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.

I'm a Senior AI Engineer and Full Stack Developer with 12+ years of experience building web, mobile, and AI-powered products for businesses across SaaS, FinTech, Healthcare, and E-commerce. In recent years, my focus has shifted toward helping businesses integrate AI in ways that are genuinely useful - not AI for the sake of trend-chasing, but solutions that solve real problems, improve user experience, and give your product a lasting competitive edge. If you're looking to add AI to an existing app, build something new from scratch, or automate manual workflows, I can help you think it through strategically and build something that performs reliably in production. 🔹 AI Applications & Intelligent Automation Custom AI applications powered by OpenAI, Claude, Gemini, and open-source LLMs AI chatbots and virtual assistants RAG (Retrieval-Augmented Generation) systems AI agents and multi-agent workflows Business process automation with n8n, Make, Zapier, and custom APIs 🔹 Full Stack Web Development React, Next.js, and Angular frontends Node.js, FastAPI, Django, and Laravel backends REST API design and third-party integrations Secure authentication and role-based access control Scalable SaaS platforms and internal business tools 🔹 Mobile App Development Cross-platform apps with React Native High-performance native iOS and Android development API integration and real-time features App optimization, performance tuning, and ongoing maintenance 🔹 My Approach Every successful product starts with understanding the business - not writing code. Before development begins, I identify: How users interact with the system Where manual work can be automated Potential performance bottlenecks The architecture needed to support future growth This approach minimizes technical debt, avoids costly rebuilds, and produces software that's easier to scale and maintain long-term. 🔹 Core Technologies AI & Automation: OpenAI, Claude, Gemini, LangChain, LangGraph, CrewAI, AutoGen, LlamaIndex, GoHighLevel (GHL), Pinecone, Weaviate, pgvector, Prompt Engineering, RAG, AI Agents, n8n, Make, Zapier Frontend: React, Next.js, Angular, TypeScript, JavaScript Backend: Node.js, Python, FastAPI, Django, Laravel Database: PostgreSQL, MongoDB, Redis Cloud & DevOps: AWS, Google Cloud, Azure, Docker, Kubernetes, CI/CD 🔹 Why Clients Choose to Work With Me ✔ Solutions built for real users, not just prototypes ✔ Scalable architecture that grows with your business ✔ Clean, maintainable code that future teams can easily extend ✔ Clear communication focused on business outcomes, not just technical output ✔ Full ownership - from planning and architecture through deployment and long-term support Industries Served: SaaS • AI Products • Healthcare • FinTech • Logistics • E-commerce • Marketplaces • Internal Business Platforms • Customer Portals If you need an engineer who can combine AI, full-stack development, mobile apps, and automation into one cohesive, scalable solution.
