    I am a fullstack developer based in Nairobi, Kenya. I mainly use Python (Django, FastAPI, Flask) and Typescript (Express.JS, React) to develop both the frontends and backends of web applications and APIs. I also mainly use PostgreSQL as the go-to relational database. I use MongoDB when I need a NoSQL database. I can work with other databases too (MySQL, Redis) if a project has a hard requirement for these. I can tackle DevOps tasks too. These include deploying apps to bare-bones Linux servers, Kubernetes clusters or third party providers such as GCE and AWS. I can also set up CI/CD pipelines on Github (Github Actions) and Gitlab. I am an excellent communicator and speak fluent English. I am also well-organized and efficient.

    Dear Client, Picture yourself reading a newspaper or an online article on a topic that you're entirely green in. You'd expect that the writer is simple enough to enable you to comprehend their writing. In addition to this, you expect to find the article well detailed to equip you with the necessary information. After all, this is why you're reading on that particular topic, to gain knowledge. This is before mentioning the quality and creativity of the article, which should be summed in one word, exemplary. This is a simple analogy of what content writers are supposed to do. To inform their audience by providing well-researched articles explained in all simplicity. Their articles should embody all this creatively and, in some instances, add some humor. However, this is not the case with many writers because the need to earn an extra buck is greater than satisfying a client. According to a survey conducted by Chartbeat, 45% of readers will leave your article after a mere 15 seconds. 60% of them will never return. All this shows us that content writing isn't just about churning out content in grammatically correct sentences. More goes into it, with attention focused on providing quality work, creative content, and writing passionately consistently, all of which I can provide for you. The aim is always to inform your audience and give them a reason to return time and again. When it comes to creative content writing, you're looking for a writer that can capture your audience for more than 15 seconds and turn them into a regular reader. This is what I'll endeavor to do time and again if hired. With my exemplary writing skills and passion for the same, I can provide you with quality articles to keep your audience informed and glued to your site. I have gained experience in writing over the last four years. I have learned the intricacies of using words to communicate effectively in different niches. From online articles and writing on the medical niche to writing about programming tutorials, the principles of good writing seldom change. Perhaps I should also mention that I'm fluent in Python, Javascript, CSS, HTML, Flask, and Django. Lastly, you won't have to worry about deadlines as I'll strive to do my work on time. What are you waiting for? Hire me today, and let's take your brand to greater heights. Talk soon Ken Nzioka
