What I'm looking for

I'm looking for an individual contributor role focused on building features, solving production problems, and improving an existing product.

At Pigu.lt, I build and maintain PHP services and storefront features for an e-commerce platform across Lithuania, Latvia, Estonia, and Finland. I work across a Symfony API and a long-lived CodeIgniter application.

I’ve developed Elasticsearch and Algolia search integrations, including multilingual analyzers, relevance rules, and search suggestions. I also implemented AI-assisted search reranking and product replacement recommendations, validating model responses against available candidates.

My work at Pigu.lt also includes checkout and payment changes, production troubleshooting, and regression coverage. Earlier, I developed CakePHP applications and REST APIs at Ivėjas, and built and published Android and iOS games as an independent game developer.
