Day 64/100 of #100DaysOfCode 🐳🚀

Today I explored Docker Networks & Volumes.

🔗 Networks let containers communicate
💾 Volumes let containers remember data

Realization: Containers alone are temporary.
Networks + Volumes make apps scalable & production-ready 🔥

Day 63/100 of #100DaysOfCode 🚀

Today I finally understood Dockerfiles 🐳

A Dockerfile is basically a recipe for creating the SAME app environment anywhere 🌍

No more:
❌ “Works on my machine”
❌ Dependency chaos
❌ Version mismatch
DevOps journey begins 🔥

Day 62/100 of #100DaysOfCode 🚀

Today I explored Agentic AI 🤖

AI that doesn’t just respond…
It plans, reasons, uses tools, adapts, remembers context, and gets tasks DONE.

We’re moving from:
“AI that answers”
➡️ “AI that acts” 🔥

Day 61/100 of #100DaysOfCode 🐳🔥

Today I finally understood Docker Images vs Containers.

📘 Image = Recipe/Blueprint
🍔 Container = Running meal/app
One image can create multiple containers 🚀

“Build once. Run anywhere.” finally makes sense 💡

Day 60/100 of #100DaysOfCode

🚀Today I explored TypeScript utility types + Zod inference 🔥

✅ Pick
✅ Partial
✅ Readonly
✅ Record
✅ Exclude
✅ Mapped Types
✅ z.infer()

Big realization: Great types don’t just prevent bugs… they design better systems ⚡

Day 59 of #100DaysOfCode: Text-to-SQL Generator 💾

Logic:
Dynamic Schema Extraction ➡️ LLM Translation ➡️ SQLite Execution.

Tech: Python, LangChain, Ollama (DeepSeek-R1 local), Streamlit.

Deterministic SQL with temp=0 for accuracy. 🎯

🚀 Day 58 of #100DaysOfCode

Today I explored AWS ☁️

Learned about EC2, S3, IAM, Route53, Lambda, RDS, DynamoDB, ECS, ECR, Bedrock, SageMaker & more.

Finally understanding how scalable apps are built, deployed, secured, containerized & powered by AI 🔥
#AWS #CloudComputing

Day 57 of #100DaysOfCode 🚀

Today I explored the real power of TypeScript:

• Type Inference vs Annotations
• Interfaces vs Types
• Generics <T>
• Union & Intersection Types

Good types don’t just prevent bugs — they design better systems ⚡

Day 56/100 🚀

LLMs don’t execute tools… they suggest them 🤯

Built tool calling in LangChain:
🧩 Bind tools
🤖 LLM suggests
⚙️ Backend executes

From “just text” → real-world actions 🔥
This is where AI gets serious.

Day 55/100 🚀

Diving into TypeScript basics & finally getting type safety

🔐Arrays ✅ Tuples ✅ Enums ✅

Big one:
⚠️ any = chaos
🛡️ unknown = safety

🔥 Always prefer unknown over any 🔥

JS → TS = guesswork → engineering 💻

Day 54/100 🚀
Built an AI Image Generation App 🍌

Not just prompts → but a full system:
🧠 Smart prompt engineering
⚡ FastAPI backend
🎨 Streamlit UI

From text → ads → try-ons → scenes
AI isn’t just tools anymore…
It’s experiences. 🔥

Day 53/100 🚀

Access Token = 🎟️ short-lived entry
Refresh Token = 🔁 renews access
No localStorage ❌ (XSS risk)
Secure cookies + memory ✅

Mind blown 🤯: OTP isn’t stored—only its hash. Server verifies what it never “knows.”
Security = layers, not features 🔐

[Prabuddha @prabuddhaxdev]

Day 52/100 🚀

Today I explored Tools in LangChain 🔧
→ Built-in tools (plug & play)
→ Custom tools (your logic)
→ Creating tools (function + description = power)
→ Toolkits (bundled capabilities)
LLMs are no longer just chatbots… they ACT ⚡

#100DaysOfCode #AI #LangChain

[Prabuddha @prabuddhaxdev]

Day 51/100 🚀

Learned the backbone of web security:
🔐 Hashing + Salting (no plain passwords)
🛡️ bcrypt (slow = secure)
🍪 Cookies + flags (HttpOnly, Secure, SameSite)
🔑 Tokens for scalable auth
Security isn’t optional. It’s the foundation.

#100DaysOfCode #WebSecurity #WebDev

[Prabuddha @prabuddhaxdev]

Built a YouTube chatbot with LangChain 🤯

🎥 → Transcript → Chunks → Embeddings → FAISS → Retrieval → Prompt → LLM → Answer

It doesn’t “watch”… it understands 🔍

RAG in action = smarter, grounded AI 🚀

🚀 Day 49 of #100DaysOfCode

Learned the difference between:
🔐 Authentication (Who you are)
🛂 Authorization (What you can access)
✅ Validation (Is input correct?)
🔍 Verification (Is it really you?)

Security = Layered Trust ⚡

Day 48/100 🚀

Finally understood RAG 🤯

It’s not about making LLMs smarter…
It’s about giving them the right context at the right time
Index → Retrieve → Augment → Generate

Less hallucination ✅
More accuracy ✅

Building real AI now 💪

🚀 Day 47 #100DaysOfCode

Revised Prisma ORM, SQL Joins & Foreign Keys 💡

INNER, LEFT, RIGHT, FULL JOIN finally make sense 🔥

Big realization: Databases aren’t just storage… they’re about relationships & connections 🤯

Still learning. Still building 🚀

[Prabuddha @prabuddhaxdev]

🚀 Day 46/100: Finally understanding how AI really works 🤯

RAG = AI looks up info before answering 📖
Fine-tuning = making AI a specialist 🎯
Embeddings = words → numbers 🔢

Big lesson: AI is only as smart as the data we give it.

Day 45/100 🚀

Backend concepts finally clicked 🔥
✔ Mongoose = structure for MongoDB
✔ Relationships (1-1, 1-M, M-M)
✔ app.use(express.json()) = req.body works
✔ express.static() = serve files easily

Small concepts. Massive impact.
