Nisanthan Sivarajah
Last position:
Business Intelligence Consultant (freelance) at NBIC – Nisanthan BI Consulting
Advising companies on building, migrating and optimising BI and reporting landscapes (Power BI, SQL, Python, ETL)
5 client engagements in real estate and finance since 05/2025: taking over and stabilising existing reporting, automating recurring standard and management reports, building cash-flow models
Proposal and feasibility assessments for BI and reporting projects
Using AI-assisted development (Claude Code) to accelerate automation, tooling and web/app development
Custom ERP system
Problem: A client's core processes ran on scattered, siloed Excel files with no central data storage – error-prone, hard to scale and impossible to analyse end-to-end.
Approach: Captured the business processes and requirements, modelled the data and developed iteratively together with the business team.
Implementation: Built a tailored, web-based ERP system with a central database, role-based modules and automated reporting – delivered using AI-assisted development in Claude Code.
Timesheet app
Starting point: Time tracking based on an overgrown, macro-heavy Excel template – maintenance-intensive, single-user and error-prone.
Implementation: Migrated all functionality and VBA macros into a standalone web app with central data storage, multi-user support and automated reporting.
Cash-flow modelling
Starting point: The existing cash-flow model covered standing investments only; project developments were missing from steering.
Implementation: Built and extended the CF model to include project-development cash flows.
Optimisation: Reviewed and optimised existing CF models and expanded the KPI outputs for reporting and steering.

About the technology
Core use
Windows Server is the Microsoft platform many companies use to run internal services, identity, and shared infrastructure. It supports domain control, file access, application hosting, and central policy management for mixed office and remote teams.
Typical work
- Active Directory and user access
- Group Policy and security baselines
- File, print, and network services
- Hyper-V and virtual server setups
- Patch planning and server upgrades
Skills that matter
Strong professionals know Windows administration, PowerShell, networking, DNS, DHCP, and backup and recovery. They also understand how Microsoft 365, Entra ID, and on-prem systems fit together in a stable hybrid setup.
When companies bring help
Teams call in freelance expertise for migrations, broken logins, slow file shares, server hardening, or version upgrades. It is also common when internal staff need extra capacity for a rollout, a cleanup, or a short change window.
What strong experts do
Good experts document every change, test rollback paths, and work cleanly with existing naming, permissions, and service accounts. They spot risks early, keep systems readable, and avoid quick fixes that create new support issues later.
Berlin projects
In Berlin, Windows Server work often supports offices, professional services, logistics, and other companies that need dependable internal systems. Freelance specialists can work on-site for sensitive changes or remotely for planning, scripting, and day-to-day support.
Frequently asked questions
Curious about Windows Server? Here are the answers that come up again and again.
Windows Server is used to run internal services that employees rely on every day. Common tasks include identity management, shared storage, policy control, and hosting business applications on a Microsoft-based server stack.
Windows Server fits best when a company depends on Microsoft tools such as Active Directory, Group Policy, or Windows-based application hosting. Linux is often chosen for different application stacks, but many businesses run both side by side in a hybrid setup.
A strong Windows Server specialist usually brings PowerShell, DNS, DHCP, Active Directory, networking, and backup and recovery knowledge. In many projects, Microsoft 365 and Entra ID experience also matter because on-prem and cloud systems often need to work together.
The right level depends on the task. A routine user and policy issue may need a focused specialist, while a domain migration, security hardening effort, or upgrade path usually calls for someone who has handled similar environments before.
Windows Server work can often be done remotely when the task involves planning, scripting, monitoring, or standard support. On-site presence in Berlin is helpful for sensitive change windows, hardware-related work, or when access rules require hands-on support.
Windows Server is the broader server platform, while Active Directory is one of the core services that often runs on it. A company may need someone who can manage both, especially when identity, permissions, and login issues are part of the project.
Look for clear examples of server changes, upgrade planning, access control work, and recovery handling. A strong Windows Server professional explains trade-offs, tests changes carefully, and writes clean documentation that others can use after the handover.
Windows Server expertise is often needed for migrations, domain restructuring, file service fixes, patching, virtualization, and security cleanup. It also comes up when a company needs a short-term specialist to stabilize an environment before an internal team takes over.
