What I'm looking for

I’m looking for a remote, full-stack role where I can own system design end-to-end—building scalable backend APIs and React-driven experiences—while strengthening CI/CD and mentoring teams. I’m open to worldwide relocation and visa sponsorship.

I am a Full Stack Software Engineer with 7+ years building scalable, cloud-native systems across Clean Energy, Logistics, and Operational Analytics for UK, US, and South African clients. I specialise in backend development (TypeScript, Node.js, Python, AWS) with strong frontend experience in React.

I take full ownership from system design through to CI/CD and team mentorship. I’ve delivered high-performance APIs, event-driven microservices, and real-time platforms for international remote teams—especially in early-stage startups where I adapted quickly with limited resources and fast-moving requirements.

Most recently, I led the conversion of a codebase into a monorepo structure and implemented GitLab CI/CD to automate build, test, and deployment workflows. I also built and productionized a scalable data ingestion platform to replace spreadsheet-based processes, including historical backfill and automated cron scheduling to handle high-volume workloads reliably.

Across prior roles, I designed multi-tenant RESTful and GraphQL APIs, integrated DHL/DPD/ShipEngine for automated label generation and real-time tracking, and built returns and exchanges functionality. Earlier work includes scalable FastAPI services with async PostgreSQL for real-time tracking and alerting, performance improvements via SQL optimization and indexing, and mentoring developers on backend best practices and testing strategies.
