Behind the scenes, we’re running webhooks, Celery, and other background processes to ensure a smooth and reliable payment flow. As you can see in my setup image, though it's more complex than what the graphical illustration portrays. #payments #engineering #product

Hi community, I’m Tolulade, a software data engineer. Three years ago, a close associate of mine joined a major fintech as a junior engineer, eager to grow her career. Due to poor mentoring and unclear delegation, she eventually pivoted to product management, and later resigned. Stories like hers aren’t rare. Businesses lose millions every year to employee attrition driven by low engagement and lack of development. We built a platform that helps companies reduce attrition risk by 20–30%, and boost employee satisfaction. By correlating learning activity with retention, we’ve found that low learning rates double churn risk, while healthy engagement can increase profitability by up to 25%. https://semis.reispar.com Warm regards,

I'm running some analytics tests on a staging environment with @posthog (https://x.com/posthog) before we launch into prod. I successfully integrated Posthog into our NextJS app using their documentation. I love Posthog. Their UI and features are so sleek, maybe because I'm an analytics guy! #analytics

Cover image for Sendy Email Infrastructure Deployment A manufacturing
Sendy Email Infrastructure Deployment A manufacturing business needed a reliable, self-hosted email marketing platform to manage its growing contact database and send newsletters at scale. They wanted full control over their email operations while maintaining strong inbox placement. The project involved deploying Sendy on an Ubuntu VPS, integrating Amazon SES and Postmark, configuring Apache, PHP-FPM, MariaDB, SSL, and DNS authentication (SPF, DKIM, and DMARC), resolving installation and server configuration issues, verifying the mailing list, warming up the sending reputation, and optimizing deliverability before launching campaigns. Through this project, I strengthened my expertise in Linux server administration, email authentication, SMTP integrations, deliverability optimization, and large-scale email deployment. The outcome was a stable, secure, and scalable email marketing system that gave the client greater control over email campaigns, improved deliverability, and reduced long-term sending costs.

Cover image for Building a Self-Hosted Email Marketing
Building a Self-Hosted Email Marketing Infrastructure with MailWizz & Postal Overview Quad Nathan needed a reliable, self-hosted email marketing system that would give them full control over their email campaigns, mailing lists, and sending infrastructure while reducing dependence on third-party email platforms. About the Client Quad Nathan is a business seeking a scalable and cost-effective email marketing solution capable of managing campaigns, subscriber lists, and high-volume email delivery through its own infrastructure. Goal The objective was to deploy a secure and fully functional email marketing ecosystem using MailWizz and Postal, ensuring the platform was properly configured for campaign management, email authentication, and dependable email delivery. Challenges The project involved configuring multiple server components, integrating MailWizz with Postal, securing the server with SSL, and implementing proper DNS authentication (SPF, DKIM, and DMARC). Careful tuning was also required to ensure stability, performance, and reliable email delivery. Solution & Outcome A complete email infrastructure was successfully deployed on a Linux VPS. Postal was configured as the SMTP server, while MailWizz was installed and connected for campaign management. SSL certificates were implemented to secure the platform, DNS authentication records were configured, and the entire environment was tested to confirm successful email transmission. The client received a production-ready system capable of managing email campaigns independently. Knowledge Gained This project strengthened my expertise in Linux server administration, MailWizz deployment, Postal configuration, Docker-based services, DNS management, email authentication protocols, and end-to-end email infrastructure deployment. Business Impact With a self-hosted email marketing platform, Quad Nathan gained greater control over email operations, reduced recurring software costs, improved scalability, and established a foundation for reliable and secure email marketing as the business grows.

Most people pay for a VPN. I decided to build mine from scratch instead on my own server, with zero tracking and full control. I just turned the whole process into a simple guide so anyone can do it too. 🔗https://michaeltech.xyz/2025/10/13/how-i-set-up-my-own-private-vpn-and-how-you-can-too/ Would you rather own your VPN or rent one forever?

Cover image for I'm putting DoNotify (Voice Call
I'm putting DoNotify (Voice Call Reminders) up on Product Hunt today. A few months back I missed a time-sensitive WooCommerce order because it landed in an inbox already buried under 200 unread emails. Email and SMS are easy to snooze. A phone ringing isn't. So I built a small WordPress plugin that does one thing: it calls you, the site owner, when something needs your attention. A new order, a completed order, a failed payment, a new booking through WooCommerce Bookings or Amelia. Developers can wire up their own triggers too, with a single hook: do_action('donotify_call', 'New VIP lead'). The plugin itself is free on WordPress. org. Placing the actual calls needs a DoNotify account with an active subscription. Right now it calls the store owner. Calling customers directly, for appointment reminders or delivery updates, is next on the list. If you run WooCommerce or take bookings through WordPress and want to know the second something happens, I'd like you to try it and tell me what's missing. Link in the comments. An upvote helps more than you'd think, and I'm reading every comment today.
