What I'm looking for

I’m looking for a team where I own end-to-end systems—combining scalable engineering with AI-driven features—while prioritizing reliability, strong observability, and measurable product impact.

I’m a Senior Full Stack Software Engineer with 11+ years of experience building and operating production-grade systems across SaaS, fintech, and AI-driven platforms. I specialize in end-to-end ownership of scalable applications and designing AI-powered systems, including agentic workflows, retrieval-augmented generation (RAG), and tool-integrated LLM pipelines.

At Intercom, I designed and built an AI support automation system using RAG and agent-oriented workflows, reducing manual support workload by ~35% while maintaining response quality through evaluation pipelines and guardrails. I also lead full lifecycle delivery of platform features with a strong reliability focus—using microservices (Node.js, AWS Lambda), and observability practices (Datadog, CloudWatch) to improve incident response.
