Software Engineering

UX and autonomous quality engineering

Interfaces people can use, and releases you can trust

Where products lose users and releases lose confidence

People judge software by whether they can finish their task. When the screens follow the system instead of the work, users make mistakes, call support or give up.

Manual regression testing slows every release and still misses defects, and testing only at the end turns small problems into late, expensive ones. Peak traffic then finds the limits nobody tested.

What changes for you

  1. Products people finish their tasks in

    Flows designed from research and tested with real users before the build, for every language and screen size you need.

  2. Accessibility designed in

    Designs and code built to WCAG 2.2 AA and to national accessibility rules, checked on every release.

  3. Releases without surprises

    Automated suites and quality gates that stop a broken release, and load and chaos tests that show how the system fails before your customers do.

What we deliver

  • UX research and information architecture

    Interviews, observation and analytics turned into clear findings, and a structure for navigation, naming and content.

  • Wireframes and tested prototypes

    Each key task mapped step by step, including errors and empty states, and clickable prototypes tested with real users.

  • UI design systems

    Design tokens, components and usage guidance kept in step between Figma and code, so every product stays consistent.

  • Accessibility compliance

    Designs and builds checked against WCAG 2.2 AA for contrast, focus order, target size and screen-reader labels, including right-to-left layouts for Arabic.

  • AI-driven self-healing QA

    Automated regression and integration suites run on every change. When the interface moves, AI-assisted tests propose the repair for an engineer to approve, instead of failing at random.

  • Performance, load and chaos testing

    Load and stress tests of the critical journeys, and controlled failures of services and networks that show how the system degrades and recovers.

  • Quality gates and reporting

    Tests, coverage and security scans that stop a release when they fail, with defect trends and release readiness in one place.

How we work

  1. Research and assess

    We interview users, review analytics, support requests and recent defects, and find where problems escape today.

  2. Define

    We agree the users to design for, the risks to test and how success will be measured.

  3. Design and test with users

    We prototype the key flows, test them with real users and fix what confuses them before the build.

  4. Automate

    We build the test suites and test data, and wire them into your pipeline as quality gates.

  5. Load and break

    We load the system to its peak and beyond, inject failures, and fix what gives way before launch.

  6. Keep it healthy

    We review what ships against the design, fix unstable tests quickly and train your team to own the suites.

Technologies and standards

We use the tools that fit your stack and keep tests in your repository. Naming a product does not mean a partnership with its vendor.

How to start

A design or testing engagement can start on its own or as part of a build. Specialists can also join your team as embedded designers or QA engineers.

What happens next

  1. Pre-consulting session

    A free 30-minute online pre-consulting session: we go through your goals, systems and constraints.

  2. Readiness review

    In a free 48-hour readiness review, a Principal Architect checks your project against the 6-point Definition of Ready and recommends the track that fits.

  3. Choosing the track

    Scope-ready projects receive a binding proposal within 3–5 business days. Concept-stage projects start in the Blueprint Studio. A live system that is failing, undocumented or needs integration starts with a diagnostic of 1–2 weeks. The Blueprint Studio and the diagnostic each have a fixed fee, quoted in the proposal.

  4. Delivery in five stages

    Mobilisation, sprints with live demonstrations, integration and hardening, acceptance and go-live, then managed services. After launch comes a warranty period, then optional support and maintenance.

  • Embedded specialists and strategic augmentation

    Nearshore and on-site principal engineers and specialists, and embedded solution, transformation, PQC and integration architects.

  • AI-native product teams

    Managed, cross-functional pods of senior engineers, equipped with agentic coding and QA harnesses.

Questions and answers

Do we need user research if we already know our users?

You know a great deal, and research builds on it. It tests assumptions with the people who do the work, and often reveals steps, workarounds and terms that never reach a requirements document. A small round of interviews and prototype tests costs less than changing software after it ships.

How do you make products accessible?

We design to WCAG 2.2 AA from the first wireframe: enough contrast, visible focus, a logical reading order, large enough targets and a label for every control. Automated checks run on every change. Before each release, we test key journeys by hand with a keyboard and screen readers.

Can you design for Arabic and other right-to-left languages?

Yes. Right-to-left design is more than flipping the screen: navigation, progress indicators and directional icons mirror, while numbers, logos and media controls usually do not. Arabic text needs its own typeface, size and line height, and we review both directions with native readers.

What is self-healing test automation?

Interface tests usually break when a button moves or is renamed, even though the feature still works. Self-healing tests use AI to find the element again and propose an updated test, which an engineer reviews before it is accepted. The suite stays reliable without hiding real defects.

Should we automate all our tests?

No. Automate what runs often and must give the same answer every time: unit tests, API tests and the journeys that matter most. Keep people for exploratory testing, usability and features that are still changing. A smaller suite that never fails at random is worth more than a large one nobody trusts.

What is chaos testing, and is it safe?

Chaos testing switches off services, slows networks or fills disks on purpose, to prove the system degrades gracefully and recovers. We start in test environments, agree the limits with your operations team, and only run controlled experiments in production when monitoring and rollback are proven.

How do you test integrations with banks, payment providers or ERPs?

We use the partner's sandbox where one exists and simulators where it does not, so tests run on every change. Test data covers rejected payments, timeouts, duplicate messages and partial failures, and end-to-end checks confirm that totals reconcile across systems.

Ready to build? Ask for a proposal.

Send your requirements or RFP. Our architects validate them and return a binding, fixed-scope proposal.

What happens next

  1. Readiness review

    In a free 48-hour readiness review, a Principal Architect checks your project against the 6-point Definition of Ready and recommends the track that fits.

  2. Binding proposal

    After architecture validation at no cost, you receive a binding, fixed-scope proposal within 3–5 business days: milestones, architecture, team structure and SLAs. We sign a non-disclosure agreement (NDA) with you on request, before you share your requirements.

  3. Mobilisation

    Once you sign, our engineering pods begin Sprint 0 within 5–10 business days of contract signature.

  4. Delivery in five stages

    Mobilisation, sprints with live demonstrations, integration and hardening, acceptance and go-live, then managed services. After launch comes a warranty period, then optional support and maintenance.
