2. Led Innovative Projects: At NATS, I contributed to the world's first AI system for air traffic control, utilising digital twinning and machine learning.
3. Developed Future Talent: Shaped data science and engineering education at Multiverse by developing comprehensive curricula for degree-level apprenticeships.
4. Consulted on High-Impact Projects: Provided AI and data science consultancy for industry giants like BP, Sword and Chaucer (now BIP UK), driving data-driven decision-making and innovation.

Now, I'd like to talk about you.

Are you aspiring to become a successful data analyst/data scientist/data engineer but need help figuring out where to start?

Here's a roadmap to guide you:

Cloud Computing Tutorial

In a crowd of opinions, the softest voices often carry the deepest insights.

This message, inspired by Dora Vanourek, truly resonates.

Here’s what introverts wish leaders said in meetings:
(and a few things not to say):

✅ "Let's take a moment to think this through."
↳ Introverts need time to process before speaking.
↳ This approach gives everyone a chance to reflect.
↳ It leads to more thoughtful and meaningful input.

✅ "If you have further thoughts, email them to me."
↳ Introverts often think of their best ideas later.
↳ Written communication can be more comfortable.
↳ Ensures valuable insights aren't missed after the meeting.

✅ "We'll discuss XYZ next time. Bring your ideas."
↳ Provides time for introverts to prepare and reflect.
↳ Encourages thoughtful contributions in future discussions.
↳ Boosts confidence in sharing ideas during the meeting.

❌ "You are so quiet today."
↳ Quietness doesn’t mean disengagement.
↳ Comments like this can feel judgmental.
↳ It’s better to appreciate different communication styles.

❌ "Try to be more outgoing in meetings."
↳ Suggests their natural style is wrong.
↳ Not everyone is comfortable speaking on the spot.
↳ Emphasizes extroverted behavior as the standard.

❌ "Everyone share a fun fact about themselves!"
↳ Personal sharing can be uncomfortable.
↳ Introverts may feel stressed or pressured.
↳ Creates anxiety rather than fostering connection.

True leaders don’t just listen to the loudest voices.
They create space for those who often go unheard.

Respecting different communication styles fuels collaboration.
Let’s build inclusive cultures where everyone thrives.

How do you ensure all voices are heard in your meetings?

7 Clear Signs You’re Being Undervalued at Work:

(And what to do about it)

1.	You’re Excluded from Decisions
↳ Major decisions are made without your input.
↳ This makes you feel sidelined and unimportant.
↳ Being part of key discussions should be the norm, not the exception.

2.	They Give You Busywork, Not Impactful Projects
↳ You’re handed small, non-impactful tasks while others take on critical projects.
↳ Your potential is being wasted on work that doesn’t move the needle.
↳ Push for projects that align with your strengths and goals.

3.	You’re Not Set Up to Succeed
↳ You lack the resources, support, or clarity needed to perform well.
↳ This leads to frustration and sets you up for failure.
↳ Success requires the right tools and direction—don’t settle for less.

4.	Your Role Expands Without Rewards
↳ You’re constantly taking on more responsibilities, but your title and pay stay the same.
↳ If you’re doing more, you deserve to be compensated accordingly.
↳ Speak up about aligning your role with fair recognition.

5.	No Recognition for Your Hard Work
↳ Your contributions go unnoticed, and there’s no appreciation for what you do.
↳ Recognition is key for morale and motivation, and everyone deserves it.
↳ It’s time to request regular feedback and acknowledgment.

6.	Your Growth Stalls
↳ You’re not being given opportunities to develop new skills.
↳ If you feel stuck, it’s a sign your potential isn’t being nurtured.
↳ Start exploring options that align with your growth ambitions.

7.	Inadequate Compensation
↳ Your salary doesn’t reflect your contributions to the company.
↳ If others in similar roles are being paid more, it’s time to negotiate.
↳ Know your worth and advocate for fair compensation.

Feeling undervalued can be draining, 
but recognizing the signs is the first step to change.

The 8 Software Development Life Cycle Models You Should Know

Choosing the right software development model can significantly impact the success of your project. 

Here are 8 SDLC models and when you should consider using them:

1.	Waterfall
↳ Sequential phases: design, build, test, deploy.
↳ Best for projects with clear, unchanging requirements.
↳ Simple but rigid—ideal for small projects.

2.	Spiral
↳ Iterative and risk-driven approach with continuous refinement.
↳ Useful for complex projects that involve high risk and frequent changes.
↳ Allows for continuous evaluation and improvement.

