Hi! This isn't a portfolio where I try to impress you with exaggerated claims; it's just a personal website I built on a weekend @ a cafe in NYC.And warning: this sounds a bit like an article, not a website. Click on the Add to heck yeah list[1] button to get in touch.
Get to know me...
I have been writing for software developers for over 4 years as a technical writer
Statistically speaking, at least 1 in every 8,100 people[2] on Earth has read my words somewhere on the internet.
In the meantime, I have worn different hats. Because when you're a technical writer, it isn't all about writing— you are also a developer who writes code, builds software and works with all other things you're writing about. How else can you write content that's supposed to connect with other developers?
Talking about work, I have been writing for big companies since the pre-ChatGPT era for big money but not anymore. I write, yes, but not for big companies or big money. I'm writing for small companies with cool people instead. My dream companies now are companies with < 50 team members, with no ego.That’s also why I connect so well with startups. I love helping small teams with content, a field some founders ignore; Of course, content can't fix or help in insane growth for SaaS start-ups. but it can make them stand out in the crowd!Read my guide to "content for start-ups" for more
