01 / INTERNATIONAL ARCHITECTUREYahoo
Designing for many markets without building many platforms
The challenge
International services must accommodate different market conditions, commercial expectations and operating constraints. Treating every market as a separate implementation creates long-term cost; forcing identical behaviour everywhere creates other problems.
My contribution
Worked at international-architecture level to evaluate common capabilities against country-specific requirements, with business-case and stakeholder considerations alongside technical architecture. The objective was a scalable platform approach that could support international needs while keeping complexity manageable.
What this demonstratesArchitecture is as much about selecting what should remain shared as deciding where flexibility is essential. Technical trade-offs need to be legible to business stakeholders.

Making performance a design concern, not a late-stage repair
The challenge
Large mobile service environments face demanding performance and reliability requirements. Choices about integration, execution paths and architecture become operational problems at scale.
My contribution
Contributed to performance-focused engineering and architectural decision-making in the Vodafone mobile services environment, with an emphasis on investigating constraints and directing effort where it would materially improve platform behaviour.
What this demonstratesSuccessful optimisation involves measurement, prioritisation and judgement. The goal is not merely faster code; it is better behaviour for the service as a whole.

03 / DELIVERY LEADERSHIPMinicabit
Three teams, different priorities, one shared platform
The challenge
Multiple delivery teams working against the same product can pull architecture and priorities in conflicting directions. Without coordination, local decisions can create cross-team dependencies and reporting problems.
My contribution
Managed three engineering teams with distinct objectives, balancing their delivery priorities and keeping dependencies visible. Also worked with data and reporting architecture, including separation of operational needs from reporting workloads.
What this demonstratesGiving engineering leads autonomy works best when interfaces, shared assumptions and escalation routes are clear. Organisational design is part of system design.

Turning complex fleet records into usable operational information
The challenge
Operational data often spans legacy structures, inconsistent records and systems designed for day-to-day transactions rather than downstream extraction and analysis.
My contribution
Worked on data extraction involving approximately 15,000 vehicles, addressing practical issues in mapping operational information into a usable form.
What this demonstratesData projects succeed when extraction logic, validation and the business meaning of fields are treated as first-class concerns rather than an afterthought.

05 / APPLIED AIDocument AI & local LLM systems
Useful AI needs controls, integration and a way to check its work
The challenge
Moving from a convincing demonstration to a usable system requires much more than selecting a model: document variability, privacy, verification, latency and operational cost all affect outcomes.
My contribution
Worked on document-processing workflows, AI-assisted extraction, translation, local model infrastructure and retrieval-augmented search. Designed around review steps and integration with existing systems rather than assuming model outputs should be trusted without checks.
What this demonstratesStart with the process and its failure modes. Use AI where it creates measurable value, and make human verification and operational constraints visible in the architecture.
