A Decade of Growth, Challenges, and Lessons in Data
This year marks a major milestone for me: 10 years in the data and analytics industry. Over the past decade, I’ve had the privilege to work across various domains, lead talented teams, implement large-scale cloud architectures, and help organizations transform raw data into strategic advantage.
Along the way, I’ve learned some tough lessons, gained new perspectives, and uncovered a few non-obvious insights that have shaped my journey. Here are the 10 most important lessons I’ve learned in these 10 years:
1. Business Comes First, Always
No matter how cutting-edge your data pipeline or dashboard is, if it doesn’t drive business outcomes, it’s just technology. Focus on the impact first.
2. Data Without Governance is a Liability
You don’t need hundreds of policies, but you do need clear ownership, accountability, and governance practices from the start.
3. The Best Tools Are the Ones People Actually Use
Adoption beats perfection every time. Sometimes Power BI wins over Tableau simply because it’s more accessible. Simplicity and usability matter more than bells and whistles.
4. You Don’t Need to Be a Data Scientist to Deliver Machine Learning Value
Business-focused ML is about small, well-built models with solid features and a deep understanding of the problem, not necessarily complex algorithms.
5. Master Data Management (MDM) Is Not a Project, It’s a Discipline
MDM isn’t just a technology implementation; it requires change management, cross-functional collaboration, and ongoing ownership.
6. Soft Skills Multiply Your Technical Value
Explaining your work clearly to non-technical stakeholders is as valuable as writing optimized SQL queries or building robust data pipelines.
7. Build to Scale, Not to Impress
Avoid overengineering. Use proven, scalable patterns that can be maintained and evolved rather than flashy one-off solutions.
8. Documentation is a Superpower
The difference between good and great engineers often comes down to documentation. Without it, knowledge becomes siloed, and progress slows.
9. Data Is Change Management in Disguise
Every new dashboard, process, or platform changes how people work. Accounting for the human side is critical for success.
10. The Journey Is the Reward
Tools, roles, and industries will evolve, but your hunger to learn, adapt, and grow is what keeps you relevant and successful.
In the coming months, I will be sharing insights and stories around data engineering, analytics leadership, machine learning, data governance, career growth, and much more. If you’ve worked in data, I’d love to hear from you: What’s one lesson your career has taught you?
Thanks for reading — and here’s the next chapter in our data journeys!
