Senior software consulting and technical leadership for organisations where the stakes are real and experience genuinely changes the outcome.
Start a conversationNearly two decades designing Estonia's critical digital infrastructure. Now available to organisations that need that same level of care applied to their hardest problems.
CodeHouse works on high-stakes problems where experience genuinely changes the outcome — platforms that cannot fail, migrations under pressure, and organisations navigating the gap between good intentions and production-grade outcomes.
"The hardest problems aren't technical. They're organisational, political, and human. Good architecture solves all three at once."
CodeHouse is the independent practice of Markus Karileet, a solution architect with close to twenty years designing the systems that run Estonia's digital state — platforms processing hundreds of millions in public funds, serving millions of citizens, where failure carries real consequences.
The practice focuses on high-complexity engagements where seniority changes the outcome. Alongside client work, Markus contributes through university teaching, open-source tooling, and direct writing on AI implementation in production environments.
