Stopping disguised bot traffic at the edge
- Challenge
- A high-traffic domain was flooded by unknown bots that kept rotating their IP, user agent and location, so blocking by any single attribute didn't work.
- Approach
- I built bot-filter rules in Azure Front Door WAF. A rate-limiting rule catches repeated hits on the same URL, and suspicious requests get a bot challenge first. Anyone who passes gets through, and normal visitors are never challenged.
- Result
- Requests cut from 36M to 20M per year, saving €150K/year.

CI/CD · Infrastructure as Code
Repeatable cloud deployments
- Challenge
- Classic, click-configured pipelines and hand-built environments made releases slow and hard to reproduce.
- Approach
- YAML pipelines (build → UAT → Production) with pre-release checks for PII, disallowed plugins and stray SQL dumps. Terraform provisions App Service with slots, MySQL, Application Insights and Storage. Secrets stay in pipeline variable groups.
- Result
- +50% pipeline efficiency from the CI/CD transformation, and IaC adopted with Terraform.

L1
rag-docs-assistant ↗
A RAG API over Markdown docs. Chunking and a retrieval funnel find the passages; guardrails block prompt injection and mask PII; medium-confidence answers go to a human review queue; quality is measured with golden sets and an LLM judge.

llm-ticket-analyzer ↗
Support-ticket triage with LLM structured output (category, urgency, summary), validated by Pydantic. A mock mode keeps tests free of API cost.
