The real secret to becoming a data professional isn't technical skills—it's storytelling.

Here's how narrative trumps numbers.

When I first entered the world of data, I was captivated by the endless possibilities that numbers could unlock.

But soon, I realised something crucial: data alone doesn't speak.

It's the story you weave around it that truly makes an impact.

Let me explain how you can harness the power of storytelling in data:

1. Understand Your Audience
  ↳ Tailor your narrative to resonate with the specific needs and interests of your audience.
  Whether you're speaking to executives or data enthusiasts, adjust your story accordingly.

2. Find the Human Element
  ↳ Data is ultimately about people.
  By highlighting the human impact, you make your insights relatable and actionable.

3. Create a Compelling Narrative Arc
  ↳ Like any good story, your data-driven narrative should have a clear beginning, middle, and end.
  Start with the problem, introduce the data, and conclude with actionable insights.

4. Simplify Complex Data
  ↳ Great storytelling involves breaking down complex data into understandable and engaging segments.
  Use visuals and analogies to make your points clear.

5. Inspire Action
  ↳ Your story should lead to a call to action, encouraging your audience to make informed decisions based on your insights.
  
Remember, data storytelling isn't just about presenting facts—it's about driving change.

By mastering the art of storytelling in data, you transform from a mere analyst to an influential data storyteller.

And the best part?

Anyone can learn this skill.

So, are you ready to craft stories that drive data-driven decisions?

Why I believe the future of data engineering lies not in new tech but in teaching empathy and communication.

I started in data engineering with the belief that the latest tech would solve every problem.

That mindset shifted.

Here's why: it's not just about the tools.

It's about understanding the humans behind the data.

In my journey from data analyst to data engineering leader, I've learned that the hardest problems aren't technical.

They're human.

When I was tasked with transforming raw data into insights, I quickly realised that many organisations were drowning in fragmented data.

Not because they lacked technology, but because they lacked communication.

→ Data was siloed.

→ Teams didn't talk to each other.

→ Processes were inefficient.

So I focused on:

1. Building Bridges: I brought together diverse teams, ensuring everyone understood the data's value and purpose.

2. Teaching Empathy: I encouraged my team to see data not just as numbers but as stories with human impact.

3. Enhancing Communication: I led efforts to develop clear channels and languages for data discussions, making complex insights accessible to all.

It wasn’t just about algorithms.

It was about collaboration.

About understanding the fears and hopes of those who rely on the system.

When we embrace empathy and communication, we transform data from a static resource into a dynamic force for change.

We give it life.

The future of data engineering won't be about the flashiest tools.

It will be about the human touch.

So here's my challenge to you:

Focus on the human side of data.

Ask more questions.

Listen more.

Let's build a future where data brings us together, not keeps us apart.

What do you think?

How can we make data engineering more human?

Smart Treasury for Internet Capital Markets (ICM)

TRUSTBYTES turns behavioural analytics into capital efficiency for wallet-based businesses.
‍
☑ Capture opportunities
☑ Comply effortlessly
☑ Command your crypto treasury operations

We believe that internet/institutional capital markets (ICM) should be proactive, not reactive.
‍
In 24/7 crypto markets, your treasury, compliance and operation teams can't be awake around the clock fighting fires.
While traditional finance sleeps, crypto never does.
Why losing money on idle capital, failing compliance checks, and burning out their teams with manual processes, when there is a different way?
‍
The cost of inaction is measured in Billions per month.

We replace static rules with intelligent, dynamic policies.

Instead of threshold-based systems that trigger alerts at 3:11 AM, we use predictive intelligence to:

☑ Anticipate liquidity needs before they become urgent
☑ Automatically rebalance wallets during the most optimal time windows
☑ Maintain compliance ratios proactively, not reactively
☑ Transform your existing wallet infrastructure into a smart, learning system 

TRUSTBYTES works 24/7 so your team doesn't have to.

