I help startups and growing businesses build, rescue, and scale production SaaS platforms. I enter existing codebases, find the biggest blockers, and ship fixes fast - without unnecessary rewrites. I build secure multi-tenant applications with Next.js, React, TypeScript, Node.js, Supabase/PostgreSQL, RLS, RBAC, OAuth, webhooks, and Stripe. I also build production AI features using OpenAI/Claude API, RAG, LangChain, tool calling, human-in-the-loop approvals, logging, and cost controls. What I can help with: AI SaaS and MVP development Existing codebase takeover, bug fixing, and production hardening Multi-tenant architecture, RLS, tenant isolation, and audit logs API integrations, OAuth, webhooks, background jobs, retries, and idempotency AI agents, RAG pipelines, OpenAI/Claude integrations, and tool calling Stripe payments, subscriptions, billing, and customer portals Admin dashboards, CRM platforms, internal tools, and analytics CI/CD, AWS/Vercel deployment, monitoring, and reliability Core stack: Next.js, React, TypeScript, Node.js, NestJS, PostgreSQL, Supabase, Prisma, MongoDB, Redis, Docker, AWS, Vercel, OpenAI API, Claude API, LangChain, Tailwind CSS. I focus on shipping fast while protecting security, data isolation, and production reliability.
