I'm an Engineer from New Zealand, now living in Switzerland. I've a little under a decade of experience in product development in the energy industry; most of it relating to grid interactive power electronics applied to a range of applications including electric vehicle fast charging and grid battery energy storage; both with engineering multinational ABB. I now split my time between Ampard, an energy storage startup; and FHNW where I work on producing power with large kites. I've been dabbling in stocks from time to time for the last ten years - early efforts led to burnt fingers, leading to a more cautious approach and positive results in recent years. I greatly admire and respect Warren Buffett and agree with his philosophy that you should buy companies you understand and believe in... but at the same time I'm not blind to the impact of sentiment. Between doing my homework and applying a few analytical tools I've been coding in my spare time I try to make out ok.
