About

I'm a Solution Engineer at Microsoft in Espoo. I help customers work out where AI fits in their business, then build the demos and architecture that show it working: AI agents, API integrations and workflow automation on Azure, Copilot Studio and Power Platform.

Before Microsoft, I spent about two years close to how AI models are trained. At Scale AI I grew the Finnish localization program from 5 to 100 active users in seven months. At Mercor and Outlier I reviewed AI-generated code and wrote coding tasks used to train and improve AI models.

Alongside work, I'm doing a Master's in Computer Science at the University of Jyväskylä, with a focus on software engineering and distributed systems.

Projects

  • AI Idea Prioritisation Platform review step: duplicate warning, AI assessment with value and feasibility scores, and the value calculation

    Personal project · 2026

    AI Idea Prioritisation Platform

    Turns business ideas written in plain language into ranked proposals that a review board can act on. A Claude agent extracts the facts, flags duplicates, estimates annual value with deterministic code and scores each idea by priority.

    • Built a tool-using agent on the Claude API with strict, Zod-validated tools: pgvector semantic search for duplicates, a deterministic value calculator and a typed assessment streamed live to the browser.
    • Applied production LLM practices: prompt-injection guardrails, prompt caching, per-call cost and latency telemetry, and golden-case evals.
    • Covered by 34 unit and integration tests plus Playwright end-to-end tests, run in GitHub Actions against Postgres with pgvector.

    Founder & Lead Developer · 2025

    Workflow Automation Platform

    Multi-tenant SaaS platform with a visual node-based workflow designer, built with Spring Boot 3.2 and React 18.
