Technologies I Use to Deliver Results
My battle-tested stack for building AI products that scale.
Featured Projects
AI Behavior & Strategy Benchmark
ViralProblem: Businesses are choosing multi-million dollar AI models based on incomplete data. They test for capability but are blind to a model's character—its trustworthiness, strategic flaws, and potential for ruthless or naive behavior.
Solution: I built a full-stack platform that forces top LLMs into the Prisoner's Dilemma, creating the first public benchmark for their emergent strategic behavior.
Bookwiz.io
$3.3K MRRProblem: Authors and writers were struggling with writer's block and needed a tool that provided intelligent, context-aware assistance beyond simple grammar checks.
Solution: Built an agentic AI writing assistant from the ground up, with a complete SaaS platform including user management, Stripe payments, and a high-performance backend.
Vkashti.bar
Problem: A popular local bar was struggling with operational chaos, from reservations and inventory to staff coordination and customer engagement.
Solution: Developed a comprehensive web platform and AI-powered Discord bots to automate everything: reservations with SMS confirmations, staff task delegation, natural language inventory tracking, and even real-time quiz nights.
