About

I'm a senior full-stack engineer at Tixio, where I've spent four years building the Tixio app and its sister products.

I like the hard parts: realtime systems, data migrations on live products, performance, and the decisions that shape a codebase.

I work across React, NestJS, PostgreSQL and MongoDB, and lately also Go and C++.

Products I worked on

Tixio app Tixio's main product. A workspace app with chat, tasks, a wiki, boards, HR and CRM, on web, desktop and mobile.

Sep 2022 - Present

Major contributor. The product I've worked on the most, across the frontend and the backend.

  • Chat unread tracking. Redesigned how chat counts unread messages, replacing per-row counters with each member's read position. Tested the design on a simulation of 1 million messages, where it cut the documents scanned per sent message from 515 to 8, and rolled it out with four migrations of live data.
  • Message pipeline. Wrote the chat backend's message pipeline: a single writer for every message, read state, thread follows and fan-out. A CI check blocks any other code from inserting messages.
  • Chat feed. Rebuilt the message feed and thread panel on TanStack Virtual, so long conversations scroll smoothly.
  • Wiki. Rebuilt the collaborative wiki on Tiptap by myself, and moved existing documents from the old editor without rewriting the stored data.
  • Shared editor. Built the rich-text editor library that 8 parts of the product use, including chat, tasks, CRM and the wiki.
  • HR. Top contributor to the HR module: leave, contracts, holidays, and employee surveys with eNPS.
  • Master Ledger. Built CSV import and merge that runs off the main thread and reports which rows it added, updated and skipped.
  • Mobile. Brought chat in the React Native app for iOS and Android up to the web app's behavior, from unread dividers and threads to notifications, and shipped the staging releases.
  • Widget board and tasks. Worked on the widget board and the second version of the task module, with list, board, calendar and roadmap views.
  • Platform. Laid the groundwork for moving all apps into one monorepo, built a verifier for the backend data migration, and fixed 997 failing end-to-end tests.

Vadio A video meeting and CRM platform for service businesses, built by Tixio. It has browser and mobile meetings with AI summaries, guided customer videos, orders, invoicing and a public API.

Aug 2026 - Present

Feature lead. I led five features from spec to release, across the web app and the backend.

  • Record and send. Built a new product from scratch. Customers record one guided video on their phone, uploads resume after a dropped connection, and the server converts the video in background jobs. It shipped with 152 automated tests and 0 flaky ones.
  • Direct join. Trusted members skip the pre-join screen and the meeting connects before their camera is ready. Camera and mic problems get browser-specific help for 6 browsers in 6 languages.
  • Mobile sign-in. Built native Google sign-in for the iOS and Android app, with connected accounts and password screens, and added Record and send to mobile.
  • Memory leaks. Found and patched two bugs in the LiveKit client library that kept a meeting room in memory after users left. After 5 rejoins, leftover objects dropped from 20 to 0.
  • Faster start. Cut dashboard ready time from 1,070 to 560 ms and removed all layout shift on load.
  • Security. Closed a race condition in company signup, made secret checks timing-safe, and blocked API tokens from video playback.
  • Also led. Social sign-in with Google, Apple and Microsoft, the public developer API, AI-assisted invoice upload, and Finnish, German, Swedish and Danish translations (46,000+ strings).

Animal-welfare certification platform A certification platform for sports clubs. Clubs go through onboarding, training, a self-assessment, an improvement plan and an expert review, then renew every year.

Jun 2026 - Nov 2026

Lead engineer. I joined after the initial setup, designed the architecture and built most of the product.

  • Lead engineer. Designed the architecture, wrote about 73% of the code, and reviewed the rest of the team's work.
  • Deadlock. Fixed a database deadlock that could lock a club out for good. Test runs went from 2 of 5 stuck to 10 of 10 clean.
  • Certification gate. Closed a gap where API callers could get certified with required work still open.
  • Migrations. Replaced 26 database migrations with one baseline, verified identical across 513 columns and 490 constraints.
  • CI. CI was killing the end-to-end test job at its 10-minute limit. Split it into four parallel runs of about 30 seconds each, and grew the suite to about 2,100 tests.

Tourism and destination platform A platform for regional tourism websites. Editors manage places, events and news in a CMS, and visitors get a multilingual site with maps, calendars and search.

May 2024 - Oct 2025

Frontend-focused full-stack engineer. I built most of the public website and many CMS features, plus backend changes where the UI needed them.

  • Public website. Built the place, event, news and content pages on the Next.js App Router, including galleries and responsive layouts.
  • Interactive map. Built a Leaflet map with clustering, GPX routes and a mobile bottom sheet. Added a backend filter so the map only loads places in view.
  • Search and calendar. Added filters that live in the URL so searches can be shared, with result counts from the server and infinite scroll, plus an event calendar.
  • Languages and SEO. Set up three languages with localized routes, and handled metadata, sitemaps and server rendering for SEO.
  • CMS. Added recurring events, previews, version history with restore, image uploads, map pin placement and an optional AI rewrite step.

  • Built the live sandbox for testing the shopping assistant, and added product search with MongoDB Atlas Search.
  • Prototyped the conversation engine and the storefront.
