After nearly five years in IT, I’ve worked across roles—as an SDET, a developer, and now a platform engineer. Along the way, I didn’t just write tests or build features. I experienced the full lifecycle of software, including all the friction that comes after development.
And that changed everything.
The Problem I Kept Running Into
As an SDET and developer, my job didn’t end after writing code. Every issue meant going through the same painful cycle:
- Build the application
- Deploy it to an environment
- Run tests and validate
- Debug and repeat
This process could easily take an entire day.
The hardest part? I didn’t fully control it.
If something broke at night, I had to wait for SREs, DevOps, or DBAs. Permissions, access, and dependencies slowed everything down. Fixing a small issue often required multiple teams to be available.
That’s when I realized:
The real bottleneck wasn’t code, it was the system around the code.
What SDET Taught Me
Being an SDET gave me a strong foundation in:
- Thinking about edge cases and failure scenarios
- Building robust automation frameworks
- Ensuring quality at every stage
- Designing systems that are testable by default
I didn’t just test software, I learned how software breaks.
What Development Taught Me
As a developer, I learned:
- How to design and build scalable systems
- Writing clean, maintainable code
- Understanding architecture and performance
- Shipping features with real user impact
I didn’t just find problems, I built solutions.
Where It All Came Together: Platform Engineering
Platform engineering became the natural next step.
Instead of repeatedly fixing issues inside the same broken process, I started focusing on improving the process itself.
Today, I build platforms that:
- Automate the entire build, test, and deployment lifecycle
- Enable self-service deployments for developers
- Reduce dependency on multiple teams
- Provide consistent environments across development, staging, and production
In short, I don’t just build software anymore. I build systems that help others build software faster.
The Advantage of SDET + Developer Experience
Having both backgrounds is a huge advantage in platform engineering:
1. You Build with Quality in Mind
You don’t treat testing as an afterthought. You design platforms where quality checks are built-in.
2. You Understand the Full Lifecycle
From writing code → testing → deploying → monitoring—you’ve lived every step.
3. You Reduce Friction for Teams
You know where developers and testers struggle, so you design platforms that remove those pain points.
4. You Automate What Actually Matters
Not just scripts, but meaningful automation that saves hours or days of effort.
5. You Think in Systems, Not Just Code
You move from solving isolated problems to improving the entire engineering workflow.
Why Platform Engineering is the Future
Modern software development is no longer just about writing code- it’s about delivering it quickly, reliably, and at scale.
Platform engineering enables that by:
- Turning infrastructure into self-service
- Using Infrastructure as Code for consistency and speed
- Eliminating manual handoffs and delays
- Empowering developers to own their code in production
As systems grow more complex, the teams that win will be the ones who can ship faster without sacrificing quality.
And that requires strong platforms.
Final Thoughts
Looking back, being both an SDET and a developer wasn’t just part of my journey; It was my biggest advantage.
It taught me how to think about quality, build scalable systems, and most importantly, identify the real bottlenecks in software delivery.
Because in the end:
Great engineers don’t just write code—they build systems that make everything else faster.
And that’s what "platform engineering" is all about.
