Staff-Level Engineering Consulting & Mentoring

Is your engineering environment feeling "small or slow"? Are your tools, pipelines, and architecture struggling to keep up with your team's growth?

I help engineering organizations scale their platforms, people, and processes. As a Staff Engineer who has scaled systems for hundreds of developers at leboncoin.fr and Kleinanzeigen, I solve the complex bottlenecks in platform engineering, developer experience (DevEx), and systems architecture.

My Services

1. Platform & DevEx Acceleration

  • What it is: A top-to-bottom audit and rebuild of your development and deployment pipeline. We find what's "slow" and make it fast.
  • What you deliver: A pragmatic, actionable roadmap to fix your CI/CD, testing, and infrastructure bottlenecks. I'll apply the same principles I used at leboncoin.fr to:
    • Migrate your entire CI/CD from legacy systems (like Travis) to modern platforms (like GitHub Actions).
    • Crush CI times from 1-2 hours down to under 10 minutes.
    • Optimize infrastructure, in one case reducing production pods from ~500 to ~150.
  • Best for: Teams held back by slow builds, flaky tests, and a high Mean Lead Time for Changes (MLTC).

2. Modern Architecture & Migration Strategy

  • What it is: A strategic plan to scale your architecture and your engineering organization together.
  • What you deliver: A clear path forward, whether it's designing a scalable monorepo or migrating a legacy monolith. I'm currently leading this at Kleinanzeigen, migrating a jQuery/Java SpringBoot system to a Node.js, Astro, and React stack, resulting in a 5x improvement in development speed for the teams involved.
  • Best for: Organizations struggling with a monolith, scaling to 100+ engineers, or needing to design a high-performing monorepo for shared packages and micro-frontends.

3. Staff+ & Neurodiversity Mentorship

  • What it is: A 1-on-1 mentorship program for engineers and leaders. This program has two tracks:
    1. Technical Leadership: A structured growth plan for Senior engineers on the path to Staff/Principal. We focus on technical strategy, architectural vision, and cross-team influence.
    2. Navigating the Workplace: Dedicated, empathetic coaching for neurodivergent (ND) professionals. If you are struggling with your work environment and would like the perspective of someone who has navigated it, I am here to help.
  • Best for: Ambitious engineers, new Staff-level leaders, and any neurodivergent professional in tech seeking confidential guidance.

Who This Is For

I provide the most value to...

  • CTOs or VPs of Engineering at scaling companies whose teams are "feeling slow" and blocked by their platform.
  • Engineering Managers or Directors who need a concrete plan for a complex, large-scale migration (e.g., monolith to micro-frontends).
  • Senior Engineers on the path to Staff who need a mentor to guide them.
  • Neurodivergent Professionals in tech who would like coaching from someone with shared experience.

My Consulting Philosophy: Pragmatism over Dogma

My approach is built on one core idea: "Change is Requirement #0."

I don't believe in "best practices" that don't fit your context. As a self-taught engineer from a humanities background, I see code as prose and architecture as a story.

My job isn't to force my opinions. It's to act as a teacher and a problem-solver. I'll become a historian of your system, understand why it was built, and give your team the context, real-world experience, and confidence to make the best decision for your specific case.