Nobody's betting on you - until you make it impossible not to.⤵


1/
➠ You don’t get funded. You get noticed.

➝ Markkula wasn’t hunting startups.
➝ Jobs hounded his way into a meeting.
↳ 150 calls to Valentine forced the door open.

➝ Most founders wait to be discovered.
➝ The bold demand to be seen.
↳ Obsession always beats talent waiting quietly.

➝ Investors chase proof of belief.
➝ Hustle is the first product.
↳ Persistence is louder than pitch decks.


2/
➠ The garage wasn’t a liability. It was proof.

➝ They had traction - six stores already.
➝ Apple II wasn’t vaporware.
↳ Launch was close enough to taste.

➝ Resource-starved but progress-rich.
➝ Not built to impress.
↳ Built to ship.

➝ The myth: start perfect.
➝ The truth: start moving.
↳ Results raise eyebrows, not resumes.


3/
➠ Markkula didn’t just invest - he calculated.

➝ $90K seed at $300K valuation = serious skin.
➝ Asked for a $250K credit line.
↳ 10% interest. Paid post-revenue.

➝ Investors protect upside.
➝ Smart money isn’t charity.
↳ Terms matter as much as dollars.

➝ Founders focused on “enough.”
➝ Markkula focused on “what’s next.”
↳ He knew scale eats capital.


4/
➠ The pitch didn’t win the day. The look did.

➝ “I’ve seen that look. I had it myself.”
➝ Markkula bet on the fire.
↳ No spreadsheet for conviction.

➝ Investors sense belief.
➝ They smell desperation.
↳ Vision makes you unforgettable.


5/
➠ Build something that makes “no” look stupid.

➝ No one believed in Apple.
➝ Until one man saw the future.
↳ Then everyone saw it.

➝ Don’t just get in the room.
➝ Make the room remember you.
↳ That’s how legends are built.


Think it through...

▶ What if they never made those 150 calls?
▶ What if the garage was enough?
▶ What if no one said yes?


That's the mindset you have to have.
That's the mindset we as founders are adopting at TRUSTBYTES (Techstars '25).

Unpopular opinion:
Work should fit into Life - not consume it.
⤵

You’ve been sold a lie.
"Work harder. Hustle longer. Sacrifice now."

But here’s the truth:
You don’t get a trophy for burning out.

Work is a tool - not your identity.
It belongs inside your life, not wrapped around it.

 
1/
➠ When Work Becomes Life

When work takes over, life gets boxed in.
➝ Rest feels wrong
↳ You see it as lazy

➝ Loved ones feel intrusive
↳ You call it "distractions"

➝ Joy gets postponed
↳ Always chasing the next win

You’re not fulfilled.
You’re just drained.


2/
➠ When Life Is Bigger Than Work

Now flip it.
Make life the frame. Let work sit inside it.

➝ You still care about work
↳ But not at life’s expense

➝ You rest, recharge
↳ And show up sharper

➝ You celebrate wins
↳ With people who matter

You’re no longer sacrificing.
You’re thriving with clarity.


3/
➠ Why This Matters More Than Ever

Everything changes fast.
Your title isn’t forever. Your wellbeing should be.

➝ Careers shift
↳ Roles vanish

➝ Companies change
↳ Titles fade

➝ Health, peace, love
↳ That’s the real legacy

Invest in what actually lasts.


4/
➠ Two Simple Power Moves

Don't overthink balance.
Build it into your daily routine.

➝ Guard your "Life anchors"
↳ Treat them as sacred meetings

➝ Create a daily work stop
↳ Define your off switch

Discipline in boundaries
creates freedom in life.


Final Thought:
Work is part of your life.
Not the point of your life.

If your life is a circle,
Make sure work isn’t the whole thing.

▶ What if burnout is self-inflicted?
▶ What if rest is the cheat code?
▶ What if “balance” isn’t soft, but strategic?

