Building Software, AI & Data Solutions That Solve Real Problems. AI Engineer and Full-Stack SaaS Developer building production AI agents, LLM apps, RAG systems and revenue-generating SaaS products, integrated with your data, CRM and workflows, with evals and guardrails built in. From first idea to a live product, I handle the full build: AI, backend, frontend, integrations, billing and deployment. You work with an engineer who owns the outcome and ships software your users rely on every day.
