Concept Informatiebeleid & Automatisering (in short Concept<\/strong>) is the company under which I, Jeroen Wiersma<\/strong><\/a>, offer my services as an independent freelance ICT Infrastructure Architect<\/strong><\/a>.<\/p>

I work in complex enterprise environments and connect management, IT teams and suppliers as a Solution Architect, Deal Manager or Technical Project Leader.<\/p>

With more than 25 years of experience<\/strong><\/a> I support enterprise and (semi) government organizations in designing, analyzing and improving<\/a> complex hybrid cloud environments with a focus on security, availability and cost efficiency \u2014 always with\u00a0security-by-design<\/strong>\u00a0as a starting point.\u00a0<\/p>

I combine strategic and tactical insight with technical depth in infrastructure design, transitions and migrations. In addition, I support organizations in the drafting, assessing and responding to RFPs<\/strong> to select or offer the right partners and solutions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

In a world full of specialists, I bring it all together by combining years of hands-on experience with deep technical knowledge, tactical and strategic insight and a focus on cybersecurity.<\/p>\n

I don\u2019t just design future-proof infrastructures \u2014 I make sure they contribute to a safe, robust and resilient organization in practice. My architectures help:<\/p>\n

\ud83d\udd39 prevent cyber attacks<\/strong> through smart network segmentation, access control and controlled cloud integration
\ud83d\udd39 limit damage<\/strong> in case of incidents through well-thought-out DR and backup strategies<\/p>\n

From cloud migrations to outsourcing, from RFP structuring to disaster recovery: I deliver clear architectures, realistic transition plans and technical guidance through to implementation.<\/p>\n

\ud83d\udd39 I can see the entire playing field<\/strong> without losing details and clearly map out the dependencies
\ud83d\udd39 I connect business, technology and suppliers<\/strong>
\ud83d\udd39 I monitor the feasibility, manageability and security aspects<\/strong>, not only the design
\ud83d\udd39 I deliver what works<\/strong> \u2014 substantiated, scalable and resilient to cyber threats<\/p>\n

No castles in the air. No over-engineering.
Clarity, feasibility and results.<\/p>\n<\/blockquote>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

From analysis to implementation \u2014 I am not an advisor on the sidelines, but a technical leader who takes responsibility for realization.<\/p>

\ud83d\udd39 In-depth advice, but always actionable.<\/strong>
I translate strategic goals into concrete infrastructure solutions \u2014 with an eye for costs, risks, and feasibility.<\/p>

\ud83d\udd39 From design to implementation.<\/strong>
I not only deliver a plan, I also lead the execution: the technical design, coordination of the implementation and coordination with suppliers and IT teams.<\/p>

\ud83d\udd39 Guiding role in transitions and transformations.<\/strong>
As a Solution Architect or Technical Project Manager, I oversee the content. I manage specialists, coordinate across multiple vendors, and oversee security, availability, and timelines.<\/p>

\ud83d\udccc Result:<\/strong> a future-proof, securely designed infrastructure that not only looks good on paper, but also works in practice.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
