About Me
Building digital
Building digital
experiences that matter.
Senior software engineer with over a decade building back-end systems, APIs, and cloud infrastructure at scale. I specialize in PHP, Node.js, AWS, and database design — and bring full front-end fluency when the work calls for it. From serverless architectures processing high-volume event streams to LLM-integrated content platforms serving millions, I focus on systems that are reliable, maintainable, and built to grow.
API & Systems Design
I design clean API contracts and database schemas first — then build the services and integrations around them.
Cloud-Native Engineering
Experienced with AWS Lambda, SQS, and serverless patterns — architecting infrastructure that scales without babysitting.
AI/LLM Integration
Hands-on with LLM APIs, RAG pipelines, prompt engineering, and AI-driven workflow automation in production systems.
