Professional Summary

I'm an extroverted, driven, and empathetic full-stack developer with extensive mobile-first development experience and a passion for Web3 technologies. I craft aesthetically stunning interfaces that load instantly and leverage bleeding-edge technology to align with an organisation's needs and user-centric strategies.

I am actively seeking to join a relatively small, close-knit team that prioritizes its impact as a company over office politics.

My expertise extends into pivotal areas such as Web3, AI, SEO content optimization, and user-centered design. I aim to create solutions that benefit both businesses and the future of our children by harmonizing user needs with business objectives. I am open-minded and adaptable, willing to change direction based on new data to meet the evolving needs of the business.
