Sophia Feona Cantiller

WritelySo was built on a simple belief: Good writing still matters, especially now.

I learned to love words early. I was the kid who lived in libraries, tore through books for fun, and started joining writing and journalism competitions before I knew what a byline was. Writing came first. Everything else followed.

Years later, that instinct turned into work. I’ve written and edited across industries, formats, and volumes. SEO articles, editorial pieces, ghostwritten content, and high-output publishing environments. Some of that work reached large audiences. Much of it did quieter, long-term work in search and structure.

Alongside writing, I studied computer science and machine learning. That background shapes how I approach content today. I understand how systems function, how large language models behave, and how modern workflows are built and maintained. I work comfortably with LLMs as part of the process, using them with intention, restraint, and a clear editorial standard.

At WritelySo, I lead strategy, writing, and editorial direction personally. When projects call for additional design or production support, I work with a small circle of close collaborators I’ve built alongside over time. People I trust, communicate with easily, and involve only when it adds real value. The voice stays consistent. The work stays focused.

The throughline has always been the same: clarity, context, and writing that holds up.

Testimonials

Katherine Ko

Sophia was an intern for Verité’s Communications Center in 2023. When her internship ended, we were so sad to see her go. Sophia carried out her work with impressive problem-solving skills that revealed her maturity, creativity and intelligence. She was quick, thorough, and managed to fix problems on our website through researching solutions. She has strong writing skills, agile graphic design abilities, and very solid knowledge of website content management systems. On top of all of this, she is entrepreneurial and a go-getter in every sense. I am very much looking forward to working with Sophia again in the future.

Sophia and her team helped me not only write, but format and illustrate a series of pop star books. These books went on to make over 15K in sales during Christmas, with raving 5 star reviews. I highly recommend her and her team.

Sophia is one of the best freelancers I've worked with. Quick, responsive, and open to feedback.

Sophia did an absolutely excellent job in editing my transcripts which became my book. Her communication style is kind, friendly and professional at the same time.

I will definitely continue my collaboration with her in the future.
