1. Modern Data Stack Migration
Transitioning legacy on-premises SQL Server databases to cloud-ready environments using Docker and dbt. I specialise in modularising old stored procedures into clean, version-controlled data models that your team can actually maintain.
2. Custom Internal SaaS Tools
Replacing slow, manual spreadsheets with high-performance desktop or web applications. Using Go and React, I build "local-first" tools like BoM managers or device analytics services that keep your sensitive data secure and offline.
3. Real-time Pipeline Engineering
Building robust "Event-Driven" pipelines to move data from APIs to storage. I implement Kafka and MinIO architectures to ensure your data flows are real-time, resilient, and scalable, moving you away from fragile batch processing.
4. Infrastructure as Code (IaC) & DevOps
Automating your deployment and infrastructure setup using Terraform and GitHub Actions. I ensure your data tools and applications are reproducible and easy to scale across any cloud provider, reducing manual setup errors.
