What I'm looking for

I seek a role building scalable full-stack systems with AI integrations, automation, and real-time dashboards where I can drive measurable impact and mentor teams.

I am a Full-Stack developer with 8+ years delivering end-to-end systems using React, Node.js, TypeScript and AI-driven workflows. I have architected and launched scalable platforms and dashboards, built GPT-based automation that reduced support load by 80%, and engineered solutions that improved compliance accuracy and performance.

My work spans real-time dashboards, RAG pipelines, LangChain integrations, and automation with Make.com and Zapier; I prioritize measurable impact—cutting QA review time 70%, reducing onboarding ramp-up 40%, and scaling platforms to thousands of concurrent users—while documenting SOPs and mentoring teams to accelerate delivery.
