YeabTesfaye/README.md

Hi, I'm Yeabsera (Yeab) Tesefaye 👋🏻

A Full-Stack Developer building production-grade web applications with Next.js and FastAPI. Alongside full-stack work, I conduct authorized penetration testing and am expanding into AI engineering, building LLM-based systems and multi-agent architectures.

🔭 What I'm working on

  • Building full-stack applications for local and international clients as a freelance developer
  • Authoring adversarial evaluation tasks for top-tier LLMs (Claude, GPT, Gemini) to expose reliability and correctness failures
  • Conducting authorized penetration tests on production systems, including IAM and identity platforms
  • Transitioning deeper into AI engineering: RAG pipelines, multi-agent systems, and LLM evaluation

🛠️ Core Stack

  • Frontend: Next.js (App Router), React, TypeScript, Tailwind CSS, shadcn/ui
  • Backend: FastAPI, Python, Node.js, SQLAlchemy (async)
  • Databases: PostgreSQL, Prisma, MongoDB, Redis
  • AI/ML: LLM integration, RAG, CrewAI multi-agent systems, prompt engineering
  • Security: Web app penetration testing, vulnerability analysis, reporting
  • Tools: Docker, Git, Linux
