AI Software Engineer | Web, Mobile & AI Apps | Full-Stack Development

TOP RATED PLUS · AI Software Engineer Have an AI product idea, a half-built prototype, or an internal process that's outgrown spreadsheets and no-code? I help founders and businesses turn those into AI-powered products, internal tools, and scalable software, without burning months or a six-figure budget getting there. I build production AI and web apps for founders and businesses: products your customers use, tools your team relies on, and platforms that run real operations. I spent years automating businesses with n8n, Make, and Zapier before writing this kind of code. So I know when no-code is enough, and when you need a real system. When the tools hit their ceiling, I build what comes next. 🔹 HOW I CAN HELP YOU ✅ Full-Stack AI Apps & Platforms Turn your idea into a production app: customer-facing products, internal tools, or multi-tenant SaaS. Next.js, Postgres, auth, Stripe, background jobs, and clean APIs from MVP to scale. ✅ AI Products for Your Customers Build the AI experience your users interact with: chat assistants, smart workflows, personalized recommendations, and features that make your product feel intelligent. ✅ Internal Tools That Run Your Business Replace spreadsheets, inboxes, and manual ops with AI-powered tools your team actually uses, like dashboards, review flows, knowledge bases, and automations. ✅ Document & Data Intelligence Turn invoices, POs, contracts, emails, and messy files into clean, structured data your business can act on, with human review when accuracy matters. ✅ Automations That Scale With You When Zapier, Make, or n8n hit their ceiling, I rebuild them as real software that's reliable, testable, and ready to grow with your company. ✅ From Prototype to Production Already building in Lovable, Bubble, Replit, or Cursor? I take what works, harden it, and ship something your customers and team can rely on. 🔹 RECENT WORK • Multi-tenant AI SaaS for competitive ad intelligence: streaming chat, vision and video analysis, Slack agents, MCP, Stripe billing • Human-in-the-loop AI training platform with RAG, embeddings, LLM-as-judge evals, and prompt versioning • Document AI for manufacturers: Claude reads PDFs natively, extracts structured data, and captures corrections • Agentic B2B outbound engine: research agents, ICP scoring, personalized email drafting, and durable workflows • Python email RAG pipeline: years of Outlook history turned into a searchable knowledge base • Campaign platforms, partner portals, and client-facing AI tools for law, manufacturing, and consulting 🔹 STACK TypeScript · Python · Next.js · React · Node OpenAI · Anthropic Claude · Gemini · DeepSeek · OpenRouter Vercel AI SDK · MCP · tool calling · structured outputs · prompt caching · evals Supabase / Postgres / pgvector · Redis · BullMQ · durable workflows Vercel · AWS · Cloudflare · Stripe Slack · ClickUp · HubSpot · Salesforce · Pipedrive · Apollo · Airtable · n8n · Make · Zapier 🔹 HOW I WORK I work like a product engineer, not a ticket-taker. I ask what outcome you're chasing, ship something usable fast, then harden it. You get clean commits, real docs, and a system your team can run without me. 📩 Tell me what you're trying to build. I'll tell you honestly whether it needs an AI agent, a data pipeline, or just better plumbing.
