Hi, my name is Adam Fallon, and I live in London, UK. I am a software engineer, and have a degree in Computer Science.

I like classical literature, going to the cinema and videogames.

Here I mostly write about tech. I dislike large social media sites - as they trample over user privacy, so maintain this website as a way of sharing who I am with the world.

I currently work at Heywa Labs as one of the founding engineers (employee number 2!) - I work on Heywa Search - a search product that answers any question you might have.

You can chat about results, flip through stories that answer your question, and save answers for later.

Before Heywa I was a Principal ML Engineer at Private Equity International, and prior to that I was a Staff Engineer at Trainline I also worked as a Senior iOS Engineer at Rightmove, and an Associate Consultant at Kainos.

• Searching a Data Breach with ElasticSearch – When 500m Facebook records appeared online, I used Elasticsearch to search them.
