Day 12 of learning Python. Added Google Auth to improve the sign-in flow. Found a flaw in my email verification system users could spam unlimited emails. Fixed it with a simple rate limit: 60 seconds between requests. Small fix, big security improvement.

Attended the #HireGround2025 Ilorin Career Fair 2025 today biggest lesson? Communication technical skills. HRs said they hire people who communicate clearly and show consistency through personal branding. And confidence? It comes from preparation, not talent. #TechCareers

Day 11 building an auth‑gate in Python. Added email verification: hashed one‑time tokens, short expiry, delete on use, then issue access + refresh (refresh as HttpOnly cookie). Small steps, big security wins. #Python #Security #100DaysOfCode

Devs, what is your workflow: Do you write your documentation before you start coding, or after the project is finished? #SoftwareEngineering #DevLife #coding #webdevelopers

Day 10 #30DaysOfPython. I implemented Refresh Token Reuse Detection. If a token is used after it has been rotated my system assumes it was stolen. The Response: Automatic Security Lockdown. 🚨 It instantly revokes ALL sessions for that user and forces a password reentry. #Python

Day 9 #30DaysOfPython. I've been quiet because I've been building a fortress. I ditched JWTs for refresh tokens. Instead, I implemented Opaque, Hashed Tokens with rotation. Client: HttpOnly Cookie DB: Argon2 Hash Strategy: Security > Convenience #buildinpublic #python #backend

Day 8, #30DaysOfPython. I just built the most important part of a real auth system: Access + Refresh Token rotation. Why? Because you should never force a user to choose between security (15-min tokens) and convenience (3-day tokens). This system gives them both. #buildinpublic

Day 7, #30DaysOfPython: The Auth API is now issuing stateless JWT access tokens! This is a key architectural choice for building scalable, microservice-friendly backends. The server is stateless; the token is the proof. Used python-jose (Python's jsonwebtoken) to handle the sign

Day 6, #30DaysOfPython: The Auth API is functional! Built & tested the full /register and /login flow. I'm using Pydantic for validation, an ORM for clean queries, and argon2 (not bcrypt) for hashing. Why argon2? It's the modern, memory-hard standard for real-world security.

Day 5 of #30DaysOfPython. My FastAPI app is officially connected to my Postgres database. The architecture is working. My laptop battery died. 😅 This is the real #buildinpublic journey. You can't code without power. Back tomorrow to build the endpoint. We go again. #backend

Day 4, #30DaysOfPython. No new features, just 100% debugging. My /register endpoint is broken. I'm neck-deep in FastAPI's dependency injection trying to get my service and repository layers talking. This is the unglamorous, real work of engineering. The bug wins today. I win tomo

Day 3, #30DaysOfPython. 0 features built. 100% progress. Today was all architecture: designing the Postgres schema, defining Pydantic models, & setting up the SOLID interfaces. Building the blueprint is the work. Tomorrow, we build the walls. #buildinpublic #backenddevloper

Day 2 of my #30DaysOfPython. Wrote almost no code. Why? Because I spent the day architecting. I'm building my Auth API with SOLID principles from Day 1, translating my TypeScript patterns to Python's Abstract Base Classes. A day of planning saves a month of debugging. #python

I've spent this year building complex, decoupled systems in Node.js. Today, I'm starting a new #30DaysOfPython challenge. The goal: build a complete "Auth-Gate" API from scratch. I'll be sharing all my progress, challenges, and code. Let's build. #pythonlearningjourney #backend
