Decided not to continuously copy/pasting the same message over and over again and decide to be genuine again.

With that said, Welcome everyone! What brings you here?

Manal • Sep 27

Hi Francis , Just found my way here and figured I’d join the community. Hoping to learn a lot and maybe make some cool stuff along the way 😎😌 and I’ve been learning and building on my own, and thought it’d be nice to actually connect with other developers doing the same.

The Working Nemo • Sep 28

That's cool - You will be always having the latest updates too.

Manal • Sep 29

❤️

Priya Santos • Sep 29

Welcome, Manal! Python is a great first language, and it's also really useful for automating everyday admin tasks. Enjoy the experimenting phase; that is where most of the learning happens.

Manal • Sep 29

Thank you Priya 💖🌸

FrancisTRᴅᴇᴠ • Sep 28

Same here! Hope you will find your place here on DEV! What things have you built so far that your proud of?

Manal • Sep 28

Well I’m pretty new to coding actually , I’ve just started learning Python. So far I’m focusing on the basics and experimenting with small things. Excited to see where it takes me 😊💖

Welcome! 👋

Pavel Kazantsev • Sep 24

Hey Francis! Brought here by a failed backtest, honestly. I've been running quant experiments on crypto and prediction markets, and realized the only way to make it useful is to write it up publicly. Just posted my first article — Sharpe 13.4 before trading costs, -40.1 after. Clean failure, but worth documenting.

Arhan Canli • Sep 28

Welcome, Pavel! Writing up the failure is the right call; far more people learn from those than from the wins. A Sharpe of 13.4 before costs is a useful flag in itself: numbers that high usually mean the strategy trades so often that costs are most of the story, or something in the data is too good to be true. How many trades a day was it making? I'd love to read the write-up.

Pavel Kazantsev • Sep 28

Thanks! Yeah, 15-minute rebalancing across ~20 coins — easily 200-300 position changes per day. Turnover killed it before anything else got a chance.
Already moved on to other hypotheses, like funding carry, momentum, and a football prediction model. All failed for completely different reasons. Writing them up as I go.

Arhan Canli • Sep 28

200 to 300 changes a day explains it: even a few basis points per change adds up to more than most signals can earn. Writing each failure up also sets you up for the part people usually skip, which is that every hypothesis you try adds to the count. If funding carry or momentum eventually passes, the fair bar for it is set by all the ideas you tried before it, not just its own backtest. Your football audit post is next on my reading list; five checks is more than most people ever run.

Pavel Kazantsev • Sep 28

That multiple testing point is real and I don't have a clean answer for it yet. Pre-registering helped on the football one but across ten experiments it adds up.

And yeah, if you ever have ideas you want stress-tested - throw them my way, I'll run them through and post the results whatever they are.

Omaima Ameen • Sep 25

Heyyy!! this sounds super interesting, would love to connect with you and learn more about your experiments!

I am an ai/ml and gen ai enthusiast...currently aiming to ace challenges on this platform

Priya Santos • Sep 29

Mostly to share what I learn from working with small teams on Microsoft 365 and Azure, and to pick up ideas from people building in areas I know less about. Nice approach on skipping the copy-paste, welcome, by the way.

Bright Jasper • Sep 26

Hello Francis
Thank you!

I've seen alot of great posts and i'm glad to feel at home!

Bryant Hood • Sep 29

Hi! Glad to be hear to learn more about AI/Software architecture, best practices, and cutting edge thought models. Look forward to learning from all of you!

Hii :D

Naveen Alavilli • Sep 23 • Edited

Hello from Houston. 👋

Naveen. Software architect, about seventeen years in, most of it building .NET and Python systems for government agencies. That work means a lot of forms, workflows and business rules that arrive from statute rather than from anyone's product roadmap, which has shaped how I think about software more than I expected it to.

Lately it has been Azure, RAG and ML.NET. The recurring lesson is that the model is never the hard part. Deciding what the system should refuse to do is the hard part.

Read here for a long time, finally made an account. Working on a first post about form builders and validation rules that are themselves invalid, which turns out to be more interesting than it sounds.

@io64bit opening the thread with a hello world is a choice, and I respect it.

Veil In Sec • Sep 25

Hello Naveen,

I am new here; let's build a good trust.

Naveen Alavilli • Sep 27

Welcome to the community! Looking forward to seeing what you post.

Anna Villarreal • Sep 24

Welcome to the party @naveen_alavilli !

Omaima Ameen • Sep 25

heyyy Naveen , 17 years in software is WILDDD!!

i'm a self-taught dev, mostly into react/rext.js, node.js bug fixing, and I LOVE hearing how experienced engineers think about software beyond just making things work.

definitely looking forward to reading your post.
Welcome to the community!!

Naveen Alavilli • Sep 27

Thanks, Omaima! Self-taught and already fixing Node bugs in production is its own hard-won experience — the "beyond just making things work" part comes from getting burned a few times either way. Welcome, and hope the post's useful.

Roy Moris Tolosa • Sep 29

Hey Naveen! 17 years in software is impressive. 😄 The part about deciding what a system should refuse to do being harder than the model itself really caught my attention. Looking forward to reading your post about form builders and validation rules!

Naveen Alavilli • Sep 30

Thanks Roy! Yeah, deciding what a system should flatly refuse to do usually ends up being the harder design problem than the model logic itself. Appreciate you following along.

Hello and Welcome!

daniel • Sep 28

Welcome! 👋 Loved reading your intro. I’m curious — what’s one AI tool that’s actually made it into your daily routine? I’m always looking for real-world use cases, not just hype.

Dylan Scott Mickelson • Sep 28

Thanks for your reply! That's a really good question. I mainly like to think of AI as a tool instead of a know-all. I only use AI for automations, workflows, and loops using N8N. It's a pretty cool tool since it allows you to connect to many different API's and services. It is also easy/free to download and use with Docker Desktop. Check out how to install and use it here: N8N Docker Install
