Hi, I'm
Kateleen Issa
A perpetually curious full-stack developer building digital experiences.
About
A bit about me.
I'm a full-stack developer, but the backend is where I do my best work. For the past few years, I've contributed to production software at a large enterprise, developing new features and resolving issues in the systems that teams build on and users depend on. Outside of work, I build to learn, getting hands-on with new technologies and turn ideas into working software. Lately that has meant applications that put AI to practical use, at the intersection of dependable engineering and intelligent, user-facing products.
The Why.
There's real satisfaction in working a problem until it clicks, with each one still teaching me something new, keeping the work interesting. What drives me is impact. I want to help a company succeed by building software that's reliable, solves the right problems, and creates real value for its users and the business. That's what I look for in the work I take on, and what I aim to bring to a team.

Post-Mortem Pilot
AI incident-analysis knowledge base
Backend | APICodeAn engineering incident-analysis tool that turns scattered post-mortems into a searchable knowledge base. Paste an error log or upload a document and vector similarity search surfaces the past incidents most like the one you're debugging. LangChain and the OpenAI API restructure rough notes into consistent write-ups, KMeans clustering with LLM summarization surfaces recurring failure patterns, and Celery and Redis keep ingestion off the request path. Containerized with Docker and shipped through a GitHub Actions CI/CD pipeline.
