Growing Up with Smarter Tools

Rewriting the Role: Developers in the Age of LLMs – Part IV

In the previous post, we explored how coding itself is changing, from syntax to intent, from typing to conducting. Now let’s talk about how we, as developers, grow in that new environment. Because while tools evolve fast, careers, mentorship, and professional growth still depend on something slower and deeper: learning to understand complexity.

The Developer’s New Workflow in the Age of AI

Rewriting the Role: Developers in the Age of LLMs – Part III

In the first two parts of this series, we looked back at the long tradition of technological panic in software development, and how each wave of automation has shifted, not erased, the craft. Then we explored how the fear of “deskilling” misses the point: every time tools get smarter, developers reskill.

Deskilling or Reskilling in the Age of AI

Rewriting the Role: Developers in the Age of LLMs – Part II

In the first part of this series, I looked back at the many times developers were declared obsolete. From Fortran to Java, from punched cards to low-code tools, every new abstraction seemed ready to kill programming, and every time we just moved one level up.

Until They’re Not

Rewriting the Role: Developers in the Age of LLMs – Part I

This article is the first in a series titled Rewriting the Role: Developers in the Age of LLMs, inspired by the talk I gave on November 7, 2025, at the BDX I/O conference in Bordeaux. The talk, and now this series, explores how the developer’s craft evolves when large language models start writing code beside us, and what remains profoundly human in that process.

A few months ago, I published an article introducing MCP servers. Since then, I’ve had the chance to build several of them, experiment with different approaches, and present a talk on the subject at JUG Summer Camp.

That first article was about the what and the why of MCP. This one is a follow-up focused on the how: the practices, patterns, and lessons that make the difference between a brittle prototype and a server you can trust in production.

Introduction: MCP Servers as APIs for LLMs

MCP (Model Context Protocol) servers are to Large Language Models (LLMs) what REST APIs are to applications: structured, standardized ways to interact with external data sources and tools. Like APIs, MCP servers vary significantly in design, from highly generic and flexible solutions to specialized, domain-specific ones.

In this post, we’ll delve deeper into these two approaches—generic versus domain-specific—and explain how thoughtful MCP server design can dramatically improve the usability and efficiency of LLM-powered applications.

What is DevRel?

Developer Relations (DevRel) is about building bridges between tech companies and developers. The goal is to help developers better understand, use, and get the most out of the tools available to them, while also ensuring that companies improve their products through real user feedback.

DevRel typically involves several key activities:

Why not simply use Wordpress?

Hello there, folks!

If you've been following my online adventures on LostInBrittany.org for the past couple of decades, you've seen it evolve from a mishmash of topics to a place where tech reigns supreme. I've used trusty old WordPress for this journey, running everything from my personal blog to corporate platforms like the current OVHcloud blog. Plus, I've set up countless blogs for friends, family, and various groups.

My blog is reborn... again...

Hello to everyone out there – tech enthusiasts, wanderers, artists, and those just plain curious!

If you ventured into the varied pages of LostInBrittany.org in the past, you'd remember a mix of topics – from tech to art, to even optical illusions. That blog was where I combined my love for drawing with the exciting world of digital technology. Over time, priorities shifted, and while the old platform never really went away, its primary focus evolved.
