Hello, I’m Yuvii — a web developer evolving into Generative AI development.

For over 15 years I’ve built web applications that people rely on every day — custom CMS platforms, e-commerce systems, multi-tenant SaaS dashboards, and the integration layers that hold it all together. The craft of shipping reliable software under real-world constraints is what I know best, and it’s the foundation I’m now bringing to the Generative AI space.

Today, my focus is on building production-grade GenAI applications: LLM-powered tools, retrieval-augmented assistants, and agentic workflows that solve actual business problems rather than just demo well. My engineering background means I approach AI as a tool to be integrated thoughtfully — with attention to latency, cost, evals, and the messy realities of real-world data.

If you’re looking for a developer who can bridge traditional web engineering with modern AI capabilities, I’d like to hear from you.

Generative AI

LLM Application Development

I build on the leading LLM APIs — OpenAI and Anthropic — designing chat interfaces, structured-output pipelines, and prompt workflows that hold up in production. My focus is on writing prompts that are testable, observable, and maintainable over time.

Retrieval-Augmented Generation

I design and ship RAG systems for document search, internal knowledge tools, and context-aware assistants. This covers the full pipeline — from chunking strategy and embedding model choice through vector search, re-ranking, and response grounding.

Agents & Tool Use

I build multi-step agents that use tools to complete real tasks — research assistants, automation workflows, and integrations that connect LLMs to existing systems. I work with function calling, the Model Context Protocol (MCP), and agent orchestration frameworks.

Web Development

PHP & Laravel

My longest-running specialty. I’ve shipped Laravel applications from custom dashboards to complex sync engines — including a platform that orchestrates unlimited WooCommerce storefronts (orders, customers, products) from a single admin panel via webhooks.

JavaScript & Node.js

JavaScript is the language I always come back to — flexible, ubiquitous, and endlessly productive. I build on Node.js for servers and tooling, and I’m comfortable across the modern React ecosystem on the frontend.

WordPress

WordPress expanded the market for developers rather than replacing it. I’ve built custom themes, plugins, and multi-site architectures, and I know how to make WordPress perform under real traffic.

AWS & Cloud Infrastructure

AWS is my infrastructure of choice — predictable, deeply instrumented, and pay-as-you-go. I’ve built everything from Lambda-driven pipelines to CloudFront-fronted static sites (including this one).

Git & Deployment

I set up branching strategies, CI/CD pipelines, and deployment automation that match how a team actually ships — not how a blog post says they should. Reach out if you need help untangling a workflow or designing one from scratch.
