From the first commit to the live domain in about two days, with 108 indexable pages.
Business context
What the client needed
Accounting and legal support for Ukrainian sole proprietors and companies: a deadline calendar you can subscribe to, three tax calculators and 19 service pages in three languages.
The firm had a theme-based site that search engines could not place. The goal: an entrepreneur finds the site through a deadline or an amount, gets an exact answer from a tool, subscribes to the deadline calendar, comes back every quarter - and asks for help when the task gets harder.
User stories
What people do with it
- As a sole proprietor, I want my tax deadlines and amounts in my phone's calendar, so that I never pay a fine for a missed date.
- As an entrepreneur, I want to see which tax group is cheaper for me, so that I choose before I file.
- As the firm, we want every request saved before it is sent, so that no client is lost to a failed email.

Key challenges
What made it hard
- 01Numbers you cannot get wrong. No rate is hard-coded; editing one unpublishes it until it is confirmed again, and without confirmed rates the calculators hide instead of showing an empty answer.
- 02Deadlines are legal rules, not dates. "By the 20th" and "within 40 days after the quarter" give different days, and weekends move reports later but payments earlier.
- 03Moving a domain with search history. Indexing opened at the switch and the old URLs got permanent redirects, so rankings carried over.

A game about fines
Thirty seconds: deadlines fall, and each miss costs the real fine from the Tax Code. It loads only on click.
