Fusion UX Doctor is an AI-powered webpage auditor built entirely in Fusion by Builder.io (http://Builder.io). Paste any URL and instantly get a complete UX, Accessibility, and Performance analysis, followed by AI-generated layout improvements built as real Fusion components. This project creatively uses Fusion’s visual canvas to turn audits into an interactive experience with animated cards, a clean Before/After comparison, and on-canvas component regeneration. The innovation lies in how AI doesn’t just evaluate a design, it rebuilds it directly in Fusion, proving what’s possible when design, code, and intelligence come together.

Architected an enterprise Kubernetes platform on Azure AKS for a fintech company running 40+ microservices. Traffic enters through Application Gateway with WAF v2 policies and Azure Firewall before reaching the AKS cluster inside a hub-spoke VNet. ArgoCD manages all deployments through GitOps with automatic drift detection and self-healing. ACR stores container images built by Azure DevOps Pipelines with integrated vulnerability scanning. Workloads connect to Cosmos DB, PostgreSQL Flexible Server, and Redis Cache through private endpoints. Azure ML handles fraud detection model inference called directly from within cluster pods. Entra ID with Managed Identities provides passwordless auth across all services.

Designed and deployed a multi-account AWS landing zone using Control Tower and Organizations for a healthcare SaaS company handling PHI data. The architecture separates management, security, network, and workload accounts with dedicated IAM boundaries. Traffic routes through CloudFront and WAF into a Transit Gateway hub before reaching production VPCs running ECS Fargate workloads. Security Hub aggregates findings from GuardDuty, Inspector, and AWS Config across all accounts. CloudTrail feeds into EventBridge for real-time alerting through SNS. All encryption managed through a centralized KMS account. Infrastructure provisioned entirely with Terraform and Terragrunt modules. Achieved SOC 2 Type II and HIPAA compliance within 90 days.

I built a production-ready serverless LLM API on GCP designed for low cost, strong security, and fast inference. Requests flow through CDN, load balancing, WAF, and API management before hitting a Cloud Run FastAPI service that handles prompts, session history, caching, and model routing. The system switches between Gemini 2.5 Pro for deep reasoning and Gemini Flash for fast responses, with RAG support using Vector Search over 768-dim embeddings. Data is stored in Firestore, cached in Redis, and logged to BigQuery. Everything is secured with VPC Service Controls, Workload Identity, KMS, Secret Manager, and DLP. CI/CD is fully automated with Terraform and Cloud Build using canary rollouts and auto-rollback on SLO violations. At around 50K requests per day, the platform runs at about $1K/month and scales to zero when idle.

Here's how I'd build a scalable ticketing backend with Supabase & Stripe. The backend is where everything lives or breaks. Supabase handles auth and Row Level Security out of the box, Postgres enforces ticket inventory and access at the database level, and Stripe Checkout processes payments with webhooks that keep everything in sync. Capacity limits, discount logic, and user access all of it stay consistent when real traffic hits. Built to scale without needing a full rewrite six months down the road.

Conducted a full cybersecurity risk assessment for NexaSoft's AWS EKS-hosted Employee Self-Service HR Portal, processing sensitive employee PII including payroll, health records, and government-issued ID. Identified three Critical and five High risks across Azure AD SSO, cloud IAM configuration, and insider privilege controls, aligned to ISO 27001. Delivered a prioritised 90-day remediation roadmap using native AWS and Azure tooling, reducing all Critical risks before go-live and supporting the client's ongoing ISO 27001 certification obligations under Australia's Privacy Act 1988.

Deployed a cloud-native SIEM integrating Microsoft Azure infrastructure, Windows endpoints, Microsoft 365, and Defender XDR telemetry into a unified detection and response platform. Wrote KQL analytics rules for real-time threat detection covering: privilege escalation, suspicious PowerShell execution, lateral movement via RDP and SMB, anomalous Azure AD sign-ins, and malware execution patterns. Automated incident response using Azure Logic Apps. Reduced log ingestion costs by 20% through optimised data collection, balancing coverage against cost without losing detection fidelity.

Performed a read-only Microsoft 365 security assessment for an 11-user UK logistics company, uncovering two Critical findings: MFA disabled on Global Administrator accounts and an active email forwarding rule on the Finance Manager's mailbox consistent with Business Email Compromise. Delivered a clear priority action plan, all remediable within 72 hours using tools already included in the client's existing M365 licence along with SharePoint sharing controls and Conditional Access policy configuration to close legacy authentication gaps.

Delivered a GRC-aligned cybersecurity risk assessment for an Azure-hosted AI-Driven HR Analytics Service processing employee PII and behavioural data. This engagement went beyond conventional security reviews to address AI-specific risks including data poisoning and model bias that carry direct legal exposure under the Canadian Human Rights Act and the proposed AI and Data Act (AIDA). Identified five High risks and produced a mitigation strategy using Azure-native controls, alongside governance recommendations to ensure compliant and auditable AI decision-making ahead of AIDA enforcement.
