Shipped another big update to Sentinel_api today 🚀

Authentication is now taking shape with JWT auth, API key management, Redis, PostgreSQL, and more. One step closer to a productionready backend.

Building in public. 💻#buildinpublic #fastapi #fullstackengineer

[@NullArchitect🚀👨‍💻 @NullArchitect05]

Sentinel is a rate limiting and API monitoring platform I'm building with FastAPI.

The goal is to build something that reflects how production backend systems are designed, not just another CRUD project.

[@NullArchitect🚀👨‍💻 @NullArchitect05]

The biggest lesson today wasn't writing code......it was testing it.

Fixed Redis configuration, PostgreSQL connection issues, and authentication setup. That's the kind of work that turns a project into something reliable.

[@NullArchitect🚀👨‍💻 @NullArchitect05]

Today's work included:

JWT access & refresh tokens
API key generation & revocation
Password change
User profile endpoint
Logout & token refresh
Redis + PostgreSQL integration
End to end authentication testing

@cviklihamar Thank you so much...still building

[@NullArchitect🚀👨‍💻 @NullArchitect05]

Building something I'm proud of.

Another big update shipped for Sentinel today. 🚀

Slowly turning it into a production-ready platform.

If you're looking for a Full-Stack Developer & Analytics Engineer to build APIs, dashboards, automation, or data platforms, my DMs are open.

Always happy to discuss freelance and long-term collaborations. 🤝

[@NullArchitect🚀👨‍💻 @NullArchitect05]

The goal isn't just another API.

I'm building Sentinel into a platform for API security, monitoring, analytics, and developer tooling one feature at a time.

[@NullArchitect🚀👨‍💻 @NullArchitect05]

Focused on strengthening Sentinel's security layer this sprint:

✅ JWT authentication
✅ Refresh tokens
✅ Secure API keys
✅ Password hashing (bcrypt)
✅ Cleaner project architecture

Next: rate limiting, monitoring & analytics.

[@NullArchitect🚀👨‍💻 @NullArchitect05]

Finished with the Pydantic schemas for boundary validation. Separation of concerns is key: never mix incoming payloads with outgoing responses. Next up: Cryptography and hashing layer. 🔐🚀 #Backend #FastAPI #PostgreSQL

[@NullArchitect🚀👨‍💻 @NullArchitect05]

Stress-tested the Redis rate-limiter for Sentinel today. The 429 circuit breaker fired perfectly under load. ✅ IP tracking is locked in, but enterprise SaaS requires real API Keys. Today, I migrated the core architecture to a persistent state. 🧵👇

[@NullArchitect🚀👨‍💻 @NullArchitect05]

Built the SQLAlchemy models. Strict 1-to-Many relationships between Users and API Keys. Used UUIDs to prevent IDOR attacks and cascading deletes to stop orphan data. 🗄️

[@NullArchitect🚀👨‍💻 @NullArchitect05]

Set up a heavy-duty PostgreSQL async connection pool using FastAPI and asyncpg. Configured 20 hot background connections so the database never bottlenecks under traffic spikes. ⚡️

[@NullArchitect🚀👨‍💻 @NullArchitect05]

Today as a Backend Engineer:
1. ​Built a high-performance Redis service for my API.
2. ​Implemented async connection pooling to handle spikes.
3.​Added "Fail-Closed" safety for system stability.
4.​Hooked into FastAPI lifecycle.
​DM to connect! 🛠️ #buildinpublic #fastapi
