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.

“Bryan was a great help, figured out the situation quickly, gave me good advice to fix my problem, when he realised there wasn't much more he could do at the moment, he suggested we break until I was able to get access to the service we needed. Highly recommend“

“I’ve been working with Jessamyn for over five years, and she’s absolutely incredible. Early in my career, I didn’t have a senior developer to learn from at my first job — Jessamyn has filled that role for me ever since. Her depth of knowledge and experience is outstanding, and she has a rare ability to explain complex concepts clearly and patiently. She’s not only a brilliant developer but also a truly gifted teacher. I can’t recommend her highly enough.“

“I had an excellent system design session with Dejan today. He broke down the core principles of approaching system design interviews in a way that clicked for me. We discussed how to structure answers under time pressure, what common pitfalls to avoid, and how to prioritize clarity over complexity. Dejan also helped me identify which areas I should focus on next. We even dug into how one might architect something like YouTube, which made the concepts feel much more real and applicable. He’s clearly deeply knowledgeable, but just as importantly, he knows how to explain things in a digestible and actionable way. Highly recommended if you’re serious about leveling up your system design skills.“
