• Oversee end-to-end site operations, ensuring production targets and quality standards are consistently met.
• Manage, train, and develop a team of employees covering machinery operation, chemical handling, and safety compliance.
• Inspect and maintain a diverse fleet of machinery including forklifts, screening, and mixing equipment.
• Own and manage operational budgets, preventing overspend while hitting output targets.
• Evaluate and onboard new plant machinery through supplier meetings and trials.
• Coordinate haulage logistics and supply chain movement of products.
• Ensure full compliance with health, safety, and environmental regulations across all operations.

• Managed inbound goods scanning, damage inspection, and inventory coding.
• Operated clamp trucks and shunted trailers; maintained warehouse cleanliness and organisation.
• Provided office cover, demonstrating adaptability across operational and administrative functions.

Also undertook a concurrent part-time role at Ces't (bar work) to fund driving licence.

• Managed cold-chain logistics for meat products, ensuring correct storage locations and dispatch readiness.
• Coordinated closely with production teams to maintain a steady supply pipeline.
• Picked and shrink-wrapped orders for delivery with correct barcodes.

• Operated counterbalance forklift and managed high-risk filling processes.
• Maintained pipework, vessels, and equipment readiness; completed efficiency and compliance paperwork.
• Ensured product flow and area hygiene across packing and filling departments.

• Designed and implemented a full enterprise multi-tier architecture: VPC networking (public/private subnets, NAT, NACLs, flow logs), RDS Aurora PostgreSQL Multi-AZ, ElastiCache Redis with failover, and ECS Fargate auto scaling.
• Built defence-in-depth security: WAF managed rules, GuardDuty/Config/Security Hub, IAM permission boundaries with role chaining, KMS encryption governance with grants, and Secrets Manager 30-day automatic rotation.
• Implemented Cognito OAuth2/OIDC authentication, API Gateway with usage plans and throttling, CloudFront CDN with geo-restrictions, and cross-region disaster recovery (Route 53 failover, RPO 1h / RTO 4h).
• Provisioned 22 Terraform modules composed through a root module with CloudWatch composite alarms, anomaly detection, S3 lifecycle management, AWS Backup with cross-region vaults, and Service Quotas monitoring.
• Built Python FastAPI application with cache-aside pattern, structured JSON logging, and GitHub Actions CI/CD (OIDC federation, Checkov/tfsec security scanning).
• Validated with 267 automated tests including 10 property-based invariants (Hypothesis). Zero-cost local dev via Docker Compose + LocalStack; on-demand AWS demo < £5.
• Documented with 7 ADRs, Well-Architected Framework review (all 6 pillars), DR runbooks, security posture summary, and skills matrix.

• Designed and built an enterprise-grade event-driven platform processing e-commerce events through EventBridge, SQS, and Lambda with schema validation and content-based routing.
• Orchestrated order workflows with Step Functions (parallel processing, human approval gates, Map state, retry policies).
• Built a serverless data lake (S3 Parquet, Glue crawlers, Athena) with real-time Kinesis streaming aggregations to DynamoDB.
• Implemented an AI Query Service using Bedrock (Claude) with RAG pattern — natural language to SQL with retry and cost controls.
• Provisioned 9 Terraform modules with least-privilege IAM, KMS encryption, and security scanning (Checkov).
• Validated with 460 automated tests including 11 property-based invariants (Hypothesis). Full local dev via LocalStack — zero AWS cost.
• Documented with 5 ADRs, Well-Architected Framework review, cost analysis, and Strangler Fig migration strategy.

• Built EKS cluster provisioning with Terraform modules, GitOps deployment via ArgoCD, and Helm chart packaging.
• Developed a Python FastAPI microservice with health checks, graceful shutdown, and container-optimised configuration.
• Implemented full observability stack: Prometheus metrics, Grafana dashboards, structured logging, and alerting rules.
• Validated with 98 automated tests including 5 property-based invariants. Zero-cost local development model.

• Architected 8 Terraform modules provisioning VPC, ECS Fargate, DynamoDB, and monitoring across dev/staging/production environments.
• Built GitHub Actions CI/CD with OIDC federation, automated rollback, security gates (tfsec/Trivy), and LocalStack integration testing.
• Implemented Lambda-based cost governance: business-hours ECS scaling, orphaned resource scanning, anomaly detection, and monthly cost reporting.
• Designed multi-account AWS Organizations with SCPs, cross-account roles, and centralised logging strategy.
• Achieved 198 automated tests including 8 property-based invariants validating business logic correctness.
• Zero-cost operational model — full local development via Docker/LocalStack; on-demand AWS demos cost < £2/session.

• Engineered an offline-first edge IoT platform using AWS IoT Greengrass v2 with 12 local Lambda components for maritime safety.
• Built real-time data fusion correlating 20+ sensor inputs (AIS, radar, GPS, engine) for collision avoidance and predictive maintenance.
• Deployed serverless cloud stack (Lambda, DynamoDB, EventBridge, SNS) operational under £2/month.
• Validated system correctness with 1,633 tests including 24 property-based invariants using fast-check.

• Deployed static site on S3 with CloudFront CDN, HTTPS, and custom domain.
• Built serverless visitor counter (API Gateway, Lambda, DynamoDB) and contact form (SES).
• Automated deployments with GitHub Actions CI/CD using OIDC federation (zero stored credentials).
• Defined all infrastructure in CloudFormation with least-privilege IAM policies.
