Alec Byrne

I’m a Senior Python Backend Engineer with 8+ years of experience designing and building scalable backend systems, cloud-native applications, microservices, and AI-powered solutions. I focus on high-performance APIs, distributed systems, and production-grade delivery using Python and AWS.

In my recent work, I developed backend services and microservices with Python, FastAPI, PostgreSQL, Redis, and AWS for enterprise healthcare and digital transformation. I designed RESTful APIs and asynchronous workflows for scalability and reliability, and built event-driven applications using Kafka and Redis for real-time processing and orchestration.

I also prioritize security and operational excellence—implementing JWT, OAuth2, and RBAC for secure authentication/authorization, and supporting stable deployments through Docker, Kubernetes, GitHub Actions, and AWS services. I’m comfortable owning monitoring, logging, testing, and production support to keep systems dependable as usage grows.

I’m especially strong in AI integration, using OpenAI APIs, LangChain, and RAG with vector databases and semantic search. I’ve built RAG pipelines that boosted response accuracy by 40%, reduced information retrieval time by 60%, and enabled 500K+ AI-driven queries per month, while saving 45% of manual time and increasing user productivity by 35%.
