Dev Focus & Passions

Passion for AI Integration

I’m excited by AI's power to revolutionize user experiences. My mission? To weave AI seamlessly into web apps, supercharging functionality, personalization, and automation. From harnessing the magic of OpenAI and Microsoft Azure AI to experimenting with CloudFlare Workers, I’m thrilled by the endless possibilities AI offers for creating cutting-edge apps.

Specialization in SaaS

SaaS is where I shine! I love crafting scalable, user-friendly solutions that make a real impact. My goal is to build systems that are not only efficient but also a blast to use. By focusing on seamless experiences and continuous improvement, I get to blend creativity and functionality, making SaaS both fun and effective.

Creativity Through Crafting

I love creating beautiful, exciting projects that work out my creative muscles. It’s like a workout for my imagination—combining sleek design with functionality. As a former actor, channeling my creativity into building something impressive gives me a stage to shine and a product to be proud of.

Love for Learning New Technologies

I thrive on exploring new tech, from CloudFlare Workers and Microsoft Azure to GitHub Copilot and the latest UI libraries. I get excited about discovering the latest innovations and trying them out for myself. Hearing about new tools from the developer community and diving into them is one of my favorite parts of being a developer.
