I’m James Walford, founder of Singularity Shift Ltd. I help individuals, founders and teams turn complex product ideas, fragile systems and difficult technical problems into software people can use and trust.

Selected work
I build across the product people touch and the difficult systems underneath it—carrying work through architecture, implementation, testing and real-world delivery.
Product platform
Built and improved a production marketplace platform spanning a React frontend, Rust API, PostgreSQL data and customer-facing email workflows.
Mobile product
Designed and built a non-custodial Android wallet for Move networks, taking the product through real-device delivery and Google Play Early Access.
Desktop software
A cross-platform desktop wallet for the Cedra network, with encrypted storage, DApp integration and an update path designed for real-world releases.
Cryptographic systems
Built proof-oriented infrastructure for signed, portable records that can be verified offline and selectively disclosed when the underlying information should stay private.
Ways I can help
You do not need to arrive with a technical specification. We begin with what needs to change, who it needs to help and what has to be true when the work is done—then choose the smallest system that can deliver it.
Shape and build web, mobile or desktop products from the first useful decision through testing, release and the next sensible phase.
Connect the product, data and operational work behind a business so teams spend less time fighting disconnected tools.
Build for real devices and workflows, with careful attention to performance, failure handling, release delivery and the person using it.
Build Move modules, wallet integrations and proof-oriented infrastructure where correctness, verifiability and clear user experience matter.
Untangle a stalled build, stabilise software that has become difficult to change, or connect systems that were never designed to work together.
A practical toolkit, chosen around the work
How the work moves
Good software begins with a clearer decision, not a longer feature list.
I surface the goals, constraints and risks early, then turn them into an achievable piece of work whose progress and trade-offs you can understand.
Clarify the outcome, the users, the existing system and what is getting in the way.
Reduce uncertainty and make the valuable first phase, risks and trade-offs explicit.
Deliver working progress, test assumptions and explain important decisions as we go.
Launch with the testing, documentation and understanding needed to extend the work.
How projects start
Whether you are an individual with a useful idea or a larger organisation with a difficult system, the starting point depends on the work—not the size of your organisation.
For a focused need
Start with one awkward workflow, useful integration, prototype or contained improvement—scoped to the result you need now.
For a defined workstream
Bring in specialist ownership for a product build, difficult integration, desktop/mobile software or technical rescue alongside your team.
Every engagement is priced individually. After an initial conversation, I will recommend the most sensible next step and set out the proposed scope, assumptions, delivery shape and cost before the build begins. If the unknowns are still too large, we can start with a clearly defined discovery phase.
You pay for the problem we are solving—not a package filled with things you do not need.
Tell me what you need A rough outline is enough. No finished brief or chosen technology required.James Walford · Founder & full-stack developer
I work best in the difficult middle between a promising idea and a dependable product.
My route into software has been hands-on: building, breaking, investigating and rebuilding complete products. It taught me to move from an interface problem to the APIs, data, infrastructure and product decisions behind it—and to recognise when the surrounding design, rather than the immediate symptom, is the real problem.
With Singularity Shift, you work directly with the person scoping the system, making the technical decisions, writing the code, testing the behaviour and explaining the work.
Interface, services, data, infrastructure and delivery treated as one connected product.
Technology chosen for the problem, its constraints and the burden it creates later.
A feature must behave correctly, survive failure and make sense to the people using it.
Clear code, testing and explanation so the work can keep earning its place.
Product partnership
When a project needs broader collaboration, I can work through the Inferenco partnership across AI, mobile and decentralised technology.
A rough outline is enough
Tell me what you are trying to achieve, what is getting in the way and where things stand today. It can be a new idea, an existing system or a problem you cannot yet define technically.
