ABOUT ME

Hi, I’m Togy Thomas.

I’m a Solutions Architect who has designed end-to-end solutions for large organisations, including HM Revenue & Customs, the Ministry of Defence, Cambridge University Press & Assessments, and British American Tobacco.

My expertise spans application, integration, platform, and security architecture in multi-cloud environments.

I prefer to work with my clients on demand, giving you the support you need—when you need it.

Connect with me on LinkedIn or message me directly on WhatsApp: +44 7852 903786. I am based in the UK.

what do i offer?

With over 20 years of experience in architecting technology systems, I offer:

Cloud-Native Solution Design

Accelerate innovation with secure, scalable, and resilient cloud-native platforms. By leveraging microservices, event-driven architectures, containerized deployments, and serverless computing, I enable faster time-to-market, seamless integrations, and cost-optimised operations.

Designs for Cloud Migration

Plan and execute secure, seamless migrations from on-premises solutions to AWS, Azure, or GCP. I design scalable target architectures, ensure smooth data and application transitions, and minimise risk and downtime - unlocking agility, cost efficiency, and cloud-enabled innovation.

High Quality Design Artefacts

Clear, comprehensive design artefacts for complex solutions across any cloud platform. My HLDs and LLDs align with industry standards, best practices, and well-architected frameworks, incorporating proven patterns and well-defined interfaces - removing ambiguity so delivery teams can execute with confidence, speed, and precision.

Coaching & mentoring

Hands-on coaching for junior architects and engineers; elevating teams while solving today’s problems.

Secure by Design Architecture

Embed security from the very beginning of every solution. I apply Secure by Design principles to ensure architectures are resilient against threats, compliant with industry standards, and aligned with well-architected frameworks. By addressing security concerns proactively, I reduce risks, simplify compliance, and enable faster, safer delivery.

The on-demand model

By engaging with me on an on-demand basis, you gain:

Outcome based delivery

Agreed outcomes are delivered through well-defined work packages.

Avoid ramp-up delays and hiring costs

Start delivering short-term outcomes quickly, without long lead times or recruitment overhead.

Seamless Onboarding

Engage through your existing contractor procurement methods. No need to modify your standard contractor agreement.

Exceptional Value

You only pay for agreed work packages — with no idle resource costs. There’s no cost to set up the contract, but you’ll have an experienced architect on standby whenever the need arises.

how does it work?

Step 1: Seamless onboarding

I onboard through your existing contractor procurement process and standard agreements, using an agreed day rate.

Step 2: Define the work

We discuss your specific requirement and agree on the desired outcomes and effort — based on that, I define a work package.

Step 3: Delivery and invoicing

I deliver the agreed work package. I invoice only for the agreed effort.

Step 4: Flexible re-engagement

The contract remains in place with no ongoing costs. Re-engage me anytime a new need arises.

FREquently asked questions

Can you work through our existing procurement frameworks?
Yes. My services can be onboarded using your organisation’s existing contractor engagement model and preferred suppliers — whether you're based in the UK or internationally. No changes to your current onboarding process are required.
Do we need to change our standard contractor agreement terms and conditions?
No changes are needed — I’m happy to work under your organisation’s standard contractor agreement.

The only practical difference is that I invoice only for the time agreed and spent on an approved work package, rather than billing eight hours each day of the month by default.If you’d prefer to reflect this in the contract wording, that’s absolutely fine — but from my side, it’s not required. My focus is on keeping things simple, transparent, and aligned with how you already engage contractors.
For a client in the UK, can you work inside IR35 if required?
Yes. I can work through an umbrella company if your organisation requires it, and I’m familiar with the compliance and reporting standards involved.
What kind of architecture work do you deliver as fixed-cost packages?
I focus on short-term, well-scoped pieces of architecture work—such as solution design, design documentation, architecture reviews, technical options analysis, or assisting with RFI/RFP responses. Each package is tailored to your specific need and agreed upfront in terms of scope, effort, and outcome. Explore the full range of examples in the Services page.
What if the scope changes or isn’t fully clear at the start?
That’s absolutely fine. We start with a brief discussion to clarify your goals and constraints. If things shift midstream, we can adjust the scope or timebox the work until priorities are clearer. I aim to stay flexible, while still providing predictability.
How quickly can you get started?
After a contract is established, I'm able to commence work on a package as soon as it's required.
Do you work remotely, or can you attend meetings onsite?
I work primarily remotely, which keeps engagements efficient and cost-effective. However, I’m happy to attend onsite meetings when needed—such as stakeholder workshops, onboarding sessions, or key design reviews.
Can I reserve your time on a monthly basis?
Yes—if you expect to need support regularly, I offer an optional retainer model where you can reserve a minimum of 5 or 10 days per month. This gives you prioritised access to my time over other clients and ensures I’m available when you need me, without delay.
