About Me

I'm Peter Oliha, a software engineer based in Ottawa, Canada. I've been writing code for 20 years—15 of those professionally. By day, I build backend systems and APIs. On the side, I'm building a portfolio of products: Jobven, MapleStack, FindChildcare, and KidzLog. Most of what I know came from shipping my own projects. I write about the lessons along the way.

Built for developers creating job boards, recruiting tools, and market intelligence platforms.
MapleStack

MapleStack

MapleStack is a Canadian job board built to make job searching simpler, smarter, and a lot less overwhelming. It aggregates job postings directly from company websites across Canada and organizes them in one easy-to-browse platform.
KidzLog

KidzLog

KidzLog provides a full suite of tools to help you manage various aspects of your childcare business. From tracking attendance to handling billing and payments, the goal is to meet the needs of childcare providers, whether you run a home-based daycare or a larger childcare center.

Where should I validate? Everywhere, and for different reasons

Validation is one of those topics that feels boring until something goes wrong in production. Here is how I think about validation across the stack, with real examples from the apps I run.
