Please note that my resume is not strictly chronological, as I have worked on various projects and held different responsibilities for multiple clients over the years, often concurrently

Over the years, I have worked with multiple clients across the private sector, real estate, healthcare, and global industries, focusing on Microsoft 365, hybrid IT environments, and innovative cloud-based solutions. My work has consistently involved designing and implementing scalable, secure, and efficient IT infrastructures tailored to meet the unique needs of each client.

For a client in the real estate sector, I designed and built a managed workplace using Microsoft Intune. Leveraging Autopilot in Self-Driven mode combined with shared PC settings, I created a flexible pool of devices for their consultants. Applications were deployed using native packaging mechanisms and platforms like Chocolatey, ensuring streamlined management and user-friendly deployment.

In the healthcare industry, I supported a leading European company specializing in hypothermia by developing a centralized log analysis data platform hosted in the Microsoft Azure Cloud (Azure SQL). This platform aggregated device-specific sensor information from custom data sources via Python and Power Automate. I also created Power BI dashboards to visualize data insights and enabled advanced search capabilities within the data, empowering the client with actionable intelligence.

In recent years, I have focused extensively on identity and access management, resolving complex challenges with Microsoft Entra ID (Azure AD) and integrating on-premises Active Directory with cloud-based solutions. My work included designing and deploying Azure Virtual Machines, Virtual Networks, and Azure Storage solutions to support secure, scalable, and cost-effective IT environments. I also configured Azure Virtual Network (VNet) peering, VPN gateways, and Azure Firewall to establish high-performance connectivity between on-premises systems and Azure.

A key part of my role has been aligning IT systems with business objectives by centralizing identity and access management while ensuring compliance with industry standards such as GDPR, ISO 27001, NEN, and NIST. To enhance efficiency, I developed workflows and automation using Power Automate and Azure Logic Apps, significantly reducing manual effort and streamlining operations.  

As a solution architect, I delivered end-to-end designs for Azure-based environments, incorporating services such as Azure Key Vault, Azure Functions, and Azure Monitor to enhance security, scalability, and visibility. I deployed and managed Microsoft Intune to ensure device compliance, implement endpoint protection, and support mobile device management in hybrid environments.

These experiences highlight my ability to work across diverse industries and projects, whether developing innovative cloud-based platforms, optimizing hybrid environments, or driving digital transformation. My collaborative approach and technical expertise have consistently delivered scalable solutions that align with business goals and enhance operational excellence.

As the Technical Lead overseeing integrations and rebrands following multiple acquisitions, I reported directly to the board, playing a critical role in unifying diverse entities into a cohesive global brand. My responsibilities encompassed managing complex identity and access management challenges, harmonizing application landscapes, and streamlining essential business processes.

A significant achievement in this role was the design and implementation of a multi-ecosystem solution that seamlessly integrated both Google and Microsoft platforms. Leveraging Azure’s robust infrastructure and Microsoft 365’s collaborative tools, alongside Google technologies, I ensured a comprehensive and flexible approach to integration. This solution strategically aligned technology with business objectives, enabling smoother operations and greater efficiency across the organization.

My expertise in cloud technologies, particularly Azure and Microsoft 365, combined with my proficiency in Google tools, was instrumental in driving this transformation. The result was a unified and efficient global identity that strengthened the organization’s position in a competitive and dynamic business landscape.

During this period, I was also considered as a runner-up for the role of CTO. However, due to a shift in the company’s global strategy, the role was ultimately assigned to the team in India. Despite this, my direct contributions as Technical Lead were pivotal in shaping the organization’s technological direction and establishing a strong foundation for its future growth.

For the PayComplete Technology Group, I worked on and off over the years, with a specific period lasting five years being a almost full-time engagement as IT Architect and Lead Technical Consultant. Reporting directly to the CTO, I assisted leading a team of 12 IT professionals located across the globe, supporting a total infrastructure of 1,800 users across 14 international locations. My primary responsibility was driving their digital transformation strategy, which included major projects such as Active Directory migrations, cloud consolidations, and process optimizations.

One of the most critical initiatives was consolidating six disparate Active Directories and two Microsoft 365 tenants into a unified global Microsoft cloud solution. This involved standardizing all corporate identities and email addresses into a consistent global format. The Dutch environment, already operating in a hybrid Microsoft 365 setup, was chosen as the target architecture. I oversaw the migration of all other identities into this infrastructure while consulting on Azure AD sign-in methods and addressing security implications. To ensure robust security, I regularly provided insights using security dashboards such as Cloud App Security, Microsoft Defender, and Azure Sentinel. The technologies utilized for this project included Microsoft Azure Active Directory, Azure AD Connect, on-premises Active Directory (various versions), Exchange Server, PowerShell scripting for custom solutions, and migration tools like BitTitan and ShareGate.

Another significant project was the ERP implementation and infrastructure redesign. The company decided to centralize its warehouses and production facilities in Poland while implementing a new ERP system, Infor M3. I consulted on the target architecture, evaluating PaaS, IaaS, and on-premises infrastructure options. Ultimately, we opted for a full cloud setup, for which I handled Azure sizing, cost optimization (including reservations), and infrastructure design. This included building PROD and TEST environments consisting of 14 application servers, six SQL servers, and a shared ADFS farm, with applications published through redundant KEMP load balancers. Key technologies used in this project included Azure Virtual Machines, Azure Networking Security Groups, Azure Firewall, Azure SQL, ADFS, Azure load balancers, and KEMP load balancers.

I also led an email security project to implement secure email transport and gain transport security insights for over 60 domains. This involved technologies such as Exchange Online ATP, SPF, DKIM, DMARC, and DMARCIAN for reporting and monitoring.

In addition, I spearheaded a Windows Virtual Desktop (WVD) pilot project for the company’s Hong Kong office. We evaluated the initial version of WVD and successfully implemented the second version, managing user profiles with FSLogix and exploring MSIX app attach capabilities to optimize application delivery.

Another key achievement was optimizing the employee onboarding and offboarding process by designing and implementing an HR-operated solution to reduce the IT department's workload. Working with tools such as Adaxes, Power Automate, and Azure Active Directory, I translated business processes into automated workflows, ensuring a streamlined and efficient solution for HR.

Throughout my tenure, I played an integral role in multiple transformative projects, aligning IT strategy with business goals and delivering scalable, secure, and efficient solutions.

Over a 12-year period, I worked with Marlink on an ad hoc basis across various projects, serving as a trusted IT partner in their transformation journey. During a specific period, I stepped in as interim Lead Engineer to cover for an internal employee on sick leave.

Throughout my engagement, I played a pivotal role in supporting Marlink’s growth from a small organization with 25 users to a global leader in satellite communications with over 1,200 users across multiple international locations. Over the years, the company underwent several acquisitions, including by France Telecom, Vizada, and later Marlink itself. These transitions required multiple Active Directory consolidations and infrastructure reorganizations, where I provided expertise as a lead engineer and architect to ensure smooth integration and modernization.

I also guided Marlink in their initial steps toward adopting Microsoft Cloud technologies, eventually shaping their IT strategy into a cloud-only and capacity-on-demand model to meet evolving business needs.
