DirectorXmpp Standards Foundation Nov 2024 - PresentEverywhere Open Standard Messaging Is NeededThis is an elected voluntary position running the Foundation, which is principally a Standards Development Organisation focused on maintaining and developing XMPP, the leading open standard instant messaging protocol.I'm focusing on ensuring that process documentation is accurate, and also making the tea. -
Principal ConsultantExtensible Messaging Ltd Aug 2024 - PresentIn A Corner Of A Field In CamarthenshireStrategic and Project specific software engineering, including quite a lot of XMPP-related projects, as well as operational engineering.I'm usually quite busy, but if you need an expert in XMPP with experience of military/government/healthcare, or indeed a dab hand at monitoring and performance tracing, give me a shout.

Random Acts Of GeniusFreelance Oct 2023 - Aug 2024Within The InterwebsDoing strategic engineering on a very reasonable day rate, so I can be picky about the next role.I went straight into work directly after leaving Peppy, with multiple previous employers asking about availability. They're all great companies, but I'm looking for a permanent place for the long term, doing something new. Like my previous places, I want to work with a team that's professional and generous. And as before, I want to work on things that are meaningful, interesting, and challenging.If you think that's sounding like you, and you're looking to hire someone versatile, focused on backend work (I can't do the pretty stuff), but with an eye across the whole technical estate, then my DMs are open (and not just because I don't know the settings).

Staff EngineerPeppy Jan 2023 - Oct 2023A Corner Of A Field In West WalesNobody tell them, but I'm still writing code.As Staff Engineer, poked my nose into much more at a high level, though often not as deep. However I have personally:* Designed, implemented, and deployed a fine-grained onboarding eligibility check for our users.* Redesigned, implemented, and then redesigned again, filtering for our content.* Implemented session recording in our internal web app.* Designed and implemented heuristic detection for InfoSec policy infractions to aid in compliance evidence.* Still quite funny on Slack. -
Senior Software EngineerPeppy Jan 2022 - Jan 2023A Corner Of A Field In West WalesTurning copious mugs of tea into clear and maintainable code, providing a stable and reliable service.During this period:* Designed and lead implementation of our migration from a UK-only single-tier system into a multi-national, multi-regional, multi-tiered service. This involved balancing regulatory requirements with business needs, delivering to shifting deadlines and agile requirements. All with virtually no downtime.* Redesigned security entirely on a running system from trivial roles to a full hybrid authorization system, based on clearances/labels generated using ABAC-style bespoke code, without any downtime.* Implemented performance telemetry and error reporting via Sentry across most of the estate (and encouraged the mobile team into doing the same).* Devised alerting and monitoring to flag problem for Engineering, InfoSec, and Customer Success.* Quite funny on Slack.

Senior Software EngineerPando May 2019 - May 2021London, United KingdomPossibly slightly too excited to work at Pando (previously Forward Health) as "That Guy Who Knows Messaging", where I join an excellent team working to make clinical messaging in the NHS and beyond more intelligent, more secure, and just all-round better. Great fun to work in an industry I can actually talk about, too, so feel free to ask more!During my time here our clinical messaging product was used extensively by those in the NHS and DMS, including many in the front-line of the pandemic. During one month alone, this drove usage growth in excess of 700%, and I helped our team scale the service by working on efficiency at the SQL, API, and even the Mobile App UX. By the time we were exiting the initial phase of the pandemic, the service used less resource than on entry, supported several times the numbers of users, and had significantly less downtime than many other common messaging tools. New feature development pace did not slow down. -

DeveloperFelspar Ltd 1999 - 2001Fleps, as it was affectionately known, was a company providing billing systems to telcos, enterprise intranet portals to banks, and all manner of information management systems to all manner of customers - a couple of which went bust at the wrong moment, effectively killing the company.As a senior developer, I worked on both the JScript/ASP frontend systems and the C++ backend systems, on the lower level object database and the high-level presentation layer.
