Matteo Parussini

Design and build Golang backend services using REST and gRPC APIs, supporting distributed cloud infrastructure; integrated OpenAI APIs and payment gateways (Stripe, Helcim) ensuring secure and efficient communication; improved system throughput and latency via database query optimization and algorithmic tuning; developed CI/CD pipelines (GitHub Actions, AWS) and automated testing suites (unit, integration with TestContainers) to ensure production reliability; contributed to observability enhancements using structured logging and performance monitoring.

Design and development of backend services in Go within a microservices architecture supporting distributed cloud infrastructure; owned end-to-end delivery — design, testing, deployment, monitoring, and performance tuning; integrated NAT S messaging, implemented caching, and improved logging and telemetry with OpenTelemetry, Grafana, and Prometheus; mentored engineers and promoted engineering best practices in code quality, performance, and observability.

Enabling digital transformation across large-scale projects for enterprise clients including IAG and Screwfix; collaborated with stakeholders to define technical requirements, provide backend architecture consulting, designed and delivered scalable, secure, and cloud-native backend platforms; built API integrations, IAM/IDAM systems, and data ingestion services with emphasis on performance and maintainability; mentored engineers, improving code quality, testing, and overall delivery efficiency.
