Bio

Part-time introvert, full-time overthinker who somehow ended up teaching machines to teach humans English grammar (yes, the irony isn't lost on me). When I'm not debugging why my AI thinks 'I will had been going' is a valid tense, you'll find me at the go-kart track pretending I'm Alex Albon (fellow Thai representing!), getting roasted by friends for being way too competitive in rental karts while wearing my 'totally necessary' racing gloves, shoes, and helmet that cost more than my monthly GPU budget. I oscillate between wanting to discuss neural networks at parties and hiding in the corner with my headphones on, soundtrack depending on whether it's a race weekend or deadline season. Currently training AI to be a better language teacher than me – which is either brilliant innovation or elaborate career suicide, jury's still out. Will passionately argue that go-karting is the purest form of motorsport while simultaneously explaining why my lap times would definitely improve with just one more piece of professional gear. Send help (or better GPU resources... or honestly, just sponsor my karting dreams at this point).
