The Certification Debate
Every few months, the tech community erupts in the same debate: "Are certifications worth it?" Some say they're resume padding. Others swear they got hired because of them.
After earning 4 certifications over 2 years, I have a nuanced answer: it depends on which ones and why you're getting them.
The Ones That Helped
1. Azure Fundamentals (AZ-900) ✅
Why it helped: As a mobile developer, I had zero cloud knowledge. AZ-900 gave me enough understanding of Azure services to have meaningful conversations with backend teams. When we were designing the architecture for a new feature at PhonePe, I could actually contribute to decisions about Azure App Configuration and Cosmos DB.
ROI: High. The knowledge is broadly applicable, and the cert carries weight in enterprise contexts. It also opened the door to understanding our entire backend infrastructure.
Difficulty: Easy. 2 weeks of study, 1 hour exam.
2. Azure Data Fundamentals (DP-900) ✅
Why it helped: Understanding data pipelines, data lakes, and analytics services helped me build better analytics SDKs at Glance. I understood where the data my SDK collected actually went and how it was processed.
ROI: Medium-high. Particularly valuable if you work at the intersection of mobile and data.
Difficulty: Easy to moderate. 2-3 weeks of study.
3. GitHub Developer Certification ✅
Why it helped: This one surprised me. It wasn't just about Git commands — it covered GitHub Actions, security features, API usage, and collaboration patterns. I immediately improved our CI/CD pipeline and code review practices.
ROI: High. Every developer uses GitHub daily. Understanding it deeply makes you faster at everything.
Difficulty: Moderate. The Actions and API sections require hands-on practice.
4. Databricks Lakehouse Fundamentals ✅
Why it helped: This gave me credibility when proposing changes to our data collection SDK. Understanding how data is stored, queried, and transformed in a lakehouse architecture made my SDK designs more data-team-friendly.
ROI: Medium. Niche, but valuable if you touch data infrastructure.
The One That Didn't Help
5. [Redacted Popular Platform Cert] ❌
I won't name it to avoid drama, but I got a certification from a well-known online learning platform that promised "industry recognition." It didn't carry any weight in interviews. Nobody asked about it. Nobody cared.
Why it failed: No proctored exam. No hands-on component. Just multiple-choice questions after watching videos. Any cert without a rigorous assessment process is essentially a receipt for a course you completed.
My Framework for Choosing Certifications
- Does it fill a real knowledge gap? Don't certify in things you already know well.
- Is the exam proctored and rigorous? If anyone can pass it, it means nothing.
- Do hiring managers in your target companies recognize it? Ask people who work there.
- Will the knowledge be useful daily, not just on your resume? The best certs teach you things you use every day.
The Bottom Line
Certifications are not a substitute for real experience. But they are excellent for structured learning in areas outside your core expertise. As a mobile developer, cloud and data certifications expanded my ability to contribute beyond just the Android layer.
Don't collect certs like Pokémon. Choose strategically, learn deeply, and apply the knowledge immediately.
