Hi, I'm Aleksandar πŸ‘‹

πŸ“ Munich ↔ Starnberg | 🧠 Marketing-ops native, AI-first builder | πŸ‡ͺπŸ‡Ί EU-hosted by default

TypeScript Next.js React Node.js Expo Claude OpenAI Supabase HubSpot n8n Docker

Deep in vibe-coding mode – after 15+ years of WordPress/WooCommerce, I've gone all-in on Next.js, React, and the LLM stack. Building the middle layer between marketing and engineering at ludicrous speed.

Current Projects

  • 🧠 Competitive Intelligence Platform – The AI that actually reads your competitors so you don't have to. Firecrawl + Vector DB + Helicone cost tracking.
  • 🌧️ Rain Prompt – Git, but for prompts. Store, share, subscribe.
  • 🎟️ Real-Time Seat Management – Reservations that survive nightlife hours (past midnight? handled).
  • πŸ“Έ AI Photo Booth – Scan QR, upload selfie, get branded AI overlay. Event marketing at vibe-speed.
  • 🎁 Gamified Advent Calendar – 24 days of HubSpot-native engagement with LinkedIn gifting automation.
  • πŸ“± Smart QR Generator – One link, right app store, zero device-sniffing headaches.
  • πŸ›οΈ Balkan Interior Designer – Regional architecture agent that remodels rooms with structural integrity intact.
  • 🎬 Personalized Xmas Videos – Gemini-generated greetings at marketing scale.
  • πŸ€– n8n Competitive Intel Agents – Decentralized scrapers feeding custom dashboards while I sleep.

The Stack

Now building with:

  • Frontend: Next.js, React, TypeScript, Expo/React Native
  • AI: Anthropic, OpenAI, Perplexity Sonar, Helicone for cost & latency
  • Data: Supabase (Vector), Postgres, Firecrawl, Unstructured.io
  • Infra: Vercel, Docker, Coolify – GDPR from day zero, not day 100
  • Marketing Ops: HubSpot (certified), n8n

Where I came from: WordPress, WooCommerce, PHP – 15+ years of it. Still fluent, rarely nostalgic.

🧰 Open-Source Toolbox

Free, self-hosted, solve-my-own-problem utilities. Fork away.

  • 🧠 apsolut-cortex (latest) – Persistent Claude Code memory for local dev. MCP-native, remembers what matters across sessions.
  • πŸ“Š sheetbuddy – Compare two lists, spot the diff. Match on email, ID, customer number – spreadsheet detective work, done.
  • πŸ“‹ pastekit – Define your copy-paste fields once, click to copy forever. For the person who types the same five things every day.
  • πŸ”– raindrop-mapping – Export Raindrop.io bookmarks with full collection + group hierarchy. Your tree, in CSV.

πŸ§ͺ In the Lab

  • πŸ“‘ Deep-Signal Marketing Intel – Triangulating what every data source sees separately. One signal is a hypothesis, three is a trend, six is a story worth taking to the CMO.
  • 🌐 Chrome APIs (Origin Trial) – Poking at the browser's bleeding edge. On-device AI, new web platform primitives, whatever Chrome ships next – tested before it lands.
  • πŸ“± Android + Electron Apps – Same logic, more surfaces. Web is great; pocket and desktop are next.

🏠 Homelab

Mini PCs humming in the corner, running my own cloud. Self-hosted by default – the best API is the one you control.

  • 🚒 Coolify – My personal PaaS. Vercel-style deploys on hardware I own, with bills that don't surprise me.
  • πŸ” n8n – Always-on automation. Glue between APIs, LLMs, scrapers, and my inbox.
  • 🦞 OpenClaw experiments – Running OpenClaw on bare metal. Autonomous agents, sandboxed, observed.
  • ✍️ Local writer agents – On-device LLMs drafting content. Private data, predictable costs, zero vendor rate limits.

What I'm Doing

  • Bridging marketing & engineering – Most "martech" is too marketing or too tech. I build the middle layer.
  • Shipping in days, not quarters – Vibe coding is real; the skill is knowing when to stop.
  • Privacy-first by reflex – EU hosting, data-minimal pipelines, GDPR-compliant by construction.
  • Exploring the agent stack – RAG, tool use, observability. Watching local LLMs get scary-good.

  • HubSpot Certified

Philosophy

"Automate the boring. Vibe-code the rest." – I build tools to solve problems I actually have, then hand them to the people who have the same problem but less time.

Random Facts

  • Based in 82319 Starnberg, Germany
  • Strong opinions about data-ga-* attribute taxonomies and schema.org markup
  • Ask me about BlogPosting vs WebPage – I have a 40-minute answer
  • Run Claude Code and n8n side-by-side all day
