About
Next.js developer and full stack engineer with 6+ years of experience. I build web apps, SaaS products and startup MVPs with React and Next.js on Firebase or Supabase, handle Stripe integration and subscriptions, ship React Native Expo mobile apps, and add AI chatbots and OpenAI/Claude API features when your product needs them. Senior Software Engineer at a US AI EdTech company used across 20+ US schools. Top Rated Plus, 100% Job Success.
If you need someone to own the frontend, backend, database, payments and integrations of your product, or to turn a prototype that works in a demo into something that holds up in production, that is exactly the work I do.
FULL STACK DEVELOPMENT & SAAS
- Next.js (App Router), React and TypeScript front ends; Node.js and Python / FastAPI back ends
- Supabase and PostgreSQL: schema design, migrations, Row Level Security; Firebase / Firestore
- Stripe integration: subscriptions, idempotent webhooks, upgrades and downgrades, trials, grace periods
- Authentication, role-based access, admin dashboards, audited admin impersonation

AI ENGINEERING
- LLM features with structured outputs: content generation and grading with Claude, Gemini and OpenAI, typed JSON with automatic repair, and multi-provider failover
- RAG chatbots that stay grounded: pgvector, hybrid semantic + keyword search, per-tenant data isolation and citations
- AI agents: LangChain / LangGraph agents with scoped tools and streaming responses; MCP connectors that let Claude act inside a business app
- Quality and cost control: LLM-as-judge validation, prompt evaluations in CI with promptfoo, Langfuse tracing, per-call cost tracking
SELECTED WORK
