Case Studies
TotallyMoney’s mission is to improve the UK’s credit score and cement its position as one of the most customer-focused FinTech brands nationwide.
I helped their teams gain confidence with serverless technologies such as API Gateway, Lambda and DynamoDB. They discovered new architectural patterns and made strides towards refactoring their existing services to serverless.
InDebted’s mission is to fix the broken debt collection industry.
I helped the team get up to speed with serverless and become comfortable with new services such as DynamoDB, Kinesis and Step Functions. They have since rebuilt and modernised their entire platform and are making heavy use of open source tools such as the Serverless Framework and Terraform.
ElderCounsel helps legal practitioners streamline their elder law practices. Their flagship product is a document drafting software that can generate a wide array of legal documents related to elder law.
I designed and implemented the backend system on AWS. The system has many integrations with 3rd party systems such as SalesForce and specialized CRMs that cater to law practices.
We were able to overall many challenges and deliver a working system on time and on budget.
Nova Sport is a social network that lets students connect and play sports together and gain access to their university’s sports classes. As a bootstrapped startup, Nova Sport had a limited budget to build and launch their initial MVP.
I worked with the founders to fine-tune requirements, and I designed and implemented the backend for both the mobile app and CMS in 4 weeks.
The MVP launched on time and without a hitch. It impressed the investors, and the app was well-received by users. This allowed the company to raise further funding and continue to grow.

Let’s schedule a call to talk about your project and how I might be able to add value to your business.
Why you shouldn't hire me
If you’re looking for the cheapest option, I’m probably not the right choice. My services come at a premium because I specialize in solving complex problems quickly and effectively. Hiring me isn’t just about cost—it’s about the value of getting it done right the first time and avoiding expensive mistakes down the road.
If you want someone to blindly execute without questioning your approach, we’re unlikely to be a good fit. My role is to challenge assumptions, explore alternatives, and guide you toward solutions that are scalable, reliable, and future-proof—even if that means saying “no” to less optimal ideas.
If you’re expecting a quick fix or shortcut, I might disappoint you. I focus on long-term success, which means addressing root causes, not just symptoms. This requires thoughtful planning and collaboration, but it saves time and headaches in the end.
Finally, if you don’t have clear goals or a definition of success, I might not meet your needs. I work best with teams ready to set objectives, measure progress, and adapt to ensure real results.
