Backend engineer needed for mail server project.

@rahuliitm69

Hello there, I specialize in Node.js, TypeScript, and Linux mail server architecture (Postfix, Dovecot), and I can take your existing system from “vibe-coded” to production-grade. I'll refactor and harden the current logic, implement robust API endpoints, add reliable error handling, and ensure clean, stable deployment across edge cases. I have experience automating VPS mail stack setups, working with Cloudflare APIs, and optimizing SMTP routing for deliverability. I’ll deliver a thoroughly tested microservice that’s stable, extensible, and fully ready to plug into your SaaS infrastructure with confidence. Thanks Rahul B.

OVER 10 YEARS OF EXPERIENCE IN NODE.JS & MAIL SERVER AUTOMATION – PRODUCTION-GRADE DELIVERY Hey there! The biggest risk with projects like this is leaving “vibe-coded” logic unpolished—things may work 80% of the time, but when you scale or face real-world edge cases, you start running into downtime, broken configs, or blacklisted IPs. That’s exactly where I come in: I’ll refactor and harden the entire flow so your mail server automation is not just functional, but truly production-ready. I’ve worked on SaaS microservices and mail stack automation before (Postfix/Dovecot on Ubuntu, Cloudflare DNS, DKIM/SPF/DMARC), so I know how to build something stable that survives stress tests and can handle retries, errors, and edge cases without breaking. My plan would be to carefully audit your current codebase, clean up the logic, add strong API endpoints, and ensure it integrates seamlessly into your SaaS as a plug-and-play microservice. On top of that, I’ll implement structured logging, retries, and monitoring so you don’t have to manually track down issues later. By the time I’m done, you’ll have a stable, tested, and secure system that just works when you plug it into your product—no hidden fires waiting to pop up later.

Hi, We understand your requirement for a seasoned developer with a strong background in Node.js, TypeScript, and Linux mail servers, to fine-tune and productionize your existing SaaS project. This entails making it production-ready, adding API endpoints, extensive testing, and improving the current code. Having worked on similar projects, we're curious to know more about the current state of the codebase. Are there specific areas that you think need more attention than others? Have you identified any potential areas of improvement or issues that need to be addressed in the current codebase? As requested, we will not include any URLs here. However, we have extensive experience in automating mail server operations and developing Node/TypeScript SaaS microservices, and we'd be happy to share relevant examples in a private chat once we connect. We would love to connect via message or a call to discuss your project in detail and understand your needs better. Depending on the scope of work and the current state of the project, we can provide an accurate timeline and quote. We look forward to the possibility of working together, not just on this project but potentially on a long-term basis. Best Regards, Rohit

Hi there! Sounds like what you have now is a working prototype that needs a proper production-grade refactor—strong error handling, API endpoints, and rock-solid stability for mail automation at scale. I’ve been building Node.js + TypeScript solutions for 8 years, including microservices with advanced API architecture and automation scripts on Linux. I’ve also handled mail stack setups with Postfix/Dovecot on Ubuntu and hardened them for security and performance. Recently, I worked on a SaaS email infrastructure for a marketing platform. I refactored the existing “MVP” code, implemented robust logging and retry logic, added health checks, and stress-tested it using k6 and custom scripts to ensure zero downtime. Here are some solutions to complete the project: 1. Refactor and modularize the Node.js/TS codebase for maintainability and speed, reducing future bugs. 2. Implement full error handling, logging, and retry logic so the system is stable under stress. 3. Add REST API endpoints and automated tests to make integration seamless and reduce QA overhead. I can prepare a quick architecture outline and sample API endpoint within 3 days to show how I’d make it SaaS-ready. If we move forward, I’ll make sure this becomes the production-grade solution you need—but even if not, I hope you find the right fit for this critical piece. Would you like me to share the initial API structure proposal this week?

As an experienced full-stack developer with a deep understanding of Node.js, I believe I'm the ideal candidate to complete the final 20% of your mail server project. I've worked on numerous projects involving Linux mail servers, including Postfix and Dovecot, and my knowledge and expertise will be invaluable in making your SaaS robust, stable, and production-ready. In addition to haunting and polishing code, I understand how essential it is for a microservice to have well-defined API endpoints that seamlessly integrate into existing systems. My proficiency in TypeScript will ensure that your backend aligns perfectly with your SaaS's requirements. Moreover, I bring extensive experience in handling error-prone scenarios, testing applications thoroughly to ensure their reliability, and employing proper logging for effective debugging. A key strength of mine lies in being able to detect underlying issues early on and then refactoring the code accordingly. Once these are identified, I implement necessary steps (like error handling improvements, retries etc.) to strengthen the setup even further. My goal is not just to complete a job but to deliver a long-lasting masterpiece, built on solid fundamentals that can be relied upon unquestionably. So let’s work on this together!

@diektech

Hi, this is Elias from Miami. I’ve gone through your project, and from what I understand, the goal is to take your current ~80% working mail server automation app and make it production-ready: clean code, hardened logic, proper API endpoints, error handling, and full testing so it can run as a reliable microservice within your SaaS. With over 10 years of experience in Node.js and TypeScript, plus hands-on work deploying and managing Postfix/Dovecot on Linux, I’ve built systems where custom provisioning tools (SSH-based setup, DNS automation, SPF/DKIM/DMARC integration) had to be bulletproof before going live. I’d love the opportunity to work with you on this final stretch — not just patching, but restructuring where needed so the foundation is solid. A few focused questions: Q1: For the health/blacklist checks, do you want alerts sent directly to admins (for example via email or Slack), or just stored/logged in the dashboard? Q2: Are you envisioning these API endpoints to be REST-only, or do you want GraphQL/webhook events for easier integration into your SaaS? Q3: When scaling to multiple VPS setups, should the system orchestrate and monitor them all centrally, or is this microservice focused only on single-server provisioning per request? Looking forward to hearing more about how you’d like this polished. Regards, Elias
