Reliably Coded

Reliably Coded B.V. is the personal company of Sasha Romijn from Amsterdam, The Netherlands.

I’m an independent developer, consultant, and community organiser with over 15 years of experience delivering high-quality software. I help clients turn complex needs into robust, maintainable systems, both through hands-on implementation and broader strategic advice.

In recent years, my focus has been on internet infrastructure, internet standards, and network management. I’m the author and maintainer of IRRD, which powers the IRR registries of ARIN, LACNIC, LEVEL3, NTTCOM, RADB, IDNIC, TC, and partially APNIC. I’m currently working on NRTMv4, a new standard for reliable IRR data mirroring, and serve as co-chair of the RIPE Open Source Working Group. Many network operators across the internet directly or indirectly rely on my work.

Most of my work is open source, and I take pride in creating systems that are reliable, clean, and built to last. I specialise in Python and Django.

I regularly speak at internet infrastructure and developer community events. I’m also passionate about inclusive communities and technical events, and am actively involved in conference organising and community management for Write the Docs. I’ve previously been a committer and conference organiser for the Django web framework.

Current roles

• Author and maintainer of IRRD, the routing registry daemon powering major IRR registries worldwide.
• Currently working on draft-ietf-grow-nrtm-v4, a new protocol for reliable IRR mirroring.
• Lead developer of Internet.nl, a testing tool for internet standards compliance.
• Core operations team and conference chair at Write the Docs.
• Developer and maintainer of IRRexplorer.
• Co-chair of the RIPE Open Source Working Group.

In the past I’ve done various work for IETF, ISOC, and was a committer on the Django web framework.

Side projects

• Running AS213279, a small personal network to experiment with BGP, OSPF, RPKI and other internet technologies. This website is hosted on it — if you’re reading this, it works.
• Co-founder of the Internet Resiliency Club: a community project exploring decentralised, infrastructure-independent communication technology. We experiment with LoRa mesh networking, but our main interest is community building and wider technology exploration.
• The Less Obvious Conference Checklist: a checklist of less obvious things for conference organisers that help build amazing, welcoming, and inclusive events.
• Open-Source Happiness Packets: a platform for anonymously reaching out to people you appreciate in your open-source community. Built with Mikey Ariel to promote kindness in the Django and wider open-source communities. Over 1250 messages sent, with more than 125 publicly archived.
