I build products
and I keep them alive.

I’m Igor Varyvoda, a product builder and operator behind Sirv Studio and a living portfolio of independent software.

Some for work, some because I can’t help myself.

Made in Ukraine. Based in Montenegro.

Some became businesses. Some stayed small and useful. I still look after them.

  1. 2026 · Evolving vibeq

    VibeQ started as a task board for Sirv Studio. Now it runs the queue behind Sirvant, the Slack bot my team uses to investigate and ship work.

  2. 2021 · Long running Earth Roulette

    Press the button and Earth Roulette picks a destination. Filters and travel data help decide whether you should actually go.

  3. 2025 · Evolving BudJet

    I use BudJet every day. It scans receipts, keeps the line items, and shows where the money went without making me type every purchase.
