I’m Vijay, an engineering manager and hands-on architect in Toronto. 17+ years in software, from BlackBerry Messenger to fintech, health and IoT platforms.

I lead the Workflows and Portal squads at OneVest, build small products under Renu Design, and teach Python to young builders. I write here occasionally as Wildcard.

Things I've built under Renu Design.

Kanakku

The money book for your group.

Home inventory with photos, locations, categories and tags, and search across everything.

Kanban for your terminal.

Your todos as a markdown file in a git repo you control. A keyboard-driven board that commits every change. No database.
