Industries: — FinTech — Media — Ecomm — and more! ----- Here are some of the case studies of the clients I have helped with: 1. MONETRACK - Deploying a client stack in minutes on AWS instead of weeks Industry: Finance Problem: An unreliable process that caused constant frustration and delays. Process: Each deployment would take days to weeks to be set up, requiring between 5-6 people. Results: They now deploy a client stack in minutes instead of weeks using AWS EKS and a customised CI/CD process. In addition, I have: · Improved deployment time from weeks to minutes. · 80% reduction in costs per deployment. · Secure alignment with their client's compliance requirements. 2. Tourism Media - Great flexibility, deploying applications faster and secure on AWS Industry: Media Problem: With no CI/CD integration across all deploys, the job to integrate each stack was inconsistent and pruned to errors. Process: Deployment was not consistent across the board; they were also not resource-friendly Result: They can now push out a consistent deployment process across the company while being quickly adopted by their teams. In addition, I also have: · Improved deployment time by 60% · 70% costs reduction in EC2 instances · Greater scalability and reliability than their Legacy infrastructure. 3. Value-Ad - Scale 10X more on AWS with great stability and without the extra cost. Industry: Finance Problem: An infrastructure that could not scale securely and effectively was harming their client base. Solution: Deploy a new AWS EKS (Kubernetes) environment that is scalable, highly available, secure (PCI-DSS compliant) and cost optimised using AWS Well Architect Framework best practices. Result: They can now handle 10X more requests with excellent stability and without extra cost than their legacy infrastructure. In addition, I have added: · Greater scalability and reliability · Deployments are simplified and done in minutes instead of hours · 32% cheaper than its previous infrastructure ----- Now a bit of myself: I'm a passionate professional with 25 years of experience in enabling business strategies through the practical application of technology architecture principles, practices, and tools. User-centric and solution-oriented, I have managed projects and teams across Australia, New Zealand, the USA, Brazil, the UK, Ukraine, Singapore, Vietnam and India over the past 14 years.
