What I build


Backend Systems

Server-side architecture designed for reliability — relational schemas, REST APIs, service design, and the operational discipline that keeps them running in production.

Node.js · PostgreSQL · Redis

API Engineering

Clean, versioned contracts with a focus on developer experience, security, and performance. From OpenAPI specs to payment gateway integrations and third-party messaging.

Express · FastAPI · Stripe · Twilio

Performance & DevOps

Optimisation built in from day one — multi-layer caching, query tuning, async processing, and containerised deployments that scale predictably under load.

Docker · Redis · Linux · CI/CD
