About this gig

I design and build production-grade AI systems not prototypes that fall apart at scale.


As a full-stack AI Solutions Architect, I specialize in turning AI ideas into

real, revenue-ready software. My background spans multi-tenant SaaS platforms,

LLM inference layers, and agentic automation systems built with:


  • Backend: FastAPI, SQLAlchemy 2.0, Celery, PostgreSQL, Redis
  • Frontend: Next.js (App Router), TanStack Query, Zustand
  • AI/LLM: OpenAI-compatible APIs, RAG pipelines, model routing
  •   (Groq / vLLM / RunPod), LoRA fine-tuning & hot-swapping
  • Infrastructure: Docker, CI/CD, VPS + GPU server deployment,
  •   pluggable backends (no vendor lock-in)


WHAT I CAN HELP YOU WITH


  • AI architecture design & technical blueprints
  • LLM integration into existing products (chatbots, copilots, RAG search)
  • Multi-tenant AI SaaS backend development
  • Custom model routing & inference optimization
  • AI agent / automation workflow design
  • Scalable API design (auth, billing, usage metering)


WHY WORK WITH ME


I build for production from day one proper auth, rate limiting, error

handling, and clean abstractions not throwaway demo code. Let's discuss your project requirements.
