Hi, I'm Sammy John Rawlinson, a full-stack developer passionate about crafting digital experiences and sharing insights from my IT journey.
In 2021, after a successful career in hospitality, I pivoted to tech during the pandemic, pursuing a Diploma and later a Bachelor's in Software and Web Development. Now, I'm eager to bring my skills to an internship or role while continuing to share my journey and accomplishments.
Through Teknabu, I aim to inspire and support others in tech by sharing knowledge, experiences, and innovations. Together, let's create, learn, and grow.
