Production AI agents, automation, and integration you own. Built into your stack, in your repo, handed over to you. Top Rated · 100% Job Success · 9+ years · Founder of ObjectSingle · EU-based, GDPR by default Flagship: VaultIQ+, a production multi-agent AI compliance platform. Days of due diligence to a cited report in minutes. OVERVIEW I am a technical founder with 9+ years building and shipping production software, and I lead the engineering team at ObjectSingle. I build custom AI you own: agents, RAG pipelines, and automation, integrated into your stack and handed over to you. Not no-code glue that breaks under load, and not research demos that never ship. You are not booking a freelancer by the hour. You get a senior, founder-led team. I scope and architect every project, stay hands-on through delivery, and you work with one accountable person from the first call to handover. WHAT I BUILD AI and automation AI agents and assistants: multi-step, stateful, integrated with your tools (CRM, support, internal systems). RAG and document intelligence: turn large document sets into cited, searchable answers. AI automation: remove manual, repetitive back-office and ops work. Days of work down to minutes. Software and product (9+ years) SaaS products: MVPs, dashboards, and multi-tenant apps, built to scale. Web and CMS: headless CMS and full-stack Next.js applications. Production deployment: built into your stack, in your repo and infrastructure, owned by you. PROOF VaultIQ+ (InsightX): a production multi-agent AI compliance platform that turns days of manual due diligence into a cited report in minutes. WTX: a B2B SaaS dashboard MVP, multi-tenant, built and shipped in 6 weeks. HOW I WORK Short discovery, then a fixed-scope build with clear milestones and weekly updates. Fixed price and fixed timeline. You keep the code, the stack, and the data. We ship in weeks, not quarters. WHO THIS IS FOR B2B and ecommerce companies (roughly $1M to $50M) with a concrete problem off-the-shelf tools cannot solve. EU-based delivery, GDPR by default, with Western-timezone overlap. TECH AI: Python, LangChain, RAG, OpenAI API, Anthropic Claude API, multi-agent systems. Product: Next.js, React, TypeScript, Node.js, Supabase. Commerce and CMS: Sanity, Contentful, Strapi, Shopify. FOCUS AREAS AI Integration, AI agents and agentic workflows, LLM and RAG integration, AI automation, AI product development, full-stack

Most ad accounts don’t fail because of traffic. They fail because of poor structure, weak positioning, and inconsistent decision-making. I work with businesses that need a senior-level media buyer to take ownership of performance across Google Ads and Meta Ads, not just someone to “manage campaigns”, but someone who understands how to scale responsibly. ⸻ 🎯 What I Do • Build high-performance Google & Meta campaign structures • Manage and optimize paid media budgets with clear ROI targets • Improve lead quality and revenue performance (not just CPL) • Align ads with business objectives, margins, and sales reality • Make data-driven decisions that reduce wasted spend I focus on account stability, scalability, and predictable growth. ⸻ 🧠 Background Before freelancing, I worked closely with Google and Meta advertising teams, supporting hundreds of SMB accounts and managing multi-million dollar ad portfolios. I understand: • platform mechanics • policy compliance (including healthcare & regulated sectors) • attribution challenges • scaling without breaking performance Certified in Google Ads & Meta Blueprint. ⸻ ⚙️ How I Work Audit → Structure → Optimize → Scale Clear KPIs. No vanity metrics. No guesswork. ⸻ 💬 Ideal Clients • Service-based businesses • High-ticket lead generation • Ecommerce brands scaling beyond testing • Companies investing $10k+/month in advertising If you’re looking for someone to take paid media seriously — and treat your ad budget like an investment, not an experiment — we’ll get along well. 📩 Feel free to invite me or send a message to discuss your goals.
