People always ask me, “Rona, why did you take your MBA?” 

And every start of a new semester, a professor asks the same question - which means I have to stand up, introduce myself again, and explain myself in front of my classmates like it’s a courtroom hearing.

The truth is...

I never really planned on taking an MBA.
If you asked 18-year-old me, or even 21-year-old me fresh from Japan, I probably would’ve said something like, “No thanks, I’m tired.”

But life has a funny way of steering you toward things you didn’t think you needed -- until you’re suddenly in the middle of it, eating accounting sheets (i hate accounting) and case studies (there's just too much) for dinner and midnight snack.

So yes, at this point, I’ve memorized my answer.
Here’s the full version - both the serious one and the slightly chaotic on (my personality, really).

1. Because - initially - I was bored

Let’s start with the honest (and funny) reason - which, according to my METRES prof, is valid. :>
I took my MBA partly because life felt too routine, too predictable, too “wake up, work, sleep, repeat.”

Basically, “because I was bored.” 

So, I complicated my life by enrolling in grad school. (Peak decision making lol)
Healthy coping mechanism? Debatable.
Effective? Absolutely.

Of course, that’s the version I say jokingly during introductions.
But there are deeper reasons too.

2. Because I wanted to understand the business behind the tech

I’ve spent my entire career inside the tech world: engineering, SAP, AI, Japanese systems, and all the glorious chaos that comes with them.

But somewhere along the way, I realized something important:
It’s one thing to build technology.
It’s another thing to understand why companies need it, how they pay for it, and what value it creates.

Suddenly, I didn’t just want to know how a system works.
I wanted to know why companies decide to build it, invest in it, or scrap it entirely.

MBA felt like the missing puzzle piece.

3. Because I’m leading teams now - and leadership needs more than technical skills

When I started handling people, clients, and entire delivery lines, I officially learned that technical skills aren't enough.
I realized leadership is not just “being good at your job.”

It’s:
  • understanding how businesses move
  • managing people with different personalities
  • making decisions backed by data, not vibes
  • communicating clearly
  • balancing budgets (stressful, would not recommend)
  • and having the confidence to speak for your team

MBA became the safe space where I could learn all these without risking a multimillion-yen project.

4. Because I wanted to grow outside my comfort zone

Most of my life has been all about tech, and I wanted to expand my world - I wanted to learn from people who think differently.

And MBA gave me that.
It stretched my thinking and challenged the way I solve problems.

Studying with people from different backgrounds - finance, marketing, HR, operations, med, creatives - helps me see things from angles I’d never encounter in my day-to-day work.

MBA feels like a reset button.
A chance to step back and think bigger.

Uncomfortable? Yes.
Worth it? Also yes.

5. Because future Rona will thank present Rona

I know myself.
I would never regret learning more, but I would regret not taking opportunities when I had the chance.

Whether I stay in tech forever, shift to strategy, move deeper into leadership, or end up building something of my own - this MBA will support that version of me.

And honestly?
Right now, I’m trusting the version of me who said “Why not?” and sent in that MBA application.

So, yeah, taking my MBA wasn’t really part of the plan.
But I’m glad I’m here - learning, growing, tired, caffeinated (with matcha only lol), and building the next chapter of my life.

Here’s to the journey. 🦅💙


Hello, it’s Rona - glad to see you here. 🌸 

Let me tell you how I ended up in Tech. 
Spoiler: it’s not as dramatic as you think, but it is very me. 

The Very Early Beginning 

Back in high school, I was under a contract with Philippine Science High School that basically told me, “Pick a course in science, math, or technology.” 
So I did the math (pun intended) and enrolled in BS Electronics and Communications Engineering at UP Diliman. 

Not exactly a passion-led choice -- more like contractually obligated, but it worked out surprisingly well. 

How Japan Entered the Chat 

One random career fair in UP changed everything. 
A Japanese company called Anritsu visited, conducted an exam and interview for around 300+ students, and somehow I became one of only seven people who passed. 

