About
I'm Denis, a self-taught builder from Bosnia. I make AI systems that talk to real customers and move real money, not demos that only look good in a screenshot.
I work solo and end to end. I design it, write the code, set up the servers, and stay on it until the thing actually works in the wild. So far that has meant voice agents that call and close, software that reads the ad market, and automation that runs for weeks without anyone touching it.
One question matters to me more than any other: does it still work when nobody is watching. Most of what I build is answering a call or sending an email right now, without me in the room.
What I'm building
Founder · Voice AI
An AI receptionist and cold caller for local service businesses. It answers the missed call, qualifies the lead, books the job, and hands hot prospects to a closing agent. I built the whole pipeline: lead sourcing, call orchestration, the CRM behind it, and the payment flow. Its outreach arm, FormReach, fills contact forms across thousands of sites around the clock.
View on GitHub ↗Founder · SaaS
Ad intelligence software. It pulls competitor ads from public ad libraries and breaks down the hooks and angles with AI, so a marketer can see what is actually working before spending a dollar. Built as a TypeScript monorepo with a Next.js front end and worker services behind it.
View on GitHub ↗Founder · Voice Automation
An AI voice system that calls a business's old, dead leads and turns them back into booked work. It handles the outreach, the conversation, and the booking handoff on its own, on a schedule, with no one dialing.
View on GitHub ↗Founder · Lead Gen
An autonomous system that finds and qualifies businesses for workers comp premium audits, recruits audit firm partners, and routes the consults between them. It runs unattended with its own compliance engine, ML lead scoring, and live monitoring.
View on GitHub ↗Founder · Local SEO
A platform that spins up programmatic local SEO sites across cities and services, ranks them, captures leads, and sells them to local businesses. Thousands of pages built from structured data, plus an AI receptionist for inbound calls.
View on GitHub ↗Founder · Voice QA
A white-label voice QA and production pod for AI voice agencies. It finds quality issues in their voice deployments as the hook, then delivers the build and managed operations. Safety first, with every live action gated behind explicit approval.
