About

I am a Software Engineer formally trained as a Civil engineer and teacher. I'm currently part-time at Eastern University in their Masters in Data Science.

I love programming, creating, and my side gig is teaching police officers to pass their mathematics and language testing and interviews. I know HTML5, CSS3, Python3, JavaScript, React, Node, SQL, Go (lang), TypeScript, React-Native, and Angular.

I've been coding on the web since 2012. This has included making membership e-commerce websites for clients, creating and maintaining my own teaching website at Cognitive Results, as well as past experience working for another developer doing retainer work for clients.

I code consistently and I enjoy continuously upgrading my skills. Please see my GitHub portfolio

Testimonials

Megan Garwood

Megan Garwood Web Development

Gillian has been an integral part of my web development business since April 2019. She has shown outstanding commitment to our projects along with a strong sense of morality. She is hard working, dedicated, and often goes above and beyond what is required.

Gillian is loyal and conscientious towards others and is always the first to answer the call when problems need solving or projects need finishing. She is highly self-motivated, taking the initiative to get things done without needing my constant oversight.

I can attest that Gillian is diligent and thorough in all aspects of her work. Gillian is an invaluable asset to any team to which she belongs.
