Systems businesses rely on.
Trusted for years.

Long-running systems in regulated, high-volume and enterprise environments, with our technical director hands-on in every one.

Fintech · Wealth management

One back office. Every system connected.

A regulated UK wealth manager with billions of pounds in client assets runs its operation on a licensed back-office platform we have led since 2017, delivered with Line of Business Solutions Ltd. We have connected it to the firm's third-party applications, including systems built by IBM, so client, portfolio and operational data move without rekeying. Nine years, one technical lead, working directly with the firm's own team.

E-commerce · Integration

E-commerce and back office, one operation.

For a national retailer with tens of millions of pounds in annual sales, we led the integration of its e-commerce platform with the same back-office platform, delivered with Line of Business Solutions Ltd, so order and operational data flow between the two without manual handling.

E-learning · Enterprise

E-learning for global enterprises.

Before founding the company, our technical director spent five years at Digits, an e-learning solutions provider, as developer and then architect. He delivered an award-winning learning management platform and bespoke training systems for global asset managers, a UK private bank, a global security services company, and household names in consumer goods and automotive, and led security testing with independent penetration testers.

Booking · Payments · AI

Platforms we build and run ourselves.

We also design, build and operate our own booking and payments platforms: ticketing, memberships, door check-in, Stripe Connect payments and invoicing, plus AI features built on OpenAI that generate event listings and images. We take the support calls too. That is how we know what a system costs after launch.

Client names and references are available on request, under the same confidentiality we extend to every client.

Regulated wealth management, high-volume e-commerce and enterprise platforms. The kind of systems where downtime is costly and mistakes are expensive.

Integration first.
Then everything around it.

Systems and API integration is our specialism, across fintech, e-commerce, booking and e-learning. We take on work where a business needs someone accountable for the whole solution, not just the code.

Systems & API integration

One joined-up operation instead of a dozen disconnected tools. We design, build and support the APIs and connections between your core platform and your CRM, payments, data feeds and third-party systems, including the ones built by large vendors. That now includes AI integration: connecting models such as OpenAI to your data and workflows, securely and with an audit trail.

Bespoke software and back office

Tailored software for the system you cannot run without, kept reliable and moving forward. Long-term ownership of licensed and bespoke platforms: new capability, performance, security, and the discipline of serving many clients from one codebase.

Cloud platforms, end to end

From idea to a live product taking payments, built and hosted on AWS, Azure and Supabase. We have launched and operate our own, so we deliver the whole thing and we know what it costs to run afterwards.

Brand and design

Logo concepts, brand identities and design systems for corporate and public-sector organisations. The same team designs the interfaces of the software we build, so your brand carries through from the logo to the product.

Ways to work together.

Start small, bring us in to lead the team you already have, or hand us the whole build.

Option 1

Discovery

A one to two week, fixed-fee review of your requirements, systems or existing codebase. It ends in a written solution outline, a risk assessment and an estimate, so you can decide with the facts in front of you.

Option 2 · Lead your existing team

Technical leadership for your development team

Already working with an in-house or outsourced development team? We take technical ownership of the project and lead the team you have. You keep the cost advantage of your developers and gain a senior lead who is accountable for quality and delivery.

  • Architecture, technical standards and sprint planning
  • Independent code and security reviews
  • QA and release management on every release
  • Clear weekly progress reports in plain English
  • One accountable point of contact between you and the developers

Option 3

Full delivery

We design, build and run it end to end with our own team, from discovery and architecture to a live system and long-term support.

Built to be trusted with the systems that matter.

One accountable lead.

Our technical director owns your engagement from requirements to delivery to support. No account managers between you and the decisions.

Senior attention on every engagement.

We take on a limited number of clients at a time, so every engagement gets senior attention from start to finish. Design and engineering are brought in to match the project, led by the same person throughout. No juniors learning on your project.

Built to be owned.

You own the code. Everything is documented and handed over so it can be supported without us if you ever choose.

Tested and secure as standard.

Dedicated QA on every release, penetration-tested systems, and a decade in regulated fintech and financial services, where mistakes are expensive.

Start small, decide with evidence.

Most engagements begin with a short, fixed-fee discovery that ends in a written solution outline and estimate. You decide on the real work with the facts in front of you.

Remote, on UK hours.

We have delivered remotely for UK clients since 2016, working UK business hours, with regular check-ins and a single point of contact.

Founder

Elijah Tella

Founder & Technical Director

Elijah has been shipping commercial software since 2008, when his first contract, a pharmacy management system for Ofred Pharmaceuticals, was taken to market and distributed to pharmacists. He spent five years as developer and then architect at Digits, an e-learning solutions provider, followed by senior engineering roles in telecoms integration and cruise travel booking, and founded Evision Technologies in 2016.

His experience spans fintech, e-commerce, booking and e-learning. Since 2017 he has been technical lead on the back-office platform a regulated UK wealth manager runs on, accountable for its API integrations with third-party financial systems, including those built by IBM, and working directly with the firm's own team.

Alongside client work he leads the company's in-house platforms, from design through to live operation. He leads a small, consistent team covering engineering, quality assurance, design and operations, sets the architecture, and stays close enough to the work to be accountable for it.
