01 / Problems we solve
Difficult software problems, made explicit.
We start with the operating problem and connect architecture decisions to practical delivery.
Backend & platform engineering
Build dependable services, APIs and business logic around real operating constraints.
Solution architecture & technical discovery
Turn ambiguous requirements into explicit boundaries, trade-offs and a delivery plan.
Systems integration & API engineering
Connect applications, data and third parties without introducing brittle dependencies.
CI/CD, deployment & engineering enablement
Make build, test and deployment repeatable, visible and recoverable.
Security-aware engineering & technical risk review
Identify practical application and delivery risks early and design proportionate controls.
02 / Working method
From uncertainty to an operable system.
Five stages keep architecture connected to implementation, production readiness and the people who will own the result.
Discover
Stakeholders, current state, constraints, risks, dependencies and success criteria.
Model
Architecture, interfaces, data flow, deployment path and delivery slices.
Deliver
Small demonstrable increments with visible progress and realistic estimates.
Harden
Testing, security checks, failure handling, observability and production readiness.
Transfer
Documentation, handover, operational knowledge and a clear next-step roadmap.
03 / Architecture thinking
Decisions need visible consequences.
A useful architecture model shows where trust changes, what can fail, who owns recovery and how software reaches production.

04 / Delivery capability
Hands-on support across the application lifecycle.
From migrating an existing application to delivering new workflows, we connect stakeholder requirements to implementation, deployment and documentation.
APPLICATION MIGRATION
Move important applications with less operational risk
- CONTEXT
- Business applications often need to move from ageing or unsupported servers without interrupting the work they enable.
- DELIVERY
- Assess the application and its dependencies, prepare the target environment, plan data and configuration migration, and manage deployment verification.
- APPROACH
- Document the current state, test the migration path, automate repeatable steps and define rollback and support arrangements before cutover.
- OUTCOME
- A controlled migration with a clear deployment record, support documentation and a practical route for future improvement.
APPLICATION DELIVERY
Turn operational requirements into dependable business software
- CONTEXT
- Teams need applications that reflect how their organisation works, not generic features disconnected from real processes.
- DELIVERY
- Gather requirements, define the solution, develop and test the application, prepare deployment and produce technical and user-facing documentation.
- APPROACH
- Deliver in visible increments so stakeholders can verify workflows early while architecture, security and maintainability remain part of the design.
- OUTCOME
- A production-ready application with an understood operating model, documented decisions and a maintainable delivery path.
ENHANCEMENT & INTEGRATION
Improve existing applications without losing business knowledge
- CONTEXT
- An existing application may still be valuable while its interface, workflow, integrations or release process limits the organisation.
- DELIVERY
- Map current behaviour, prioritise improvements, modernise interfaces and workflows, integrate surrounding systems and strengthen deployment practices.
- APPROACH
- Preserve useful domain behaviour, isolate fragile dependencies and introduce improvements in slices that can be tested and operated safely.
- OUTCOME
- A more usable and supportable application with clearer interfaces, repeatable delivery and a roadmap for further modernisation.

06 / How we contribute
We make complex software change easier to plan, deliver and operate.
AlternativeAF Technologies helps organisations move from uncertain requirements and ageing applications to maintainable software that supports day-to-day operations.
We work across stakeholder discovery, solution design, implementation, migration, deployment and handover. Decisions are explained clearly, risks are addressed early and the finished system is documented for the people who will support it.
