Junior Backend Development

I am a Full-Stack Developer with a strong foundation in React, TypeScript, Python, and Go, eager to transition my coding skills into the Web3 space. While my commercial experience is currently rooted in Web2, my appetite for learning decentralized technologies is massive. I have hands-on experience building robust REST APIs, containerizing infrastructure with Docker, and developing responsive frontends. Furthermore, my nearly three-year background in Business Security has ingrained in me a deep appreciation for secure, scalable systems—a crucial mindset for blockchain development. I am looking for a junior role where I can study intensely, contribute to innovative dApps or protocols, and add immediate value through hard work and adaptability.
