    Interests

    Apart from being a Software Developer, I love spending time outdoors, especially during the beautiful fall season in Toronto. I enjoy taking scenic walks to admire the changing leaves and visiting local parks to soak in the crisp, cool air.

    When I'm indoors, I immerse myself in history, mystery, and treasure hunt movies and TV shows. I also have a passion for cooking and experimenting with new recipes. Additionally, I dedicate a significant portion of my free time to exploring and learning about the latest advancements in cloud technologies and related fields.
