I build and stabilize AI-native SaaS products with Claude Code, Cursor, Next.js, Supabase, RAG, and agent workflows. If you have a half-built AI product, messy Claude/Cursor-generated code, a Supabase app with weak RLS, or a founder-led SaaS that needs production features shipped fast, I can help you move from prototype to reliable production. My strongest work is at the intersection of full-stack engineering and AI systems: - Next.js 15 App Router, React, TypeScript, Tailwind, shadcn/ui - Supabase, Postgres, RLS, Auth, Edge Functions, pgvector - Stripe, Vercel, Railway, Netlify, GitHub, CI/CD, Sentry, PostHog - Claude, OpenAI, Gemini, Grok, DeepSeek, Ollama, vLLM - RAG pipelines, vector search, document ingestion, evals, guardrails - AI agents, tool calling, MCP servers, OpenAPI actions, workflow automation - Slack, WhatsApp, Telegram, Gmail, Google Sheets, Notion, Airtable, n8n I use Claude Code, Cursor, and Codex as serious engineering tools, not just autocomplete. That means maintaining project context, writing clear specs, reviewing generated code, testing edge cases, and turning AI-assisted work into clean commits and production-ready PRs. Common projects I can own end-to-end: - Add an AI assistant or chatbot to an existing SaaS - Build a RAG system over PDFs, websites, internal docs, or product data - Set up Supabase Auth, Postgres schemas, RLS policies, and user dashboards - Stabilize a Next.js/Supabase app with Stripe, Vercel, and production monitoring - Audit and refactor Claude Code or Cursor-generated code before production - Build internal AI tools for founders, operators, sales teams, and support teams - Create Slack, WhatsApp, Telegram, or email automations powered by LLMs - Design AI-native development workflows using CLAUDE.md, MCP, agents, and PR discipline I communicate clearly, work async, and can overlap 4+ hours with US Eastern time from IST. I am comfortable taking vague founder requirements, turning them into a practical technical plan, pushing back when needed, and shipping the version that should actually exist. If your goal is to ship an AI feature, harden an MVP, clean up an AI-generated codebase, or build a reliable agent/RAG workflow, I can step in and own the technical execution.
