About me

Need a problem-solver who understands users and makes ideas happen?

I started my career as a digital marketer, where I learned that the best solutions come from truly understanding people and their needs.
Now, as a developer, I find joy in solving real problems, delivering seamless services, and collaborating with my team to create meaningful solutions.

I am proactive, detail-oriented and always keep the end user in mind.
I understand team goals and work with a professional mindset to drive meaningful results.

📌 Here’s a quick snapshot of me :

Backend-focused: PHP, Java, ASP.NET(C#).
Problem solver: Proactive, passionate, and driven.
Team player: Strong collaboration skills honed in marketing.
Lifelong learner: Fearless in taking on new challenges.

When I’m not coding, you’ll find me on Medium discussing tech or on GitHub sharing my latest projects. You can follow me on Linkedin where I share tech-related tips and build in public, or check out my work on GitHub.
