Open for enterprise and government engagements
Independent engineering for government, healthcare and enterprise systems — twelve of them, nine written up in full on this site.
Work delivered across Saudi Arabia, Egypt, the United Kingdom and the wider Gulf, for government, healthcare and enterprise. Nothing claimed on this page is something you cannot go and check.
Track record
Every figure below is countable from the case studies on this site.
Background
Enterprise systems since 2013, delivered independently alongside a Senior Technical Lead role at _VOIS (Vodafone Intelligent Solutions).
The salaried role is Senior Technical Lead at _VOIS (Vodafone Intelligent Solutions). Alongside it sit the twelve systems in this portfolio: two government portals in Saudi Arabia, medical education and clinic systems in the United Kingdom and across Europe, a teacher app, a news platform and an online store, and an ERP, a financial platform and an integration gateway across the Gulf. Nine of them are written up in full.
Every write-up records the same things: the sector, the region, how long it ran and how many people were on it. They range from five months to sixteen, and from solo delivery to a lead with four engineers.
Municipal service platforms, citizen portals, and administrative systems for Saudi government entities.
Medical examination platforms, clinic management solutions, and patient portals serving healthcare providers.
Resource planning, financial management, and integration platforms for multi-department organizations.
Student management systems, e-learning platforms, and educational administration tools.
Selected work
Three of the twelve carry both a public address and a full write-up — open the system on one side, read the engagement and the architecture on the other.
Large-scale Moodle-based e-learning platform preparing doctors for the MRCOG postgraduate qualification from the Royal College of Obstetricians and Gynaecologists
Large-scale Moodle-based educational platform for MRCOG exam preparation. Serving thousands of doctors across Europe preparing for the Royal College of Obstetricians and Gynaecologists qualification.
Healthcare · International (UK-based certification)
Medical examination platform for Royal College of Surgeons fellowship candidates. Automated assessment and progress analytics.
Government · Hail, Saudi Arabia
Digital government platform for Hail Municipality, Saudi Arabia. Citizen services and municipal operations.
How the systems are built
Six positions, each one taken on a project you can read about here.
Public-sector and healthcare work starts with residency and audit, not with a framework. The Hail platform runs on cloud infrastructure inside Saudi Arabia and logs access for government review because that was a requirement of the brief, not a hardening pass afterwards.
Documentation and knowledge transfer are written while the system is being built, so your team can run and extend it without me. Decisions are explained in language the people who have to live with them can act on.
Most of this work begins with systems nobody can switch off. The municipal platform reached its legacy data through an adapter layer with standardised interfaces, so the old system kept serving while the new one took the load.
The EMRCOG platform is busiest on the days an exam board opens registration. Capacity follows that calendar in advance rather than reacting to it, because the peak was known before it arrived.
The Hail platform was split into modular services and a configurable approval engine specifically so the next department could be added without reopening the rest of the system.
A citizen portal is used by people with very different levels of technical confidence; a study platform by clinicians working through it in whatever fragments of time they have. Both were tested with those users and simplified until the common task was short.
Judgement
Four problems these systems ran into, and what was done about each one.
Medical EducationEurope-wide (UK-based, serving international medical professionals)
The constraint
What was done
Implemented auto-scaling infrastructure with predictive scaling based on exam calendars, plus aggressive caching layers

What was done
Implemented question randomization, strict time limits, browser lockdown features, and activity monitoring

What was done
Security architecture aligned with NCSC guidelines and regular penetration testing
Working together
Five stages, with what you are holding at the end of each one.
What exists, who uses it and what it has to comply with — before any code. On the municipal work that meant reading the systems that could not be switched off; on the citizen portal it meant sitting with residents while they tried to use it.
You receiveA written problem statement, the real constraints, and a scope you are able to say no to.
The decisions that are expensive to reverse get made and written down first: where the data lives, how the system is split, what the audit trail records, which parts have to keep working when one of them fails.
You receiveAn architecture note and the key decisions behind it, in language a non-engineer can review.
Small teams and honest reporting. Across the engagements written up here the team was anywhere between one person and a lead with four engineers, and the work ran between five and sixteen months. You are told when something slips, at the point it slips.
You receiveWorking software you can use on a staging environment, matching the scope that was agreed.
Going live is a milestone, not the end of the work. Monitoring, backups and the recovery procedure are in place and tested before launch rather than assembled during the first incident.
You receiveA running system with monitoring, backups and a recovery path that has actually been rehearsed.
Documentation and training so your team can run the system, and a support arrangement for the times it still needs me. Two of these platforms have stayed under continuing development since their first release.
You receiveDocumentation, a team that has been walked through it, and a named route to reach me.
Scope
Four kinds of engagement: building the system, designing the architecture, reviewing a decision somebody else has to make, or leading the team that does the work.
End-to-end development of enterprise applications.
Strategic technical planning and architecture design.
Expert guidance on technology decisions.
Hands-on technical leadership for development teams.
Writing
Forty-seven articles across ten subjects, from software architecture to security engineering — the reasoning behind the work, in public.
Software Architecture18 min read
A practitioner's guide to implementing event-driven architecture at scale. Covers message broker selection, event schema design, eventual consistency patterns, and lessons from production systems.
Frontend Engineering17 min read
Optimize React performance with useMemo, useCallback, and code splitting. Real performance metrics and patterns from large-scale production applications.
Security Engineering21 min read
Implement secure JWT authentication with refresh token rotation, RBAC, and OAuth 2.0 flows. Production patterns from healthcare and government systems.
Fit
Worth knowing before you write. Being told no early is cheaper for both of us.
Next step
The more specific you are about the constraint, the more useful the first reply will be.
Write what the system has to do, what it has to comply with, and when it has to exist. You will get a reply within a few business days — either an honest read on the problem, or a clear no if this is not the right fit.
