Lauri Tuumi

Technical Lead

Lue suomeksi

I'm a full stack tech lead. I own the full lifecycle of implementations — from architecture and API design to scalable deployment and ongoing development.

I focus on keeping teams productive without over-engineering: establishing shared conventions, creating clear and adaptable patterns, and making deliberate calls about when to add structure and when to stay simple.

I'm interested in developer ergonomics, principled architecture, and truly scalable AI-assisted development.

Static Next.js Export

This project is exported as a fully static site. Deploying to Github Pages or Cloudflare Pages means no backend or database to manage and secure.

For a CV, it's the obvious choice: fast, simple. The complexity matches the problem.

PDF Export

The site generates a PDF on every deploy, so there's no separate file to maintain. When applying, I grab the latest from the site — no version drift, no stale attachments.

The exported PDF is ATS-friendly. Human readers are encouraged to view the full stylized version online.

Contact UX

I don't use a desktop email client, so a bare mailto: link would just mean hunting for the address to copy-paste it. I let the user choose how to handle the email — less friction, more results.

Small interactions like this reflect a broader interest in UX: the best interface is one you barely notice.
