10 users broke my app. But I'm not giving up.Yesterday was exhilarating and humbling. WhatsFlow launched, and we got our first 10 users!Then our 1GB RAM machine crashed. Classic, right?Here's the thing: In 2016, I coded on a second-hand Dell with 512MB RAM. Today, I'm wrestling with memory leaks in the cloud. The irony isn't lost on me.But this isn't a setback. It's a setup for a comeback. Here's how I'm fixing it:1. Implementing session timeouts2. Cleaning up inactive WhatsApp clients3. Optimizing logging4. Writing end-to-end tests5. Monitoring for memory leaks6. Upgrading our infrastructureI'm building in public because I believe in transparency. This journey isn't just about code—it's about resilience.If you've ever faced a technical challenge that felt insurmountable, I'd love to hear your story. And if you're feeling generous, you can fuel my late-night debugging sessions with a virtual coffee: https://lnkd.in/dsp_BKPmRemember: It's not about the RAM you have, but how you use it. 💻💪#buildinpublic #techentrepreneur #startupjourney

Hey Linkedin fam,🚀 Big Update: WhatsApp Scheduler Bot Now Has a UI!Remember that WhatsApp scheduler bot I mentioned a few weeks ago? Well, it's evolved into a full-fledged web app! 🎉Why build this? Simple: I needed it. As a developer, I often find myself wanting to send messages at specific times - reminders, birthday wishes, or just checking in on friends. But manually sending these? Ain't nobody got time for that.So, what's new?👉 Sleek UI: No more command line. Schedule messages with a few clicks.👉 Google Sign-In: Easy, secure authentication.👉 Supabase Integration: For robust user management and job storage.👉 Multiple Recipients: Send to up to 3 people or groups at once.What I've learned:- Supabase is a game-changer for quick backend setups.- Handling scheduled jobs across server restarts is crucial (and not straightforward).Check out this quick demo belowWhat's next? - I'm currently, restructuring the repo and deploying. You'll get a live link to play with this week.- While the core functionality is open-source, I'm also working on some exciting premium features. If you're interested in a more robust, business-oriented solution, let's connect!Shoutout to the open-source community and especially the whatsapp-web.js library. This project wouldn't be possible without you.Want to try it out or contribute? Here's the GitHub repo: https://lnkd.in/dEqxy72ALet me know what you think! Always open to feedback and collaboration.#buildinpublic #whatsapp

Hey, Linkedin fam!Over the weekend, I thought about how WhatsApp doesn't have a scheduler bot for messaging. So I created a WhatsApp bot that can automatically send scheduled messages.Perfect for:✅ Regular check-ins with loved ones✅ Sending daily motivation to a friend✅ Reminding yourself to take breaks or meditate It's customizable, easy to set up, and can send to individuals or groups. Plus, you can include images! I used the whatsapp-webjs client library as it's free and in my use case a better option than the Cloud API(https://lnkd.in/dJEX7XGE).Check out this GitHub Gist here: https://lnkd.in/d_P-kZ_cI'm still working on the technical documentation for https://metaeenfo.live. An idea for later would be building a UI for this so that non-developers can use it.#javascript #automation
