Hey there, tech enthusiasts! I've been fascinated by technology since 2000, and that curiosity has fueled my love for learning about new tech. I've had the privilege of being a lead at several big companies, where I've learned a lot about guiding projects from start to finish. What really gets me going is seeing a project come together – being a part of its full journey from ideas to reality. I've always been eager to dive into the latest tech trends, which has helped me lead teams through some exciting projects. I believe in keeping things simple and fun, especially when diving into complex technology. If you're searching for someone who's passionate about learning and leading projects with a down-to-earth approach, let's chat! I'd love to explore how I can contribute to your team's success.