Thanks to that accident (a story for another day haha), I got hired even before graduating in June 2018. 

By October 2018, armed with basic Japanese, three suitcases (two medium-sized, one hand carry), and naive optimism, I flew to Japan, lived alone in a company dorm, and officially entered the tech world. 

My First Real Job (and the Hardest One for My Brain)

My first role was as a Research and Development Engineer at Anritsu in Kanagawa, Japan.
This is the job that used my brain cells the MOST. Like… ever.

I designed metal detection systems for food and pharma industries, tweaked frequencies, worked on image processing, and handled end-to-end hardware and software development.
It was exhausting (an understatement) but incredibly fulfilling (also, an understatement).

It also forced me to speak better Japanese, because apparently you need language skills to argue with senior engineers about electromagnetic waves. lol

During my three years there, I automated as many processes as I could and eventually received four company awards:
  • 3 Quality UP Awards
  • 1 High Performance Award

Not bad for a girl who still couldn’t eat natto.

Pandemic Arc: The Homesick Era

Then the pandemic happened.
I got homesick (for a small reason, but with big emotions), packed my things, and went back home.

I accepted the first job that hired me -- not the most strategic choice, but honestly one of the decisions I’m most grateful for.
Because that’s where my actual Tech career in the Philippines began.

My Tech Journey (a.k.a. The SAP Era)

Accenture

My first tech job in the Philippines was at Accenture, under the Order-to-Cash (OTC) process for the SAP Sales and Distribution (SD) module.
This is where my SAP story started.

And because I hate manual work, I ended up automating accounting processes “for fun,” which got me a recognition award.
Then I left one year later, as one does.

Fujitsu (Philippines and Japan)

After Accenture, I spent two years at Fujitsu as a Bilingual SAP Consultant / Bridge System Engineer (BSE).

I handled their biggest SAP account, worked across PH and Japan, and collected two more awards before moving on.

IBM Chapter: The Now Era

Currently, I’m with IBM as the Department Head for SAP Technologies and Applications and Operations Service Line Lead for the Japan Client Service Unit (JCSU).

My work involves:
  • Building and strengthening SAP capability in the center
  • Bridging Japanese clients with our PH delivery teams
  • Hosting and collaborating with Japanese companies
  • Winning projects for the center (my favorite part, i guess)
  • Occassional singer for visiting clients from Japan (don't ask)

On the side, I champion AI adoption in the SAP field.
In just one year since starting (Nov 4, 2024), my SAP AI teams have:
  • Built 2 original SAP AI assets
  • Localized 5 SAP AI assets into Japanese

AI girl era unlocked.

Looking Back

Sometimes I amaze myself knowing everything connected so neatly:
  • My Japanese background led me to Accenture
  • My SAP foundation led me to Fujitsu
  • My SAP + project management experience led me to IBM

If the order had been different, would I still end up here?
Maybe. Maybe not.

But so far, seven years in tech have been unexpectedly great.
Looking forward to year eight. 💙

Hello, everyone! 

Thanks for stopping by my little corner of the internet. 

This website started as RONALAINE’S DIARY way back in September 13, 2018 — a personal journal where I poured out my thoughts, shared the poems I wrote, posted my go-to recipes (because living alone meant cooking for myself), and told late-night stories from when I first moved to Japan fresh out of college. (I've archived most of the entries, btw)

Over time, it evolved into a travel blog full of my favorite itineraries, and later, a space for sharing Japanese tips and lessons I’ve picked up along the way. 

Tbh, it’s been a while since I last updated this site (except that one random post in October 14, lol). But here I am again — partly because my postgrad professor asked us to make a website, and thought, why not recycle this one? 

So right now, it’s temporarily rebranded as RONALAINE’S WEBSITE to sound more professional. (Let’s pretend it does.) 

Anyway, thanks for visiting! I hope you find something here that makes you smile, think, or at least stay a bit longer than you planned. :) 

- Rona
