I build fast, scalable web applications using Cloudflare (Workers, D1, Durable Objects), modern frontend frameworks, and AI. Over the last 12+ years, I’ve worked as a fullstack engineer and team lead, shipping production systems used in real-world businesses. Recently, I’ve been focused on edge-first architecture and AI-powered products. What I can help you with: Build SaaS products from scratch (MVP → Production) Develop Cloudflare-based apps (Workers, KV, D1, Durable Objects) AI integrations (OpenAI, Gemini, Vercel AI SDK) Frontend development (React, SvelteKit, performance-focused UI) Backend systems (Node.js, TypeScript, Go) API design, system architecture, and scaling Recent work: Built an AI-powered static site generator running fully on Cloudflare Developed an edge-based invoice generator with PDF rendering Created an offline-first accounting app with sync architecture Built an AI-powered learning platform with high concurrency I focus on clean architecture, performance, and reliability — not just shipping features. If you’re building something serious and need someone who understands both product and engineering, I’d be happy to help.

I build the plumbing behind AI products — the multi-API orchestration, the webhook pipelines, the retrieval layers, the data flow that has to work every time a user hits the button. A lot of people can prompt an LLM. The harder part is everything around it, and that's the part I've been shipping in production for the last few years. My stack is React + Vite on the frontend, tRPC + Express + Postgres + Drizzle on the backend, and OpenRouter / Claude / OpenAI wherever the model calls live. I use n8n for workflow orchestration when it fits, and write it in code when it doesn't. A quick note on my Upwork history: most of my visible past jobs here are telecom / SMS / IVR / API integration work from 2018 to 2022 — that was my previous chapter. Since 2023 I've moved almost entirely into AI infrastructure and agentic automation, and that's where I'm taking on new work. A few things I've shipped recently (details sanitized for NDA): - A multi-source audit and business-intelligence pipeline pulling from roughly 15 external APIs (search, social, review, directory, analytics). Normalizes the data, runs it through an LLM-assisted scoring layer, and produces a client-ready report end to end — with webhook plumbing, retries, and caching. - A production RAG / content-generation system for a CMS-style product. Embeddings, section-level generation, prompt chains, editorial controls. The kind of system that has to stay correct as the content library grows past thousands of items. - An SSR-optimized financial SaaS calculator with programmatic SEO. Thousands of landing pages, full server-rendered, real tax and yield math under the hood — not a toy. - A local-business reputation pipeline that ingests reviews across sources, dedupes, sentiment-scores, and feeds a response-automation layer. What I'm best at: - Agentic workflow automation — n8n, custom Node orchestration, Claude / OpenRouter integrations, webhook-driven pipelines. - LLM infrastructure — RAG, embeddings, prompt architecture, eval loops, retrieval tuning. - FinTech / calculator / SaaS MVPs where the math has to be right and the product actually ships. - Senior full-stack work on the exact stack above, when AI integration is part of the brief. How I work: I take specs seriously. Hand me a 10-page doc, I'll read it, come back with questions, then build what's in it. I prefer small, reviewable PRs over big drops. I don't subcontract the hard parts — you get me on the actual work. Two things I'm not: I don't take healthcare / dental / ortho projects (existing exclusivity), and I'm not the right fit for generic React-only landing-page builds without an AI layer. Plenty of great freelancers here for that. 243 jobs, $200K+ earned on Upwork, 100% Job Success. If the project is in my lane, I'll tell you straight. If it isn't, I'll tell you that too.
