Python Backend & DevOps Engineer · Co-CTO at Iskra
I build async Python backends and run the infrastructure underneath them.
Ten years across API architecture, Kubernetes operations and open source in the Plone and Guillotina ecosystem. Based in Manresa, Barcelona.
As of November 2026: GitHub pull requests, PyPI profile.
Open source contributions to Guillotina, the AsyncIO data API framework from the Plone community, and its ecosystem.
Upgraded guillotina_elasticsearch and guillotina_audit to Elasticsearch 8 and 9. Prepared guillotina_gcloudstorage for Guillotina 7 and Python 3.10+, replacing oauth2client credentials with google-auth.

Records the object, timestamp and action for each create, update and delete in Guillotina, and indexes the events in Elasticsearch for search. Includes a query parser and an audit-migrate command.
Added a low-level Model Context Protocol contrib package, with tools and tests, to Guillotina core. Built guillotina_nuclia, which provides chat with persisted history, streamed answers, retrieval responses and stateless chat.

Fixed content duplication for cloud file fields, where the copy shared metadata references with the source and could return 404s. Duplicates now receive their own copy of the blob.
