Nine systems. Full receipts.
Case studies are reserved for AI, infra, search and operating systems. Plain website work stays in the portfolio wall; every card here has a concise description and a dedicated full-story page.

01
ProfiElekter OÜ
Seventeen years of real projects (Swissotel, Hilton, a 50,000 m2 industrial LED refit) sat invisible on a 13-year-old Weebly site. We migrated it like-for-like first, losing zero ranking pages, then grew it into a 125-page multilingual search system. The useful proof is the technical SEO layer, structured documentation, and audit trail.

diil.ai
A multi-tenant proptech platform where every property developer runs listings, leads and investor reporting on their own subdomain. Traditional agencies quoted $80-150K and 4-6 months. We built it as six modules on our own stack. It now runs $100M+ in transactions across 50+ agencies.

The kratt lead engine
Manual prospecting capped our own pipeline at 20-30 conversations a month. So we built an engine that finds businesses, scores their websites with AI, and generates a personalized landing page per prospect. It feeds our own outreach for about $0.50 a lead.

diil.ai SEO engine
A Python engine pulls keyword clusters, writes long-form posts in diil.ai's brand voice, and publishes to a Supabase-backed blog on a cron. It ships 100+ posts a month with zero human hours. The output is public, read it live.

The content machines
A four-loop pipeline that turns a codified brand DNA file into finished ads, carousels and campaign frames. It fingerprints every combination it fires and refuses to repeat one inside 30 days. 66 machine-rendered creatives across 6 brands so far.

CMS + Deploy Loop
Leather craft · Estonia
06
Nahkur
A one-man leather workshop got a static site with an editor-to-production system underneath it. Catalogue data, Valencia product data, portfolio cards and hourly-rate copy became editable without turning every change into a developer ticket. The receipt is the CMS render loop, bilingual data model and deploy path.

Infra + Automation
Kratt operations · internal
07
The automation spine
Kratt runs a shared n8n automation instance instead of scattering one-off scripts across laptops. It sits behind a public webhook front door and a private admin path, with Postgres state, execution pruning and runbook limits. The public story is architecture and operating discipline, with secrets and endpoint details deliberately withheld.
Data + Lead Ops
Estonian open data · internal
08
Registry radar
A daily Ariregister diff watches Estonian company data for new registrations, new VAT numbers and liquidation signals. A second list-hygiene job reconciles the live call list against that snapshot so sales knows who to call and who not to touch. It runs read-only until a human decides the signal quality is worth writing into CRM.

Backup and restore test
The backup loop dumps the operational stores that would hurt if the box died, then verifies row counts instead of trusting file existence. A separate weekly restore test loads those dumps into a throwaway Postgres and destroys it after proving the data loads. It is continuity work with failure alerts, retention rules and known gaps stated plainly.
