From Spending 30 Minutes on Every Email to Just One: How Gemini Changed My Workdays as an Engineer and Dad

Hi, I'm LinkHubJin — an engineer in Singapore, and more importantly, dad to two very energetic daughters. A few readers have asked me some version of the same question lately: how do I manage work, family, and still find time to learn new things? I don't really have a system for it. I just stopped wasting time on one specific task that never deserved as much of it as I gave it: writing English emails.

If you've worked with overseas clients or consultants, you probably know the feeling. The actual engineering is usually the easy part. Finding the right words, making an email sound professional, reading it three times before hitting send — that's what eats the hours. Things changed for me once Gemini became part of my daily routine. It didn't make me a better engineer. What it gave me was time.

The Real Problem Was Never My English

International projects mean the emails never really stop. Consultant questions, drawing revisions, site issues, approvals, supplier coordination — it's already piling up before I've finished my first coffee some mornings.

Then I'd get home, wanting nothing more than to see my daughters, and end up back on my laptop rewriting the same email for the third time because I wanted it to sound just right. Looking back, my English wasn't actually the issue. I was burning energy trying to make every sentence perfect, and that habit was quietly eating my evenings.

The Simple Prompt I Use Every Day

At some point I stopped trying to write "proper" English from scratch. Now I write my thoughts out in Korean first, get the technical details straight in my head, then hand it to Gemini to turn into a business email.
The prompt is nothing special:
"I'm a senior engineer working in Singapore. Please rewrite the following notes into a professional business email. Keep the tone polite, natural, and easy for the recipient to understand."
That's it. The engineering, the decisions, the actual content — all still mine. Gemini just helps it come out clearer.

From Rough Notes to a Professional Email

I remember needing to explain a piping issue to another team a while back. Normally that's ten, fifteen minutes of fiddling with wording before I'd hit Send. This time I just pasted my notes in. A few seconds later I had a clean email — subject line, structure, the whole thing — and the technical content hadn't changed one bit. Only how it read.

I still catch myself rereading emails I've written, wondering if a line sounds too blunt or too vague. These days I spend that extra time on drawings instead. My emails somehow read better now, even though I spend less time on them.

The Best Thing AI Gave Me Wasn't Productivity

I thought at first the whole point was writing better emails faster. It took a while to realize the real benefit had nothing to do with writing at all — it was getting my evenings back.

Instead of sitting at the laptop after dinner, I close it earlier now. Take the girls outside. Play. Have an actual conversation with my wife instead of half-listening while typing. Technology should make life easier, not busier — for me, Gemini hasn't replaced my work, it's just taken one repetitive task off my plate so I have more room for the things that actually matter.

Whenever people ask why I use AI daily, I don't usually start with productivity. I talk about time. Every minute I don't spend fixing a sentence is a minute I get to spend with my family — and that's really the only metric that matters to me.

The Honest Breakdown of My Monthly Cost of Living in Singapore as a Family of Four (2026 Reality)

Image
When people consider a job offer in Singapore, they tend to focus on the gross salary and the low tax rates, exactly the numbers I broke down in my post about filing income tax here as a foreigner . Those numbers look genuinely great on paper. But running an actual four-person household here, with a spouse and two young kids, turns that clean spreadsheet math into something a lot messier month to month. I keep a rough running tally in a notebook, mostly out of habit from work, and pulling it out last quarter to actually add everything up was a bit of a reality check even for me. The real cost of living here has climbed noticeably over the past few years, mostly driven by housing and the fact that foreigners get none of the local subsidies built into daily life. Here's an honest, itemized look at what our monthly household expenses actually looked like last quarter. The Three Costs That Set Everything Else For any expat family, three fixed costs basically dictate how much breathing...

What Nobody Tells You About Preschool Hunting in Singapore

Moving to Singapore felt manageable, honestly, right up until we had to figure out where our daughter was actually going to spend her days while we worked. The city itself is easy to navigate. Preschool enrollment, on the other hand, turned into the one part of settling in that genuinely stressed me out, more than the visa paperwork ever did. Nobody warns you about this part before you move. You hear about visas, housing, the tax situation. Almost nobody mentions that finding a decent childcare spot near your neighborhood can take weeks of phone calls, waitlists, and awkward compromises between what's convenient and what's actually available. We found that out the hard way, a few weeks into settling in, when a center we'd assumed would have space turned out to have a waitlist stretching well past the school year we needed. What Preschool Actually Looks Like Here Before you even get to primary school, there's a whole early childhood system to figure out first, and it...

What I Learned After Filing My Income Tax in Singapore as a Foreign Professional (2026 Experience)

Image
Working in Singapore as an Employment Pass holder gets sold as a financial win before you even arrive — low tax rates, world-class infrastructure, the whole pitch. And honestly, a lot of that pitch is true. But after going through another tax filing season here, I've come to see the math a little differently than I did when I first moved. I remember sitting with the IRAS portal open my first year, genuinely pleased with how low the numbers looked, before I understood what wasn't being subtracted from anywhere. The headline tax rates really do look friendly at first glance. What nobody mentions upfront is that Singaporean citizens and permanent residents get access to a wide range of deductions and rebates that non-citizens simply don't qualify for. You end up paying something closer to the raw, unfiltered rate while managing a household budget that has none of the local subsidies built in. It's a very different experience once you're actually filing than the recrui...
