Modernize, integrate, and operate the systems your business depends on.
Lemraj is a boutique technology consultancy for Dutch and European enterprises that need senior architectural judgement on legacy modernization, complex integration, and Microsoft Azure platforms.
What we do
Legacy modernization
Move off end-of-life stacks and decompose monoliths without freezing the business that depends on them.
Learn moreSystem integration
Connect ERP, CRM, identity, billing, and bespoke systems so data and process actually flow across them.
Learn moreAzure cloud architecture
Landing zones, well-architected workloads, and platform engineering on Microsoft Azure as a managed production environment, not an experiment.
Learn moreArchitecture advisory
Independent architecture reviews, technology selection, and second opinions on in-flight programmes.
Learn moreWhy Lemraj
Versus a Big-4 or large systems integrator
The senior person on the call is the senior person on the keyboard. No partner-led pitch followed by a junior-staffed delivery. No account-management layer between you and the work.
Versus a body-shop or staffing firm
Lemraj sells outcomes, not seats. We will refuse work that isn't a fit. We will scope a delivery and hold ourselves to it, rather than fill an SOW with hours.
Versus an in-house senior hire
A senior architect, available now, scoped around a defined modernization, integration, or platform problem — without the recruitment cycle and without a permanent headcount commitment.
Versus another boutique
Verified Dutch enterprise, insurance, and public-sector engagement history. Deep Microsoft Azure specialisation rather than a multi-cloud generalist stance. An explicit walk-away policy that signals where our quality control sits.

Have a system that has to keep running for the next 10 years?
Most Lemraj engagements end with a documented architecture and delivery plan the client owns and can act on independently of us — and they start with a 30-minute discovery conversation.
