Open to Lead Developer roles

Adrien Deprez

Lead Developer · Senior full stack engineer

9 years of full stack work in retail and SaaS · Lille, France

I've been building software for 9 years, mostly for retail (Leroy Merlin, ADEO, Norauto) and SaaS. I take a product all the way: I work out the need with the business, design the architecture, write the front end and the back end, then look after the release and the monitoring. I'm now looking for a Lead Developer role: designing systems, supporting a team and keeping the quality of its work high.

How I work

  1. 01

    Solving business problems

    To me, software is first a tool for the business. I like to follow a problem from start to finish: talk it through with users, gather the need, design the solution, then build it and keep it running in production.

    1. Talks and needs
    2. Design
    3. Architecture
    4. Back and front end
    5. Ops and CI/CD
    6. Industrialisation
    7. Monitoring

  2. 02

    Craft and pragmatism

    I care about software craftsmanship, clean code and the Pragmatic Programmer mindset. I try to do as little as possible, as cleanly as possible, for the most result. I apply these principles case by case, not as dogma.

  3. 03

    Growing the team

    I share what I know: documentation, pair programming, kind code reviews, careful onboarding. The goal is a team that ships well even when I'm not around.

  4. 04

    Deciding on facts

    When facing a technical choice, I compare a few options against explicit criteria: need, maintenance cost, reversibility. If we're still unsure, a short POC settles it, and the decision goes into an ADR.

    • Appointment orchestration API: it connects the appointment-booking SaaS to ADEO's systems, with GDPR compliance, notifications and a data pipeline.
    • Customer Project repository: the API that is the source of truth for the customer project lifecycle (qualifications, estimates, appointments) across the ecosystem.
    • Datadog dashboards and BigQuery usage analysis that feed product decisions.
    • Set up CI/CD pipelines, automated tests and linters for the team.