Growth happens in the space between who you are
and the person you were meant to be.
 ⤵

Before anything else, here’s the angle most people miss:

You’re not competing with the world.
You’re competing with the next version of you.

And that competitor never gets tired...

That’s why the chase matters more than the milestone.

That's what Matthew McConaughey knew well an led to more than "just" an Oscar win:


1/
➠ The future self that never stops moving

 ➝ Your hero stays ten years ahead
 ↳ Always further
 ↳ Always better
 ↳ Always out of reach

We start here because this is the foundation: the future version of you isn’t a trophy. It’s a target that refuses to stand still.


2/
➠ Time reshapes who you want to become

 ➝ Growth shifts your definition of “ideal”
 ↳ New standards
 ↳ New clarity
 ↳ New goals

And as time moves, so do you.
Your definition of “better” evolves because you evolve.


3/
➠ Self-reflection keeps you honest

 ➝ Checking progress reveals the truth
 ↳ What’s working
 ↳ What’s missing
 ↳ What’s next

This is where the internal audit comes in.
No sugar-coating. 
No excuses. 
Just a clear view of where you stand.


4/
➠ The unattainable target is the useful one

 ➝ You’re not meant to catch your hero
 ↳ It stretches you
 ↳ It humbles you
 ↳ It disciplines you

The point isn’t arrival.
The point is pursuit.
The chase creates the growth.


5/
➠ Who you chase shapes who you become

 ➝ Aim at a version worth becoming
 ↳ More aligned
 ↳ More intentional
 ↳ More fulfilled

Because in the end, the future you becomes the architect of your present decisions.
And that’s where real transformation happens.


The standards of your future self
slowly become the standards of your current life.

If the person you were meant to be is still ahead of you,
what does that demand from you today?

8 Small Shifts That Will Solve 80% Of Your Problems
⤵


Sometimes, we look for big solutions when it’s the small tweaks that unlock the biggest doors.


These shifts aren’t radical. 
They’re practical. 
And that’s why they work.


Let’s break them down - one shift at a time:


1/
➠ Assume People Have Good Intentions
➝ You can’t read minds
↳ So stop acting like you can

➝ Bad assumptions drain peace
↳ Good ones open connection

➝ Choose belief over suspicion
↳ It hurts less


2/
➠ Avoid Using Negative Words
➝ “I can’t” is mental trash
↳ Stop repeating failure

➝ Language programs mindset
↳ Every word counts

➝ Talk trash - live trash
↳ You’re better than that


3/
➠ Celebrate More Frequently
➝ Wins deserve space
↳ Big or small

➝ Acknowledge before you rush
↳ Growth needs pause

➝ Clap for yourself
↳ Even quietly


4/
➠ Decide You Must Achieve Your Goals
➝ “I’ll try” gives you a backdoor
↳ Close it

➝ Use “I must” instead
↳ Power lives there

➝ Remove wriggle space
↳ Clarity follows


5/
➠ Define “Failure” as “Failing to Take Action”
➝ No action = real failure
↳ Movement matters

➝ You control effort
↳ Not outcome

➝ Stop fearing results
↳ Start moving


6/
➠ Don’t Waste Energy on Hate
➝ Hate is self-harm
↳ Drains your life

➝ Fix it or drop it
↳ No middle

➝ Forgive. Forget. Move.
↳ Heal faster


7/
➠ Don’t Take Yourself So Seriously
➝ Laugh at yourself
↳ Or others will

➝ Humor builds influence
↳ People follow lightness

➝ Lighten up
↳ Power lives here


8/
➠ Don’t Try to Win Every Argument
➝ Not every battle is worth it
↳ Let some go

➝ “Winning” is ego
↳ Choose strategy

➝ Ask what’s next
↳ Then lead


Big shifts start small.
Start here. Start now.


▶ What shift have you avoided the longest?
▶ What would change if you only applied one?
▶ What would happen if you applied all eight?
