William Denzel Abelle Otieno
I am a Software and Blockchain Developer specializing in smart contract development, decentralized systems, and full-stack web applications. With practical experience building Web3 solutions using Solidity, Foundry, Next. js, and Type Script, I focus on writing clean, secure, and efficient code.
By combining my technical skills with a solid background in data tracking, process optimization, and systems administration, I bring a structured and analytical approach to software engineering. I am actively looking for a junior developer role where I can contribute to building secure and scalable technology solutions.
