Full Stack Developer

Green Dev · Tilkeo · Chalon-sur-Saône

I contributed to the group's internal ERP, designed to digitise energy-renovation processes across Tilkeo entities. The platform's ambition was to support the full customer journey, from prospect discovery through project delivery and after-sales service (SAV).

01 — BUSINESS CONTEXT

One ERP for the
renovation journey.

This work was broader than one standalone tool. The internal platform aimed to connect teams and digitise the operational workflow around energy-renovation projects: prospecting, customer and case follow-up, preparation, works, completion and after-sales.

ONE FEATURE AMONG MANY

Tik’aide

03 — TIK’AIDE EXAMPLE

One feature within
the wider ERP.

Tik’aide estimates renovation grants based on multiple household parameters. The documented screen brings household size, income ceilings and MPR / CEE amounts together for advisers. Django / Python, Vue.js and MySQL were used across backend, interface and data work; help content could also be generated as PDF with ReportLab.
