Skills

Technologies, methodologies and soft skills I work with.

Soft Skills

Adaptability

Quick learning and adapting to new technologies

Communication

Clear articulation with stakeholders and team members

Leadership & Mentoring

Leading cross-functional teams and mentoring junior developers

Problem Solving

Analytical thinking and creative solution finding

Conflict Resolution

Mediating disagreements constructively and aligning teams toward shared goals

Strategic Thinking

Long-term planning and architectural decision making

Team Collaboration

Effective collaboration and supporting team success

Concepts

Delivery & Team Practices

Agile

Iterative delivery with short feedback loops, continuous improvement, and close collaboration between development and stakeholders.

Scrum

Sprint-based framework with defined roles (Product Owner, Scrum Master, Dev Team) to ship increments regularly and adapt quickly.

Kanban

Flow-based approach visualising work in progress, limiting WIP to reduce bottlenecks and improve throughput.

CI/CD

Automating build, test, and deployment pipelines to enable fast, reliable, and repeatable software delivery with minimal manual intervention.

Architecture

Domain Driven Design

Modelling software around the business domain using Ubiquitous Language, Bounded Contexts, and rich domain models.

Microservices

Decomposing applications into independently deployable services with clear boundaries, enabling autonomous teams and targeted scaling.

Hexagonal Architecture

Isolating the application core via ports and adapters, allowing external systems (DBs, UIs, APIs) to be swapped without touching business logic.

Clean Architecture

Structuring systems into independent layers (entities, use cases, adapters, infrastructure) to keep business logic decoupled from frameworks and delivery mechanisms.

CQRS

Separating read and write models to optimise each independently, often combined with Event Sourcing for scalable architectures.

Event Sourcing

Persisting state as an immutable sequence of domain events, enabling full auditability and temporal queries.

API-First Design

Designing APIs as first-class products before implementation, using contracts (OpenAPI, GraphQL schema) to decouple teams and enable parallel development.

Engineering Quality

Test Driven Development

Writing failing tests before implementation to drive design, ensure correctness, and build a living safety net.

Behavior Driven Development

Expressing requirements as human-readable scenarios (Given/When/Then) that double as automated acceptance tests.
