I ​am a global technology executive with over 20 years of experience. I am currently Director of Software Engineering at Amazon, leading the Technology function for Payments across the Middle East and Africa. In this role, my aim is to make the payment experience of our merchants (Amazon Payment Services) and customers (Stores) the most simple, affordable, and trusted.

Over my career, I'm honored to have delivered award-winning transformational initiatives that have created competitive advantage, enabled business growth, and exceeded customer expectations.

Known as a forward-thinking problem-solver ― skilled in both business and technology strategy ― I adapt and plan for evolving market needs, delivering initiatives with speed and agility. I am also deeply passionate about building, developing, managing, and leading high-performance teams. A strong communicator and relationship builder, I partner effectively with cross-functional stakeholders and am a trusted advisor within the company.

Ever since I stepped into my first managerial role, more than a decade ago, I quickly realized the profound impact strong leadership has on individuals, teams, and organizations. From that moment, I made it my mission to empower others in their leadership journeys, guiding them to reach new heights in their careers.

In support of this mission, I have developed a community on LinkedIn of over 70K+ like-minded professionals with whom I actively support, engage, and share daily content on leadership, management, and career. I have been recognized as a LinkedIn Top Voice (Blue Badge) and ranked #1 LinkedIn Arab World Creator in Management and Leadership. 

Outside of work, I am passionate about everything automotive, especially F1 racing (Forza Ferrari!). I enjoy sports in general, both playing and watching. I also have a keen interest in collecting fragrances, working out with a focus on strength training, and all things food—from learning about it and exploring new cuisines to preparing dishes and hosting gatherings. However, my favorite pastime is spending quality time with my family.

Most career advice is about standing out.
This is about showing up.

Consistently. 
Predictably. 
Without drama.

Reliability is the most underrated career skill.

It's not glamorous. 
It won't trend on social media. 
And there's no 'Reliability 101' course.

But your career grows at the speed of people's confidence in you.

Not your talent. 
Not your ambition. 
Not your potential.

Your reliability.

It’s the quiet skill that opens doors long before titles, certifications, or even experience do.

5 practical ways to build reliability — starting today:

1/ Always Close the Loop

When someone asks for something, acknowledge it and follow through. 
Most careers get derailed not by mistakes, but by silence.

2/ Do What You Say — When You Say It

Consistency beats capability. 
If you commit to less but deliver every time, people will trust you with more.

3/ Communicate Early (Especially When Behind)

Falling behind isn’t the problem. 
Surprising people is.
Let others know early — it builds trust.

4/ Create a Personal Operating Rhythm

Reliability isn’t innate — it’s engineered. 
Weekly planning, structured 1:1s, documented decisions. 
You rise to the level of your systems.

5/ Make Your Work Visible

Share progress before you're asked. 
Visibility doesn’t just build trust — it reinforces your momentum.

Reliability won’t get you applause. 
But it will get you opportunities.
It’s not a soft skill — it’s a career advantage.

What’s helped 𝘺𝘰𝘶 stay reliable?

Tech Director @ Amazon | I help professionals lead with impact and fast-track their careers through the power of mentorship

You're mid-sentence in a meeting. 
Someone cuts you off. Again. 
You smile, stay quiet, and lose your voice.

If you accept interruptions, you train others to ignore you.  

I've been in thousands of meetings over my career. 
Led teams. 
Presented to executives. 
Eventually became Director of Software Engineering.  

One pattern I’ve seen? 
People who get heard set boundaries.

7 (proven) ways to stop people from interrupting you:  

1/ Ask to continue  

When someone jumps in: pause, make eye contact. “If it’s alright, I’d like to finish my thought first.” 

Clear. Polite. Assertive.  

2/ Acknowledge, then steer back  

Let them finish. 

Then: “Thanks—let me quickly finish what I was saying.” 

Respectful but firm.  

3/ Set expectations upfront  

Start strong: “Feel free to note questions—we’ll tackle them during Q&A.” 

You set the rules.  

4/ Keep it short  

The longer you talk, the more chances to be cut off. 

Be direct. Be organized. Be done.  

5/ Use the right tools  

In Zoom? Use the ‘raise hand’ feature to stay organized. 
 
Chat for sidebar questions.

6/ Let your body do the talking  

Eye contact. Small hand raise. Keep talking. 

They’ll get the message. 

Confident body language stops interruptions before they start.  

7/ Provide feedback privately  

Most interrupters don’t even realize. 

After the meeting: "During the meeting, I felt I was being cut off a few times. I'd appreciate the chance to finish my points next time." 

Direct. Respectful. Problem solved.  


These work. I’ve used every one.  
Your voice matters. So do your ideas. 
Don’t let interruptions steal that.  

👉 Which tactic will you try today?  

PS: Someone getting interrupted? Step in. “Let’s hear the rest of what Sarah was saying.” That’s leadership.

Assumptions feel fast.    
But they’re also where trust breaks — and where judgment slips
  
Most professionals don’t stagnate because they lack skill.  
They stagnate because they believed they already knew.
 
You’ve seen the pattern.  
You’ve done this before.  
You trust your gut...  
So you stop asking questions.
 
That’s when mistakes happen.  
And that’s when trust quietly erodes.
 
If you want to be right a lot — and earn trust — lead with a question.

A single question can prevent:  
• Delivering the wrong thing  
• Misunderstanding what someone actually meant  
• Missing a risk that was obvious to others  
• Overlooking a dependency that derails everything
 
Early in your career, you’re rewarded for answers.
Later in your career, you’re rewarded for clarity —  
and clarity comes from questions.
 
