OPENING QUESTION

"SIAPA YANG NGODING
TANPA AI SAMA SEKALI?"

5 years ago, the opposite question made sense. Today, not using AI is the weird thing.

BUT, LET'S BE HONEST

DON'T RUSH TO
BLAME AI

Yale Budget Lab (Oct 2025): 33 months after ChatGPT, AI's effect on jobs is "near zero — statistically indistinguishable from zero." NY Fed & Goldman haven't found a clear AI footprint either.

AI JUST ADDS SPEED — IT'S NOT THE ROOT CAUSE.
BUT FOR US WHO CODE, THE ENDING IS THE SAME:
THERE'S A CHEAPER OPTION NOW.

I joined as a Flutter Engineer to rebuild app v2.0 from scratch to launch. What got me promoted wasn't the code — it was owning the data, ideation, user research, and roadmap.

READ DATA

RESEARCH THE DATA
WITH AI

Problem: wanted to know which Premium FYP slot lands — single card vs carousel.

MY PROMPT → CLAUDE CODE

help me set up a Mixpanel dashboard for this A/B test

TAKEAWAY

AI scanned the codebase & found the event tracking itself. I decide which metrics matter & what the conclusion is.

RESEARCH USERS

RECAP INTERVIEWS
WITH AI

PROBLEM

After a user interview, notes are scattered & long — it's easy to skip the key insight.

MY PROMPT → GEMINI

recap this user interview, and advise the next step

TAKEAWAY

AI filters & summarizes. I decide which insight becomes a feature.

WRITE DOCS

RAW NOTES →
PRODUCT BRIEF

PROBLEM

My research is still raw & messy — hard for product/design to read, especially non-technical folks.

MY PROMPT → GEMINI

rewrite this research doc into a delivery-ready doc for the product team — best practice

TAKEAWAY

AI polishes the writing. I own the content & decisions — communication = a product engineer's core job.

VENDOR ANALYSIS
+ WRITE PRD

Problem: building a TTS feature (Lyre) — many vendors, must pick the best fit on quality & cost.

MY PROMPT → CLAUDE

you're a product expert — create a PRD for TTS, Tech in Asia Lyre

TAKEAWAY

AI gathers options (WaveNet · ElevenLabs · Kokoro) & weighs trade-offs. I make the final call & own it.

DESIGN UI

DIRECTIONS WITH AI

Problem: a section feels flat & generic — I want a premium redesign direction fast, before involving design.

MY PROMPT → CHATGPT

redesign this "Companies" section — premium fintech / VC aesthetic

TAKEAWAY

AI generates visual directions in seconds. I judge what fits the brand & user — then steer it to ship.

PLAN FIRST →
AI SHIPS THE CODE

Problem: add horizontal scroll for premium content in the FYP home — needs a real plan, not vibes.

MY PROMPT → CLAUDE CODE

you're a product & ux expert. /plan this feature — handle the best practice

TAKEAWAY

AI explores the codebase, plans, then builds it (cooked in 13m). I steer the UX & product decisions.

FLUTTER'S ROLE

FLUTTER =
LEVERAGE FOR
PRODUCT ENGINEERS

AI speeds up coding + 1 codebase multi-platform = the loop prototype → test on users → improve gets really short.

SO WHAT?

3 CONCRETE
THINGS TO
START
TOMORROW

01
DON'T JUST GENERATE — LEARN TO JUDGE THE CODE

84% of devs use AI, but only 3% "highly trust" the output. The expensive skill = knowing what's wrong/nonsense/unsafe. Don't skip the fundamentals.

02
RAISE YOUR ALTITUDE

For every feature ask: "for whom? what problem? how do we measure success?" — the muscle used in the loop above. Industry demand is shifting toward more experienced, AI-capable profiles.

03
USE AI TO GET SMART FASTER — NOT TO STOP THINKING

For every AI answer, ask "why?" until you get it — it's the industry's #1 move too: orgs are 3.5× more likely to upskill than hire (Linux Foundation 2026). Level up your skill, don't outsource your brain.

17 / 19

The old question: "if AI can code, what am I for?" → The right question:

"IF AI ALREADY HELPS WITH CODING, WHAT DO I WANT TO BUILD?"

CODE TO BUILD
THINGS PEOPLE USE.

FLUTTER = THE TOOL
AI = THE ACCELERATOR
MINDSET = THE DECIDER

What makes you valuable in the AI age isn't how fast you type — it's how deeply you understand the problem. For product thinkers, this is the best moment to jump in.
