About me
I build backend-heavy products that need to keep working when the data gets messy, the user count grows, or multiple systems have to stay in sync. Over 4+ years I've worked across payroll, UK government education, combat sports, recruitment and legacy migrations. My strongest work is Node.js, NestJS, PostgreSQL, APIs, queues, integrations and the engineering decisions around them. I can also carry features through the frontend when needed.

Services
ENGINEERING THAT HOLDS UP IN PRODUCTION
Full-Stack Development
Features carried from database and API contracts through React, Next.js or Vue integration when the product needs end-to-end ownership.

Schemas, module boundaries, queues and workflows shaped around the actual product instead of abstract patterns.
↗︎API & Integration Engineering
REST APIs and third-party integrations including Veriff, Pusher, Knock, Firebase, Microsoft Teams and Azure Service Bus.
↗︎Performance & Data Engineering
Query work, search, pagination, background processing and high-volume migrations when response time and data volume matter.
