## Projects

### [AI Idea Prioritisation Platform](https://teemuiljin.com/projects/ai-idea-prioritisation) (Personal project, 2026)
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.
- Tech: Claude API, Next.js 15, TypeScript, PostgreSQL + pgvector, Zod, Vitest, Playwright, Docker

### [Workflow Automation Platform](https://teemuiljin.com/projects/workflow-automation) (Founder & Lead Developer, 2025)
Multi-tenant SaaS platform with a visual node-based workflow designer, built with Spring Boot 3.2 and React 18.
- Secured stateless APIs with JWT authentication, rate limiting, and automated OWASP dependency scanning.
- Built conditional logic, WebSocket notifications, email/SMS delivery, and REST integrations for Slack and Google Workspace.
- Shipped with Docker, Kubernetes, and GitHub Actions.
- Tech: Spring Boot, React, JWT, Docker, Kubernetes, GitHub Actions, WebSockets
