Open to new collaborations

I write code and teach it.

I'm Manfredi, a full-stack React, TypeScript and Node.js developer in Palermo. I work for software houses and agencies, inside their teams and projects, and I teach programming at coding academies.

Who I work with

Two ways to work together.

Software houses and agencies that need one more developer on their clients’ projects. Academies looking for someone who teaches the craft while practising it every day.

For software houses & agencies

One more developer on your team, from day one.

  • Autonomy on tasksYou assign a task, I give you a clear estimate and deliver it on my own, with regular updates.
  • Full-stack JavaScript & TypeScriptReact frontends, Node.js and Express backends, SQL and NoSQL databases. Mobile apps with React Native.
  • AI integrationsFor clients asking for AI features: assistants, RAG systems and LLM-based automations inside existing applications.
  • Inside your tools, white-label welcomeI work in your repository, with your conventions and your project tools.

For academies & training

I teach what I do every day.

  • Lessons and mentoringLive lessons, one-to-one mentoring and group tutoring, online or in person in Palermo.
  • Code reviews on projectsReviews of student code with comments that explain the why, not just what to change. Coordination of small development teams.
  • SubjectsHTML, CSS, JavaScript, TypeScript, React, Node.js and Express, databases, and using AI in development.
  • From a working developerI bring real problems from the projects I work on into class, not just exercises.
