I build AI features that ship to production: LLM agents, RAG chatbots, and model integrations with Claude, GPT and Gemini, backed by 6 years of full stack engineering with Ruby on Rails, React and React Native.
For the past two years most of my work has been AI engineering inside real products, not demos. I'm a core engineer on Pressbot, an AI platform that turns a URL or topic into finished news articles. I built its model selection and prompt refinement workflows and wired in Anthropic, OpenAI, HeyGen, Jina AI, Firecrawl and MediaStack. Those features helped lift user engagement by 20%.
Before that I spent years shipping web and mobile apps for funded startups, which is why my AI work holds up in production. I know the parts that make LLM features reliable: background jobs, retries, rate limits, webhooks, caching, and solid PostgreSQL schema design.
I also use AI to build faster. Claude Code, Codex and Cursor are part of my daily workflow. A recent example: a 6,000+ line architectural refactor on a large insurance CRM, planned and shipped in two days with full test coverage. Same quality bar, a fraction of the usual timeline. That speed is what lets my clients validate ideas quickly and ship sooner.
What I can help you with:
🤖 AI features in your product: chatbots, agents, RAG over your docs or data, model integrations
🚀 An MVP web or mobile app, from idea to deployed
📱 iOS and Android apps from a single React Native codebase
🐛 An urgent bug. If I can't fix it, you don't pay
🕹️ A senior engineer slotting into your existing team to ship features
🌟 Web scraping and data pipelines for research and comparison
My stack:
Languages: Ruby, JavaScript, TypeScript, Python
AI and LLM: Anthropic Claude, OpenAI GPT models, Google Gemini, RubyLLM, prompt design, embeddings and vector search in PostgreSQL
Rails: versions 5 through 8, Sidekiq, Resque, SolidQueue, RSpec, ActiveAdmin, Avo
Frontend and mobile: React, Next.js, React Native, Expo
Databases: PostgreSQL, MySQL, MongoDB, Redis
Deployment: AWS, Heroku, Docker, Kamal, Capistrano
AI dev tools I use daily: Claude Code, OpenAI Codex, Cursor, Cline, Lovable
Also comfortable with: Django, Shopify, Elasticsearch
Happy to start small. A paid trial task or a short call works for me, and you'll know within a week if I'm the right fit. Tell me what you're building.
