KidzLog is Officially Live! 🎉
Numerous bugs squashed.
Tons of feedback.
Just getting started

[Peter Oliha @PeterOliha]

AI hasn't replaced me. It replaced hours spent debugging, searching, and writing boilerplate.

Less Googling syntax. More time on architecture and edge cases.

Notepad → IDE → Stack Overflow → AI. Just the next step.

[Peter Oliha @PeterOliha]

First line of code: 20 years ago.

90% of what I know came from my own projects. Not courses. Not the day job.

School taught syntax. Work taught process. Projects taught judgement.

You learn different when there's no tech lead to bail you out.

[Peter Oliha @PeterOliha]

I'm a big believer in using your own product.

This weekend I'm migrating MapleStack to pull jobs directly from https://t.co/o3ek7X6UYO's API.

Real usage exposes gaps fast and improves the data.

Infrastructure that can't handle its own creator won't handle anyone else.

[Peter Oliha @PeterOliha]

Every job API I tested: stale listings, duplicates, recycled data.

Built my own pipeline for MapleStack — direct to employer career pages. A year of refining it taught me others need this too.

That's Jobven. Still early — 20k listings, growing weekly.

[Peter Oliha @PeterOliha]

Jobven API reference is live.

[Peter Oliha @PeterOliha]

From Canadian companies to global coverage.

Built MapleStack to collect job data directly from employer career pages. Now scaling globally with Jobven.

Early days — 20k listings, adding more weekly.

[Peter Oliha @PeterOliha]

I deleted 10,000 listings from https://t.co/0gxze7VhQj.

Scraped data looked impressive but was worthless. Started over with organic, verified providers.

100+ engaged businesses > 10,000 stale listings.

Quality > vanity metrics.

[Peter Oliha @PeterOliha]

"There's no time like the present."

Perfect conditions don't exist. We keep saying no to ourselves.

I waited to build MapleStack. Started anyway. Now it's live, thousands of jobs indexed.

Pick one thing. Start today.

[Peter Oliha @PeterOliha]

It's November. Remember those New Year's resolutions?

Pick ONE thing and make progress before Dec 31st.

Ship that project. Write that post. Launch that feature.

One win > zero wins.

What's your one thing?

[Peter Oliha @PeterOliha]

Unexpected benefit of AI coding: it makes you better at code reviews.

AI code forces you to actually read it - can't assume it's correct. You catch logic errors, duplicate code, non-existent functions.

That skepticism transfers to all code reviews.

POV: You just had another "genius" idea at 2am 💸

Domain purchased ✅
Project built ❌

How many domains are you sitting on? 😅

[Peter Oliha @PeterOliha]

Canada is 10th in GitHub developer communities 🇨🇦

40M people vs the big players - smallest in top 10?

Punching above our weight, but we can do better:
• More open source
• Accessible tech education
• Keep talent home
• Stronger startup ecosystem

Small but mighty 💪

[Peter Oliha @PeterOliha]

"I need a developer" messages have dried up.

Why? AI assistants, no-code tools, automation platforms - the technical barrier is gone.

Anyone can build MVPs, landing pages, automations now.

The freedom to build isn't just for devs anymore.

[Peter Oliha @PeterOliha]

Everyone has ideas. Execution is the difference.

3 things that helped me ship:
• Start with the smallest version
• 30 min daily, even when you don't feel like it
• Write down what you learned from failures

Ideas fade. Habits compound.
