Professional Summary

I'm a Fullstack AI Engineer with 3+ years of hands-on experience designing, building, and deploying scalable, AI-powered web applications across healthcare, agritech, fintech, automotive, and enterprise systems. My work spans the full product lifecycle from system architecture and database design through to production deployment, observability, and post-launch iteration and I'm equally comfortable shipping a polished React/Next.js interface as I am orchestrating a LangChain pipeline or fine-tuning a TensorFlow model.

I specialize in integrating machine learning models, large language models, and retrieval-augmented generation (RAG) pipelines into modern fullstack architectures built on React, Next.js, Node.js, FastAPI, PostgreSQL, Redis, and AWS. I care deeply about system performance and developer ergonomics: I design caching strategies that cut load times by 60%+, RESTful APIs that scale to thousands of concurrent users, and containerized microservices that hold 99.9%+ uptime in production.

Beyond the codebase, I'm a co-founder who has taken products from a blank repository to real revenue and real users negotiating requirements with non-technical stakeholders, mentoring junior developers, and writing technical content on machine learning and data science. I thrive in ambiguity, communicate clearly across technical and business audiences, and I'm driven by building intelligent systems that solve genuine, real-world problems for the people who use them.
