Software Architect & Full Stack Engineer | Python, AWS, Data & MLOps

Software Architect and Full Stack Engineer with 10 years at Amazon and over 14+ years of experience building mission critical software, distributed microservices, and resilient data systems. I design stable, modular systems that handle team growth and heavy traffic without forcing future rewrites. Having engineered high throughput, compliant platforms for leaders like Amazon (10 years), Capital One, SunTrust, and Fiserv, I deliver complete products: responsive web applications, modular microservices, custom Python ETL pipelines, and automated serverless AWS infrastructure that runs without downtime. What I Build - Full Stack Applications: Modern web apps, administrative portals, and dashboards built with Next.js, React, Node.js, and TypeScript. - Microservices and Serverless Systems: Scalable REST and GraphQL microservices, event driven architectures, serverless workloads with AWS Lambda, secure authentication, and transactional database design. - Data Pipelines and Ingestion: Resilient Python ETL and ELT workflows, API extraction, webhook consumers, and schema modeling across PostgreSQL and cloud data warehouses. - Cloud and DevOps: Infrastructure as code using Terraform, containerized services with Docker and Kubernetes, and automated CI/CD pipelines on AWS. Track Record - Decomposed monolithic codebases into scalable, decoupled microservices and event driven serverless architectures, improving deployment frequency and system fault tolerance. - Engineered distributed architectures and high velocity checkout workflows processing millions in transaction volume with zero downtime. - Built custom Python ingestion services and workflow orchestration engines that process high volume partner APIs with strict schema validation. - Delivered production systems and compliance baselines meeting the rigorous security, audit, and reliability standards of Amazon and major financial institutions. - Led legacy application modernizations into cloud environments, ensuring 99.99% uptime during 5x traffic surges. Whether you need a complete web application built, a monolithic system migrated to serverless microservices, or custom API data pipelines automated on AWS, I provide senior engineering leadership and clean execution. Looking forward to building with you. Dave
