Abbass Jaber
Lead Full Stack Engineer.

I build scalable products — backend to pixel. Six years shipping production software across React, Angular, Node.js, and .NET, with an AI-native engineering practice that treats LLMs as real teammates.

01 / About

A senior generalist with a backend-first instinct and frontend craft.

I'm a Lead Full Stack Engineer based in Beirut. I've spent the last six years shipping production software end-to-end — React and Angular on the frontend, .NET and Node on the backend — across SaaS startups and enterprise teams in MENA and globally.

Lately, I'm obsessed with AI-native engineering: building codebases that read well to LLMs, and workflows where Claude Code, Cursor, and MCP are real collaborators — not novelties. I lead by example, not slide deck.

When I'm not shipping, I'm reading systems-design papers, sketching architecture, or arguing REST vs. GraphQL with whoever will argue back.

04 / AI-Native Engineering

I treat the LLM as a real teammate — not a snippet generator.

Claude Code, Cursor, and MCP aren't a productivity hack on the side of my workflow — they are the workflow. I write codebases that read well to models, ship custom system prompts as artifacts, and design tools the LLM can actually call.

It's a deliberate practice: legible state, typed boundaries, opinionated repo READMEs, and eval harnesses that catch regressions before the team does.

Tooling
Claude Code · Cursor
Daily-driver IDEs. The model is in the loop on every non-trivial change.
Protocol
MCP servers
Custom servers expose engineering ops as typed, callable tools.
Prompts
Versioned system prompts
Treated as code — reviewed, tested, and shipped behind feature flags.
Codebase
LLM-legible repos
READMEs, type signatures, and module boundaries that read well to a model.
