How does web scraping work?
Web scraping is the structured extraction of data from websites, done ethically and in compliance with robots.txt and terms of use. I deliver it as a reliable, testable, and scalable component of your system, not just a script.
Do you provide post-development support?
Yes. Every project includes post delivery support, 1 week for Basic, 2 weeks for Medium, and 4 weeks for Advanced packages, with optional extended maintenance for long term stability.
What technologies do you use?
I primarily use Python (FastAPI, Django) and React, along with Docker, CI/CD, and testing frameworks, always aligned with Clean Architecture and DDD.
For AI, I integrate Generative AI and Large Language Models (LLMs) from providers such as Hugging Face, AWS Bedrock, OpenRouter as well as client-provided custom LLMs using secure, mockable, production-ready patterns. I do not fine-tune models; I make them work reliably in real systems.
Can I get on-demand support?
Absolutely. If you need help with bugs, updates, or small improvements without a monthly commitment, I offer an On Demand Support Block: $150 for up to 5 hours of focused work, delivered within 5 business days.
