Available for missions from 1 January 2027 · 4 days a week

IT consultant · .NET engineer · lecturer

I build rules engines with their own little language. Oracle syncs that never go down. domain models that speak the business. integration platforms that ship in days, not months. commands that never pretend to be queries. microservices out of tired monoliths.

About

Youssef El Boujeddaini smiling, in a light sweater, in warm tones

Curious about computers since the age of 6, and still learning every day.

I'm a full-stack .NET engineer with 4+ years of experience building enterprise software for clients such as CNH, AkzoNobel and Delen Private Bank, including SAP, Azure IoT and SCADA integrations.

I'm strongest in C#, .NET 8 and Oracle PL/SQL, with a focus on domain-driven design and clean, maintainable architecture.

Today I work as a freelance consultant, and as a lecturer at KdG I teach programming and web technology to computer-science students.

Experience: 4+ years
Based in: Sint-Niklaas, Belgium
Languages: 6, from Dutch to German
Also: Lecturer at KdG

Supplier sourcing platform

Full-stack developer 2025 – now

Two internal portals for supplier data and sourcing projects, on .NET 8 and Oracle.
The challenge

Supplier information and sourcing progress needed a home: one tool to digitise and organise supplier data, another to monitor project milestones and sourcing activities.

What I did
- Modelled the procurement finance domain (NPV, EAC) with DDD and CQS.
- Built a configurable rules engine with a custom DSL.
- Routed data access through Oracle stored procedures.
- Synced data from Databricks into Oracle in batch jobs, with zero-downtime partition exchange.

An IoT platform that ships integrations in days

Technical account manager 2024 – 2025

Shared building blocks that made new integrations cheap and fast.
The challenge

The client constantly needed new integrations, and each one was expensive to build.

- Supported the client in integration decisions.
The outcome

Development time and cost fell by 40%, and delivery time went from 3 months to less than a week.
