For founders and early-stage startups: I deliver complete, multi-tenant platforms with real users, real data, and real revenue potential. Architecture, cloud setup, databases, role-based access, AI/chat search, payments, admin portals - all production-ready from day one. No throwaway prototypes. Everything ships ready to scale. For scaling companies: Seven years of DevOps experience across Finance, Web3, and Data Analytics. Kubernetes platforms, cloud migrations, and build environments for growing engineering teams. What sets me apart is that I do both. Most MVP developers hand you something that breaks at scale. Most DevOps engineers won't touch product development. I bridge that gap by building MVPs on solid foundations so you're not rewriting everything six months later. What you get: - Zero upfront infrastructure costs - Pay-per-user scaling as you grow - Multi-tenant architecture with role-based access - Cloud infrastructure (AWS, GCP, Azure) - AI/chat search integration - Direct debit Payment processing - Admin portals and dashboards - Full source code ownership - Self-hosting support and documentation Infrastructure & DevOps skills: Cloud: ControlPlanne, AWS, Azure, GCP, DigitalOcean, Hetzner, on-premise Orchestration: Kubernetes, Rancher, Docker Swarm, OpenShift IaC: Pulumi, Terraform, CloudFormation CI/CD: Jenkins, Helm, GoCD, Github Actions, Tilt, Earthly Databases: PostgreSQL, MySQL, MongoDB, Elasticsearch, MSSQL Languages: Python, TypeScript, JavaScript, Go, Bash, PowerShell Recent achievements: - Re-engineered SaaS architecture to Kubernetes microservices, cutting software spend by 40% - Built automated multi-cloud disaster recovery with Terraform - Delivered end-to-end MVP platforms for B2B marketplace taking them from £0 to £3M valuation in 3 months - Product Owner and Scrum Master for Agile mobile app development Certifications: - Kubernetes Certified Administrator (CKA) - Kubernetes Certified Application Developer (CKAD) - AWS Certified Developer Associate - Agile Certified Practitioner - 1st Class Honours, Electronic Engineering & Cybernetics
