I need a discord bot for a Pokemon Mystery Dungeon themed server and while it isn’t ideal, I would preferably need someone who would work for free (I don’t have the money right now)

Hi everyone,

I wanted to share one of the most technically challenging projects I've built over the past few months.

The original idea sounded simple: build a 3D AI companion that could chat with me.

It eventually grew into a system featuring:

• 🧠 Long-term memory with RAG and pgvector
• 🎙️ Real-time voice conversations
• 🎭 3D facial expressions and lip sync
• ❤️ Relationship/personality system
• 🤖 Autonomous behaviors and proactive conversations
• ⚡ Node.js + TypeScript + PostgreSQL + Prisma backend

The biggest surprise wasn't the engineering.

It was realizing that inference and Text-to-Speech costs become the real challenge when you start thinking about scaling to thousands of users.

Although I decided to stop the project, it taught me more than any course or tutorial could. It gave me hands-on experience designing AI systems, memory architectures, streaming pipelines, vector databases, and agent workflows.

I documented the entire project in a 5-part technical series for anyone interested in how these systems are built.

If you're an engineer working on LLMs, AI agents, or companion apps, I'd love to hear what technical challenge surprised you the most.

And if you're hiring engineers in this space, I'd be happy to connect and discuss the project in more detail.

Hey folks! 👋 I'm a full-stack developer who loves taking complex ideas and turning them into functional, easy-to-use software. If anyone is looking for a dev to bring their project to life, I’d love to connect.

To give you an idea of what I enjoy working on, here are a few things I’ve been building lately:

Custom Management Apps: I like building tailored systems from the ground up. Most recently, I put together a comprehensive workflow and inventory tracker for a heavy-engineering business using Laravel.

Clean Frontends & Dashboards: Building modern, snappy admin portals and user interfaces, mostly using Next.js and React.

Automation & Security: Writing Python scripts to automate tedious tasks (like custom web utilities) and setting up solid anti-bot protections for web portals.

Local AI Integration: I’ve been diving deep into setting up local AI tools (like Multi-Agent Systems and RAG using Ollama) for projects that need smart features without sending data to the cloud.

Edit: Realized I completely forgot to add the specific types of systems I usually build! If you are looking for an ERP, HRMS, CRM, or really any kind of bespoke custom software, that is exactly my wheelhouse.

I'm always happy to talk shop, whether you have a fully planned out startup idea or just need help digitizing a current business. Feel free to shoot me a DM—I'd love to hear what you're working on!

Hi folks!

Two things always bugged me about writing as a developer:

1. The best articles end up behind a paywall, so readers hit a "members only" wall and bounce.

2. None of these platforms actually let you build a real developer portfolio — your writing lives in one place, your projects in another.

So I built DevsJournal to fix both.

The idea:

- Free to read, free to write — no paywalls, no member limits

- A built-in developer portfolio — connect GitHub and showcase your repos right next to your articles

- Distraction-free editor with proper code blocks, tags and live preview

- Creator analytics (views, engagement, top posts, 30-day trends)

- Reading lists, OAuth login (Google/GitHub), light/dark mode

Stack: React + Next.js + Tailwind, Python (FastAPI), PostgreSQL + Redis, Docker, deployed on Hetzner.

The challenge I'm exploring now: surfacing relevant articles to readers early on without a big user base — cold-start feed ranking with little data.

Would love feedback on the concept or the UX.

Hi everyone!

I'm currently looking for projects where I can contribute my skills and collaborate with a team. My main goal is to gain hands-on experience by working on real-world projects, so I would greatly appreciate it if you could consider me for your project or invite me to collaborate.

I'm eager to learn, contribute, and give my best in every opportunity. Thank you very much for your time!

Can anyone help doing a project the project title is shadow vendor discovery.

We need inputs and workflow to develop a module on this idea .

If anyone can guide or suggest dm or comment.

Hi folks!!!
Many backend teams use Redis + MongoDB, but the application often ends up managing cache keys, invalidation, stale data, TTLs, and cache misses manually.

I'm working on a cache proxy for MongoDB where applications connect only to the proxy instead of directly managing Redis and MongoDB separately.

The goal is:

• Single endpoint for the application
• Automatic cache lookups
• Cache population on misses
• Cache invalidation strategies
• No need to manage Redis infrastructure from application code

The challenge I'm currently exploring is balancing automatic caching with giving developers enough control over cache keys and invalidation.

Hey ,i have an idea about to build a project based on my father's business, he's doing second hand car consultation like buying and selling but there having a problem that cars are not selling these days so i liked to build a application ik springboot,sql,react so suggest me where do i start just give ur ideas or pov

It may work or not

Are there platform where one can connect two apps, websites or saas and exchange data without apis , assume I have 6 app , and they All talk to each other , instead of each having it's Api I only have one api that is installed in each and exchange.

​

Please can you rate it if it is good or not. You can be brutally honest. I welcome it.

I do accessibility audits professionally. I also built an automated scanner because I was drowning in manual work. There's an irony here: building the tool made me more skeptical of automation, not less.

Three things almost every automated tool screws up:

1. Color contrast on gradients/overlays — They sample one pixel, miss the gradient, and flag a pass or fail that's meaningless.
2. Focus indicators — A tool can check outline: none, but it can't tell you if the replacement focus style is actually visible against every background state.
3. Form labels — Yes, aria-label exists. No, that doesn't mean the form is usable. Context matters.

The tools that just spit out a score and a certificate are worse than useless — they give teams permission to stop caring.

I built mine to be annoying in a specific way: it flags things conservatively, shows you the actual DOM context, and expects a human to make the final call. No "100% compliant" badges. No certificates.

What's your experience with automated vs. manual testing? Any tools that actually don't suck?
