About Mark
Hi, I'm Mark — a Microsoft specialist with over 20 years of experience delivering enterprise software.
I founded MKLN Sys Consultancy in 2012 following a career in enterprise software development, and have since worked across government, healthcare, insurance, finance and energy — delivering everything from cloud-native Azure platforms and .NET microservices to AWS solutions and IoT analytics tools.
Clients choose MKLN Sys Consultancy for the direct access to senior-level expertise. You'll deal with an experienced engineer throughout — someone who understands both the technical detail and the business context, and who stays focused on outcomes that actually matter.
20+ years in .NET, C# and the Microsoft stack — at enterprise scale
Proven across government, NHS, financial services and insurance
Hands-on Azure and AWS delivery across cloud-native and hybrid architectures
You get senior-level input from day one, through to delivery

We combine deep technical skill with real commercial understanding — so we don't just build what you ask for, we help you build the right thing.

Two decades of .NET, C# and Azure delivery — from architecture through to production and beyond.

We embed with your team, communicate clearly and take ownership of outcomes — not just deliverables.
What We Do
Microsoft .NET & Azure Consultancy Services
End-to-end software consultancy specialising in the Microsoft stack.
From defining your architecture to shipping your product and supporting it in production, we bring the skills, tools and experience to deliver properly — on time and on budget, based in Northern Ireland and supporting organisations across the UK and Ireland with Microsoft Azure and .NET solutions.
Bespoke Software Development
Custom .NET and C# application development tailored to your business processes. We design and build maintainable, scalable software using modern Microsoft technologies — engineered to grow as your business evolves.
Azure Cloud Architecture & Consultancy
Design and implementation of enterprise cloud platforms on Microsoft Azure. From architecture through to delivery, we build scalable, production-ready solutions using App Services, Azure Functions, Service Bus, Cosmos DB and the wider Azure ecosystem.
Design and development of secure, scalable APIs and system integrations using .NET and Azure services. We connect your platforms reliably using REST APIs, messaging patterns and enterprise integration approaches.
DevOps & CI/CD
Azure DevOps and CI/CD pipeline design using GitHub Actions, infrastructure-as-code and automated testing. We help you ship faster, improve reliability and reduce deployment risk across your cloud platforms.
Legacy Modernisation
Modernisation of legacy .NET applications and platforms, including migration to Azure. We reduce technical debt, improve performance and help you transition to scalable, cloud-native architectures.
Our Approach
How we deliver your project
We follow a structured but flexible process that keeps you in control at every stage — from initial discovery right through to live deployment and support.
01
Discovery
We take time to understand your business, your users and your technical landscape before writing a single line of code.
02
Design & Architecture
We design the solution architecture, agree the technology choices and produce a clear roadmap for delivery.
03
Build & Test
Iterative development with regular demos. Automated testing throughout — no surprises at go-live.
04
Deploy & Support
Smooth deployment with full handover documentation. Ongoing support and continuous improvement available.
Industries We Serve
Sector experience that makes the difference
Regulated industries require more than technical skill — they require experience. We have delivered projects across some of the most demanding sectors in the UK and understand the compliance, security and governance requirements that come with them.
Government & Public Sector
Digital services, case management systems and data platforms built to the rigorous standards of central and local government — including GDS principles and security classifications.
Healthcare
Hands-on development and technical leadership on the NHS App — one of the UK's most widely used digital health products — delivering features at scale within a complex, high-stakes NHS environment.
Finance
Software development and technical delivery across wealth management platforms and customer loyalty systems — building reliable, scalable solutions for high-value financial products and their end users.
Insurance
Policy administration, claims management and broker portals. We understand the complexity of insurance products and the high-volume, mission-critical systems that underpin them.
Energy
Development of an IoT platform for industrial-scale battery management — ingesting and processing real-time data from energy storage systems deployed in demanding operational environments.
Your Sector Too
Our engineering principles translate across industries. If you need a reliable Microsoft-stack partner with enterprise experience, we'd love to hear about your challenge.
We let our work speak for itself. Here's what colleagues and clients have said about working with us.
“
Mark is an absolute star — great technically, able to provide thought out solutions, but also a pragmatist, able to adapt solutions to meet organisation requirements. He works great inside a team but is equally adept working on isolated tasks. We leveraged Mark's vast knowledge of Azure within our organisation to great effect. I would 100% recommend Mark and would jump at the chance to work with him again.
Technical Lead
The Openworks Partnership
“
Mark has been a pleasure to work with. His technical knowledge in the .NET stack is both broad and deep, and his knowledge around OAuth, security and authentication in general was instrumental in resolving a number of problems. Mark's attitude and approach to the work has been fantastic — he doesn't just attack the task given but thinks outside the problem and suggests alternative, better solutions.
Software Development Manager
The Openworks Partnership
“
Mark is a pleasure to work with. Not only does he have a high level of skill with C# and a wide variety of .NET technologies, but he also brings an infectious positivity and injects energy into every project. He has a fantastic ability to work to a given specification, but also tries to see the wider picture and always offers options which will improve not only the current project but also the more general development efforts across all teams.
Senior Software Engineer

Was a pleasure to work with Mark over a 6 month period. Helped support our development team on a greenfield IoT project in AWS. Always delivered a high standard of work, on time and was easy to communicate with. All work was done remotely, which didn't pose any issues. Would highly recommend Mark and look forward to working with him further in the future.

I've worked with Mark a few times on a performance improvement project using Azure Functions and Microservice architecture. Mark is extremely talented, knowledgeable and very professional. He has extensive technical knowledge and is highly committed towards his work. Mark maintains calm under pressure, is very approachable and always willing to help team members with technical issues. He has an eye for detail and always strives for the best solution rather than a quick fix.
Microsoft Certified Azure Solutions Architect
KSB Technologies
“
I have worked with Mark for 12 months on multiple high pressure and fast paced Agile projects. Mark is one of the best developers there is — his experience, attitude and knowledge is of the highest standard I have worked with in my career. Mark's ability to work with Product Owners and Business Analysts to ensure he codes to meet business requirements is outstanding. Any team looking to recruit Mark are lucky to have him.

Mark is a strong .NET contractor who can be trusted to deliver quality solutions to complex business requirements. Mark also has a varied technical skill set meaning he can make a big contribution to any size team, working both well on his own and as part of a team.

Having worked with Mark for a year at Davies, I cannot recommend him enough as a .NET developer. He is one of the best developers I have had the pleasure to work with. His understanding of the technology and how to apply it in the real world is exceptional.
Contract Developer

“
I worked with Mark for a client in Kainos. He is hardworking and dedicated to his work, keeps striving for excellence and motivates and helps others to do the same. His willingness to go the extra mile was always appreciated. He has great technical skills, an eye for detail, and a great sense of humour. He is a good team player and a strong contributor — a good professional to work with and highly recommended.
Senior Consultant
Kainos
“
I worked with Mark on a client delivery for over 6 months. His excellent communication skills meant the team were always informed as to the status of Mark's work. Mark worked both independently on development tasks, as well as pairing with team members — in both situations the work produced was of consistently high quality. Mark's experience and pragmatic approach meant he was a very valuable member of the team. I highly recommend him.
