Method

How I work.

Every engagement follows roughly the same steps.

  1. Understand

    The business, the constraints and the team, before writing any code. We agree on the goal.

  2. Build

    Step-by-step development, with code reviews and tests, working alongside your team.

About

A developer since 2009, freelance today.

I'm Kevin Nalinne. I've been building software since 2009 and kept coding as I took on architect and tech lead roles. I work independently, mostly with B2B companies, on design as well as development.

I'm also a trainer, which helps me explain technical topics simply.