→ “𝘞𝘩𝘢𝘵 𝘮𝘪𝘨𝘩𝘵 𝘐 𝘣𝘦 𝘮𝘪𝘴𝘴𝘪𝘯𝘨?”  
→ “𝘞𝘢𝘭𝘬 𝘮𝘦 𝘵𝘩𝘳𝘰𝘶𝘨𝘩 𝘩𝘰𝘸 𝘺𝘰𝘶 𝘨𝘰𝘵 𝘵𝘩𝘦𝘳𝘦.”  
→ “𝘏𝘦𝘭𝘱 𝘮𝘦 𝘶𝘯𝘥𝘦𝘳𝘴𝘵𝘢𝘯𝘥 𝘸𝘩𝘢𝘵 𝘺𝘰𝘶’𝘳𝘦 𝘰𝘱𝘵𝘪𝘮𝘪𝘻𝘪𝘯𝘨 𝘧𝘰𝘳.”
 
Better questions → better inputs → better decisions → more trust.
 
A statement closes the conversation. 
 A question opens it.
 
If you want to be trusted, ask better questions.
If you want to be right a lot, ask more questions — 
especially when you think you already know.
 
𝗣𝗦: Curiosity isn’t slowness.  It’s strategy.

What's your go-to question to avoid making assumptions?

Your calendar’s full.  
That’s the problem.

The thing you’re missing isn’t another meeting, another project, or another ‘alignment call.’
 
It’s slack — not the tool, the white space.

I used to treat it as waste.  
Empty time made me anxious, so I filled it.  
I felt productive — but I stayed stuck.  

In a world obsessed with productivity, slack is a leadership and career superpower:
  
𝟭/ 𝗦𝗹𝗮𝗰𝗸 𝗶𝗻𝗰𝗿𝗲𝗮𝘀𝗲𝘀 𝘆𝗼𝘂𝗿 𝘀𝘁𝗿𝗮𝘁𝗲𝗴𝗶𝗰 𝗮𝗹𝘁𝗶𝘁𝘂𝗱𝗲
 
If every hour is packed, you have no mental space to zoom out, connect dots, or think long-term.  You rise when you create the space to 𝘵𝘩𝘪𝘯𝘬, not just to 𝘳𝘦𝘢𝘤𝘵.
 
𝟮/ 𝗦𝗹𝗮𝗰𝗸 𝗶𝘀 𝗵𝗼𝘄 𝘆𝗼𝘂 𝗽𝗿𝗲𝘃𝗲𝗻𝘁 𝗳𝗶𝗿𝗲𝘀 — 𝗻𝗼𝘁 𝗷𝘂𝘀𝘁 𝗳𝗶𝗴𝗵𝘁 𝘁𝗵𝗲𝗺
 
Most “urgent problems” aren’t surprises.  They’re early signals we were too busy to notice.  Slack gives you the margin to catch issues before they blow up.
 
𝟯/ 𝗦𝗹𝗮𝗰𝗸 𝗺𝗮𝗸𝗲𝘀 𝘆𝗼𝘂 𝗺𝗼𝗿𝗲 𝗮𝘃𝗮𝗶𝗹𝗮𝗯𝗹𝗲 — 𝗮𝗻𝗱 𝗮𝘃𝗮𝗶𝗹𝗮𝗯𝗶𝗹𝗶𝘁𝘆 𝗯𝘂𝗶𝗹𝗱𝘀 𝘁𝗿𝘂𝘀𝘁
 
If your team can never find you, they stop coming to you.  Slack lets you be present in the right moments:  The quick checkpoint.  The 5-minute unblock.  The conversation that prevents a misunderstanding.
 
𝟰/ 𝗦𝗹𝗮𝗰𝗸 𝘁𝘂𝗿𝗻𝘀 𝘆𝗼𝘂 𝗳𝗿𝗼𝗺 𝗼𝗽𝗲𝗿𝗮𝘁𝗼𝗿 → 𝗺𝘂𝗹𝘁𝗶𝗽𝗹𝗶𝗲𝗿
 
When you're maxed out, you execute.  When you have slack, you coach, delegate, and develop people.  That’s how you scale yourself — and your career.
 
𝟱/ 𝗦𝗹𝗮𝗰𝗸 𝗶𝗻𝗰𝗿𝗲𝗮𝘀𝗲𝘀 𝘆𝗼𝘂𝗿 𝗾𝘂𝗮𝗹𝗶𝘁𝘆 𝗼𝗳 𝗱𝗲𝗰𝗶𝘀𝗶𝗼𝗻𝘀
 
Rushed leaders make reactive decisions.  Calm leaders make clear decisions.  Slack is a buffer between stimulus and response — and clarity lives in that buffer.
 
𝟲/ 𝗦𝗹𝗮𝗰𝗸 𝗽𝗿𝗼𝘁𝗲𝗰𝘁𝘀 𝘆𝗼𝘂𝗿 𝗲𝗻𝗲𝗿𝗴𝘆 (𝗮𝗻𝗱 𝗲𝗻𝗲𝗿𝗴𝘆 𝗶𝘀 𝘆𝗼𝘂𝗿 𝘁𝗿𝘂𝗲 𝗰𝗼𝗺𝗽𝗲𝘁𝗶𝘁𝗶𝘃𝗲 𝗮𝗱𝘃𝗮𝗻𝘁𝗮𝗴𝗲)
 
Back-to-back intensity burns out even the strongest performers.  Slack helps you sustain output — consistently and predictably.
 
But slack is hard.  
It forces you to say no. 
Set boundaries.  
Let go of the illusion of busyness.  
And sit with space.
 
It's a skill - and like any skill, it takes practice.
 
So start small.
Try 30 minutes of unbooked time. 
No agenda. Just space.  
Then notice what changes — in your focus, your energy, your decisions.

Your future self — and your team — will thank you.
