Hey everyone! 👋 Here's a quick intro:

- Dad & husband.
- Once upon a time, I was backpacking in Asia, sleeping on beaches
- $20k grant winner for @desoprotocol 🚀
- Co-founded a top-3 Russian crypto exchange (we learned a lot in the 2018 crash – a $1M lesson!).
- Built 4 AI SaaS projects in 2023.
- Random fact: I used to be top 5 in Warcraft 3 2v2 EU. ⚔️

Let's connect!

@Samaytwt Antigravity just doesn’t work at all: it’s always down and when it’s not it’s corrupt files and trying to fix it spending all the tokens

[Vladimir Kosenko @web3brightside]

@donk8r Agree, every time I use fresh docs in the context or use usecontext7 for example I have MUCH better output. The same with “plan before code”

@heyblake Building https://t.co/1N8J7WVRKl AI agents without any dev knowledge

Hey folks!

AI agents often have a steep learning curve, right?

We’re building something to make them super easy for anyone to use, no coding needed.

We just want to validate the idea - can you check out our site? Drop “link” in the comments.

Does it feel clear and simple?

[Vladimir Kosenko @web3brightside]

Seeing AI agents literally everywhere. I’ve come out of isolation to shamelessly join the hype.

What are you guys building today?

Trading crypto?

I've been there, lost money too.

Now I'm testing my own trading algorithms.

So far, promising results. 6 trading pairs, FREE buy/sell signals.

(my account wasn't stolen btw :D)

Hey, folks!

Recently, we’ve been working extensively on an algorithm for trading in the cryptocurrency market and have achieved good results.

Test it out now and see the difference—no strings attached! 💹

Struggling with complex UI interactions in React?

State machines are your answer!

They provide a structured way to handle different states & transitions.

Check out this traffic light example using XState

Ever wondered how some JavaScript libs seem to magically modify object behavior?

It's often thanks to Proxies!

Proxies are a powerful feature in JavaScript that allows you to create a "trap" around an object, intercepting and customizing operations

In the example below, the handler object defines a set trap. Whenever a property is assigned to the person object (which is a Proxy), this trap is invoked.

We check if the property is 'age' and if the value is a number. If not, we throw an error

Want to work with array elements more efficiently? Destructuring and the rest operator can help you manipulate arrays with elegance and precision.

Destructuring isn't limited to objects. It's incredibly useful for working with arrays, especially when you need to extract specific elements or handle a variable number of items. Combine it with the rest operator for even more flexibility.

React apps scaling in the cloud?

Imagine your React app suddenly goes viral. Users flood in, and your server buckles under the load.

That's where load balancers step in.

They act as traffic controllers, distributing incoming requests across multiple server instances.

This not only prevents overload but also ensures high availability.

Here's a simplified breakdown of a common load balancing algorithm: Round Robin.

It's like a carousel, evenly distributing requests to each server in turn

Do you remember what your first salary was when you entered the IT/Tech field? What were you doing?

I remember that in school, I was asked to create a website for a photography contest.

They paid me 3 (three) dollars :D

Think you’re only paying 20% APR?

Think again. Credit card interest compounds daily, turning small debts into big ones

Let’s say you owe $2,000 with a 20% APR
Most people assume they'll pay $400/year in interest (20% of $2,000)

Wrong

Since interest is calculated daily, it compounds like this:

By the end of the year, you’ll owe closer to $442 in interest, not $400

That’s an extra 10%+ just from compounding

- Pay off your balance before interest kicks in
- Make extra payments
