Hello 👋

I ship production web apps and SaaS — from a free AI travel planner to multi-brand platform infrastructure that runs across seven consumer brands.

I work with founders and engineering teams who need someone who actually finishes things: architecture they can defend, deploy pipelines they can trust, and code their next hire can read.

If you have a product that needs to ship — or one that needs to stop falling over — let’s talk. 🚀

I've shipped AI features that actually work

Most AI projects fail because they treat the model as the product. I treat it as a component — wrapped in good prompt engineering, fallbacks, rate limits, and a UI that doesn't gaslight users when things go wrong.

  • Multi-provider AI orchestration

    On Aandar I built a thin orchestration layer so the team can swap between Claude, Gemini, OpenAI, or Groq with an env var. No vendor lock-in. No rewriting features when pricing changes.

  • Prompt engineering as a product surface

    JustBeforeGo turns a 5-step questionnaire into a structured prompt the model can't easily go off-rails on — that's the difference between a demo and something a real user trusts.

  • RAG that's actually useful

    For a Google + MongoDB workshop I built a full RAG pipeline — PDF ingestion, embeddings, vector search, cited responses. Same pattern lives inside Aandar's domain chatbot.
