✅ Strategic certification order: AWS Cloud Practitioner (entry level) → AWS Solutions Architect Associate → AWS Solutions Architect Professional. This progression gradually strengthens your salary negotiation leverage. Azure certifications are particularly valued in the financial sector (KBC, ING, etc.).
After a Master's in Computer Science at KU Leuven and three AWS certifications, the initial salary offer was €52,000. After renegotiating based on the certifications, it rose to €64,000. Three years later, with the Azure Expert certification added, I received a senior offer of €85,000.

⚖️ Employee vs Freelance — Which Is More Advantageous?
In Belgium's IT market, the freelance status (Zelfstandige / Indépendant) is very common. Particularly at the Architect and Senior level, freelancers often earn significantly more than salaried employees.
Freelance Day Rates
※ Based on 220 working days/year. Max Architect annual income: €264,000.
💼 Employee (Salarié / Loondienst)
- Stable monthly salary — 13th month and bonus included
- Social security and pension contributions automatic
- Benefits: car leasing, meal vouchers, eco-vouchers
- Sick leave, parental leave, paid holidays guaranteed
- Training and certification costs covered by employer
- Professional network and supported career development
🚀 Freelance (Zelfstandige / Indépendant)
- Day rate €350~1,200 — up to 2× the employee salary
- Freedom to choose projects and clients
- Tax optimisation possible (incorporation of a company)
- Varied experiences strengthen the portfolio
- Social contributions and pension at own expense
- No income during gaps between contracts
| Level | Employee Salary (GROSS) | Freelance Income (est.) | Difference |
|---|
| Junior level |
€36,000~50,000 |
€77,000~110,000 |
+€40,000~60,000 |
| Senior level |

€89,000~140,000 |

🤖 AI/ML Premium — Belgium's AI Talent Shortage
The biggest shift in Belgium's IT market between 2024 and 2026 is the explosive demand for AI/ML specialists. Profiles with expertise in generative AI (GenAI), large language model (LLM) development and MLOps skills earn +15 to 25% more than standard developers.
