MKS

Hello, I am Mert Kadir Seçilmiş.

I have spent years at the heart of organisations' technology infrastructure. Building an environment where systems, networks and business applications run both smoothly and securely is, for me, the most rewarding part of the job. From ERP and CRM projects to Microsoft 365 transformations, I have brought many initiatives to life together with strong teams. Lately my focus has shifted to data and artificial intelligence: using modern data platforms to reveal the story behind the numbers, and taking AI beyond experimentation to make it a force that genuinely transforms how organisations work.

about me

Preparing today's infrastructure for tomorrow's needs

Technology is changing faster than ever, and an organisation's ability to keep pace depends on building flexible structures on solid foundations. Throughout my career, I have kept this balance by bridging infrastructure, security and enterprise applications. Today data and artificial intelligence are at the centre of my interest: creating real value from existing systems and bringing new technologies into the organisation as an opportunity rather than a risk. Managing change is, for me, the most meaningful part of the job.

Network Security

Role:

Project Lead

Area:

Network Security

Technologies:

FortiGate, Sophos

Scope:

Corporate network

The existing firewall protecting the organisation's network was struggling to keep up with growing traffic and security requirements. The move to a next-generation platform had to be planned and delivered without disrupting daily operations.

Existing rules were reviewed one by one, simplified and migrated to the new platform. The cutover was completed in planned off-hours windows, resulting in a network security setup that is more visible, easier to manage and stronger against current threats.
