We’re here to make home insurance smarter and more proactive, using tech to bring fresh solutions. We also create digital products that support our customers, always focusing on what really makes an impact. Putting a lot of effort into hiring top-tier professionals is a proof that we care a lot about tech experience, the attitude, human approach, and what we could call „culture fit”. „SwingDev is all about people” - yes, it may sound a bit cliche. But whether we're writing code or just hanging out, we know that people are at the heart of everything we do. We like to have a good time and keep things light, even when we're tackling big projects. We could brag about what’s making us special, but we’ve boiled it down to two key ingredients: mature, companionable people who, rather than compete, prefer to inspire and have each other’s backs; a culture of trust, empathy, and positivity that keeps us together, lets us interact as teammates and friends, and truly enjoy the ride.
