Hey, I'm Nikola 👋 I spent 5+ years as a software engineer before moving into AI automation, including banking integrations for a $40M fintech company. Some recent work: → Lead gen system for Meta Ads specialists, got them 3x more leads. → Content and script generation system for coaching businesses and Youtubers, cut their content costs 20%. → Built a lead tracking platform from scratch (Next.js, Postgres) to replace a client's manual spreadsheet process. I also trained under Nick Saraev, who runs a $70K/month AI agency and has 227K subscribers on YouTube. If you need something that actually holds up in production, not just works in a demo, let's talk. Long version Hey, I'm Nikola. Before AI automation I worked as a software engineer for 5+ years, building production systems for fintech and enterprise clients. Part of that was banking API integrations for a $40M software company, powering financial services infrastructure across European banks and African fintech platforms. I moved into AI automation after that and trained under Nick Saraev, who built a $70K/month AI agency and has 227K subscribers on YouTube. Some of the systems I've built: A lead gen and outreach pipeline for Meta Ads specialists and recruitment agencies. Scrapes leads, qualifies them, reaches out across multiple channels. Got one client 3x more leads. A content and script generation system for coaching businesses. Cut their content production costs by 20%. A lead tracking platform built from scratch in Next.js and Postgres, replacing a client's manual CSV and spreadsheet process. n8n workflows with an AI agent handling email classification, drafting, and routing without anyone in the loop. CRM and API integrations connecting tools like Apollo, Apify, ChatGPT, and Claude into one pipeline. I like building things that keep working after the demo is over. If you tell me what's actually eating your time each week, I can tell you honestly whether automation fixes it, and what that would look like. Cheers, Nikola
