Current-state assessment
Map the existing application, dependencies, data flows, trust boundaries, deployment model, and operational constraints. Identify bottlenecks and risks from evidence rather than assuming that a rewrite is necessary.

Digital Architecture
Architecture is about making the important boundaries explicit: data, services, users, integrations, security, failure modes, and the path from today's system to tomorrow's.
Based in Kampala, Uganda; available for remote collaboration with clients internationally.
What I design
- Application and service boundaries
- API contracts and integration architecture
- Database relationships and data ownership
- Authentication, authorization, and security boundaries
- Performance, caching, observability, backup, and recovery strategies
Architecture principles
- Prefer simple boundaries that can be explained
- Design around real workload and failure modes
- Keep security and data integrity inside the architecture
- Measure before scaling infrastructure
- Document decisions so systems remain maintainable
Architecture that guides implementation
Useful architecture work makes decisions easier to explain and safer to change. It connects business requirements to system boundaries, data ownership, integrations, security controls, operational responsibilities, and a realistic migration path. The output should help a team build and operate the system—not become a diagram that nobody uses.
Target-state design
Define service and module boundaries, API contracts, database ownership, integration patterns, identity and access controls, observability, and recovery expectations appropriate to the workload.
Migration and decisions
Document important trade-offs, sequencing, compatibility concerns, rollback options, and the operational changes needed to move safely. Separate immediate fixes from longer-term architectural improvements.
Typical deliverables
- Current-state and target-state architecture diagrams.
- System context, component, data-flow, and integration views where useful.
- Architecture decision records explaining key trade-offs.
- Risk register covering security, reliability, performance, and operational ownership.
- Phased implementation or migration plan with validation checkpoints.
When is an architecture review useful?
Consider one before a major product build, a database or platform migration, a security-sensitive integration, or when delivery has become difficult because responsibilities and dependencies are unclear. The review can be scoped to a single critical workflow or a wider system, depending on the decision you need to make.
Does architecture mean introducing microservices? No. A well-structured monolith or modular application may be the simpler and more reliable choice. The design should follow the team's needs, workload, and ability to operate it.

Work with me
If you have a product, workflow, system, or technical problem that needs to become real software, start with the requirements and constraints. I can help turn them into an implementation plan and a production-focused build.
