Forward Deployed Engineer (FDE) · Senior AI Dev — LLM production deployment, Next.js / TypeScript
Available **3-4 days/week remotely**.
I work at the intersection of software development and AI: LLM integration, multi-step agents, RAG pipelines, production deployment. With 8 years of experience on SaaS projects, I help product teams move from "LLM prototype" to "production AI feature" — back-end architecture (Prisma, PostgreSQL, API Routes) and front-end interfaces (React, Tailwind, Next.js 15).
What sets me apart: aMaster's degree in Cognitive Psychologyapplied to development. Every interface I deliver is designed to reduce user cognitive load — not just to function.
Recent Projects:
- Entrepreneurial coaching SaaS (Next.js 15, GPT-4, Prisma) — integrated AI coach, 60+ models
- My Hypnosis Sheets — Spaced repetition SaaS (SM-2) for hypnotherapy practitioners
- Multi-tenant platforms: booking, forms, quotes, blog
I am looking for high-impact missions on growing products, particularly around AI deployment and SaaS architectures.
