What I build

AI systems that solve real problems.

Not prototypes — production systems with measurable outcomes.

AI Systems

Agents that work while you sleep.

LLM agents, RAG pipelines, and AI orchestration systems that automate complex decision-making. From autonomous SDR bots to document intelligence — production-grade, not toy demos.

  • Autonomous lead discovery & outreach
  • Document parsing & interpretation
  • Multi-step AI pipelines
Automation

Eliminate the repetitive. Ship the rest.

Custom bots, API integrations, and workflow automation that remove manual bottlenecks at scale. If a human is doing it repeatedly, it can be automated — and should be.

  • API & webhook integrations
  • Multi-step workflow automation
  • Data scraping & enrichment
Platforms

SaaS products ready to ship.

Full-stack web applications with auth, billing, and infrastructure. Built with Next.js, FastAPI, and PostgreSQL — production-ready from day one, not day ninety.

  • SaaS tools with Stripe billing
  • Internal operations dashboards
  • Customer-facing web apps
Work

Everything I've shipped.

AI systems, automation pipelines, SaaS products and platforms.
