Building products that work and last

About

I'm Alex Filatov, a software engineer and founder based in London. I started building products long before startups were cool and I'm still obsessed with creating things that work and last. I joined Syft in 2017 as one of its first engineers, contributed to about 20% of the codebase and helped scale the platform through its acquisition by Indeed in 2019, where I later led the Flex Levels feature as a senior software engineer.

Alongside that I bootstrapped SHOPYBOT, a chatbot platform for online stores built on an Elixir and Phoenix backend that grew to over 1,300 customers, and co-founded CXRATE, one of the top currency exchange rate platforms in Ukraine, which won $60,000 from the Facebook FbStart program.

Since August 2025 I run Gymbile, an all-in-one platform connecting personal trainers with clients worldwide: live interactive sessions, flexible payments and client management tools. Most of what I build runs on Elixir, Phoenix and OTP, with AWS and Kubernetes underneath and TypeScript, React and PostgreSQL where they fit. I also maintain open-source Elixir libraries, including a LiveKit SDK, a BORSH serializer and a NEAR API client.
