About Naji

I am a software artisan with a strong business acumen, sensitive to the user experience of my creations.

I have led solo or small team projects with cross-functional roles: engineering, product, UX.
I am a Swiss Army knife who builds quickly and can challenge you on the ROI of the technical solutions you are considering.
I deliver value increments in short cycles, without two-week sprints.

I have fully adopted the latest AI tools and am capable of delivering end-to-end agentic solutions (DeepAgents, Claude and OpenAI Agent SDKs, PromptOps, context engineering, RAG...) with a clear-eyed approach grounded in business reality.

Experience

  • TechDoc0
    Co-founder
    SOFTWARE PUBLISHING
    September 2025 - November 2025 (2 months)
    Rennes, France
    Startup project with 1 partner, aborted after 1 month of work.
    TechDoc0 addresses a recurring pain point for software development teams: maintaining up-to-date technical documentation.
    Missing/obsolete technical documentation → slowed developer onboarding → over-solicitation of senior profiles → slowed time-to-feature.
    By generating quality technical documentation from existing codebases, our solution accelerates the delivery of high-value products.

    - market research
    - user discovery with software industry players: CEOs, CTOs, digital agency executives
    - product and pricing strategy; landing page
    - LLM provider cost analysis
    - proof of concept: semantic processing of a codebase using LangChain/LangGraph + LLMs, deployment on VPS; context engineering

    Project initiated during SaaS camp #2, a one-week entrepreneurship camp aimed at creating a SaaS and signing a first customer during the camp.
