From zero to scale

I'm Tadas Pilionis, a Data Engineering Tech Lead specializing in building scalable infrastructure from scratch — and making sure it stays performant as you grow.

Currently leading the data team at Modash, where I built the initial infrastructure from zero and now oversee pipelines processing massive volumes of unstructured data. Previously led Data Engineering at BITĖ, modernizing their entire analytics stack.

I also mentor the next generation of data engineers as a Senior Team Lead at Turing College.
