Hi, my name is
Pawel Lisowski.
I build things for the web.
I build scalable full-stack web applications. With 8+ years across enterprise teams in pharma, aviation, and financial services, I focus on fast, reliable systems that hold up in production. Currently at Novartis.
About Me
I'm a Senior Software Engineer who enjoys building things that live on the web. I've been learning programming since I was 14, and after graduating from university in Waterford, Ireland in 2016, I started my career at Fenergo in Dublin as a Software Engineer in Test, which quickly turned into full-stack development.
In 2017 I moved to Gdynia, Poland to pursue more interesting projects as a software engineer. Since then I've worked with organizations like Novartis, British Council, Lufthansa Systems, and clients including Boeing, Danfoss, and Signal Ocean. These days I mostly build executive dashboards and data pipelines that turn messy data into real-time insights people can actually act on.
Outside of client work, I'm building Lisovate, a solo studio making products that put generative AI and autonomous agents to work in developer and software team workflows. Beyond writing code, I enjoy exploring product ideas, occasionally unwinding with video games, and touching grass whenever possible.
Here are some technologies I've been working with:
