Hi, I'm Richelle Pereira
A
Curious problem-solver and tech enthusiast. I'm passionate about backend development, automation, DevOps, and creating tools that simplify work, always eager to tackle tricky technical challenges and improve workflows.
About
I am a 4th year Computer Engineering Student at University of Toronto. I love transforming complex technical challenges into simple, elegant solutions that make a real impact. As a backend engineer with hands-on experience in several languages (i.e. Python, C++, NodeJS, Java, etc.), and cloud technologies. I specialize in building scalable systems, APIs, and automated workflows. I thrive on optimizing processes, streamlining deployments, and exploring ways to make teams more efficient. Outside of work, I'm a curious explorer—I enjoy painting, reading, and spending time outdoors. I love discovering new perspectives, learning continuously, and turning curiosity into creative ideas. I'm always excited to connect with fellow engineers, collaborate on innovative projects, and exchange ideas that push technology forward.
