The Challenge: When Smart Systems Aren’t Smart Enough
There’s something darkly comedic about building a “smart” scheduling system, only to realize it’s a little too smart — like your GPS refusing to take shortcuts because they “aren’t optimal.” That was me. I’d poured countless hours into a sophisticated relief assignment logic engine that, on paper, should have been flawless.
But here’s the catch: it was programmed to look for overstaffed shifts — and in my beautifully optimized system, overstaffed shifts were as rare as Bigfoot on a Segway. The logic was technically correct… and completely useless. Relief assignments were firing maybe 5% of the time. That’s not smart — that’s sarcastic.
The Breakthrough Moment: Reality Check, Table for One
One night, running on instant noodles and too much coffee, it clicked: what if I was looking for the wrong problem?
Instead of chasing overstaffed shifts (unicorns), I pivoted the logic to find underutilized opportunities — shifts with capacity for more coverage. In other words, instead of plugging a flood, I started watering the garden.
And it worked. Suddenly, relief assignments were happening in 85% of cases, flowing like clockwork. Managers got the support they needed, employees got fair coverage, and I finally got to delete a bunch of “reliefFailed” error logs with a smug smile.
The Ghost of “No Scheduled Employees”
Just when I thought I’d cracked it all… the frontend gaslit me.
Despite the backend sending pristine, perfectly structured schedules, the frontend returned a blank slate: “No scheduled employees” — like it was ghosting the backend entirely.
So, I dove into the frontend code like a crime scene investigator. The issue? The backend was delivering data in a format the frontend didn’t understand — basically sending Shakespeare to someone expecting emojis.
To fix it, I built dual data structures — one for internal processing, and one custom-tailored for the frontend. Think of it like writing in two languages simultaneously: one for machines, one for humans. Boom. Frontend suddenly remembered its coworkers again.
The PDF Revolution: Goodbye, Generic Legends
I couldn’t ignore the PDFs either. What started as “good enough” was now actively sabotaging the user experience:
- Legends were hardcoded, out of date, and often confusing.
- Long Malay names broke the layout, spilling over like uninvited guests at a wedding.
So I built a smarter system.
- Legends are now dynamically generated from the actual shifts in the database — always current, always accurate.
- I also crafted an intelligent name formatter that trims long names without disrespecting identity. Because “Nur Aisyah binti Mohd Faizal” should never be reduced to “N.A.b.M.Fa” unless it makes sense.
Now, the PDFs are clean, professional, and respectful of the people behind the data. They’re actually usable — and even a little pretty, if I may say so.
The Impact: From “Oops” to “Oh Yeah”
Let’s break it down:
| Before | After |
|---|---|
| Relief assignments happened ~5% of the time | 85% of shifts now utilize relief effectively |
| Frontend couldn’t display scheduled employees | Fully synced, readable schedule views |
| PDFs looked like a design disaster | Smart, respectful, and branded output |
| Static code and mismatched structures | Dynamic, adaptable, and future-proof |
Lessons I Learned (and You Can Steal)
💡 Challenge Your Defaults
Just because the system is “working” doesn’t mean it’s working well. I stopped chasing rare cases and optimized for the real world.
🌏 Culture Matters in Code
Malay names, international phone numbers, even time zones — if your app ignores cultural context, it’s not built for humans. Fix that.
⚙️ Your Frontend Isn’t Psychic
Send the right data, in the right format. Don’t assume it knows what the backend meant. Communicate like you’re explaining it to a sleepy intern.
🚀 Dynamic > Static, Always
Dynamic logic adapts to real-time data. It scales, it updates itself, and it reduces maintenance. It’s not a luxury — it’s essential.
Conclusion: Scheduling is a Science (With a Bit of Sass)
What started as a quirky little logic oversight ended up rewriting how my system handles relief shifts, schedules, and PDF generation. It wasn’t just a fix — it was a transformation.
The system now balances teams efficiently, presents clean reports, and just works — with no yelling at the screen involved. All it took was a change in perspective, a few sleepless nights, and a lot of trial and error. But that’s what building great tech is all about.
