I am currently a Senior Analyst at JLL. I joined the team as cross-platform software specialist and have architected and worked on a couple of applications in React and React Native, utilizing GraphQL to provide a universal endpoint for most of the company's data sources. To date, I have worked on a lot of interesting and bleeding edge solutions in the PropTech market including (but not limited to) a distributed application (DApp) in the Ethereum platform.

As a software generalist, I am always on the prowl to improve my development toolbox. I enjoy learning new tech so I can evaluate if they can solve existing problems better. If you are going to ask me what my specialization is, it will be software design, software architecture and project solutioning.

In my free time, I enjoy hiking jungles and taking photos or writing at my tech blog. I am also an avid angler and goes on boat fishing trips quite frequently.
