DAY 4/90 of AI Engineering Internship

Today was all about CS50’s Introduction to Programming with Python — Week 0.

I went through the course materials and lecture notes, then redid the assessment to test how much I had actually retained.

Day 4 done. On to Day 5.

Day 3/90 of my AI Engineering Internship!
I completed ALL the problem sets for Weeks 0–3 of Harvard's CS50 Python course.

Here's a study hack I've used since my university days:

Attempt the assessments BEFORE taking the course.

Lagos Life launched on October 1st. Just 9 days later, over 4.7 million people have played the game.

Today, I’m excited to announce that Vatar, the parent company behind Lagos Life, has closed a $500K angel round led by AB Hassan (@ijbguy), Nathan Nwachuku (@_KingNath), and GB Agboola (@TechProd_Arch).

Lagos is just the beginning. We’re building entire worlds, and there’s so much more to come. 🌍

Built a game in less than 24 hours
Now having over 10 million people in a week 😳😳😳

@Shalom_HeyEliy has shown me that nothing is impossible with the right product

PS: A fun mental exercise for those learning a second language
Mentally check and compare how different both languages are in the same elements.

[Winifred John @WinifredJohnn]

Day 2/90 of AI Engineering Internship

"Learning a programming language is like learning a new language"

Like every language, programming languages have 2 things:

1. Syntax: How you say/write it
2. Semantics: What it means

https://t.co/f0pqaCoLW2

[Winifred John @WinifredJohnn]

Every programming language has the same basic elements
1. Variables: what store values
2. Functions: reusable blocks of logic
3. Conditionals: if this, then that
4. Loops: recurring events
5. Operators and Operands: how to manipulate data

Use this first-principles understanding

DAY 1/90 of AI Engineering Internship

"AI Engineering is a subset of Software Engineering"

Following the AI Engineering roadmap released by Andrew Nguyen, I am focusing on building strong SWE fundamentals to build better AI applications.

Build Logs - POST 1

I want to build a fully AI-powered application by the next 90 Days.

The whole idea is to build on my existing knowledge and learn the rest along the way.

Here's the simple roadmap

[Winifred John @WinifredJohnn]

1. Learn the core programming language - Python

2. Software Engineering Fundamentals

3. LLM Fundamentals

4. AI agents:

CAPSTONE: I will be building a fully AI-powered E-commerce application for my Mom's fabric business.

A big thank you to @KovoLabsHQ for making my work easier

From event planning to execution they did an excellent job❤️

@CyberKet_247 @STEALFxyz You don’t unlink per say
Both are fully private on chain

But the spending account is like a daily facing account where you carry out outward transactions

Your keys and transactions are kept in the shielded wallet

[Winifred John @WinifredJohnn]

You may not know, but your Solana wallet is basically a public financial identity.

That's one reason I started looking into @STEALFxyz.

Stealf is building a privacy layer for everyday finance on Solana, solving a major problem with public blockchains: your financial activity is exposed by default.

🤧Disclaimer:

Once someone knows your wallet address, they can see your balance, transaction history, tokens you hold and the wallets you've interacted with.

So a simple wallet address can reveal a lot about your financial life

I hated that idea and am not the only person
😒

I recently came across a Reddit post asking:

“How can I send SOL from one wallet to another without showing that these two wallets interacted?”

That question made me realize people actually want to use crypto without making their entire financial history public.

This is where @STEALFxyz. comes in

💠It gives you two wallets inside one app:

🔒 A shielded wallet for your assets

💳 A spending account for everyday life

The two are not linked onchain, so your spending activity doesn't have to expose your private assets.

This is because Stealf is powered by @Arcium for encrypted computation

If you're curious, check out https://t.co/j6gxUztJHc and see what they're building.

Over 700 Beta testers have joined Stealf.

You can get it on IOS: https://t.co/0TxO4z595Q
