๐ Day 17 of #100DaysOfLearning
Today, I explored the fundamentals of LLMs!
What I learned:
โข Tokens & Tokenization
โข Embeddings
โข Neural Networks
โข Weights & Parameters
โข Context Windows
โข Maximum Output Tokens
โข How LLMs understand context and generate responses.

I used to focus on features working. Now, while building MMS, I ask: โWhat could go wrong?โ
Client input, plain-text passwords, missing authorization, weak validation, exposed data and tokens that never expire are risks worth checking.

No code, just a mental health reset.
Learning that consistency isn't about coding every day. It's about building a sustainable life alongside your goals.
Fellow devs, how do you reset when life gets overwhelming? โจ

Caught up on sleep, tackled household chores & spent some much-needed quality time with my husband. ๐กโจ
A reminder that building a life you love matters just as much as building software.
How do you spend your no-code days? ๐

Imagine a customer changing product prices or staff deleting admin records. Thatโs what happens when everyone has the same access.
RBAC separates permissions by role: user, staff, and admin. The backend must enforce them.

No coding, just recharging!
A day of reading for fun, resting & spending quality time with friends. โจ
Building in public also means embracing the days spent simply living.
What's your favourite way to unplug from tech? ๐ท

While studying my backend, I also started building the frontend.
We moved from an admin dashboard to a login page, then planned a separate public product page where visitors can browse without logging in.
It's still a work in progress

Why should tokens expire?
If a token is stolen, an expiry time helps limit how long it can be used.
In my MMS backend:
Access token: 1 hour
Refresh token: 7 days
it is not just granting access, also control how long that access lasts.

....IDOR, authentication, XSS, SQL injection, business logic flaws, API security, and other common vulnerabilities.
The mission is clear: submit my first valid bug bounty report before the end of December. ๐ฏ
One step at a time. Consistency over perfection.

35 days of learning, building, debugging, and growing.
Today is for resting, reflecting, and recharging.
Consistency isn't about never resting. It's about showing up again.

What happens when you click "Forgot Passwordโ?
Generate a secure token โ Hash it โ Store the hash โ Send the reset link โ Verify the token โ Change the password.
#100DaysOfLearning #Security #PasswordHash
๐๐ฎ๐ ๐ฏ๐ฏ/๐ญ๐ฌ๐ฌ
Hashing โ Encryption.
Encryption lets you recover the original data with the right key. Hashing is designed to be one-way.
Thatโs why my MMS uses bcrypt to hash passwords instead of storing them in plain text.
#100DaysOfLearning #BackendDevelopment
๐๐ฎ๐ ๐ฏ๐ฎ/๐ญ๐ฌ๐ฌ
What if my MMS database were exposed and every password was stored in plain text?
That's why I use bcrypt. it hashes passwords and makes guessing them more expensive. My current setup uses a cost factor of 12.
#100DaysOfLearning #CyberSecurity #CRUD
๐๐ฎ๐ ๐ฏ๐ญ/๐ญ๐ฌ๐ฌ
I moved toward a minimal JWT payload: { id, iat, exp }.
Why? User roles and details changes. Fetching the current user from the database helps my backend use up-to-date information instead of relying on stale token data

An admin, staff member, and user can all log in successfully. But should they have the same permissions?
Authentication identifies the user. Authorization decides what they can do.

context using a quotation mark and inject malicious JavaScript.
Iโm learning to look beyond the obvious and understand how context affects XSS vulnerabilities. ๐

Been MIA from my #100DaysOfLearning journey for 12 days, thanks to my research paper.
Finally done! Will share updates soon.
Tomorrow, back to coding and my Tech journey.

A rest day after a week of exploring PostgreSQL, database performance, transactions, and backend reliability.
Sometimes, progress means pausing, reflecting and allowing what you've learned to settle.
We continue tomorrow

Today's learning: Context Engineering, RAG & Dynamic Filters from @roadmapsh.
Biggest takeaway?
It's not about giving LLMs MORE information, but the RIGHT information at the right time.๐ฉ๐ปโ๐ปโจ

Instead of guessing why my query is slow, I can ask PostgreSQL.
EXPLAIN reveals the query execution plan, helping me investigate table scans, index usage, the work PostgreSQL expects to perform.
Understand before optimizing.
