Project Overview
This project was carried out for a regional grid operator in the German energy sector, responsible for critical infrastructure and operating within a highly regulated environment.
I worked as a Fullstack Engineer | .NET & Dynamics 365 within a Lead Consultant engagement at Acando / CGI, contributing to a greenfield development initiative building customer-facing self-service portals from the ground up.
The project focused on designing and developing B2C and B2B self-service portals supporting photovoltaic system onboarding, grid connection requests, and related energy-sector business processes — alongside Dynamics 365 customization and CRM integration.
