Vernon Simms

I’m a Senior Full-Stack Engineer with 10+ years of experience architecting scalable, Cloud-Native Infrastructure and high-performance Microservices Architecture. I specialize in turning complex data workflows into resilient, production-grade systems—especially real-time pipelines and Retrieval-Augmented Generation (RAG) applications.

I’ve spearheaded efforts that materially improve performance and outcomes, including reducing overall system latency by 40% for enterprise platforms through RAG-enabled retrieval and optimized end-to-end processing. I blend modern Node.js and Python backends with responsive Next.js frontends to deliver resilient, data-driven web solutions.

At IBM, I architected Microservices Architecture with Python 3.12+ and FastAPI, scaling RESTful APIs to process millions of requests daily while reducing response latency by 30%. I integrated RAG using LangChain and Vector Databases (Chroma/Pinecone), migrated monoliths to Docker and Kubernetes (K8s) to improve reliability by 30%, and used Kafka and WebSockets to enable real-time synchronization—reducing feature delivery time by 20%.

Earlier, at Brenzor, I built high-throughput backend services using Node.js, NestJS, and Django, improving API response times by 30%, and developed resilient ETL pipelines with Celery and RabbitMQ that reduced manual reporting overhead by 40%. At Telstra Purple, I engineered responsive React/Next.js applications, implemented micro-frontends with Tailwind CSS, and strengthened accessibility and quality using WCAG and Cypress—reducing user bounce rates by 20%.
