Hey, I'm Viktor 👋 I Will Automate Your Digital Business Operations in 11 Days. Send me a message to get started. -I'm currently saving over $30,000/m for a variety of agencies using custom CRM integrations and content systems that produce 15+ articles per day. -I work with Calo ($39M raised) to build an AI-powered customer support system. -I save 25+ hours every week using a lead triage, customer communication, and qualification system for a UK alloy wheel repair shop. -Automated approval workflows for a YouTube agency managing 700+ projects- Creative Director no longer bottlenecks production What changes for you: -Approvals, handoffs, and status updates happen without you -Leads get qualified, routed, and followed up on automatically -Your team operates from one source of truth instead of Slack threads and spreadsheets -You stop hiring for problems that automation solves How I work: I scope properly, deliver fast, and focus on measurable ROI. I underpromise and overdeliver. Whether you need an approval system for 20 projects or 700, I can help. I provide Loom updates throughout the project so you always know what's happening and what's next. Tools: n8n | Make | Asana | ClickUp | Monday | Airtable | API Integration | ChatGPT | Claude | Voice AI (Vapi) | GoHighLevel | Zapier Top Rated on Upwork. 100% Job Success Score. 40+ projects delivered. Send me a message if you're ready to stop being in the weeds. --- Extended Bio I've been on Upwork for about a year. Top Rated badge, 100% Job Success Score, 30+ projects completed. Before this, I ran a video editing agency serving astrology and spirituality creators. After ChatGPT launched, I started experimenting with how AI could optimize business workflows. I taught myself automation through free resources and structured programs- passed the full Make Academy, became n8n certified, and completed ClickUp's certification program. I've worked with clients across the US, Canada, UK, Germany, France, Portugal, Austria, Finland, Croatia, UAE, Bahrain, Australia, and the Philippines. Most of my clients are agencies and professional service firms drowning in operational chaos- founders who can't take a vacation without everything falling apart, teams waiting on approvals that bottleneck production, and businesses that could handle 30-50% more clients if their operations ran smoother. That's what I fix. My approach: I scope projects properly and manage expectations clearly. My motto: "You start as an uninformed optimist, then become an informed pessimist, and finally end up as a realistic optimist." I underpromise and overdeliver. I focus on fast delivery with measurable ROI. Most of my clients see thousands in monthly savings after systems go live. Communication: I provide regular updates- text for quick check-ins, Loom videos for walkthroughs. You'll always know what's happening, what's next, and what's needed from your side. The work I do: I build systems that run 24/7 without you. Approval automation so your Creative Directors don't bottleneck production. CRM systems so leads don't sit idle for 30 days. Client onboarding workflows so intake → consultation → engagement happens without manual handoffs. AI agents that qualify leads, answer customer questions, and book appointments. Voice agents that handle restaurant reservations and hotel bookings end-to-end. Complex n8n workflows with API integrations when off-the-shelf tools don't cut it. I work with your existing tools: Asana, ClickUp, Monday, Make, n8n- rather than forcing you to rebuild your stack. Augmentation, not replacement. If you're an agency owner tired of being the approval bottleneck, or a professional service firm losing revenue to manual operations, let's talk.

AI SaaS architect, senior full-stack developer, AI developer, and automation expert. I build LLM/RAG systems, AI agents, agentic workflows, ChatGPT and OpenAI integrations, and production SaaS platforms that ship in 2–4 weeks. No prototypes. No disappearing after handoff. Founders and CTOs don't call me first. They call after the offshore agency delivered a half-working prototype. After the generalist ran out of depth. When the stakes are too high to get it wrong again — that's when they call me. I work like a technical co-founder: I understand your business problem as clearly as the technical one. No account-manager layer, no junior handoff. You work directly with senior engineering across architecture, implementation, deployment, and the post-launch fixes that real systems always need. Over 70% of clients come back for another engagement — because trust is easier to earn through delivery than through proposals. 📈 PRODUCTION RESULTS ✅ n8n + GPT-4 replaced a 12-person workflow — 10,000+ records/day at 99.2% accuracy, saving $380K/year.
