the existing tools used for scheduling and API integrations to better plan the migration process efficiently?

@Feriver

Hello, I understand you’re looking for an experienced developer to migrate your J2EE web application to Node.js while retaining all core features such as scheduling, external API integrations, and database updates with MariaDB and Supabase PostgreSQL. I bring over a decade of hands-on expertise in Java/J2EE enterprise applications and modern Node.js frameworks, enabling me to handle both the legacy system and the transition with precision. My approach will involve a structured migration process: auditing existing J2EE components, mapping services to Node.js modules, and ensuring feature parity with no downtime. Scheduling tasks can be rebuilt using Node-based tools like node-cron or BullMQ, while APIs and database connections will be modernized for scalability. I prioritize clean, maintainable code with automated testing to validate each stage of migration, ensuring a smooth rollout. I have successfully led enterprise projects involving full-stack migrations, where complex backend logic, API workflows, and database layers were seamlessly rebuilt in Node.js. By combining scalable architecture, robust testing, and modern DevOps pipelines, I will deliver a secure, efficient solution optimized for long-term performance and easy maintenance. My goal is to ensure your application evolves into a future-ready Node.js platform without compromising existing functionality. Thanks, Asif

@Herculesz

Hi, I have hands-on experience migrating enterprise J2EE applications to Node.js, ensuring all business logic, schedulers, and API integrations are preserved and optimized. A key challenge in such migrations is decoupling Java-based schedulers and servlet logic — I handle this by translating them into Node.js-based job schedulers (like node-cron or Agenda) while maintaining database consistency across MariaDB and Supabase PostgreSQL. I also work with tools like Cursor and Claude AI Dev Tools to assist and accelerate code transformation. I’ve led successful migrations without feature regression and can deliver a clean, modular Node.js architecture ready for production. Thanks, Hercules

As a developer who has not only been exposed to J2EE and Node.js but has actually worked in-depth with both languages, I believe I can bring a unique perspective to your migration project. My experience at Queue Solutions was predominantly focused on web development with React and Node JS; however, my competence with languages like Java and JavaScript, which lie at the core of J2EE and Node.js, will definitely come in handy for the successful completion of this task. Another crucial dimension of your project is the requirement to retain existing features - scheduling, APIs to external services, updating databases. I have a strong understanding of these functionalities and have implemented them effectively in previous projects. Moreover, my knowledge of MariaDB and PostgreSQL will ensure seamless integration with these databases. Lastly, I understand that this migration should not only retain the previous application's functionality but also enhance it further. Having worked on several similar migrations, I am well-versed in anticipating potential challenges and targeting appropriate solutions. All these make me confident in my ability to handle your project effectively and resolutely. Let's work together to bring a new impetus to your web application!
