About Me Over the last 14+ years, I've designed and delivered web, backend, and mobile applications across multiple industries, with a strong focus on scalable backend systems, cloud architecture, and end-to-end project delivery. In recent years my work has centered on cloud-native architectures and Generative AI, including RAG pipelines on Amazon Bedrock, agentic AI systems, and backend services that power AI-driven features such as knowledge assistants, automation, and data-aware chat. I'm comfortable owning projects end to end, from architecture and development to deployment, optimization, and client communication. ☁️ AWS & Cloud Architecture I have extensive hands-on experience designing and operating systems on AWS, including: • Serverless & event-driven architectures (Lambda, API Gateway) • Backend services using EC2, ECS, ECR, Elastic Beanstalk • Storage & data services (S3, EFS, Aurora, DynamoDB, DocumentDB) • Messaging & streaming (SQS, SNS, Kinesis) • Networking, routing & security (Route 53, CloudFront, WAF) • CI/CD & DevOps (CodeCommit, CodeBuild, CodeDeploy, GitHub) • Infrastructure as Code (CloudFormation) I focus on cost efficiency, scalability, and security, especially for production systems. ⸻ 🤖 Generative AI & Agentic Systems on AWS • RAG pipelines on Amazon Bedrock (knowledge bases, retrieval layers, grounding) • Agentic AI using Bedrock Agents and the Strands Agents SDK • Amazon Q Business and Amazon Q Developer • Amazon SageMaker AI (model fine-tuning, Clarify, Model Monitor), applied in prototypes and demos • Secure integration of AI components into existing systems, plus API design for AI-assisted applications 🧠 Backend Development Languages & Frameworks • Python (FastAPI) • Node.js (Express.js) • GraphQL (Apollo Server) • PHP (Laravel, CodeIgniter, Zend) • Firebase • Go (working knowledge) 🗄️ Databases & Caching • PostgreSQL, MySQL • AWS Aurora • MongoDB / DocumentDB • DynamoDB (with DAX where appropriate) • Redis, Memcached I choose storage solutions based on access patterns, scale, and cost, not trends. 🌐 Frontend & Mobile Development Web • React.js • HTML, CSS, JavaScript • Angular / Vue (working knowledge) Mobile • React Native (including custom native modules) • Flutter • Native iOS (Swift / Objective-C) • Native Android (Java) This allows me to deliver full products, not just backend APIs. 🐳 Containers & Orchestration • Docker (single & multi-container setups), deployed on ECS/ECR in production • Kubernetes: hands-on with core workload concepts (Deployments, Services, ConfigMaps/Secrets, probes, resource limits, troubleshooting), • Docker Swarm (legacy support) 🎓 Certifications & Professional Background • AWS Certified Solutions Architect – Associate • AWS Certified AI Practitioner • Professional Scrum Master (PSM I) • Experience leading teams and working in Agile environments 🤝 What You Can Expect • Clear communication & realistic estimates • Strong ownership mindset • Production-first thinking (not just prototypes) • Ability to combine backend, cloud, mobile, and AI into one solution If you're looking for someone who can build your application today and evolve it with AI tomorrow, I'd be happy to discuss your project.
