Writings & Notes

Engineering breakdowns, deployment lessons, AI experiments, and everything learned while building real systems.

Building Scalable Web Scrapers with Flask and Celery

How I built a multi-source scraping system that handles rate limiting, deduplication, and real-time notifications.

Everything I learned deploying Flask and Next.js applications on Railway — from Docker setup to CI/CD pipelines.

Experiments with Ollama, LangChain, and building practical AI tools that run entirely on local hardware.

Production-tested patterns for structuring Flask applications — from blueprints to service layers and background tasks.

Lessons from building automation systems that need to run continuously, handle failures gracefully, and scale horizontally.