3.	Agile
↳ Focuses on delivering incremental updates through short sprints.
↳ Ideal for projects requiring flexibility and collaboration.
↳ Prioritizes customer feedback and adaptive planning.

4.	Iterative
↳ Builds software in iterations, improving with each cycle.
↳ Great for large projects that need continuous refinements.
↳ Each iteration includes design, testing, and implementation.

5.	V-Model
↳ Developers and testers work in parallel—strict validation and verification process.
↳ Best for projects where validation at each step is essential.
↳ Ensures thorough testing before progressing to the next phase.

6.	Incremental
↳ Delivers the software in smaller, manageable increments.
↳ Ideal for large projects where full deployment isn’t feasible from the start.
↳ Each increment brings a working version closer to the final product.

7.	Big Bang
↳ Everything is developed at once—no formal planning.
↳ High risk but suitable for small projects or experimental prototypes.
↳ Requires significant time and resources upfront.

8.	Rapid Application Development (RAD)
↳ Focuses on quick development and frequent iterations through prototypes.
↳ Best for projects with tight deadlines or evolving requirements.
↳ Encourages user feedback and fast adaptation to changes.

Missing these can seriously affect your results. To maintain its accuracy, validate your data relentlessly.

2. Scalability is Key
Failing to plan for growth will eventually clog up your pipeline. Always design with expansion in mind to keep things running smoothly.

3. Monitoring & Alerting:
Implement monitoring tools and set alerts to catch and squash bugs as soon as possible.

4. Keep Transformations Simple
Complications aren't always better. Aim for sleek, simple transformations to avoid unnecessary headaches.

5. Documentation is your Best Friend
Don't leave your team guessing. Clear, comprehensive documentation saves time and sanity.

By dodging these common errors, you're on your way to creating top-notch, robust ETL pipelines that stand the test of time.

Remember, perfection is a journey. Keep refining your craft and embracing the ever-changing data landscape.

>> NVIDIA just changed self driving forever.

And most people missed why.

With 𝗔𝗹𝗽𝗮𝗺𝗮𝘆𝗼, NVIDIA introduced the first autonomous vehicle system that does something new.

It reasons.

Until now, self driving systems saw the world and reacted.
Detect object.
Trigger rule.
Execute maneuver.

Alpamayo adds a missing layer.
𝗣𝗲𝗿𝗰𝗲𝗽𝘁𝗶𝗼𝗻 → 𝗿𝗲𝗮𝘀𝗼𝗻𝗶𝗻𝗴 → 𝗮𝗰𝘁𝗶𝗼𝗻.

In the demo, the car does not just slow down.
It explains why.

Why a pedestrian looks uncertain.
Why a construction zone changes priorities.
Why yielding now reduces future risk.

That explanation layer unlocks everything.

- 𝗗𝗲𝗯𝘂𝗴𝗴𝗶𝗻𝗴.
- 𝗧𝗿𝘂𝘀𝘁.
- 𝗥𝗲𝗴𝘂𝗹𝗮𝘁𝗼𝗿𝘆 𝗮𝗽𝗽𝗿𝗼𝘃𝗮𝗹.

Autonomy does not fail at 80 percent.
It fails at 99 percent.

The last one percent is where accidents live.
Reasoning is how you attack it.

This is not just about cars.
It is the beginning of 𝗽𝗵𝘆𝘀𝗶𝗰𝗮𝗹 𝗔𝗜.

Are we ready for machines that can explain their decisions?

>> Apple is not behind in AI.

Apple is quietly building AI infrastructure.

Look at the photo.
Dozens of Mac minis, racked and wired like a mini data center.

Not for web apps.
For running models locally.

For years the narrative was simple.

- No frontier model.
- No flashy chatbot.
- No arms race.

But Apple optimized for something else.

𝗟𝗼𝗰𝗮𝗹 𝗶𝗻𝘁𝗲𝗹𝗹𝗶𝗴𝗲𝗻𝗰𝗲.
Unified memory.

- High memory bandwidth per euro.
- Hardware and OS designed as one system.

That combo unlocks a truth most AI discourse ignores.
Inference often loves 𝗺𝗲𝗺𝗼𝗿𝘆 more than raw FLOPS.

The real world is 𝗯𝗮𝘁𝗰𝗵 𝘀𝗶𝘇𝗲 𝟭.
Most workloads do not need a GPU furnace.

So developers are doing the obvious.
They scale horizontally with Macs.

They keep data private.
They run models offline.

They pay indie prices for enterprise capability.
The irony is perfect.

The company accused of doing nothing in AI
might become the company that makes AI boringly deployable.

Are we watching Apple “catch up” or watching Apple win the constraints game again?
