ABOUT BRUNO CHAINA
Seasoned software engineer with more than a decade of hands-on experience across five countries and a wide breadth of sectors. I have successfully implemented adaptable software that behaves predictably, fails gracefully, connects and scales. I self-motivate with a variety of productivity habits and work in a structured, time-boxed way in order to achieve optimal focus. As an energetic individual and excellent communicator, I also enjoy the responsibility of team coaching and leadership. I believe the best way to earn trust is through transparency and delivery of clean, self-tested code within quality, scope and time constraints. Objective I have a preference for contract positions in dynamic companies where I can offer expertise, make use of my skills and design solutions with cutting-edge technology. I wish to be part of a team I can inspire to cooperate, succeed and grow, making a positive impact on the business while working towards the company’s vision and goals. Lately I have been working with the React/.NET/Docker/Kubernetes/Azure stack, although I am proficient in other similar technologies I have used over the years, like Angular, GraphQL or AWS, with a special emphasis on cross-platform development and software architecture design. Interests I regularly trade in the stock market and therefore I frequently follow financial and economic indicators. I have daily exposure to equities, cryptocurrencies, FX and bond products. In my spare time I try to stay fit and healthy by exercising and intermittent-fasting. I enjoy visiting new pubs and exploring new areas, reading about behavioral psychology, anthropology, investments and productivity.
